Since you deleted the stack this is meaningless. You can simply delete the volumes from pool using the rbd. The proper way to delete is to delete them before destroying the stack. If the stack is alive and you have issues deleting, you can take two approach. 1) run openstack volume delete with --debug to see what happens. 2) use rbd status pool/volume to see is there a watcher to the volume. If yes, then the instence has not been removed/not properly removed. Thanks, Suresh On Fri, Aug 16, 2019, 8:21 PM Nerurkar, Ruchir (Nokia - US/Mountain View) < ruchir.nerurkar@nokia.com> wrote:

Hello,

So I am able to install Ceph on CentOS 7.4 and I can successfully integrate my Openstack testbed with it.

However, I am facing with an issue recently where after deleting stack, my cinder volumes are not getting deleted and they are getting stuck.

Any idea on this issue?

Hello,

I work in Nokia as a Software QA engineer and I am trying to install Ceph on centOS 7.4 version.

Do you have to stick at 7.4?

But I am getting this error with the following output: -

Does anyone know about this issue like how can I resolve package dependencies?

My first shot: Update Centos to min. 7.5 (which includes gperftools-libs-2.6.1)

And install lz4 too.
