AS6604T Randomly Turning Off

Post by ChubChub »

This NAS is on a battery backup with PLENTY of spare power. I've tested it to ensure it doesn't have issue powering the NAS, all good there. As well, the battery backup doesn't indicate there are any new power events, so it never even needs to turn on.

Every few days, the NAS us just off. I have no idea how to see what is causing it. Is there a log somewhere that shows why it turned off? Maybe a log that says "system shutdown abnormally last time" even? I've had a lot of random problems with this NAS, but it just being off randomly? Really makes me want to just move my data somewhere else because it loses it's mind and eats all of my data.

The kernel log is stored in the temp rootfs (/var/log) which will be gone on hard reboot. On proper shutdown it will be saved in /volume0/.@system/kernellog. The reason to this is not to keep the disks awake writing to the logs. So it's quite useless unless you can capture the last few lines before the system power went out. You can try SSH into the NAS then run:

Code: Select all

tail -f /var/log/messages>>/share/Public/troubleshoot.log 2>&1&
There'll be no output and it's not persistent but if the system were to crash again, hopefully there's something you can see in /share/Public/troubleshoot.log the next time you reboot.

But it's most probably an issue with the backup battery itself or the power adapter. To be sure, try running the NAS few days without the backup battery which means connect the power adapter directly to the power socket.

Replaced the power supply: same problem. Replaced the power supply again: same problem. Connected a smart outlet to it to monitor the power: everything looks normal then it just turns off. Took out the RAM and tested it in my laptop: aok. Tried 1 stick, 2 sticks, in all possible combinations: same.

Takes about 6-7 days before it randomly turns off. Pulled out all the drives and re-installed the OS to a new NVMe: same.

Turns out it's either that the OS sucks, or my hardware sucks. Bad luck I guess. Working on warrantee now.

Probably hardware issue, warranty claim would be wise.
