Hi there,
were still in deep sh** with heartbeat and drbd in a split brain
szenario.
We have the following set up:
- A two node active/passive cluster (heartbeat 2.1.3 without crm)
- Dopd with drbd-peer-outdater (the newest ones, patched).
- Ipfail
Still, if we disconnect one host from the network, both nodes become
primary. However we see a different behavior, if the primary or the
secondary get's disconnected:
- If we disconnect the primary (conetapp01 in our case) from the
network, the hosts stay in "WFConnection", and reconnect after the
primary's interfaces on the switch are up again. No sync happens, thus
changes made on the conetapp02 (which was temporarily primary during the
split brain) get lost.
- If we disconnect the secondary from the network, the host run in to a
"Standalone" situation. They stay there even after the secondary has
been attached to the network again and have to be connected manually by
"drbdadm connect all".
Dopd seems to be of no obvious use here: Both nodes outdate their peer.
What I like to see happening, is that the unattached peer outdates
itself! Isn't that the intended behavior?
An other thing that annoys me quite a lot, ist that heartbeat (well,
ipfail) notices that a disconnected host is dead. Still heartbeat
triggers a failover!
If anyone has a working configuration, or any suggestions how we can get
ours working or any other suggestions (even if it involves money for,
let's say, a stonith device) please let me know.
Attached you find the messages file from conetapp01 (our active primary)
and from conetapp02 (our standby secondary) and further down the
heartbeat and drbd configuration. We disconnected conetapp01 from the
network.
Thanks for your help!
