With the ceph update that I nade to 19.2.3 I got warnings like
pg 2.b not deep-scrubbed since 2026-02-27T00:56:11.986819+0100 pg 2.fa not deep-scrubbed since 2026-02-27T05:32:34.264221+0100
It seems that sometimes the nightly deepscrub window is too short. I don#t like warnings in the dashboard from my proxmox cluster.
So I started to deep scrub that placement group (PG) on demand during buisness hours :D
ceph pg deep-scrub 2.b
I have 2048 PGs over 48 OSDs each 8 TiB. it took 20 Minutes to complete that one PG.
