NAS reboots after import attempts

Post by taney »

First off, my NAS has been running fine without any issues for a few years now. This is a unit with a SAS 2008 HBA running JBOD (IT firmware) with 6x WD 3TB drives, 2x Intel X25-E SLC 32GB SSD as mirrored log, 1x 128GB MLC SSD as cache, and a bootable 8GB SSD Transcend SATA drive. Also, running 16GB Kingston ECC Memory.

The other day I was moving files and doing multiple transfers at once and it caused the NAS to reboot and it never recovered.

The NAS would boot to Load NOP GEOM class and it would power cycle every time it got to that state. I would remove each WD 3TB drive one at a time to see if it would boot; no luck. I tried a variety of options. The only bootable options keeping the pool in place was removing the pair of Intel drives (mirrored log). It would be boot but it wouldn't import (e.g. import -m -f tank). It could attempt to import and power cycle once again. I also tried booting it without the drives; hotplugging those drives to perform the import but same thing. I don't mind rebuilding this pool if I have to but I would really love to recover the data first.

Any ideas?
