This also sounds like a possible GlusterFS use case. Regards, -Jamie On Tue, Jun 15, 2021 at 12:30 PM Burkhard Linke < Burkhard.Linke@computational.bio.uni-giessen.de> wrote:

Hi,
That's right!
We're currently evaluating a similar setup with two identical HW nodes (on two different sites), with OSD, MON and MDS each, and both nodes have CephFS mounted.
The goal is to build a minimal self-contained shared filesystem that remains online during planned updates and can somehow survive should disaster strike at one of the two sites.
This sounds like a use case for DRBD, maybe with OCFS2 on top as cluster(ed) filesystem. Ceph is overkill, and not really suited for two hosts setups.

Burkhard
