Dear Ceph Users,
After upgrading from version 17.2.5 to 17.2.6 I no longer seem to be able
to create snapshots
of images that have an erasure coded datapool.

Before the upgrade I was able to create snapshots of this pool:

I have looked through the release notes of 17.2.6 but couldn't find
anything obvious regarding rbd and ec pools.
Does anyone else have this problem?
Do I need to change some config setting, or was this feature disabled or is
it a bug?
