Checked the SMART status. All of the Samsungs have Wear Leveling Count equal to 99 (raw values 29, 36 and 15). I'm going to have to monitor them - I could afford loosing one of them, but loosing two would mean loss of data.

the massive rebalancing does not affect the ssds in a good way either. But from what I've gatherd the pro should be fine. Massive amount of write errors in the logs?

service ceph start osd.$IDAny thought greatly appreciated !Thanks,--Andrija Panić
