Re: lvextend

This LVOL is still mirrored, even if the disk is missing.

The system wants to extend the LVOL on one disk and the mirror too.

No disk = no extends available.

Consider to use "vgreduce -f vg00" to fix.

Hope this helps!
Regards
Torsten.

Re: lvextend

I think the two disks for this vg00 are c0t0d0s2 and c2t0d0s2...I conclude this from the vgdisplay -v /dev/vg00 output.

Also..I can see the c0t0d0s2 is present and c2t0d0s2 is missing.
how exactly should I remove the disk c2t0d0s2 from /dev/vg00

Before removing the disk from vg00 do I need to remove it from lv ?
It would be great if you explain me in steps. Thank you.

Re: lvextend

The lvol is still mirrored. Consider to use vgreduce -f or use the steps from here:

http://docs.hp.com/en/5991-1236/When_Good_Disks_Go_Bad_WP.pdf

in order to unmirror your lvols from a non-existing disk.

Hope this helps!

Torsten.

Re: lvextend

The PV has been removed from the VG
So lvreduce cant be done using the PV name.

lvdisplay -v -k /dev/vgxx/lvolxx gives the PV key(PV which has stale extents)

lvreduce -m 0 -A n -k /dev/vgxx/lvolxx

This successfully reduced the lvol.

The solution is in the 19th page
http://docs.hp.com/en/5991-1236/When_Good_Disks_Go_Bad_WP.pdf

Thanks to Torsten!
