Description Ohad Basan 2013-08-21 07:42:00 EDT
Description of problem:

I have an iscsi dc with one active storage domain and two active hosts
I am trying to live 
migrate the vm from one host to another and I am receiving a message
cParams:{'path': ''} truesize:0 type:disk volExtensionChunk:1024 watermarkLimit:536870912

    raise KeyError(key)

one of the host was previously connected to an nfs dc with an nfs storage
so maybe something is not cleaned up properly.

Sergey, aren't you handling a similar issue already?

> Sergey, aren't you handling a similar issue already?

The exception in teardownImage seems to be log issue only, since it caught and handled.

According to that bug description, the issue was happen on 21/08 in 14:40, but attached vdsm logs contain information till 21/08 14:32.
Ohad, can you attach the rest of the log, please?

I've tested virsh connection from nari12 to nari13 yesterday and it seems to be working ok, do you still see the migration issue?
Comment 13 Ohad Basan 2013-09-10 07:46:49 EDT
I don't see that anymore...
Comment 14 Michal Skrivanek 2013-09-13 04:53:42 EDT
most likely an intermittent connectivity issue or firewall settings
