Errors while creating a container on a remote RBD Pool

[brosky]

Hi,

I have added a remote rbd pool (ceph cluster) to a proxmox machine that is not in that cluster. (added via GUI and copy the keyring in /etc/pve/priv/ceph/xxxx.keyring)

Things I noticed:
- after the RBD pool is added, I need to restart pvestatd.service so that the GUI shows the pool without errors (not stated in the docs)
- browsing through other local mounted storages is very slow after the RBD pool mount. Example, clicking on "Summary" shows nothing for 3-4 seconds.
- while creating a VM, I have this log :


Task viewer: VM 105 - Create

LXC has the same issue:

Am I missing something ?

These are nothing to worry about.
In the case of an external Ceph storage, no config will be available locally. It will still try to load it locally, resulting in those warnings.

Everything seems to work just fine, except for those warnings, right?
