It could be a "simple" bug - software has bugs and regressions.
I would recommend you to ping the debian mailing list - at least it won't hurt.

Well... It seems to me that pure Debian Linux 10 has some problem with XFS, which is the FS that I used.
It's not accept attr2 mount options.
Interestingly enough, I have now used Proxmox 6.x, which is Debian based, I am now able to use the attr2 mount point option.
Then the Faulty status of geo-rep has gone.
Perhaps Proxmox staff has compiled xfs from scratch... Don't know....
But now I am happy ' cause the main reason to use geo-rep to me is to use it over Proxmox....
cat /etc/fstab # <file system> <mount point> <type> <options> <dump> <pass> /dev/pve/root / xfs defaults 0 1 /dev/pve/swap none swap sw 0 0 /dev/sdb1 /DATA xfs attr2 0 0 gluster01:VMS /vms glusterfs defaults,_netdev,x-systemd.automount,backupvolfile-server=gluster02 0 0 proc /proc proc defaults 0 0
