Comment 8 Liron Aravot 2014-08-10 06:06:55 EDT
Ori, take a look in https://bugzilla.redhat.com/show_bug.cgi?id=1024018#c1 ,
I'd start with that.

after reading very carefully comment #1, still don't understand what this bug is all about, clearly from the logs we can see:

Thread-106893::ERROR::2013-10-25 18:21:37,908::SecureXMLRPCServer::145::root::(handle_error) client ('', 50694)
Traceback (most recent call last):

which means that another engine(client ,IP='') is trying to connect to the same host, which explains why his vdsm keeps on falling.

I haven't used rhev 3.2 but it is very reasonable to assume that deleting block disk with post zeroing fails when you have other client that keeps on stealing your host and tells him to do other stuff.
