Resizing a partition and file system

This manual procedure must only be undertaken by an experienced Linux system administrator.

These are potentially destructive operations and there is the risk that the datastore or filesystems will be unrecoverable. Any errors or warnings encountered that are not documented here must be resolved before continuing to the next step.


This procedure assumes the following:

  • the datastore is stored in /mnt/addm/db_data
  • /mnt/addm/db_data is mounted on the /dev/sdb2 partition
    • the result of moving the datastore, including the creation of a swap partition, to a second disk using Disk Management
  • LVM has not been used to partition the disk

The following examples use the host testhost, and the tideway or root user as applicable.

To resize a partition and file system

  1. Create a backup of the appliance. The backup should be stored on a different machine.
  2. Log in to the appliance command line as the tideway user.

  3. Stop the Discovery services from starting on reboot. Enter the following commands:

    [tideway@testhost] $ tw_service_control --stop
    [tideway@testhost] $ sudo /bin/systemctl disable cluster
    [tideway@testhost] $ sudo /bin/systemctl disable omniNames

    Example output to show current partition size:

    [root@localhost ~]# df -h
    Filesystem      Size  Used Avail Use% Mounted on
    /dev/sda3       4.8G  1.2G  3.4G  26% /
    devtmpfs        1.9G     0  1.9G   0% /dev
    tmpfs           1.9G     0  1.9G   0% /dev/shm
    tmpfs           1.9G  8.6M  1.9G   1% /run
    tmpfs           1.9G     0  1.9G   0% /sys/fs/cgroup
    tmpfs           2.0G  880K  2.0G   1% /tmp
    /dev/sda5       4.8G   20M  4.5G   1% /reserved
    /dev/sda6       1.9G  6.0M  1.8G   1% /home
    /dev/sda1       711M  124M  535M  19% /boot
    /dev/sda7       1.7G  139M  1.5G   9% /var
    /dev/sda10       40G  2.8G   35G   8% /usr/tideway
    /dev/sda8       1.2G   12M  1.1G   2% /var/log
    /dev/sda9       852M  3.9M  788M   1% /var/log/audit
    tmpfs           380M     0  380M   0% /run/user/1000
    /dev/sdb2       187G  2.8G  174G   2% /mnt/addm/db_data
    [root@testhost ~]#
  4. Shutdown the Discovery virtual machine and wait for the system to completely power off.
  5. Increase disk size. In the examples, it is /dev/sdb that is enlarged.
  6. Start the Discovery virtual machine.
  7. Log in to the appliance command line as the tideway user and become the root user.

  8. Unmount the datastore partition:

    [root@testhost ~]# umount /mnt/addm/db_data

  9. Perform a check on the datastore filesystem:

    [root@testhost ~]# e2fsck -f /dev/sdb2
    e2fsck 1.41.12 (17-May-2010)
    Pass 1: Checking inodes, blocks, and sizes
    Pass 2: Checking directory structure
    Pass 3: Checking directory connectivity
    Pass 4: Checking reference counts
    Pass 5: Checking group summary information
    /dev/sdb2: 850/25247744 files (3.2% non-contiguous), 2344921/50475264 blocks
    [root@testhost ~]#

    Any errors reported must be resolved before continuing.

  10. Disable any swap on the same disk:

    1. Find swap partitions running on /dev/sdb

      [root@testhost ~]# swapon --summary
      Filename Type Size Used Priority
      /dev/sda2 partition 8388604 0 -1
      /dev/sdb1 partition 7811068 0 -2
      [root@testhost ~]#

    2. The swap partition /dev/sdb1 shares the disk, /dev/sdb, with the datastore. This must be disabled.

      [root@testhost ~]# swapoff /dev/sdb1
      [root@testhost ~]# swapon --summary
      Filename                                Type            Size    Used    Priority
      /dev/sda2                               partition       8388604 0       -1
      [root@testhost ~]#
  11. Resize the partition, using all available space at the end of the disk.

    1. Find the required disk information. Take note of the partition Number and the Start sector from the output, which are 2 and 15624192 respectively in the example. The example shows user input after the (parted) prompt.

