[PVE-User] Cannot list disks from an external CEPH pool

Hi to all!

I have a Proxmox cluster (7.1) connected to an external CEPH cluster 
(octopus). From the GUI I cannot list the content (disks) of one pool 
(but I'm able to list all the other pools):

rbd error: rbd: listing images failed: (2) No such file or directory (500)

The pveproxy/access.log shows the error for "pool1":

"GET /api2/json/nodes/pmx-14/storage/pool1/content?content=images 
HTTP/1.1" 500 13

but when I try another pool ("pool2") it works:

"GET /api2/json/nodes/pmx-14/storage/pool2/content?content=images 
HTTP/1.1" 200 841

 From the command line "rbd ls pool1" is working fine (because I don't 
have a ceph.conf I ran it with "rbd -m --keyring 
/etc/pve/priv/ceph/pool1.keyring ls pool1") and I see the pool contents.

The cluster is running fine, the VMs access the disks on that pool 
without a problem

What can it be?

The cluster is a mix of freshly installed nodes and upgraded ones, all 
the 17 nodes (but one which is 6.4 but without any running VMs) are running:
