Had an upgrade to Ubuntu Gutsy Gibbon go badly. Now I'm digging out from under. Part of what was lost was my /etc directory getting scrambled so I couldn't read my old /etc/fstab entry. Been fighting to remember how things worked to mount my SimpleShare for backup and access to my ripped CDs. I finally found this article on Ubuntu Linux, SimpleShare NAS, and NFS which includes this key part:

mediaserver:/shares/SimplePool/Photos/ /mnt/photos nfs rsize=8192,wsize=8192,timeo=14,intr

It still didn't work for me, though. Was getting "can't read superblock" which was a little scary after not being able to boot due to Grub error 17 or the system just not coming up. Found the solution on LinuxQuestions try using the -o nolock option from the nfs mount command. So the command is now:

mediaserver:/shares/SimplePool/Photos/ /mnt/photos nfs rsize=8192,wsize=8192,timeo=14,intr,nolock

and everything seems to be working well. Well, with NFS, anyway.
