I have a situation with a server that uses storage on a QNAP NAS. The storage is shared using NFS. Apparently there was a problem with the NAS this afternoon which crashed the server. The server will no longer boot up because the NAS shared storage is showing as inaccessible. The NAS is up, however, and the storage shows as active on the NAS.
When I try to start the server, I get the following error:
Failed - File system specific implementation of GetFileAttributes[file] failed

Cannot open the disk '/vmfs/volumes/357487ab-0942b56e/VM-Estelle-BDR/VM-Estelle-BDR.vmdk' or one of the snapshot disks it depends on.
Module 'Disk' power on failed.
Failed to start the virtual machine.
On the VSphere Client console, the datastore shows as inaccessible.
I was thinking about dismounting the datastore and then trying to remount it. But I seem to remember some bad experiences in the past when dismounting would erase everything on the datastore. I think this was with an iSCSI connection but I want to be sure before I try it. So, is it safe to try the Unmount procedure with an NFS datastore and then try to remount it, or will I lose the data?
Any other suggestions for remedying this?
Thanks!
Deb
