hello,
For 2 week, I lost sometime some OSD :
Here trace :

needed to interpret this.
I am using Jewel 10.2.10
I am using Erasure coding pool (2+1) + Nvme cache tier (backwrite) with
3 replica with simple RBD disk.
(12 OSD Sata disk on 4 nodes + 1 nvme on each node = 48 x OSD sata + 8 x
NVMe Osd (I split NVMe in 2).
Last week, it was only nvme OSD which crashed. So I unmap all disk,
detroyed cache and recreated It.
From this days, it work fine. Today, an OSD crahed. But it was not an
NVME OSD this time, a normal OSD (sata).
Any idee ? what about this void "*ReplicatedPG::hit_set_trim".
*thanks for your help,*

Regards,
