of course, original software is totally useless !!!!
That's way I spent a lot of time doing that job !!!!!

No, it is on a 1.8 TB stripe set
/dev/sda1 9.7G 1.2G 8.0G 13% /
tmpfs 252M 0 252M 0% /lib/init/rw
udev 10M 100K 10M 1% /dev
tmpfs 252M 4.0K 252M 1% /dev/shm
/dev/md0 1.8T 1.5T 243G 86% /storage
/dev/sde1 299G 299G 0 100% /mnt/usbdisk

no, I Don't; it is:
/storage *(rw,no_subtree_check,sync,no_root_squash)

I don't use ftp.
I am using rsync "internally", to sync the /dev/sda1 with
/dev/sdb1
/dev/sdc1
/dev/sdd1
actually I have root on sda1 sync-ed with corresponding partitions on b,c and d
swap on sda2
then I have linux raid 0 on th 4 remaining partitions (sda3, sdb2, sdc2, sdd2)
Internal cp command from one partition to the other doesn't pass 10 MB/sec

I had to cut a standard cable and reconnect the pin in the rigth order.

Yes, I did

It wasn't so difficout; I have that hole in the top of the NAS, with the serial
internal flat cable going down till the onboard connector. The cable has to be
the right length, in order to let you open and close the NAS without too much problems...
I used a very old external serial board.
