Problem removing a Volume Group

dictum9 — Mon, 30 Apr 2007 15:44:10 GMT

Any idea how to proceed? It complains about lvols, but I don't see any.

#: vgremove /dev/vgignite
vgremove: Volume group "/dev/vgignite" still contains a logical volume(s).
vgremove: Couldn't remove volume group "/dev/vgignite".
#:

#: vgdisplay -v /dev/vgignite

Your "Cur LV" still shows 1. Your "Free PE" on the drive is 390 and "TOTAL PE" is 3974. If there were no LVOLs configured the FREE PE should be the same as the TOTAL PE.

Do a 'strings /etc/lvmtab | more' and look for the section for this VG. See if an LV is listed.

If you really want to get rid of this VG and are absolutely sure it is not in use, do:

# vgexport /dev/vgignite

That should completely remove it.

any errors being displayed that you are not posting.. The vgdisplay shows 1 Cur LV..

try a vgexport -p -m /tmp/map.file and review the map file.

If you are absolutely sure nothing is there then vgexport .. Be carefull here before you choose the brute force approach. The system is usually right.

Shalom,

There are still logical volumes on this disk.

Since a disk can only be in one volume group, I'd conclude that lvremove is not complete.

pvdisplay -v /dev/dsk/c10t0d0 and get those logical volumes out of there.

Otherwise, vgexport.

Because Ignite is very concerned with restorability, it will not complete on systems with lvm problems.

It may seem like a pain, but it insures as best as you can that the thing will work when you need it.

# vgexport /dev/vgignite

that's what I was looking for.
Not sure where the inconsistency showed up from, probably from deleting something in the wrong way.

Hi

run vgexport /dev/vgignite

this will resolve the issue & it is safe too.
