Hello Thomas,
<div><br>
</div>
<div>
<div>For several weeks new, I'm trying to install luster 2.2 on debian squeeze server. From what I've observed, the problem seems to be the creation of the files system "mgs/mdt" and then mount.</div>
<div>The error message about the file /etc/mke2fs.conf, seems like a "warning". To avoid this, vast with adding a new line in the file, like this:</div>
<div><br>
</div>
<div>
<div><span class="Apple-tab-span" style="white-space: pre; "></span>ldiskfs = {</div>
<div><span class="Apple-tab-span" style="white-space: pre; "></span> blocksize = 4096</div>
<div><span class="Apple-tab-span" style="white-space: pre; "></span>}</div>
</div>
<div><br>
</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>
