Hi to all.

I have cluster with  7 pve nodes

After ceph complete to  set the health: HEALTH_OK

I for info  with command check the MAX AVAILABLE  storage :

CLASS  SIZE     AVAIL   USED    RAW USED  %RAW USED
hdd    `106 TiB  96 TiB  10 TiB    10 TiB       9.51
TOTAL  106 TiB  96 TiB  10 TiB    10 TiB       9.51

--- POOLS ---
POOL                               ID  PGS  STORED   OBJECTS USED     
%USED  MAX AVAIL
device_health_metrics      1    1   14 MiB       22   28 MiB             
0     42 TiB
vm.pool                             2  512  2.7 TiB      799.37k    8.3 
TiB   8.95     28 TiB
cephfs_data                      3   32  927 GiB  237.28k 1.8 TiB   
2.11     42 TiB
cephfs_metadata              4   32   30 MiB       28     60 MiB      
0     42 TiB

I understand why is show it like that.

My question is how I can  decrease MAX AVAIL in default pool 
device_health_metrics + cephfs_metadata and set it to vm.pool and 
cephfs_data


Thank you.
