Mounting an NFS File System to ECSs (Linux)

-

After creating a file system, you need to mount the file system to servers so that they can share the file system.

-

In this section, ECSs are used as example servers. Operations on BMSs and containers (CCE) are the same as those on ECSs.

-

Prerequisites

-
-

Procedure

  1. Log in to the management console using a cloud account.

    1. Log in to the management console and select a region and a project.
    2. Under Computing, click Elastic Cloud Server to go to the ECS console.
    -

  2. Log in to the ECS as user root.

    If you log in to the ECS as a non-root user, see Mounting a File System to a Linux ECS as a Non-root User.

    -
    -

  3. Install the NFS client.

    1. Run the following command to check whether the NFS software package is installed.
      • On CentOS, Red Hat, Oracle Enterprise Linux, SUSE, EulerOS, Fedora, or OpenSUSE:

        rpm -qa|grep nfs

        -
      • On Debian or Ubuntu:

        dpkg -l nfs-common

        -
      -
      If a command output similar to the following is displayed, the NFS software package has been installed and you can go to 4. If nothing is displayed, go to 3.b.
      • On CentOS, Red Hat, EulerOS, Fedora, or Oracle Enterprise Linux:
        libnfsidmap
-nfs-utils
        -
      • On SUSE or OpenSUSE:
        nfsidmap
-nfs-client
        -
      • On Debian or Ubuntu:
        nfs-common
        -
      -
      -
    2. Run the following command to install the NFS software package.

      The following commands require that ECSs be connected to the Internet. Or, the installation will fail. Installing NFS clients requires enabling effective software repositories. Installing NFS clients will fail if no software repository is enabled or the ECS does not have any software repository. If installing NFS clients fails, refer to Enabling or Adding a Software Repository.

      -
      -
      • On CentOS, Red Hat, EulerOS, Fedora, or Oracle Enterprise Linux:

        sudo yum -y install nfs-utils

        -
      • On Debian or Ubuntu:

        sudo apt-get install nfs-common

        -
      • On SUSE or OpenSUSE:

        zypper install nfs-client

        -
      -
    -

  4. Run the following command to check whether the domain name in the file system mount point can be resolved. SFS Turbo file systems do not require domain name resolution. Skip this step and directly mount the file system.

    nslookup File system domain name

    -
    • A file system domain name is just a part of the mount point, for example, sfs-nas1.xxxx.com. You can obtain a file system domain name from the mount point of a file system. In this step, you are not supposed to enter the entire mount point but only the domain name.
    • If the nslookup command cannot be used, install the bind-utils software package by running the yum install bind-utils command.
    -
    -
    • If the domain name can be resolved, go to 5.
    • If the domain name cannot be resolved, configure the DNS server IP address and then mount the file system. For details, see Configuring DNS.
    -

  5. Run the following command to create a local path for mounting the file system:

    mkdir Local path

    -

    If there is any resource, such as a disk, already mounted on the local path, create a new path. (NFS clients do not refuse repeated mounts. If there are repeated mounts, information of the last successful mount is displayed.)

    -
    -

  6. Run the following command to mount the file system to the ECS that belongs to the same VPC as the file system. Currently, the file system can be mounted to Linux ECSs using NFSv3 only.

    Table 1 describes the variables.

    -

    To mount an SFS Capacity-Oriented file system, run the following command: mount -t nfs -o vers=3,timeo=600,noresvport,nolock Mount point Local path

    -

    To mount an SFS Turbo file system, run the following command: mount -t nfs -o vers=3,timeo=600,noresvport,nolock Mount point Local path

    -

    After an ECS where file systems have been mounted restarts, it loses the file system mount information. You can configure automatic mount in the fstab file to ensure that an ECS automatically mounts file systems when it restarts. For details, see Mounting a File System Automatically.

    -
    -
    - - - - - - - - - - - - - - - - - - - - - - -
    Table 1 Parameter description

    Parameter

    -

    Description

    -

    vers

    -

    File system version. Only NFSv3 is supported currently, so the value is fixed to 3.

    -

    timeo

    -

    Waiting time before the NFS client retransmits a request. The unit is 0.1 second. The recommended value is 600.

