Uhm, you might try "mount -o remount,rw,<otheroptions> /mountpoint" or you may have to unmount it using "umount" (possibly with the "-f" flag) and either manually remount or trigger the automount. From the nfs(5) man page: With few exceptions, NFS-specific options are not able to be modified during a remount. The underlying transport or NFS version cannot be changed by a remount, for example. I suspect the timeouts fall into those "NFS-specific" bits. With those caveats, give it a go. IIRC, the mount options in /etc/fstab are only used at the time of mounting. Changes to fstab won't take effect without a remount of some sort. The best remount is a full umount/mount cycle, but umounting (without the "-f") will require that there are no open files on that filesystem. Using the "-f" will forcefully dismount it and that can lead to some grievous consequences to processes actively using the filesystem at the time of the dismount.
