[ceph-users] [RBD][mirror]Can't remove mirrored image.

Hi,All, I'm a new comer of Ceph, I deployed two ceph cluster, and one of which is used as mirror cluster. When I created an image, I found that the primary image blocked in 'up+stopped' status and the non-primary image's status is 'up+syncing`. I'm really not sure if this is in OK status and I

Re: [ceph-users] Issue with upgrade from 0.94.9 to 10.2.5

i was just testing an upgrade of some monitors in a test cluster from hammer (0.94.7) to jewel (10.2.5). after upgrade each of the first two monitors, i stopped and restarted a single osd to cause changes in the maps. the same error messages showed up in ceph -w. i haven't dug into it much but

[ceph-users] machine hangs & soft lockups with 10.2.2 / kernel 4.4.0

Hi, We have a 9-node ceph cluster, running 10.2.2 and kernel 4.4.0 (Ubuntu Xenial). We're seeing both machines freezing (nothing in logs on the machine, which is entirely unresponsive to anything except the power button) and suffering soft lockups. Has anyone seen similar? Googling hasn't found
