Subject Re: SR_BACKEND_FAILURE_61File SR creation error [opterr=fail to mount FileSR. Errno is 32]
Date Sat, 21 Nov 2015 03:03:46 GMT
Thanks Jayapal, Abhinandan.  

log SMlog doesnt giveout much, I am able to mount and edit file on mount from both server
and agent. I get the same error as follows (timestamp is different because I tried it again),
is there anything else I am missing?:

The error signifies that the creation of file storage repository failed on xenserver, check
that the nfs can be mounted and is writable.
The log file mentioned by Jayapal will give you further clues to the problem.
