Sorry for cross-posting this, but I'm not sure which list is the right one.
I'm not seeing anything on Google about this. Two DRBD nodes lost communication with each other, and then reconnected and started sync. But then it got to 100% and is just stalled there.
The nodes are 001db03a, 001db03b.
On 001db03a:
[root at 001db03a ~]# drbdadm status
ha01_mysql role:Primary
disk:UpToDate
001db03b role:Secondary
replication:SyncSource peer-disk:Inconsistent done:100.00
ha02_mysql role:Secondary
disk:UpToDate
001db03b role:Primary
peer-disk:UpToDate
On 001drbd03b:
[root at 001db03b ~]# drbdadm status
ha01_mysql role:Secondary
disk:Inconsistent
001db03a role:Primary
replication:SyncTarget peer-disk:UpToDate done:100.00
ha02_mysql role:Primary
disk:UpToDate
001db03a role:Secondary
peer-disk:UpToDate
On 001db03a, here are the DRBD messages from the onset of the problem until now.