    -

    resvport/noresvport

    -

    Whether the confidential source port is used for server connection. By default, resvport indicates that the confidential port is used, and noresvport indicates that the confidential port is not used. The kernel version is 2.6.28 or later.

    -

    You are advised to set this parameter to noresvport so that a new TCP port can be used when the network is reconnected. This ensures that the connection is not interrupted when the network recovers from a fault.

    -

    lock/nolock

    -

    Whether to lock files on the server using the NLM protocol. If nolock is selected, the lock is valid for applications on one host. For applications on another host, the lock is invalid. The recommended value is nolock. If this parameter is not specified, lock is selected by default. In this case, other servers cannot write data to the file system.

    -

    Mount point

    -

    The format for an SFS Capacity-Oriented file system is File system domain name:/Path, for example, example.com:/share-xxx. The format for an SFS Turbo file system is File system IP address:/, for example, 192.168.0.0:/.

    -

    See Figure 1.

    -
    NOTE:
    • x is a digit or letter.
    • If the mount point is too long to display completely, you can adjust the column width.
    • Hover the mouse over the mount point to display the complete mount command.
    -
    -

    Local path

    -

    Local path on the ECS, used to mount the file system, for example, /local_path.

    -
    -
    -
    -
    Figure 1 Mount point

    For more mounting parameters for performance optimization during file system mounting, see Table 2. Use commas (,) to separate parameters. The following command is an example:

    -

    mount -t nfs -o vers=3,timeo=600,nolock,rsize=1048576,wsize=1048576,hard,retrans=3,noresvport,ro,async,noatime,nodiratime Mount point Local path

    Table 2 Parameters for file system mounting

    Parameter

    -

    Description

    -

    rsize

    -

    Maximum number of bytes that can be read from the server each time. The actual data is less than or equal to the value of this parameter. The value of rsize must be a positive integer that is a multiple of 1024. If the entered value is smaller than 1024, the value is automatically set to 4096. If the entered value is greater than 1048576, the value is automatically set to 1048576. By default, the setting is performed after the negotiation between the server and the client.

    -

    You are advised to set this parameter to the maximum value 1048576.

    -

    wsize

    -

    Maximum number of bytes that can be written to the server each time. The actual data is less than or equal to the value of this parameter. The value of wsize must be a positive integer that is a multiple of 1024. If the entered value is smaller than 1024, the value is automatically set to 4096. If the entered value is greater than 1048576, the value is automatically set to 1048576. By default, the setting is performed after the negotiation between the server and the client.

    -

    You are advised to set this parameter to the maximum value 1048576.

    -

    soft/hard

    -

    soft indicates that a file system is mounted in soft mount mode. In this mode, if an NFS request times out, the client returns an error to the invoking program. hard indicates that a file system is mounted in hard mount mode. In this mode, if the NFS request times out, the client continues to request until the request is successful.

    -

    The default value is hard.

    -

    retrans

    -

    Number of retransmission times before the client returns an error.

    -

    ro/rw

    -
    • ro: indicates that the file system is mounted as read-only.
    • rw: indicates that the file system is mounted as read/write.
    -

    The default value is rw. If this parameter is not specified, the file system will be mounted as read/write.

    -

    resvport/noresvport

    -

    Whether the confidential source port is used for server connection. By default, resvport indicates that the confidential port is used, and noresvport indicates that the confidential port is not used. The kernel version is 2.6.28 or later.

    -

    You are advised to set this parameter to noresvport so that a new TCP port can be used when the network is reconnected. This ensures that the connection is not interrupted when the network recovers from a fault.

    -

    sync/async

    -

    sync indicates that data is written to the server immediately. async indicates that data is first written to the cache before being written to the server.

    -

    Synchronous write requires that an NFS server returns a success message only after all data is written to the server, which brings long latency. The recommended value is async.

    -

Mounting an NFS File System to ECSs (Linux)

+

After creating a file system, you need to mount the file system to servers so that they can share the file system.

+

In this section, ECSs are used as example servers. Operations on BMSs and containers (CCE) are the same as those on ECSs.

+

Prerequisites

+
+

Procedure

  1. Log in to the management console using a cloud account.

    1. Log in to the management console and select a region and a project.
    2. Under Computing, click Elastic Cloud Server to go to the ECS console.
    +

  2. Log in to the ECS as user root.

    If you log in to the ECS as a non-root user, see Mounting a File System to a Linux ECS as a Non-root User.

