I should mention that this has been solved. The problem was a bad disk
in the Compellent's tier 2 storage. The mutlipath.conf and iscsi.conf

Is there maybe some IO problem
Is there maybe some IO problem on the iSCSI target side?
IIUIC the problem is some timeout, which could indicate that the target
is overloaded.
Maybe. I need to check with Dell. I did manage to get it to be a little
more stable with this config.

Hi Chris,
I have an Ovirt + Dell Compellent similar to yours (previous model, not
SC8000) and sometimes I faced issues similar to yours.
From my experience I can advise you to
A) check links between SAN and servers, all paths, all configuration,
cabling. Everything should be setup correctly (all
