Hi list,

For several weeks, I'm trying to create a simple outline of Lustre filesystem 
on Linux Debian squeeze. Because we are using debian, we are following the 
procedure in http://wiki.debian.org/Lustre and using the current version of 
luster 2.2, Debian Linux ported to http://pkg-lustre.alioth.debian.org

From what I've observed, the problem seems to be the creation of the filesystem 
"MGS" and then mount.
Initially, to create the file system "MGS/MDT," we must run mkfs.lustre 
avoiding default option "dirdata", which is not covered by the current version 
2.2:

$ mkfs.lustre --fsname=lustrefs --mdt --mgs --reformat --mkfsoptions="-E 
stripe-width = 2-i 4096-O ^ dirdata" --failnode=mdserver-1 
--mgsnode=mdserver-0@tcp0 /dev/sdc1

After creating the system successfully, the next problem comes when committing 
mount the new filesystem:

$ mount -t luster /dev/sdc1 /mgs

It seems that the whole problem is loading the kernel module fsfilt_ldsikfs, 
which is dependent of "ldiskfs":

$ modprobe fsfilt_ldiskfs
FATAL: Error inserting fsfilt_ldiskfs (/ 
lib/modules/2.6.32-lustre-2.2/updates/kernel/fs/lustre/fsfilt_ldiskfs.ko): 
Unknown symbol in module, or unknown parameter (see dmesg)

Running "dmesg", we note the following:

$ dmesg
...
[81314.051179] fsfilt_ldiskfs: Unknown symbol jbd2_log_start_commit

As we can see, there are a symbol required that is not implemented in the 
module. This is the key to the problem. I guess solving this, we get to create 
completely server Lustre MGS …

Any idea if someone has managed to create the appropriate patch???

thanks
