8:54 p.m.
Hello the list,
I have been slowly bringing up a 9-node cluster for the last few months.
All nodes are identical, dual 2-port 10G nics, lots of memory and CPU
Storage is a Netapp Filer accessed via NFS on a dedicated 10Gb
dual-switch environment.
Generally everything is working fine, but ever since our last rebuild of
the cluster in preperation for a move into production status we have
been getting repeated errors showing in the HostedEngine console:
VM foo is not responding.
VM bar is not responding.
VM baz is not responding.
These errors happen on a fairly regular basis, and generally are
multiple VMs all being hosted by different nodes. When errors occur I
also lose external connectivity to the VM in question, both via its
service IP address and via the ovirt console. The actual outages appear
to generally last 15-20 seconds and then things recover and go back to
normal.
We are also getting much more frequent errors:
ETL service sampling has encountered an error. Please consult the
service log for more details.
I have attached snippets from the Engine engine.log from this morning.
If any other logs are needed for to help diagnosis I can provide them.

Some more information, was doing more digging, and found that there is a
possible correlation between the VM timeouts and the following sanlock
messages:

This is from one of my nodes, and other not responding events match
other sanlock renewal errors very closely, with the sanlock errors
preceding the VM errors by a small amount. The other nodes have
virtually identical logs.
