Hi all

Following picture shows my setup [image: image.png]

I m facing following error when i issue a command to enable rbd mirroring on a particular image either manually or through cinder.

*"rbd::mirror::InstanceWatcher: C_NotifyInstanceRequest: 0x7fb364025310 finish: resending after timeout"* in rbd-mirroring.log

and getting *"failed to get omap key: client_0921b3ce-716a-4462-b3cf-86b5102bfd9"* error in osd.log.

. Should I enable anything else apart from timeout parametes, if the distance between the two ceph clusters is greater than 300km?

when I create a bootable volume of 100 GB with a glance image.Image get downloaded and from cinder, volume log throws with "volume is busy deleting volume that has snapshot" . Image was enabled with exclusive lock, journaling, layering, object-map, fast-diff and deep-flatten Cinder volume is in error state but the rbd image is created in primary but not in secondary.

pls check the logs

1)Log for manual rbd image creation
