I have a QNAP TS-412. It has 4x 4TB WD Red drives in RAID10.
The poor thing works pretty hard. Virtually 24/7 it runs at 20-30MB/sec as a backup device from a bunch of office computers and a handful of servers.
In the last 2 weeks, seemingly out of nowhere, it has been rebooting every 16 hours or so. It has been under this sort of workload for about 3 years, with only breaks to upgrade the drive capacity every 18 months or so.
Is there anywhere I can go in the console (or via SSH) to see the reason why it is rebooting?
