This looks similar to http://tracker.newdream.net/issues/2261. What do
you think Alex?
Not sure about that, since this crashes only the clients and not the
OSDs. We see no crashes in the cluster.
These are both rbd kernel client crashes, but looking again they seem
like different underlying issues, so I opened
http://tracker.newdream.net/issues/2287 to track this problem.
I analyzed it a bit more and found that the last working version was
0.43. Any later released version leads to this crash sooner or later,
but as I already said only on a 10Gbit (FC) network. I didn't see any
crash on the 1Gbit net on the same machines.
What kind of network do you use at dreamhost for testing?
Mostly 1Gbit, some 10Gbit, but I don't think we've tested the kernel
client on 10Gbit yet.
If you need more info, let me known.
Do the crashes always have the same stack trace? When you say 10Gbit
for the cluster, does that include the client using rbd, or just the
osds?
