Hi,

i try to set up the object-based layout with pnfs.
I am using the OSC-OSD as target. It works well and i can login.
Trying the scripts "do-*" from git://git.open-osd.org/open-osd.git the do-osd script works for me. The do-exofs doesnt, here i have some question:

1. Is the UUID in the do-exofs script optional?

2. If no how can i get it for my device?

3. It is mandatory to use raid-driver (raid456) in the script? Why?


The error is: 
mount -t exofs -o osdname=d2683732-c906-4ee1-9dbd-c10c27bb40df,pid=0x10000,_netdev /dev/osd0 /mnt/osd0/
mount: wrong fs type, bad option, bad superblock on /dev/osd0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

dmesg says:
exofs: Unable to mount exofs on (null) pid=0x0 err=-22


Thanks for answering my questions.


Regards

Johannes
