Hi Daniel,<br>
<br>
Ok, if gluster can't self-heal from this situation, I hope at least I can manually restore the volume by using the good brick available. So would you please tell me how can I "simply rebuild the filesystem and let gluster attempt to restore it from a *clean* filesystem"?<br>

You could do as Tom Pfaff suggests, but given the odds of data corruption carrying forward I'd do the following:<br>
Shut down gluster on the damaged system.<br>
Unmount the damaged filesystem.<br>
Reformat the damaged filesystem as new (throwing away any potential corruption that might not get caught on rebuild)<br>
Mount the new filesystem at the original mount point<br>
Restart gluster<br>
<br>
In the event of corruption due to hardware failure you'd be doing this on replacement hardware.<br>
The key is you have to have a functional filesystem for gluster to work with.<div class="HOEnZb"><div class="h5"><br>
