Hello,
I have a home server with a ZFS storage array - mirrored VDEVs with 6x 4TB drives. I have been experiencing pretty regular failures of my drives, which are all ST4000 pulled out of the Seagate Backup Plus 4TB drives. I have been lucky to have avoided any major data loss, but they shouldn't be failing this fast. They have reasonably good airflow, and their temperatures are usually reasonably low (one drive is currently at 35C, highest is 43C).
When a drive fails, it will disappear from my SAS card, and rebooting won't bring it back. It appears to be totally dead. The third such drive failed a couple days ago. I'm not sure what would be causing it. The hardware I'm using are, from the SAS card up:
* SAS: IBM M1015 flashed to LSI2008
* SAS Cables: Monoprice 0.75m 30AWG Internal Mini SAS 36-Pin Male with Latch to 7-Pin Female Forward Breakout Cable (new)
* Hot Swap Bay: AMS DS-528SSBA Anti-Vibration 8x2.5" SAS/SATA HDD Backplane Module
Since I recently replaced the SAS cables, I suspect it might be the hot swap bay or the SAS card. Do these symptoms appear to point to what is failing? Could it just be the drives? I haven't heard these drives failing like this from anyone, so I kind of doubt I've been this unlucky.
If this isn't enough information, where could I look? I can't read the smart data on the failed drive, but should I be looking at a particular smart value on the other drives?
Thanks for any advice, I appreciate it.
