Subject: [linux-lvm] vgchange -an question with disconnected disks
Date: Thu, 02 Feb 2006 10:06:47 -0800 [thread overview]
Message-ID: <43E24A37.6010801@cup.hp.com> (raw)
I have a question regarding the behavior of vgchange -a n on lvm2 when
there are disk failures. Specifically the following:
1. vgchange -a y vg00
2. disconnect the disks
3. vgchange -a n vg00
Now this fails with many messages, such as:
[root@harris ~]# vgchange -a n vg00

Unable to find volume group "vg00"
[root@harris ~]#
This the vg is not deactivated. Now this is different behavior that with
lvm1 which would just proceed as normal. My question is that is there a
way to force the deactivation to occur in this case?
Thanks!
