LVM Problem

[shashi kanth]

I made a mistake with LVM, i enabled a VG in a 2-node service guard cluster with read-write, and i deleted VG in one node, and i am not able to delete that VG in the 2nd node.

In the 2nd node, if i try to delete a VG, it throws bellow error.

# vgchange -a y -q n -s -l /dev/lvm_fail

I am not able to activate VG in the 2nd node to remove the VG.

How can i remove the VG in my 2nd node ?

# pvremove /dev/rdsk/c4t0d5
pvremove: The physical volume "/dev/rdsk/c4t0d5" belongs to volume group "/dev/lvm_fail".
pvremove: Couldn't remove physical volume "/dev/rdsk/c4t0d5".

I don't know what you did on node1, but why not trying with vgexport?

[Patrick Wallek]

Try 'vgexport'.

# vgexport /dev/lvm_fail

Hi Shashi kanth,

Simply export the vg from second node if you don't need it any more.

#vgexport -v vgname

Thank you all.

With vgexport, it's gone.

Thanks.
