Unraid 6.10.2 crash and unable to start array

[Domotics]

I have a freshly installed unraid running on 6.10.2 which I setup couple of days ago. I then installed all plugins, dockers and VMs i want. at some point today the server went unresponsive and I could not reach the device over network nor via the monitor attached to the server. So i decided to hard-shutdown the system (press and hold the power button), once the server booted, i took a diagnostics (attached) and tried to start the array. after couple of seconds, the browser hung with a popup (saying i need to refresh to go back to previous window) which i followed. for a moment i read a notification on the screen which said something about stale configuration. so i googled and found the below post and deleted the super.dat file and now the array is starting after I reassigned all drives. hopefully no data is lost and it will stay up.

 

I am curious to find any evidence of the crash and what lead to it. Previously I had the 6.10.0 rc-8 and 6.10.0/1 running for several days without any issues. Only change I made is adding new cache (samsung 870 QVO ) and a PCI card with Coral accelerator (mini PCI version), not sure any of this caused crash. I don't have much data to lose at the moment (and I have a backup) but it is a couple of days work getting everything installed from scratch if it decides to crash again.

 

my main HW is

 

Intel i7 12700K (not overclocked)

32GB DDR4 2666MHz

MSI z590 A-PRO MB

Seagate Exos 14TB Parity

2xSeagate Exos 14TB Data

1 x Segate barracuda 6TB

1 x WD RED 6TB

1 x WD Blue M.2 (Cache for appdata/vm)

1x Samsung 870 SSD for normal cache)

 

 

Any hint is appreciated.

The syslog starts over after every reboot, so not much to see, if it keeps crashing you should setup the syslog server and post that log after a crash.

I created a new share named syslog with cache only (on my ssd cache) and pointed the syslog to that share, but it doesn't seems writing any logs there. am i doing it wrong ?

Also, I keep seeing this in the logs, anything to be worried ?
