I'll look into this more to see what is happening.

This part works great and I set up /var/mntlocal also added it to my fstab.

Tried to do a "mount -a" after adding the info to the fstab, but still did not work and I had to mount them by hand with:

# onnode 2 mount /var/mntlocal /dev/sda2

For each node. Looks like I will have to add this command into a script that is run as the last step when the node boots up.

Now I am going to also start investigating "stackable" filesystems with OpenSSI like using FUSE for FiST, but think that it is going to require a kernel recompiled with the "CONFIG_FUSE_FS" kernel option set before I can load up (apt-get fuse-tools) and use them for a UnionFS across the mounted nodes.

I think that this will be a big problem and challenge to re-compile and upgrade my current OpenSSI 2.6.14-ssi-686-smp kernel though.

Thanks and have a great day,
