• Checking and repairing filesystems: fsck, xfs_repair and btrfs check on an unmounted filesystem

  ext4, XFS and Btrfs each ship their own checker with different safety rules: e2fsck and xfs_repair must run on an unmounted filesystem (xfs_repair has a -n dry-run mode), while btrfs check defaults to read-only and warns strongly against --repair. Exit codes and dry-run output, not intuition, decide whether a repair is needed.

• Growing an LVM logical volume and its filesystem online without unmounting

  lvextend -r resizes a logical volume and its filesystem in one step while it stays mounted, calling xfs_growfs or resize2fs as appropriate. XFS filesystems can only ever grow, never shrink; this methodology covers the online-growth path for both.
