How to rename a ceph pool

[tkn-teamf]

How can I rename a ceph pool?

Using `ceph osd pool rename ceph-a_hdd_data_replicated ceph-amsterdam_hdd_replicated` storage.cfg gets not updated.

Is there a proxmox tool for doing so?

TIA, Thomas

Hello,

Using `ceph osd pool rename ceph-a_hdd_data_replicated ceph-amsterdam_hdd_replicated` storage.cfg gets not updated.

This is expected, since you used the `ceph` instead of `pveceph`. The command `ceph osd pool rename` doesn't care about the `/etc/pve/storage.cfg` that means you should to edit the /etc/pve/storage.cfg manually.

I tried to edit '/etc/pve/storage.cfg'. But how can I activate the changes I made there (without rebooting the hypervisor)?

You changed the "pool" option for the storage right?

For example from:

rbd: myrbd
    content rootdir,images
    krbd 0
    pool myrbd

to

rbd: myrbd
    content rootdir,images
    krbd 0
    pool changedpool

The change should be used right away. Do you see the contents and usage if you click on the storage in the GUI?

I changed to

rbd: changedpool
    content rootdir,images
    krbd 0
    pool changedpool

Because I want to see the new pool name in proxmox gui.

That is a problem!

The name of the storage is used in every guest config that has a disk on the storage and to match the keyring to authenticate against the Ceph cluster located in /etc/pve/priv/ceph/{storage}.keyring

If no disk image is on the pool, then you only need to rename the keyring file.

Okay. Thank you. Maybe you could change this sometime, to use numerical IDs and not alphanumeric names as references.
