[DRBD-user] Lower device is already claimed
From: Cameron Smith <velvetpixel_at_nospam>Date: Thu Mar 18 2010 - 16:04:23 GMT

I am experiencing the error:
"# drbdadm up r0
/dev/drbd1: Failure: (114) Lower device is already claimed. This usually
means it is mounted.
Command 'drbdsetup /dev/drbd1 disk /dev/sda2 /dev/sda6 0 --set-defaults
--create-device' terminated with exit code 10"
DRBD was syncing between node1 and node2 and when I rebooted node1 I got
this from cat/proc/drbd:
1:r0 Connected Secondary/Secondary Diskless/UpToDate
So I ran:
drbdadm up r0
and got the above error.
Is the lower device the actual partition the drbd device is on which is my
case is /dev/sda2?
Should that /dev/sda2 not be mounted at boot?
What do I do to make DRBD happy on reboot?
Thanks!
Cameron
