Repair and expand an XFS data volume

Diagnose a stale persistent mount, extend LVM safely, and verify both current and rebooted state.

Scenario brief

Orchard Lab's FILE-03 dropped into emergency mode after a disk replacement. An administrator mounted /srv manually to restore service, but /srv is now 95% full. Correct persistence and add 10 GiB without recreating or shrinking the XFS filesystem.

Complete the response

Partial credit is available for matching, ordering, and multi-select tasks.

01
single choice

What directly caused the failed automatic /srv mount?

3 pts
Need a hint?

Restate the exact outcome or failure the prompt asks about before comparing choices.

Show another hint

Eliminate choices that solve a nearby problem, change more than requested, or do not fit the evidence.

02
command

After fixing and validating fstab, enter one command that adds 10 GiB to the LV and grows its mounted XFS filesystem.

4 pts

Whitespace and capitalization are ignored when grading.

Need a hint?

Break the request into three parts: the action, the target, and the required constraint or verification.

Show another hint

Check the tool and subcommand first, then add only the flags, values, and paths the prompt requires.

03
ordering

Order the complete repair and expansion workflow.

5 pts

Drag the rows or use the arrow buttons to reorder.

  1. 1 Confirm backup/recovery access; record lsblk, findmnt, blkid, vgs/lvs, and filesystem state
  2. 2 Back up /etc/fstab and replace only the stale /srv UUID with 4c0e7c9a-2f5b-4ee2-9a7d-1bd9fcde4471
  3. 3 Run a persistent-mount validation such as findmnt --verify and test the entry without rebooting
  4. 4 Run the LV/filesystem growth command and watch for errors
  5. 5 Verify the new LV and XFS size, service access, and logs; then perform a controlled reboot and recheck /srv
Need a hint?

Identify the prerequisite that must happen first and the verification or documentation that belongs last.

Show another hint

For the middle steps, ask what must already be true before each action can safely happen.
