The one thing that still remains a mystery to me is how to downgrade<br>
glusterfs packages in Ubuntu. I have never been able to do that. There<br>
was also a post from someone about it recently on the list and I do<br>
not think it got any replies.<br>

I would have assumed something like:<br>
<br>
<br>
1. stop volume(s)<br>
<br>
2. if needed: reset gluster options not available is older version<br>
<br>
3. if needed: downgrade op-version<br></blockquote><div><br></div><div>Downgrading op-version is not possible until and unless changes are done from back end. So my suggestion is to swap the step 3 & step 4. We need to first stop all the gluster services, change the op-version in <a href="http://glusterd.info">glusterd.info</a> file in all the nodes and then proceed to step 5.<br> <br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
<br>
4. stop all gluster daemons :)<br>
<br>
5. sudo apt-get purge gluster*<br>
<br>
6. sudo ppa-purge <gluster ppa><br>
<br>
7. Install older ppa.<br>
<br>
8. install older gluster service<br>
<br>
9. Start services<br>
<br>
10. check peers and status<br>
<br>
11. start volume<br>
<br>
12. test<br>
<br>
<br>
if 2) and 3) can't be done then I presume you can't downgrade.<span class="HOEnZb"><font color="#888888"><br>
