Hi Folks,

I am having an issue with LVM on a 2 node cluster. We are using powerpath for external drives.

We had a request to increase /apps filesystem which is EXT3.

On the first node we did :
pvcreate /dev/emcpowercx1 and /dev/emcpowercw2
Then....
vgextend apps_vg /dev/emcpowercw2 /dev/emcpowercx1
lvresize -L +60G /dev/apps_vg/apps_lv
resize2fs /dev/apps_vg/apps_lv

everything went on well , we got the /apps increased.

But on the second node when i do pvs

I am getting following error:

WARNING: Duplicate VG name apps_vg: RnD1W1-peb1-JWay-MyMa-WJfb-41TE-cLwvzL (created here) takes precedence over ttOYXY-dY4h-l91r-bokz-1q5c-kn3k-MCvzUX


How can i proceed from here ??

ext3 is not a cluster aware filesystem so you really shouldn't be trying to share it between nodes.

Have a look at this article:

You might also want to have a look at this:

Essentially I'm seeing you need to run clvmd for cluster environments and that daemon propagates the changes.