    +
    +

  3. Install the NFS client.

    1. Run the following command to check whether the NFS software package is installed.
      • On CentOS, Red Hat, Oracle Enterprise Linux, SUSE, EulerOS, Fedora, or OpenSUSE:

        rpm -qa|grep nfs

        +
      • On Debian or Ubuntu:

        dpkg -l nfs-common

        +
      +
      If a command output similar to the following is displayed, the NFS software package has been installed and you can go to 4. If nothing is displayed, go to 3.b.
      • On CentOS, Red Hat, EulerOS, Fedora, or Oracle Enterprise Linux:
        libnfsidmap
+nfs-utils
        +
      • On SUSE or OpenSUSE:
        nfsidmap
+nfs-client
        +
      • On Debian or Ubuntu:
        nfs-common
        +
      +
      +
    2. Run the following command to install the NFS software package.

      The following commands require that ECSs be connected to the Internet. Or, the installation will fail. Installing NFS clients requires enabling effective software repositories. Installing NFS clients will fail if no software repository is enabled or the ECS does not have any software repository. If installing NFS clients fails, refer to Enabling or Adding a Software Repository.

      +
      +
      • On CentOS, Red Hat, EulerOS, Fedora, or Oracle Enterprise Linux:

        sudo yum -y install nfs-utils

        +
      • On Debian or Ubuntu:

        sudo apt-get install nfs-common

        +
      • On SUSE or OpenSUSE:

        zypper install nfs-client

        +
      +
    +

  4. Run the following command to check whether the domain name in the file system mount point can be resolved. SFS Turbo file systems do not require domain name resolution. Skip this step and directly mount the file system.

    nslookup File system domain name

    +
    • A file system domain name is just a part of the mount point, for example, sfs-nas1.xxxx.com. You can obtain a file system domain name from the mount point of a file system. In this step, you are not supposed to enter the entire mount point but only the domain name.
    • If the nslookup command cannot be used, install the bind-utils software package by running the yum install bind-utils command.
    +
    +
    • If the domain name can be resolved, go to 5.
    • If the domain name cannot be resolved, configure the DNS server IP address and then mount the file system. For details, see Configuring DNS.
    +

  5. Run the following command to create a local path for mounting the file system:

    mkdir Local path

    +

    If there is any resource, such as a disk, already mounted on the local path, create a new path. (NFS clients do not refuse repeated mounts. If there are repeated mounts, information of the last successful mount is displayed.)

    +
    +

  6. Run the following command to mount the file system to the ECS that belongs to the same VPC as the file system. Currently, the file system can be mounted to Linux ECSs using NFSv3 only.

    Table 1 describes the variables.

    +

    To mount an SFS Capacity-Oriented file system, run the following command: mount -t nfs -o vers=3,timeo=600,noresvport,nolock Mount point Local path

    +

    To mount an SFS Turbo file system, run the following command: mount -t nfs -o vers=3,timeo=600,noresvport,nolock Mount point Local path

    +

    After an ECS where file systems have been mounted restarts, it loses the file system mount information. You can configure automatic mount in the fstab file to ensure that an ECS automatically mounts file systems when it restarts. For details, see Mounting a File System Automatically.

    +
    +
    +
    + + + + + + + + + + + + + + + + + + + + + + +
    Table 1 Parameter description

    Parameter

    +

    Description

    +

    vers

    +

    File system version. Only NFSv3 is supported currently, so the value is fixed to 3.

    +

    timeo

    +

    Waiting time before the NFS client retransmits a request. The unit is 0.1 second. The recommended value is 600.

    +

    resvport/noresvport

    +

    Whether the confidential source port is used for server connection. By default, resvport indicates that the confidential port is used, and noresvport indicates that the confidential port is not used. The kernel version is 2.6.28 or later.

    +

    You are advised to set this parameter to noresvport so that a new TCP port can be used when the network is reconnected. This ensures that the connection is not interrupted when the network recovers from a fault.

    +

    lock/nolock

    +

    Whether to lock files on the server using the NLM protocol. If nolock is selected, the lock is valid for applications on one host. For applications on another host, the lock is invalid. The recommended value is nolock. If this parameter is not specified, lock is selected by default. In this case, other servers cannot write data to the file system.

