Am I the only lucky one having this problem? Should I use the bugtracker
system for this?

Yes Thanks!!! you are right I deleted the higher created snapshots, and
they are now gone.

With just the one ls listing and my memory it's not totally clear, but
I believe this is the output you get when delete a snapshot folder but
it's still referenced by a different snapshot farther up the
hierarchy.

Still relatively new to ceph, but have been tinkering for a few weeks now.
If I'm reading the various docs correctly, then any RBD in a particular ceph
cluster, will be distributed across ALL OSDs, ALL the time.
There is no way to designate a particular set of disks, AKA OSDs, to be a high
perfo
You can classify osd's, eg as ssd. And you can assign this class to a
pool you create. This way you have have rbd's running on only ssd's. I
think you have also a class for nvme and you can create custom classes.

Indeed, you can set device class to pretty much arbitrary strings and
specify them. By default, 'hdd', 'ssd', and I think 'nvme' are
autodetected - though my Optanes showed up as 'ssd'.

Sounds very useful.

Philip;
There's isn't any documentation that shows specifically how to do that, though
the below comes close.
Here's the documentation, for Nautilus, on CRUSH operations:

Yes I saw that thanks.
Unfortunately, that doesnt show use of "custom classes" as someone hinted at.

Ah, ok. I suspect that isn't documented because the developers don't want
average users doing it.
It's also possible that it won't work as expected, as there is discussion on
the web of device classes being changed at startup of the OSD daemon.
That said...

We use custom device classes to split data nvme from metadata nvme drives. If
a device has a class set it does not get overwritten at startup.
Once you set the class it works just like it says on the tin. Put this pool on
these classes, this other pool on this other class etc.

I have observed this in the ceph nautilus dashboard too - and Think it is a
Display Bug... but sometimes it Shows tue right values
Which nautilus u use?
