rbd map image with journaling
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, -- Herbert

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

You could use rbd-nbd # rbd-nbd map image@snap -- Alexander E. Patrakov CV: http://pc.cd/PLz7

Thanks. 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. -- Herbert
