Hi,
I've a 2 node active/passive cluster ( active node=>active , passive
node=>standby) using heartbeat 2.0.8 . I recently enabled stonith .
The
stonith device is an rsh device that tries to restart the cluster
node.
However, something that used to work with stonith disabled has stopped
working now ; Node failover on network cable disconnection. I believe
since the stonith device uses the network, the stonith fails and hence
the resource is left wherever it was running.
correct. the cluster will not start anything until it can verify the
node is truly dead (with a successful stonith operation)
this is how a stonith enabled cluster is supposed to work and is why
IP-based stonith modules are not a great idea.
Can anyone please help resolve this problem (this is probably not a
problem and this is how stonith is expected to work )? I would like to
know if there's anyway to tell the passive (currently active node) to
give up trying to stonith and then start the resource.
by design - no.
I've attached my
cib file and logs from the passive when cable is disconnected.
I've no problem both nodes running the resource as active is anyway
cut-off from network and can't do any damage.
if thats truly the case, then you may not need stonith.
The standby log seems to
say it has quorum
2-node clusters always have quorum, so the value is meaningless...
but it makes me wonder why it doesnt start the
resources , inspite of the following evident from the logs.
1. Standby marks active unclean
2. Standby has quorum
3. Standby tries to move resources back to standby
Thanks in advance,
Abhi.
