[Gluster-users] Brick Goes Offline After server reboot.

[Jorick Astrego]

Hi,

It looks like you have a two node setup?

Then it's expected as with two nodes you don't have quorum and this can
lead to split brains.

To have HA, add another node or an arbiter node.

https://docs.gluster.org/en/latest/Administrator%20Guide/arbiter-volumes-and-quorum/

You can also modify the quorum but then you shouldn't be too attachted
to the data you have on it.

Regards, Jorick
