<p>It should be possible.</p>
<p>You will need to update the config (writeconf) to reflect the IP
of the host (failnode or servicenode).<br>
This way, when it reports to the MGS, it is known and will be
accepted into the mix :)</p>

<div>Hi everyone,<br>
</div>
One of our OSS nodes failed to come back up after a
firmware upgrade.<br>
</div>
I'd like to mount its' OSTs on one or more of the other
OSSs to allow the filesystem to remain available.<br>
</div>
Is this possible?<br>
</div>
Thanks,<br>
</div>
