stale PV

[UniRock]

Hi Everybody,
This is not a fully functional servwr but has following error, what should be my corrective steps. Certain PVs are showing "stale"

Hello,

Look at these two values.

Cur PV 4
Act PV 2

It is clearly showing there are physical volumes issue. Check all the physical volumes belongs to VG01 shows claimed on ioscan. If it is online then there is mismatch between /etc/lvmtab and kernel LVM data.

In that case it is possible that LVM headers may corrupt on the missing PV's. you may have to restore the LVM headers from backup using vgcfgrestore.

Try vgcfgrestore -n vg01 -l to confirm these missed PV's belongs to VG01

Hope this helps

thanks Ganesan, i used vgfcgrestore and indeed fixed the problem.
