A systems administrator received a report about issues with a Linux system. Given the following output: Which of the following is the best command to use to fix this issue?

The correct answer is C. lvextend -L +5G -r /dev/mapper/rootvg-varlv. The output indicates the /var logical volume is running out of space. 'lvextend -L +5G -r /dev/mapper/rootvg-varlv' extends the logical volume by 5GB and the '-r' flag simultaneously resizes the underlying filesystem - all in one safe, non-destructive command.

Explanation

The output indicates the /var logical volume is running out of space. 'lvextend -L +5G -r /dev/mapper/rootvg-varlv' extends the logical volume by 5GB and the '-r' flag simultaneously resizes the underlying filesystem - all in one safe, non-destructive command. Option A (mkfs.xfs) would format /var, destroying all data. Option B (rm -rf /var/*) deletes all contents of /var, which would break the system. Option D targets rootlv, not varlv, so it would extend the wrong volume and not fix the reported issue.
