I have switched to linbit repo, but I don't think that there are more
problems than with pve ones; in my configuration I still have some
issues (with qmrestore towards drbd storage, and automatic start of
resources at boot, mainly), but I can't say that these are new or
specific to linbit provided components.

See my former notes; in my experience I still have many doubts about
using DRBD9 with PVE in production, even if I have it running for
several months now. In particular I think that PVE DRBD9 storage
integration needs refinements (storage occupation still does not
correctly accounts for redundancy, and lacks features (such as volume

On DRBD9 side, I still note randomly out-of-sync on some resources after
node reboot, which I am able to fix only manually (disconnecting and
reconnecting after some time, and similar ...)

I recommend to upgrade to 4.4, firstly. In any case, given that Proxmox
will not provide further support for DRBD9 in PVE, you should consider
the switch to linbit repo in any case, if you want to keep using it in
the future.
