problem while removing images

[Thiago Gonzaga <thiago.gonzaga@xxxxxxxxx>]

Hey Guys,

Is it normal to get all process stuck while a image is deleting?

I'm removing 21g layering image and it takes ages, while the image is removing I have lots of problems in the log like this

I ran rbd create rbd/test -s 21G --image-feature layering

deleted the image while deleted that tried to create another one and format it

root@ceph-mon-3:/home/tgonzaga# rbd create rbd/test2 -s 10G --image-feature layering

root@ceph-mon-3:/home/tgonzaga# rbd map test2

/dev/rbd0

it's stuck until the image gets completely deleted

And I can't perform anything on other images.

Any ideas?
