XK0-006 Practice Question: Based on the exhibit, what is the most likely…
Exhibit
Refer to the exhibit. [root@server ~]# lvm pvdisplay --- Physical volume --- PV Name /dev/sdb1 VG Name data_vg PV Size <500.00 GiB / not usable 4.00 MiB Allocatable yes PE Size 4.00 MiB Total PE 127999 Free PE 8192 Allocated PE 119807 PV UUID abc123-... PV Status not available
Based on the exhibit, what is the most likely cause of the 'PV Status: not available'?
⚠ Common exam trap
Test-takers frequently confuse 'PV Status: not available' with LVM metadata corruption, but the status specifically indicates the device is inaccessible, not that its metadata is damaged.

Correct answer & explanation
✓
The physical volume is missing or disconnected.
The 'PV Status: not available' message in LVM indicates that the system cannot access the physical volume. This typically occurs when the underlying disk or partition is missing, disconnected, or has failed. Since LVM relies on the physical volume being present for volume group and logical volume operations, a missing or disconnected physical volume is the most direct cause.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The volume group is corrupted.
Why it's wrong here
VG corruption would typically show different errors.
- ✗
The logical volume is not mounted.
Why it's wrong here
Mount status does not affect PV availability.
- ✗
LVM metadata is damaged.
Why it's wrong here
Damaged metadata would show metadata errors, not simply unavailable.
- ✓
The physical volume is missing or disconnected.
Why this is correct
PV status 'not available' indicates the PV cannot be accessed.
