Hi,
is there any way to do that without disabling journaling?
# rbd map image@snap
rbd: sysfs write failed
RBD image feature set mismatch. You can disable features unsupported
by the kernel with "rbd feature disable image@snap journaling".
In some cases useful info is found in syslog - try "dmesg | tail".
rbd: map failed: (6) No such device or address
# ceph -v
ceph version 12.2.13 (584a20eb0237c657dc0567da126be145106aa47e) luminous (stable)
# uname -r
5.4.52-050452-generic
Thanks,

Negative at this point. There are no versions of the Linux kernel that
support the journaling feature.

I did it, but sometimes it became stuck, that's why I sent another
email to the list asking about the rbd-nbd stuck requests problem.
