Deleting empty Ceph pool

[Pascal_MTV]

Hi,

We have a pool of Proxmox 3.4 servers, and in the past, someone created a Ceph pool for this cluster. That pool is not used, and I would like to delete it.

# rados df

pool name KB objects clones degraded unfound rd rd KB wr wr KB
rbd 0 0 0 0 0 0 0 0 0
total used 46336 0
total avail 1947273020
total space 1947319356

Can I delete the pool safely from the Web GUI, or deleting it would have other impacts?

Thanks,

Deleting the pool will remove all the PGs associated with the pool from the cluster. It might occur that the cluster complains about not having enough placement groups, then you need to adjust the PGs of the other pools. The pgcalc helps with the calculation: https://ceph.com/pgcalc/
