i know that this was already discussed on this ml, but i didn't find any
the situation is the following:
LVM filter: "filter = [ "a/dev/drbd[0-9]/","r|/dev/md[0-9]|" ]"
Now, i'm trying to setup LVM on top of drbd0.
Everything works fine untill i create the first logical volume.
I run "pvcreate /dev/drbd0" and "vgcreate vg00 /dev/drbd0"
If i reboot the two nodes, the next time everything is at its own place,
and drbd works as espected.
And the same occours when i run "lvcreate -L1GB -n test vg00", on the
When the operation is completed i can find "test" on the second node.
But...when i reboot the two nodes i receive an odd:
"Failure: (144) Lower device is already claimed. This usually means it
The device is not mounted, but i guess that LVM is grabbing it and
associate it with /dev/md1.
So, i now suspect that it is a lvm related issue because if i change the
lvm filter into "filter = [ "a/.*/" ]" i can find again my PV on MD1
any hints? :(
