ceph df: pools

[krs]

Hello,

How "USED" and "MAX AVAIL" are being calculated for pools? (screenshot ->ceph df)


root@pve01:~# ceph df detail
GLOBAL:
SIZE AVAIL RAW USED %RAW USED OBJECTS
116TiB 51.1TiB 64.6TiB 55.83 5.96M
POOLS:
NAME ID QUOTA OBJECTS QUOTA BYTES USED %USED MAX AVAIL OBJECTS DIRTY READ WRITE RAW USED
rbd 0 N/A N/A 24.2GiB 0.33 7.18TiB 6186 6.19k 0B 12.1KiB 72.5GiB
rbd-sata 1 N/A N/A 20.7TiB 74.23 7.18TiB 5954756 5.95M 100GiB 153GiB 62.0TiB


I think that these values should be bigger.

Also, please check my screenshot (ceph data) from http://florian.ca/ceph-calculator/ in which I have submitted values from all nodes.

Hi !
From what I've seen USED should be the place taken by your VMs and other rbd objects. MAX AVAIL should be (AVAIL - USED).
