Is there any documentation or scripts regarding manually distribution
for rebalancing
disk with minimal I/O impact on clients io?

Ceph osd df tree give also the balance at host level.
Do you have balancer enabled ?No “perfect” distribution cause that you
cant use the full space.
In our case we gain space manually rebalancing disk, that cause some
objects moves to other osd but you can so fast space available.

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.

Asunto: [ceph-users] Doubt about AVAIL space on df
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,
