Liron,can you please provide steps to reproduce
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 ('172.20.245.39', 50694) Traceback (most recent call last): File "/usr/lib64/python2.6/SocketServer.py", line 560, in process_request_thread File "/usr/lib64/python2.6/SocketServer.py", line 322, in finish_request File "/usr/lib64/python2.6/SocketServer.py", line 617, in __init__ File "/usr/lib64/python2.6/BaseHTTPServer.py", line 329, in handle File "/usr/lib64/python2.6/BaseHTTPServer.py", line 323, in handle_one_request File "/usr/lib64/python2.6/SimpleXMLRPCServer.py", line 490, in do_POST File "/usr/lib64/python2.6/BaseHTTPServer.py", line 384, in send_response File "/usr/lib64/python2.6/BaseHTTPServer.py", line 390, in send_header File "/usr/lib64/python2.6/socket.py", line 324, in write File "/usr/lib64/python2.6/socket.py", line 303, in flush File "/usr/lib64/python2.6/site-packages/M2Crypto/SSL/Connection.py", line 222, in write File "/usr/lib64/python2.6/site-packages/M2Crypto/SSL/Connection.py", line 205, in _write_bio which means that another engine(client ,IP='172.20.245.39') 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.
