Hi All, I'm starting with ceph and faced a problem while using object-map
root@ceph-mon-1:/home/tgonzaga# rbd create test -s 1024 --image-format 2 --image-feature exclusive-lock root@ceph-mon-1:/home/tgonzaga# rbd feature enable test object-map root@ceph-mon-1:/home/tgonzaga# rbd list test root@ceph-mon-1:/home/tgonzaga# rbd map test rbd: sysfs write failed RBD image feature set mismatch. You can disable features unsupported by the kernel with "rbd feature disable test object-map". In some cases useful info is found in syslog - try "dmesg | tail". rbd: map failed: (6) No such device or address how can we deal with that? I see some comments that large images without omap may suffer to get deleted Regards, *Thiago Gonzaga*
