You’re using a file system on 2 hosts that is not cluster aware. Metadata written on hosta is not sent to hostb in this case. You may be interested in looking at cephfs for this use case.

#node1
mount /dev/rbd/rbd/test /mnt
cd /mnt
touch test1
ls (i see test1, OK)
#node2
mount /dev/rbd/rbd/test /mnt
cd /mnt
(i see test1, OK)
touch test2
ls (i see test2, OK)
#node1
ls (i see test1, BAD)
touch test3
ls (i see test1, test3 BAD)
#node2
ls (i see test1, test2 BAD)
Why data not replicating on mounting fs ?
I try with filesystems ext4 and xfs
The data is visible only when unmounted and mounted again
I check health in "ceph status" and is HEALTH_OK
What I doing wrong ?
Thanks for any help.
