I'm working on upgrading a set of our gluster machines from 3.7 to 3.10-
at first I was going to follow the guide here:
https://gluster.readthedocs.io/en/latest/Upgrade-Guide/upgrade_to_3.10/
but it mentions:
* Online upgrade is only possible with replicated and distributed
replicate volumes
* Online upgrade is not supported for dispersed or distributed
dispersed volumes
and
*ALERT*: If any of your volumes, in the trusted storage pool that is
being upgraded, uses disperse or is a pure distributed volume, this
procedure is *NOT* recommended, use the Offline upgrade procedure
<https://gluster.readthedocs.io/en/latest/Upgrade-Guide/upgrade_to_3.10/#offline-upgrade-procedure>
instead.
The data stored on this gluster volume (Distributed-Disperse, 2 x (4 +
2) = 12) is somewhat critical, but I wanted to make sure there was no
possible way to do an 'online' upgrade before following the 'offline'
steps.
