unraid lost connection after start array(solved)

[Xjn]

Please help.

My unraid server(6.9.2) failed to start today.After some tries,i found these symptoms.

 

1.If i stop array in time,the unraid system will stay normal as long as i dont start array,GUI and ssh can be accesssed.

2.Shortly after i start array,the unraid server will be unreachable,i cant ping the server through.

I found some error info like

"KERNEL PANIC NOT SYNCING FATAL EXCEPTION IN INTERRUPT"

and

"Dec 31 19:30:52 Tower kernel: BTRFS error (device nvme0n1p1): bdev /dev/nvme0n1p1 errs: wr 0, rd 0, flush 0, corrupt 3, gen 0
Dec 31 19:30:57 Tower kernel: bash[14475]: segfault at 84000018 ip 000055d1b8105b97 sp 00007ffec8b19450 error 4 in bash[55d1b80a7000+b1000]

But i failed to figure out the solve way.

 

Thanks in advance!

Start by running memtest.

Probably not for nothing.

The memory was causing the corruption, removing it will stop additional corruption, not magically fix it.
