External Ceph-cluster - RBD-storage target not working

[mscd]

Hello,

i have problems to create a RBD-storage target from Proxmox VE to an external Ceph-cluster. I followed the documentation (copied the ceph.client.admin.keyring to /etc/pve/priv/ceph) ... but in the Proxmox webGUI the storage target runs in a connection timeout.

How can I debug problems related to RBD-targets (log-files ?).

Best regards,
mscd

check the sysylog/journal for errors/warnings

also are you sure the keyring has the correct name ? (the storage name must be in the filename; check https://pve.proxmox.com/wiki/Storage:_RBD )
are you sure the username + pool names are correct?

Hello,

my problem was/is related to the ceph attribute

auth_allow_insecure_global_id_reclaim

I had to config the external ceph cluster by

ceph config set mon auth_allow_insecure_global_id_reclaim true

... now it is working ... perhaps one should have a look to adjust necessary informations/adjustments on the proxmox side.

Best regards,
mscd

actually you can update the ceph client on the pve side, see https://forum.proxmox.com/threads/c...ecure-global_id-reclaim-cve-2021-20288.88038/
