Description Haim 2012-01-30 10:58:52 UTC

spm logs.

Description of problem:

Flow: 

- 2 hosts, connected to iSCSI pool
- vm is running on HSM 
- start 'dd' on guest O.S to fill thinly provisioned disk
- HSM creates an extend messages, asking SPM to extend disk (lvextend) 
- SPM doesn't seem to check mailbox

from digging into host, it seems as if SPM_MailMonitor is not alive on SPM.

please note that I don't have consistent repro for this issue, though i'm a bit concern, so decided to open a bug, I would like you guys to go over the flow in the code, and see if there is a place where something like that can happen.
