RHCSA RHCSA LVM Storage Management 5

Question 1

After importing physical disks from another system, which command makes the volume group available on the new system?

Accepted Answer

vgimport vg0 && vgchange -ay vg0

Answer

vgimport re-registers the VG with the system, then vgchange -ay activates it so LVs can be mounted.

Question 2

What is the purpose of the 'vgcfgrestore' command?

Accepted Answer

Restores VG metadata from an archived configuration file

Answer

vgcfgrestore restores the LVM metadata for a volume group from a backup stored in /etc/lvm/backup/.

Question 3

Which option with 'lvcreate' creates a thin-provisioned pool named 'thin_pool' in vg0?

Accepted Answer

Both A and C are correct

Answer

-T and --thin are equivalent flags for creating a thin pool; both commands produce the same result.

Question 4

A volume group shows 'partial' status. What does this indicate?

Accepted Answer

One or more PVs in the VG are missing or unavailable

Answer

A 'partial' VG means at least one physical volume member is missing, making some LV data inaccessible.

Question 5

Which lvs output column shows the type of a logical volume (e.g., linear, thin, snapshot)?

Accepted Answer

Attr

Answer

The 'Attr' column in lvs output encodes LV type and state using a multi-character attribute string.
