Lighting has struck twice...
Oddly enough it was a storm that took out my power, causing my Dell PowerVault 220s Array to fail yet again. I spent a couple of days trying to remount the NFS volume served up by OpenFiler that the PowerVault hosted.
VMWare timed out every time I attempted to mount the NFS volume...Even after a fresh build of OpenFiler, a Initialize and reconfig of the RAID5 array used for the NFS volume and a rebuild of the XFS volume inside of OpenFiler.
I was able to connect via SMB, and the data (VMs) were there. I decided to utilize a fun little tool I use at work called Veem FastSCP, allowing me to initiate a transfer from one OpenFiler server to another (as well as tranfers between ESX hosts, Linux systems and Virtual Center servers).
My speeds were decent going from one OpenFiler box to the other prior to my removal of the RAID5 volume and recreationg (starting at the RAID card level and working my way thru a new OpenFiler build)
I eventually gave up trying to get VMWare to connect to the server in question via NFS again. It had at one point, until the array behind it all took a turn for the worse... Yet again I still was able to mount the volume in Windows via SMB and access the data...
Once everything was dumped over to OpenFiler box #2, I pointed ESX at that system and was able to load up NFS and mount the VMs (ruling out an issue with the ESX server).
In the end (as of the moment of writing this article) I ended up falling back to iSCSI to get the enviroment back online.
I've kept a copy of all the VM servers on SATA, residing on OpenFiler box #2.. Hopefully providing a fast DR until I get a better backup solution and more batteries in the rack!
