To add to the history of the issue.

The /dev/sdi1 which was mounted on the /apps went unmounted automatically so the user raised ticket.
But one of the admin to try to mount it ran the sync command first the tried to mount it with

# mount -o rw /dev/sdi1 /apps

I do not know if the error related to I/O like below, were because of the sync command and we could not mount the partition.

Buffer I/O error on device sdv, logical block 262143
end_request: I/O error, dev sdv, sector 0
Buffer I/O error on device sdv, logical block 0


Thanks Experts.

As you can see there is no devive "/dev/sdi1" on the system so you cannot mount it.

Something was not clear in your question, why using the -t NFS option ? is it because you want to mount the disk thru the network ? If it is the case as your system claim the syntax you provide is not good.

Give me more information about /dev/sdi1, it was suppose to be attached to the system or to anather system thru the network?

OK. This issue happened because one of the SAN device produced an hardware error. So that was the reason why it went unmount and became unavailable.
