[DRBD-user] Node1 Standalone Inconsistent/Outdated Node 2 WFConnection Inconsisten/DUnknown - how to recover?

[Ron]

Hi,

I've inherited a setup that has been running for a very long time,
but this morning both were down, and showed:

[***@node-01 ~]# drbd-overview
0:drbd0 StandAlone Secondary/Unknown Inconsistent/Outdated r-----
1:drbd1 Connected Secondary/Secondary UpToDate/UpToDate C
r-----

[***@node-02 ~]# drbd-overview
0:drbd0 WFConnection Secondary/Unknown Inconsistent/DUnknown C r-----
1:drbd1 Connected Secondary/Secondary UpToDate/UpToDate C r-----

We had a power failure two weeks ago, but nothing seemed wrong.

How do I recover from this situation? How can I find out which of the nodes
has
the most recent information? And then mark it UpToDate?

Thanks,
Ron

Tail the system logs on both nodes, then on node 1, run 'drbdadm connect
r0'. Wait for things to settle, then share the new status of /proc/drbd
and the log output from the two nodes please.
