Subject Re: NFS machine not responding, timed out issue
Date Thu, 13 Feb 2014 01:03:16 GMT
Hi Umar,
Did you verify your network per Shanker's suggestion?  You need to make
sure the NIC flapping is fixed first before you can expect anything to run
stably.  When you say you are able to mount it manually, did you also try
copying data over that mount?  I had a similar problem once and it ended up
being a bad cable.
Regards,
-Carlos

Your NIC link is flapping way too often and thats possibly whats causing
NFS to freak out. Try to narrow down the cause of the link flaps:

1) Force link speed settings
2) Change patch cords
3) Replace physical NIC
4) Try patching to another switch port
5) Check switch port speed settings
