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

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.

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.

The issue is the PPA does not change and the moment a new version is
released (even minor versions), the old packages are lost forever. Even if
you go to the PPA itself, the binaries seem to be deleted there.

apt-chache showpkg glusterfs only shows the latest version available, none
of the older ones are displayed so that you can then downgrade.

I am not sure if there is another way of doing this, but I have never
managed to successfully find and install the older releases without
manually obtaining the .deb files if I can find them.
