I take it that using the same option in fstab will work as well? Just that
I applied this change last night and it made no difference at all :-(
zeus:/mnt/store /mnt/store nfs
rsize=8192,wsize=8192,hard,intr,nfsvers=3,actimeo=0 0 0
Since I'm running a nfs root file system (diskless combined be/fe), will
the attributes of the root filesystem (caching etc) propagate down through
the mount point or will the new mount attaching to a point within the root
filesystem override this.
Can't see a way of overriding the attributes of the root filesystem (can I
do a remount of a root nfs system?) from the network grub command line.
I'll experiment some more with this anyway.
Is there a simple way to find out what the current mount parameters are on
a running system? Be handy to see if the changes 'stick' !! I guess there
is something in the /proc filesystem. Hmmm - more playing...
