Configuring the mount point for the secondary HA host

You must configure the mount point on the secondary high-availability (HA) host for the file system that is moved to a Fibre Channel storage device.

Procedure

  1. Using SSH, log in to the secondary HA host as the root user.
  2. Derive the UUID by typing the following command:

    blkid /dev/<partition>

  3. Update the kernel with the Fibre Channel partition data by typing the following command:
    partprobe
    Troubleshoot: If you see a warning error message that the kernel cannot read the partition table, type the following command: ls -l /dev/disk/by-uuid/<UUID>. If no output is displayed, then restart the secondary HA host by typing reboot.
  4. If you are moving the /store directory, unmount the file systems by typing the following command:
    umount /store

    The /transient file system is mounted only when the /store file system is XFS.

  5. If you redirected the /store file system to an offboard device, choose one of the following options to edit the /etc/fstab file.
    • If the /store file system is an XFS file system, update the following lines. For each line, copy the text into a text editor, remove any line breaks, and paste as a single line.
      UUID=<uuid> /store xfs inode64,logbsize=256k,noatime,noauto 0 0
      
    • If the /store file system is ext4, update the following line:
      UUID=<uuid> /store ext4 defaults,noatime,noauto 0 0
  6. If you are moving the /store/ariel file system to an offboard device, choose one of the following options to edit the /etc/fstab file.
    • If the /store/ariel file system is an XFS file system, update the following lines. For each line, copy the text into a text editor, remove any line breaks, and paste as a single line.
      UUID=<uuid> /store/ariel xfs inode64,logbsize=256k,noatime,noauto 0 0
      
    • If the /store/ariel file system is ext4, update the following line:
      UUID=<uuid> /store/ariel ext4 defaults,noatime,noauto 0 0
  7. If you are moving the /store file system, rename the local copy of /store by typing the following command:
    lvchange -an /dev/storerhel/store 2>/dev/null
    lvrename /dev/storerhel/store /dev/storerhel/storeold 2>/dev/null
