What Are You Doing Right Now
-
2nd crash in 2 days on our DS412+ Synology NAS - I'm rapidly becoming unhappy with this hardware.
-
Have you looked in the logs or anywhere to see what might have caused the crash?
-
I'm having "whipped coffee."
-
@scottalanmiller logs end 40 minutes before we got the first report of issues, very very unhappy.
-
So that suggests a few things.
- The logging system crashed.
- You were hacked.
- Thrashing / OOM.
- Disk is full.
-
It's hard to tell but do you have SAR reports on that box? If so, check them. They often show what has happened in a case like this.

- that's part of it, certainly
- possible, though I can think of more profitable things to do with one's hacking talents
- it's possible, it did run out of memory once before but a patch solved it
- disk is confirmed not full, but good call.
Were I a betting man, I'd point towards some kind of error crashing it's higher functions but leaving disk shares intact. It seems to "crash" about 30 minutes before it ceases to serve files.

what are SAR reports & how would I find / enable / investigate?

Log in through SSH and run....
sarMaybe you will get lucky and see some info.

If I had to put money on it, memory leak leading to thrashing is my guess. I've seen this a lot, it's not that uncommon.
You can do a....
watch free -mAnd that will give you some insight too.

Preparing to do some Redis cluster failovers.

The software on those things actually runs off the storage drives rather than a flash memory so if the hard drives are having any issues it could cause it.
-
Not a design feature that I favour. When making an appliance like that it's much nicer to see the OS on a flash drive (SD card or whatever.)

Good morning to all.
