<strong>2. Delete the corrupted files</strong>
":</div><div>In my experience there are two GFID files if a copy gets corrupted. Example:</div><div><i>$ find /gluster/brick1/glusterbrick/.glusterfs -name fc36e347-53c7-4a0a-8150-c070143d3b34<br>/gluster/brick1/glusterbrick/.glusterfs/quarantine/fc36e347-53c7-4a0a-8150-c070143d3b34<br>/gluster/brick1/glusterbrick/.glusterfs/fc/36/fc36e347-53c7-4a0a-8150-c070143d3b34<br></i></div><div><i><br></i></div><div><i></i></div><div>Both GFID files has to be deleted. If a copy is NOT corrupted, there seems to be no GFID file in <br></div><div><i>.glusterfs/quarantine . </i>Even one executes scub ondemand, the file is not there.
The file in
<i>.glusterfs/quarantine</i> occurs if one executes "scrub status".</div><div><br></div><div>

<strong>3. Restore the file</strong>
":</div><div>One alternatively trigger self heal manually with</div><div><i>gluster vo heal VOLNAME</i></div><div>But in my experience this is not working. One have to trigger a full heal:</div><div>
<i>gluster vo heal VOLNAME</i> <i>full</i></div><div><i><br></i></div><div>Imagine, one will restore a copy with manual self heal. It is neccesary to set some VOLUME options (stat-prefetch, dht.force-readdirp and performance.force-readdirp disabled) and mount via FUSE with some special parameters to heal the file?</div><div>In my experience I do only a full heal after deleting the bad copy and the GFID files.</div><div>This seems to be working. Or it is dangerous?</div><div><br></div><div>Regards</div><div>David Spisla<br></div><div><i></i></div><div><i></i></div><div><i></i><br></div><div><br></div><div><br></div></div></div></div></div></div>
