Prometeus - Your 'net consultants !

Are expeeriencing OVZ style iowait, while there is no actual disk activity, probably because of the way the vswap works (slowed down memory to mimic real swap).
Since nothing seems to cure this issue once it started, we will take down the servers at midnight for a quick restart. Downtime will be short as these are fast and small ssd nodes.

pm29 did not come up after reboot, we are investigating the issue.

EDIT: PM29 is physically defective. We will try to restore it on another node.
Watch this space for news.

The new server will be ready tomorrow morning, we'll pull disks out of the broken servers and install to the new server.

New server in place, disks moved. PM29 is back :-)
