[SOLVED] System is running but unreachable after a few days of use

[CK Villa]

Hi,

 

My system keeps getting unreachable after a day or two of usage. The LAN seems to be connected though the lights don't flash (There is just a steady orange light), the HDDs are not being accessed and I am not able to ping the server too. A restart gets it back online but only to repeat this process. Every restart also means that a parity check is started.

 

Unable to make much of Syslog since it only has logs from the time it was restarted and not from when it got hung up.

Enable the syslog server and post that after a crash.

[CK Villa]

I did this, but my Syslog seems to be about 2 GB in size and flooded with messages from my DVR writing files to the FTP server on the Unraid. Anyway I can stop this from happening?

[JorgeB]

Disable the ftp server temporarily.

[CK Villa]

Here you go.

 

I notice a lot of rsyslog errors too.

Nothing obvious, when was the last crash?

[CK Villa]

Ok posting a fresh log of this happening ~1 day ago when I was not at home.

 

My Home Assistant shows the server went down at around the same time 1.48 AM

Is that December 30th? Log looks normal at that time.

[CK Villa]

Attaching both logs. The logs terminate at the point where the system crashed. By crashed, the lights are on and the system is on but not reachable from the network.

 

Also, both times, the last lines of the log go like this:

 

Dec 31 01:48:47 CKVillaServer kernel: DMAR: DRHD: handling fault status reg 3
Dec 31 01:48:4 7 CKVillaServer kernel: DMAR: [DMA Write] Request device [04:00.0] PASID ffffffff fault addr e8000000 [fault reason 05] PTE Write access is not set

 

Is there any possibility this could all just be a bad power supply unit? Is there any test or cues that I need to look for to determine if the power supply is failing? I have a Corsair 650w supply.

device [04:00.0]

This suggests an issue with this controller:

 

04:00.0 SATA controller [0106]: ASMedia Technology Inc. ASM1062 Serial ATA Controller [1b21:0612] (rev 01)
    Subsystem: ASMedia Technology Inc. ASM1062 Serial ATA Controller [1b21:1060]
    Kernel driver in use: ahci
    Kernel modules: ahci

 

Try not using it or installing it in a different PCIe slot.

[CK Villa]

Ok I've moved it to a different PCIE slot. Will circle back if it works out - Haven't had any issues for a few years using this card up till now.

[CK Villa]

Ok that didn't work out. I've pulled the old Maxwell based card out and installed a brand new ASM1166 based card since someone suggested that Maxwell Chipset cards don't play well with Linux on a different forum. Will run this set up for a week or so and revert with what cards were exactly used to solve this.

[CK Villa]

Looks like the Maxwell chipset was the issue. Anyone else that has similar problems, move to a more robust chipset or a server grade one and it should be good.
