And sometime between 4:30am (or so) and 8:00am, something else must have happened because we have received emails and calls from a couple customers of problems with their virtual machines. Not a single message in the logs on the NAS about any error, warning, or critical issue occuring. All logs are clean with normal notices of informational standing (heartbeats being received, connections for SNMP, etc). The VMware logs tell a different story and show that at 5:48am there was a problem, with recovery at 6:04am. There are only ~15 VMs left on this volume and I'll be moving them during the business day today. I have some new, temporary, storage ready to get mounted up. We are (Doug and I) going to get everyone off of the storage completely (and onto the storage mentioned above) so we can take the hardware apart and try to figure out what is going on. This has to be a hardware issue, the problem follows the volume, the server operating system continues to run, is responsive. All VMs will be removed from this storage cluster so we can start to tear into the hardware ASAP. First priority is to remove all VMs from volume01 onto other storage. This is in process. Second priority is to remove all VMs from volume02 onto other storage. This will occur as the day progresses. We have a few pieces of storage already online. Approximately 1/2 of it is clustered storage and will be utilized immediately (it was the NetApp gear we were using before this new storage cluster was brought online in May, 2010 and is still quite serviceable). The other 1/2 are servers were we have swapped out the normal hard disk drives for larger ones, installed a server OS to handle NFS NAS duties, but these systems are *not* clusterable and will only be used for a very short period of time while we work out the issues with our production NAS.
