VM Keeps pausing

[sacrej]

Our fileserver VM 2008r2 on hyper-v with scvmm 2008r2 has as of about 30minutes ago just paused itself, we've not really been doing much on it, other that migrating user stores, the problem is, if you unpause it you get about a minutes usage before it pauses again.

info.
we have other VM's running, host servers are overspecced (dual x5650's (6cores per processor) and 32gb ram) host cpu usage is at about 5% and both have about 6-7gb of ram available - the only issue at the moment is that there is only one 1g link for each host server to the main domain network - they have a gig dedicated cluster link and each has 4 x 1gb to iscsi san using mpio.

what could be causing this?...nothing in event viewer

I have had this where there is not much space left on the host drive and it pauses fore safety, I'd check the avalible space on the drive holding the VHD.

ahhh....bingo.....colleague had increased the size of the VHD ffrom 100gb->200gb but hadnt checked the size of the host partition which was 100gb

doh...

migrated storage to a bigger host drive now....

problem solved

thank you
