Hello Ernesto,

Thanks, Gilles. I recently opened a PR to improve RBD image listing
(https://github.com/ceph/ceph/pull/39344). In your specific case, I
think that part of the issue could come from calculating the actually
provisioned capacity.
Could you please share the image details (or an `rbd info <img>`
dump), like this?
Here is one of my rbd info :
fcadmin -> sudo rbd --id veeam --image veeam-repos/veeam-repo1-vol1 info
rbd image 'veeam-repo1-vol1':
size 40 TiB in 10485760 objects
order 22 (4 MiB objects)
snapshot_count: 0
id: 16c20a43741ab4
data_pool: veeam-repos.data
block_name_prefix: rbd_data.13.16c20a43741ab4
format: 2
features: layering, exclusive-lock, object-map, fast-diff,

Hi !
I respond to the list, as it may help others.
I also reorder the response.

Hello Cephers,
On a new cluster, I only have 2 RBD block images, and the
Dashboard
doesn't manage to list them correctly.
I have this message :
Warning
Displaying previously cached data for pool veeam-repos.
Sometime it disappears, but as soon as I reload or return to the
listing
page, it's there.
What I've seen, is a high CPU load due to ceph-mgr on the active
manager.
And also stack-traces like this :
[...]
dashboard.exceptions.ViewCacheNoDataException: ViewCache: unable
to
retrieve data
I also see that, when I try to edit an image :
2021-01-18T11:13:26.383+0100 7f00199ca700 0 [dashboard ERROR
frontend.error]

252Fveeam-repo2-vol1>): Cannot read property 'features_name' of

TypeError: Cannot read property 'features_name' of undefined
[...]
But that's perhaps just becaus I open an Edit window on the
image and it
does not have the datas.
The Edit window is empty, and I can't edit things, especially, I
wan't
to resize the image.

Hey Gilles,
If I'm not wrong, that exception (ViewCacheNoDataException)
happens when
the dashboard is unable to gather all required data from Ceph
within a
defined timeout (5 secs I think, since the UI refreshes the data
every ~5
seconds).
It'd be great if you could provide the steps to reproduce it and
some
insights into your environment (number of RBD pools, number of RBD
images,
snapshots, etc.).
Kind Regards,
Ernesto
OK,
As it is now, it always hapens, on the image listing, I have the
Warning and
the list is not always up to date, if I create an image, I must wait
very long
to see it.
Also, I can not edit the 2 big images I have. Perhaps the size is
important,
they are 2 images of 40 TB.
If I create a 1 GB test image, I can edit and resize it.
But impossible withe the big image, the windows opens but all the
fields are
empty.
Also, if it can matter, the images use a data pool (EC 3+2).
I have 2 pools, a replicated one for metadatas veeam-repos (replic
x3), and a
data pool veeam-repos.data (EC 3+2).
My cluster has 6 nodes with AMD 16 cores CPU, 128 GB RAM, 10 8 TB
HDD.
So 60 OSD. Soon doubling everything to 12 nodes.
Usage, as the pool and image names can tell, is to mount RBD image
as a XFS
filesystem for a Veeam Backup Repository (krbd, because nbd-rbd
tailed
regularly, especially during fstrim).
