Re: substitution of two faulty servers

[Erekle Magradze <erekle.magradze@xxxxxxxxxxxx>]

thanks for reply, but the problem is the number of replications, I have replication factor 3 so what would be the best way to substitute 2 bricks? as I understood properly first I need to add the server to gluster as a node, afterwards I need to add bricks to the volume (but if the number of bricks is not a factor of 3 it is not possible),

or, if there is other way please drop me a hint or link

Hello,

I have glusterfs 3.8.9, integrated with oVirt.

glusterfs is running on 6 servers, I have one brick from each server for
oVirt virtdata volume (used for VM images)

and 2 bricks from each servers (12 bricks in total) for data volume,
which is used as a file storage (with different sizes).

I would like to substitute 2 servers with new ones, due to the hardware
reorganization.

So for virtdata volume I need to substitute 2 bricks with the 2 bricks
from the new servers and for data volume I need to substitute 4 bricks
(2 bricks from each server) with 4 bricks from new servers.

In both volumes I have distributed replicated setup.

What would be the most recommended strategy for substitution operation?

Many thanks in advance.

Cheers

Erekle
