Alright. On Tuesday I got an email from my NAS that I had a drive failure. NBD, I had a spare ready to be installed. During it's rebuild process (of the RAID 5 array) the NAS locked up and had to be rebooted. Since then the array has not been able to rebuild itself. I've since installed drives into my ESXi host server, and have a couple of VM's built up again (especially my AD DC). I was also [finally] able to connect my workstation up to the shares on the NAS (non-iSCSI volumes) and back up the files there. I can get the host to see the LUNs on the NAS, but I cannot actually connect to them to try to pull the VM's off. I have a couple of VM's I'd really like to retrieve, if it's possible. Mostly my digital image gallery server and my AD DC (previous version).
I figured I'd post up to see IF there's any hope (at all) in getting my VM's from the iSCSI LUNs over to either a backup drive (on my workstation) or onto one of the datastores in my host server. I didn't want to rebuild the array (will have to delete the configuration first) until I checked here. I plan on going from RAID 5 to RAID 6 when I rebuild it (5 drives in the array). IF I had an even number of drives, I'd be going to RAID 10 (next NAS/SAN).
I've attached a screen shot of the storage configuration screen for reference. When I try to 'mount' the volumes, I get an error message. Obviously, the host can SEE the LUNs, but cannot actually access them. If there's a doc out there with information on working through the issue, send me the link to it. I've also attached a screen shot of what I see in the NAS 'Storage Manager' screen.
BTW, I know this is a ghetto storage system. I'm between jobs, so I cannot afford to get a good/decent array to use instead. It is high on the priority list, once I'm working again. Looking to get something with at least 8 drives, and supports arrays that are very resilient. Also plan on getting all SAS drives, storage class, so that I really don't need to worry about this. Of course, I'll also have at least one drive still in the wrapper just in case I do get a failure.
