the 'hard' means 'never give up' (you can use 'soft' here, but it's not a good idea, the server tends to time it out too quickly. you might want to look at timeo= to set this timeout up, but hard is probably wiser)
the 'intr' means 'allow signals to interrupt this process'. ie: if the process has 'hung' waiting on the nfs server, you can still kill it (if for instance you wanted to umount(8) the now broken nfs mount)

+!!NFS Hangs when the servers still there
+I was having issues with NFS locking up or producing IO errors when transfering large(ish) ammounts of data (10Meg or more) via NFS using pretty much defult options, changing the options to mount as follows cleared these problems up.

!!I exported stuff and NFS isn't allowing it to mount!
You probably forgot to run exportfs(8) after updating exports(5). Silly you.

!!Performance sucks!
Try adding the 'async' option to the export in /etc/exports. Also check your rsize/wsize, larger tends to be better (but does lead to fragmentation) If you have a gig clean path between two hosts, make sure they have 9k byte MTU's and that the r/w size is 8k.
