I have a DRBD cluster with 2 nodes. I have the following experiment:
- i stop any cluster management so it can't interfere with my experiment
- drbd-overview shows both nodes resource secondary
- one node 1 i promote the resource to primary
- i mount it succesfully as ext4
- i unmount it and set it back to secondary
- i verify using drbd-overview that both nodes have the resource Connected
and UpToDate
- on node 2 i promote it to primary
- i try to mount it but there are filesystem errors that i need to fix with
I am puzzled how this is possible when node 1 cleanly unmounts, the
resource shows to be up-to-date but node 2 fails to mount it
Any suggestions will be greatly appreciated
