Re: OpenSSI not loading up all of the fstab on boot

Hello John,

I have been looking into the fstab issue and I think that the reason that the main node fstab is not mounting the node swaps and local drives is simply because at the point of booting the main node, the other nodes are not yet booted and thus the main node cannot find the swaps and node drives to mount.

With this in mind, I was thinking that there must be an init script that each node it running to boot and I could add in:

> swapon
> mount /dev/sda2 /mnt/node02 

For each node to be one of the last things that the node does when it comes online. 

Actually you mentioned " Mounting things on nodes that boot up should be done in /etc/rcSSI.d/S35mountall.sh"

I am not sure how I should place my additions above, but I think that inside each /cluster/nodeX there could be a mount point for the local drive that the script could run.

What do you think?

Then, my next goal is to get an OpenSSI kernel that will allow me to utilize a UnionFS so that I can union all of the mounts from each node. The idea from there is to have an external drive on the main node that will backup the SCSI unioned node drives as a single filespace. This way I always have a backup of the date that is on the cheetah SCSI node drives in case a node fails.

Thanks and have a great day,
