<br>
it would help to see the results of the following commands:<br>
<br>
gluster volume info <volname><br>
gluster volume status <volname><br>
<br>
It would also be interesting to see fragments of the logs containing Warnings or Errors generated while the 'ls' command was executing (if any). The logs from the mount point are normally located at /var/log/glusterfs/<mount point>.log. Logs from the bricks are at /var/log/glusterfs/bricks/<<u></u>brick name>.log.<br>
<br>
Also, identify a file (I'll call it <file>, and its parent directory <parent>) that does not appear in an 'ls' from the mount point. Then execute the following command on all bricks:<br>
<br>
getfattr -m. -e hex -d <brick root>/<parent><br>
<br>
On all bricks that contain the file, execute the following command:<br>
<br>
getfattr -m. -e hex -d <brick root>/<parent>/<file><br>
<br>
This information might help to see what is happening.<br>
<br>

Dear all,<br>
Thanks again for your support.<br>
Files are already and exactly duplicated (diff confirms it) on the<br>
bricks, so I'd like not to mess with them directly (in order to not do<br>
anything worse to the volume than what it's already suffering).<br>
I found out, thanks to your help, that in order to trigger the<br>
self-healing there's no more the request of doing a find on all the<br>
files, but that there's the<br>
<br>
gluster volume heal VOLNAME full<br>
<br>
command to run. So I did a it and it said "Launching Heal operation on<br>
volume data has been successful. Use heal info commands to check<br>
status". But then asking for<br>
<br>
gluster volume heal VOLNAME info<br>
<br>
it reported each and every entry at zero, like "gluster volume heal<br>
VOLNAME info heal-failed" and "gluster volume heal VOLNAME info<br>
split-brain". It should be a positive news, or no?<br>
If I requested a "gluster volume heal VOLNAME info healed", on the<br>
other hand, revealed 1023 files per couple of bricks that got healed<br>
(very strange that the number is always the same. Is it an upper<br>
bound?). For sure all of them are missing from the volume itself (not<br>
sure if just 1023 per couple are missing from the total, maybe more).<br>
I thought that now at least those should have become visible, but in<br>
fact those are not. How to check logs for this healing process? Doing<br>
a "ls -ltr /var/log/glusterfs/" says that no logs are being touched,<br>
and even looking at the most recent ones reveals that just healing<br>
command launch is reported into them.<br>
I rebooted the nodes but still nothing changed, files are still<br>
missing from the FUSE mount point but not from bricks. I relaunched<br>
the healing and again, 1023 files per couple of bricks got<br>
self-healed. But still, I think that they are the same as before and<br>
those are still missing from the fuse mount point (just tried a few<br>
reported by the gluster volume heal VOLNAME info healed).<br>
<br>
Do you have any other suggestion? Things are looking very bad for me<br>
now because of the time that I'm forcing others to loose (as I said,<br>
we don't have any system administrator and I do it just "for fun", but<br>
still people look at you as the main responsible)...<br>
<br>
Best regards,<br>
<br>
Stefano<br></div></div><div class="im">
