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 really couldn't find any references about sync status in docs. When I tried to remove the image from primary node, I caught following error:
# rbd --cluster server-31 rm int32bit-test/mirror-test
2017-01-24 12:40:41.494963 7fd8dff91d80 -1 librbd: image has watchers - not removing
Removing image: 0% complete...failed.
rbd: error: image still has watchers
This means the image is still open or the client using it crashed. Try again after closing/unmapping it or waiting 30s for the crashed client to timeout.
I wonder know if my mirror status is ok and how to remove mirrored image.
My ceph version is 10.2.3, and the default rbd features is set to 125.
Thanks for any help!
