I've been running C2100 systems for my ceph osd nodes. I run 3 SSDs per C2100 for journaling and all is fine once I insert the drives, format and get them mounted. However, after a few days of regular operation, the SSDs one by one just disappear from the OS completely. Techs reseat the SSDs which always gets things working again and the drives show back up via the megacli tools. And the problem starts all over again w/ the drives just disappearing one by one.
The 2.5" SSDs are currently screwed into holes in the 3.5" caddy . This is great b/c it means that I don't need 2.5" to 3.5" adapters. However, the drives disappear.
I tried using 2.5" adapters placed inside of the 3.5" caddy and that didn't change the outcome . SSDs still either virbrate out or just disappear from the OS and need to be reseated.
No problem w/ the 3.5" disks installed in the other bays. No problem with the internal SSDs at all.
I don't have this problem on my R510 systems.
Anyone else having this problem ? Or recommend a solution ?
Thanks
