Hey Guys,

We had 24 OSDs (2 TB) drives with overall available space of 19.97 TB (replica size - 2 ) on our primary ceph-storage pool.

We added 10 more OSDs (same 2 TB drives) and having 25.42 TB only (while I'm expect to have ~ 28 TB approximately)

Funny thing, that when I added latest OSD (I added all of them 1 by 1), I got less disk available than I've had:

Could someone please explain why so? I somewhere lost mostly 3 TB of space. My pools configured:

Proxmox version: 6.4-13
Ceph version: 15.2.14

Thanks!
