[PVE-User] ceph osd tree & destroy_cephfs

[Сергей Цаболов]

Hi to all.

In my Proxmox Cluster  with 7 node

I try to change some Pgs, Target Ratio and some Target size on some pool.

MAX AVAIL on important pool not changed, I think if I destroy 2 pool on 
ceph is changed.

I read the instructions 
https://pve.proxmox.com/pve-docs/chapter-pveceph.html#_destroy_cephfs , 
I need ask if I destroy CephFS pool is will affect other pools ?

For now I not have there some data not used it for backup or something 
other data.

For now I have :

ceph df
--- RAW STORAGE ---
CLASS  SIZE     AVAIL   USED     RAW USED  %RAW USED
hdd    106 TiB  98 TiB  8.0 TiB   8.1 TiB       7.58
TOTAL  106 TiB  98 TiB  8.0 TiB   8.1 TiB       7.58

--- POOLS ---
POOL                   ID  PGS  STORED   OBJECTS  USED     %USED MAX AVAIL
device_health_metrics   1    1   16 MiB       22   32 MiB 0     46 TiB
vm.pool                 2  512  2.7 TiB  740.12k  8.0 TiB 7.99     31 TiB
cephfs_data             3   32  1.9 KiB        0  3.8 KiB 0     46 TiB
cephfs_metadata         4    2   23 MiB       28   47 MiB 0     46 TiB


And one other question below is my ceph osd tree, like you see some osd 
the  REWEIGHT is less the default 1.00000

Suggest me how I change the REWEIGHT on this osd?


ID   CLASS  WEIGHT     TYPE NAME            STATUS  REWEIGHT PRI-AFF
