Hi All,

 

Help Needed!

 

My server has been randomly crashing ever sense my upgrade to 6.9.2.  Below is some log info. I have attached the full diagnostics info below. Any help or ideas would be appreciated and very much needed. I can't keep running 15 disks 18+ hours continuously.

Thank you sir. I'll take a look and let you know what I found and did.

 

I have stopped all Docker containers which either use br0 or host with the exception of below as I've been running them for well over an 1.5 years with no issues.

 

UniFI                                       br0

Pi-Hole                                    br0

Duckdns                                 Host

Glances                                  Host

 

Hope that solves the problem.

I have attached a screen shot of the terminal below.

 

I rebooted the server and stopped the parity check. Deleted Docker image and switched to directory. Recreated needed dockers but only the ones using bridge for network. Disabled docker and rebooted the server. Server came up this time saying parity is valid. Rebooted the server again in an attempt to go full cycle and insure I had a clean prior shutdown. Server came up normal. I then manually run the mover. Once done, I started a parity check.

 

Time: 6:06:00 AM

Event: Unraid Parity check

Subject: Notice [PEGASUS] - Parity check started

Description: Size: 12.0 TB

Importance: warning

 

Not sure what the next step is but the server is again up with another parity check in progress. Maybe this time it will stay up?

 

Also been thinking of downgrading sense this issue started occurring after my initial upgrade to 6.9.1.

 

Thanks and looking forward on next steps if needed.

Many users didn't have issues running them with v6.8.x but started having issues with 6.9.x, so you'd need to stop all of them to test.

Hi All,

 

The parity checked finished successfully last night. I then did a system reboot , and started a few Docker containers. Those that only use bridge for networking. This morning the server was still up and running but I did notice the following error.

 

Apr 26 00:50:05 Pegasus kernel: WARNING: CPU: 2 PID: 28059 at net/netfilter/nf_conntrack_core.c:1120 __nf_conntrack_confirm+0x9b/0x1e6 [nf_conntrack]

Apr 26 00:50:05 Pegasus kernel: Modules linked in: xt_nat xt_tcpudp veth macvlan xt_conntrack xt_MASQUERADE nf_conntrack_netlink.

 

I’ll attach the log files below. I’m assuming that sense this was only a Kernel Warning message the system didn’t crash. At this point I then turned off auto start for 2 Dockers that were previously running and rebooted the server. The server came up normal. At this point I just leave what’s running and see what happens.

 

I’ll continue to report progress in a day or so assuming the server stays up.

 

Thanks everyone so far for your help and suggestions on this issue.

Hi All,

 

I like to report that my server have been up now for nearly 6 days now and the  last parity check finished. As of right now I'm only  running 5 docker containers all with only use the Bridge Network. As far as the other docker containers that I was previously running prior to the OS upgrade to 6.9.2 I'm in the process of migrating them to a Docker for Windows environment. This server has an Intel(R) Core(TM) i9-9900K CPU @ 3.60GHz, 3600 Mhz, 8 Core(s), 16 Logical Processor(s) with 64.0 GB of RAM. Much more suited hardware that my main storage array.     

 

I just wanted to thank everyone for all there help with this issue.

 

Thanks again.

 

Gary
