Dear all<br>
<br>
Last week I posted a query about a problem I had with a machine that had failed but the underlying hard disk with the gluster brick was good. I’ve made some progress in restoring. I now have the problem with my new restored machine where it becomes its own peer, which then breaks everything.<br>
<br>
1. Gluster daemons are off on all peers, content of /var/lib/glusterd/peers looks good.<br>
2. I start the gluster daemons on all peers. All looks good.<br>
3. For about 2 minutes, there’s no obvious problem — if I do a gluster peer status on any machine it looks good, if I do a gluster volume status A01 on any machine it looks good.<br>
4. Then at some point, the /var/lib/glusterd/peers file of the new, restored machine gets an entry for itself and things start breaking. A typical error message is the understandable<br>
<br>
: Unable to get lock for uuid: 4fb930f7-554e-462a-9204-<wbr>4592591feeb8, lock held by: 4fb930f7-554e-462a-9204-<wbr>4592591feeb8<br>
<br>
5. This is repeatable — if I stop daemons, remove the offending entry in /var/lib/glusterd/peer, and restart, the same behavior occurs — all good for a minute or two and then something magically puts something in /var/lib/glusterd/peers<br></blockquote><div><br></div><div>I'd need few more details here:<br><br></div><div>1. output of gluster peer status<br></div><div>2. output of cat /var/lib/glusterd/<a href="http://glusterd.info">glusterd.info</a> & cat /var/lib/glusterd/peers/* from all the nodes<br><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

In a previous step in restoring my machine, I had a different error of mismatching cksums and what I did then may be the cause of the problem. In searching the list archives I found someone with a similar cksum problem, and the proposed solution was to copy the /var/lib/glusterd/vols/ from another of the peers to the new machine. This may not be the issue but this is the only thing I think I did that was unconventional.<br>
<br>
I am running version 3.7.5-19 on Scientific Linux 6.8<br>
<br>
If anyone can suggest a way forward I would be grateful<br>
<br>
Many thanks<br>
<br>
Scott<br>
