I have a 4 server Proxmox server dedicated to ceph. I have ssd pool with 8 ssds (2 per server) , these are enterprises ssds with 10 DWPD rating. I noticed that one ssd, osd.1 wearouts faster then all other ssds. All other ssds show 3% used endurance indicator but but osd.1 shows 6% - all drives were new and all drives and servers worked for last 2.5 years with about 60 VMs on them. Can anybody think of a reason why one osd would show double the wear ? As far as I can see they are setup exactly the same.

Thank you