      [root@testhost ~]# parted /dev/sdb
      GNU Parted 2.1
      Using /dev/sdb
      Welcome to GNU Parted! Type 'help' to view a list of commands.
      (parted) unit s
      (parted) print
      Model: VMware Virtual disk (scsi)
      Disk /dev/sdb: 536870912s
      Sector size (logical/physical): 512B/512B
      Partition Table: gpt

      Number  Start      End         Size        File system     Name     Flags

      2      15624192s  419428351s  403802112s  ext4            primary

      You may receive the errors and warnings noted below. You must enter Fix and <enter> to both options as these are expected when increasing disk size. The example shows user input after the Fix/Cancel prompt and the Warning: text.

      Error: The backup GPT table is not at the end of the disk, as it should be.  This
      might mean that another operating system believes the disk is smaller.  Fix, by
      moving the backup to the end (and removing the old backup)?
      Fix/Cancel? Fix

      Warning: Not all of the space available to /dev/sdb appears to be used, you can

      fix the GPT to use all of the space (an extra 117440512 blocks) or continue with
      the current setting? Fix


    2. Resize the partition Number noted above and use 100% as the option to use all remaining disk space. The example shows user input after the (parted) prompt.

      (parted) resizepart 2
      End?
      (parted) 100%
      (parted) print

      (parted) quit
      Information: You may need to update /etc/fstab.

      [root@testhost ~]#

    3. Check the partition's filesystem for errors.

      [root@testhost ~]# e2fsck -f /dev/sdb2
      e2fsck 1.41.12 (17-May-2010)
      Pass 1: Checking inodes, blocks, and sizes
      Pass 2: Checking directory structure
      Pass 3: Checking directory connectivity
      Pass 4: Checking reference counts
      Pass 5: Checking group summary information
      /dev/sdb2: 850/25247744 files (3.2% non-contiguous), 2344921/50475264 blocks
      [root@testhost ~]#

      Any errors reported must be resolved before continuing.

    4. Resize the /dev/sdb2 filesystem to use the entire partition:

      [root@testhost ~]# resize2fs /dev/sdb2
      resize2fs 1.41.12 (17-May-2010)
      Resizing the filesystem on /dev/sdb2 to 65155579 (4k) blocks.
      The filesystem on /dev/sdb2 is now 65155579 blocks long.

      [root@testhost ~]#

    5. Check the partition's filesystem to ensure the resize operation did not cause any corruption.

      [root@testhost ~]# e2fsck -f /dev/sdb2
      e2fsck 1.41.12 (17-May-2010)
      Pass 1: Checking inodes, blocks, and sizes
      Pass 2: Checking directory structure
      Pass 3: Checking directory connectivity
      Pass 4: Checking reference counts
      Pass 5: Checking group summary information
      /dev/sdb2: 850/32587776 files (3.2% non-contiguous), 2804569/65155579 blocks
      [root@testhost ~]#

    6. Confirm the /etc/fstab file will mount the resized partition correctly. The blkid command will show the UUID of the partition which needs to match the UUID used in /etc/fstab for /mnt/addm/db_data. If the UUID is not the same, the /etc/fstab file will need to be updated. If /dev/sdb2 is used rather than UUID, there is no need to update /etc/fstab.

      [root@testhost ~]# blkid /dev/sdb2
      /dev/sdb2: UUID="fe656744-9995-4494-87f6-90eed0df80e5" TYPE="ext4"

  12. Reboot the Discovery virtual machine.
  13. Log in to the appliance command line as the tideway user.

  14. Confirm after restart that the partition has mounted as expected:

  15. Start the tideway services:

    [tideway@localhost] $ sudo /bin/systemctl start omniNames
    [tideway@localhost] $ sudo /bin/systemctl start cluster
    [tideway@localhost] $ tw_service_control --start

  16. Log on to the Discovery UI. If the UI is available and not showing any errors then re-enable the cluster and omniNames services on startup.

    [tideway@testhost ~] $ sudo /bin/systemctl enable cluster
    [tideway@testhost ~] $ sudo /bin/systemctl enable omniNames
    [tideway@testhost ~] $
  17. Finally, reboot the appliance.
