[ClusterLabs] Removing DRBD w/out Data Loss?

[Eric Robinson]

I checked the DRBD manual for this, but didn't see an answer. We need to convert a DRBD cluster node into standalone server and remove DRBD without losing the data. Is that possible? I asked on the DRBD list but it didn't get much of a response.

Given:

The backing device is logical volume: /dev/vg1/lv1

The drbd volume is: drbd0

The filesystem is ext4 on /dev/drbd0

Since the filesystem is built on /dev/drbd0, not on /dev/vg1/lv1, if we remove drbd from the stack, how do we get access the data?
