NAS RN31443D freezes after a few minutes of use

[andrea_santini]

Hello everyone, I have this problem. The NAS freezes after approximately 30 minutes of use. I'm afraid it's one of the 4 discs. I would like to do a single test for each disk, but I don't understand how to do it. I only find the option to test the whole disk pool.

I still ran this type of test, but after a few minutes the NAS freezes. I also tried running a SCRUB, but it always crashes at 0.7%.

How can I find out which hdd (s) have problems?

I checked the logs, but they don't report anything abnormal.

Grazie

Unfortunately I don't understand what the problem is. I bought another NAS in consideration of the fact that this NAS was already 8 years old. Thanks anyway for the invaluable help.

All stats in disk_info.log look clean?

Are you comfortable using ssh?  It is easy to do read tests on individual drives with smartctl.

It's possible that the freeze isn't linked to a drive issue. Are you seeing any warnings related to a full root partition?

Thank you.
Even using SSH, it crashes after a while.
Monday I check what you told me.

smartctl -x /dev/sda should give you details of what errors (if any) the disks have in their logs (using the appropriate names for the other drives of course).

Over the weekend I tested all drives individually with the WDC special test and all idrives are fine.

I just reconnected the NAS to the network, downloaded all logs and ran smartctl -x / dev / sdx on all drives. No error.
The disk_info.log file also does not report errors.
It is a beautiful mystery.
Let's see if it still crashes.

SMART doesn't catch everything, but that does suggest that its unlikely to be the disks.  It could be power related, or something else going on in the chassis (memory???).

Unfortunately the NAS crashed again.
Tomorrow I try to restart it and check the logs.
I will let you know. Thank you.
