For the size it's already more that what I have, most of our VMs are
20 Gb or less. They are almost all Linux webservers, the load on the disk
comes from MySQL almost exclusivly, but I guess load is load.
Still, it's not much, I think we currently have something like 15 Mb/s
average writing on the volume, so nothing crazy.

Did you add a third brick in replication, if I understand it correctly ?
That's not the problem I had, that does seem to be working fine.
What broke was adding 3 new bricks to a replica 3, bumping it from 1 x 3
to a 2 x 3. That doesn't start a heal, at least not until you start a
rebalance, but I didn't even get to that point :(

That's the only bug I've experienced so far in 3.7.12, everything else
(including increasing the replica count) seems to be working perfectly fine.
That's why I'm still installing that version, even though it's outdated.

Thanks !
