Hi All, I think I have stumbled on a bug. I'm running Infernalis (Kernel 4.4 on the client) and it seems that if the RBD header object gets evicted from the cache pool then you can no longer map it. Steps to reproduce rbd -p cache1 create Test --size=10G rbd - p cache1 map Test /dev/rbd1 <-Works!! rbd unmap /dev/rbd1 rados -p cache1 cache-flush rbd_id.Test rados -p cache1 cache-evict rbd_id.Test rbd - p cache1 map Test rbd: sysfs write failed rbd: map failed: (95) Operation not supported or with the rbd-nbd client 2016-01-27 13:39:52.686770 7f9e54162b00 -1 asok(0x561837b88360) AdminSocketConfigObs::init: failed: AdminSocket::bind_and_listen: failed to bind the UNIX domain socket to '/var/run/ceph/ceph-client.admin.asok': (17) File exists 2016-01-27 13:39:52.703987 7f9e32ffd700 -1 librbd::image::OpenRequest: failed to retrieve image id: (95) Operation not supported rbd-nbd: failed to map, status: (95) Operation not supported 2016-01-27 13:39:52.704138 7f9e327fc700 -1 librbd::ImageState: failed to open image: (95) Operation not supported Nick _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
