The one thing that still remains a mystery to me is how to downgrade
glusterfs packages in Ubuntu. I have never been able to do that. There
was also a post from someone about it recently on the list and I do
not think it got any replies.
I would have assumed something like:
1. stop volume(s)
2. if needed: reset gluster options not available is older version
3. if needed: downgrade op-version
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 glusterd.info file in all the nodes and then proceed to step 5.
4. stop all gluster daemons :)
5. sudo apt-get purge gluster*
6. sudo ppa-purge <gluster ppa>
7. Install older ppa.
8. install older gluster service
9. Start services
10. check peers and status
11. start volume
12. test
if 2) and 3) can't be done then I presume you can't downgrade.