    +

    Mount point

    +

    The format for an SFS Capacity-Oriented file system is File system domain name:/Path, for example, example.com:/share-xxx. The format for an SFS Turbo file system is File system IP address:/, for example, 192.168.0.0:/.

    +

    See Figure 1.

    +
    NOTE:
    • x is a digit or letter.
    • If the mount point is too long to display completely, you can adjust the column width.
    • Hover the mouse over the mount point to display the complete mount command.
    +
    +

    Local path

    +

    Local path on the ECS, used to mount the file system, for example, /local_path.

    +
    +
    +
    +
    Figure 1 Mount point
    +

    For more mounting parameters for performance optimization during file system mounting, see Table 2. Use commas (,) to separate parameters. The following command is an example:

    +

    mount -t nfs -o vers=3,timeo=600,nolock,rsize=1048576,wsize=1048576,hard,retrans=3,noresvport,ro,async,noatime,nodiratime Mount point Local path

    + +
    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    Table 2 Parameters for file system mounting

    Parameter

    +

    Description

    +

    rsize

    +

    Maximum number of bytes that can be read from the server each time. The actual data is less than or equal to the value of this parameter. The value of rsize must be a positive integer that is a multiple of 1024. If the entered value is smaller than 1024, the value is automatically set to 4096. If the entered value is greater than 1048576, the value is automatically set to 1048576. By default, the setting is performed after the negotiation between the server and the client.

    +

    You are advised to set this parameter to the maximum value 1048576.

    +

    wsize

    +

    Maximum number of bytes that can be written to the server each time. The actual data is less than or equal to the value of this parameter. The value of wsize must be a positive integer that is a multiple of 1024. If the entered value is smaller than 1024, the value is automatically set to 4096. If the entered value is greater than 1048576, the value is automatically set to 1048576. By default, the setting is performed after the negotiation between the server and the client.

    +

    You are advised to set this parameter to the maximum value 1048576.

    +

    soft/hard

    +

    soft indicates that a file system is mounted in soft mount mode. In this mode, if an NFS request times out, the client returns an error to the invoking program. hard indicates that a file system is mounted in hard mount mode. In this mode, if the NFS request times out, the client continues to request until the request is successful.

    +

    The default value is hard.

    +

    retrans

    +

    Number of retransmission times before the client returns an error.

    +

    ro/rw

    +
    • ro: indicates that the file system is mounted as read-only.
    • rw: indicates that the file system is mounted as read/write.
    +

    The default value is rw. If this parameter is not specified, the file system will be mounted as read/write.

    +

    resvport/noresvport

    +

    Whether the confidential source port is used for server connection. By default, resvport indicates that the confidential port is used, and noresvport indicates that the confidential port is not used. The kernel version is 2.6.28 or later.

    +

    You are advised to set this parameter to noresvport so that a new TCP port can be used when the network is reconnected. This ensures that the connection is not interrupted when the network recovers from a fault.

    +

    sync/async

    +

    sync indicates that data is written to the server immediately. async indicates that data is first written to the cache before being written to the server.

    +

    Synchronous write requires that an NFS server returns a success message only after all data is written to the server, which brings long latency. The recommended value is async.

    +

    noatime

    +

    If you do not need to record the file access time, set this parameter. This prevents overheads caused by access time modification during frequent access.

    +

    nodiratime

    +

    If you do not need to record the directory access time, set this parameter. This prevents overheads caused by access time modification during frequent access.

    +
    +
    +

    You are advised to use the default values for the parameters without usage recommendations.

    +
    +

  7. Run the following command to view the mounted file system:

    mount -l

    +
    If the command output contains the following information, the file system has been mounted.
    Mount point on /local_path type nfs (rw,vers=3,timeo=600,nolock,addr=)
    +
    +

  8. After the file system is mounted successfully, access the file system on the ECSs to read or write data.

    If the mounting fails or times out, rectify the fault by referring to Troubleshooting.

    +

    The maximum size of a file that can be written to an SFS Capacity-Oriented file system is 240 TB.

    +

    The maximum size of a file that can be written to an SFS Turbo file system is 32 TB, and that for an SFS Turbo Enhanced file system is 320 TB.
