We are trying to unmap an rbd image form a host for deletion and hitting the following error:
rbd: sysfs write failed rbd: unmap failed: (16) Device or resource busy We used commands like "lsof" and "fuser" but nothing is reported to use the device. Also checked for watcher with "rados -p pool listwatchers image.rbd" but there aren't any listed. By investigating `/sys/kernel/debug/ceph/<cluster-id>/osdc` we get: 160460241 osd150 19.b2af34 image.rbd 231954'1271503593144320 watch Our goal is to unmap the image for deletion so if the unmap process should destroy the image is for us OK. Any help/suggestions? Best, Martin _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
