Growing a mounted XFS filesystem | LinuC Level 1 101 Exam original practice question

1.05.3Basic

The LV containing XFS is already extended and mounted at /srv/media.

Grow XFS online to the current size of the lower device.

Which command is appropriate?

Hint 1: Focus on the requirement

Use the XFS growth utility with the mounted path, not the ext tool or a repair command.

Hint 2: Key terms

Review the short filesystem and storage definitions before comparing the choices.

Detailed explanation

Incorrectresize2fs /dev/vgdata/lvmedia

Incorrect. resize2fs is for ext filesystems, not XFS.

Incorrectxfs_repair /srv/media

Incorrect. xfs_repair checks and repairs rather than growing the mounted filesystem.

Incorrectmkfs.xfs /dev/vgdata/lvmedia

Incorrect. mkfs.xfs would recreate and potentially destroy the existing filesystem.

Correctxfs_growfs /srv/media

Correct. xfs_growfs /srv/media grows the mounted XFS filesystem.

An example you can run in a temporary verification environment.

xfs_growfs -V 2>&1

xfs_growfs versionの表示

Environment: xfsprogs xfs_growfs / バージョン表示のみ
Prefer help or version output and a disposable device when testing storage commands.
Formatting, repair, and mount changes can affect data or availability.

Foundation review

Online growth is distinct from offline repair and from creating a new filesystem.

Verify that the LV has already been extended and the filesystem is mounted.
