Hello Everyone,
I would like to understand if this output is right:
*# ceph df*
GLOBAL:
SIZE AVAIL RAW USED %RAW USED
85.1TiB 43.7TiB 41.4TiB 48.68
POOLS:
NAME ID USED %USED MAX AVAIL OBJECTS
volumes 13 13.8TiB 64.21 7.68TiB 3620495
I only have (1) pool called 'volumes' which is using 13.8TiB (we have a
replica of 3) so it's actually using 41,4TiB and that would be the RAW
USED, at this point is fine, but, then it said on the GLOBAL section that
the AVAIL space is 43.7TiB and the %RAW USED is only 48.68%.
So if I use the 7.68TiB of MAX AVAIL and the pool goes up to 100% of usage,
that would not lead to the total space of the cluster, right? I mean were
are those 43.7TiB of AVAIL space?
I'm using Luminous 12.2.12 release.
Sorry if it's a silly question or if it has been answered before.
Thanks in advance,
Best regards,

Hi German,
Can you post , ceph osd df tree ?
Looks like your usage distribution is not perfect and that's why you got less space
than real.

MAX Avail looks at the fullest OSD and then also takes the nearfull
ratio of an OSD into account which is 85% by defaullt.
It will prevent you from filling up the system 100%.
