Hi there,
Recently I experienced crash under heavy load. Not that it didn't pass that much before before but still a scrub, a backup write and a copy over NFS. Scrub started just before crash, say a minute or two while accepting writes at 1.5Gbps. Whole thing has SD boot, L2ARC, SLOG on mirror and 6x SATA in Z2.
After autoreboot scrub continued and found nothing wrong. Drives are encrypted by geli.
I've got files in /data/crash, simple explanation is "double fault" and in addition dump of everything.
How to find what actually has failed?
