Because we are using debian, we are following the procedure in <a href="http://wiki.debian.org/Lustre">http://wiki.debian.org/Lustre</a> and using the current version of luster 2.2, Debian Linux ported to <a href="http://pkg-lustre.alioth.debian.org">http://pkg-lustre.alioth.debian.org</a></div><div><br></div></div><div><div><div>From what I've observed, the problem seems to be the creation of the filesystem "MGS" and then mount.</div><div>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:</div><div><br></div><div>$ 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</div><div><br></div><div>After creating the system successfully, the next problem comes when committing mount the new filesystem:</div><div><br></div><div>$ mount -t luster /dev/sdc1 /mgs</div><div><br></div><div>It seems that the whole problem is loading the kernel module fsfilt_ldsikfs, which is dependent of "ldiskfs":</div><div><br></div><div>$ modprobe fsfilt_ldiskfs</div><div>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)</div><div><br></div><div>Running "dmesg", we note the following:</div><div><br></div><div>$ dmesg</div><div>...</div><div>[81314.051179] fsfilt_ldiskfs: Unknown symbol jbd2_log_start_commit</div><div><br></div><div>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 …</div></div><div><br></div><div>Any idea if someone has managed to create the appropriate patch???</div><div><br></div><div>thanks</div><div apple-content-edited="true">
