[Gluster-users] Ovirt and gluster 7/8

[Valerio Luccio]

Hello all,

I have a gluster storage that is still running gluster 5. Unfortunately 
I have some legacy systems that cannot be updated that use this storage 
(I'm hoping to replace these systems in the next 12 months, I do all of 
this by my lonesome so it takes some time).

On a CentOS 8 server I run Ovirt to manage some VM's. It was using 
gluster 7 to connect to the storage and that worked. A couple of days 
ago I did an update and Ovirt updated my gluster packages to 8, after 
which I now get 'Failed to get trusted.glusterfs.shard.file-size' when 
trying to create files from the Ovirt server (the other servers don't 
have issues). Two related questions:

 1. Is there a way to fix this, maybe changing some parameter in a conf
    file ?
 2. If 1. is not possible, can you see pitfalls in downgrading the
    packages to gluster 7 after downloading them from
    http://mirror.centos.org ?

Thanks in advance.
