It's an error in the L1 cache

Oh I see! My CPU is not overclocked, bios is up to date and case is clean and free from dust inside. The PSU may be the problem, I think. It's a cheap PSU that I am using for one month now, waiting my CX600 to come back from service.

Anyway, thank you so much for the time you spent to me. I really appreciate it!
Cheers

I can't specifically identify what may be filling my syslog, any expert guidance would be appreciated. 

 

Something is basically continually writing to your flash drive  and the backup feature of MyServers keeps backing up

You're going to want to post here: https://forums.unraid.net/topic/112745-stop-useless-backups/#comment-1026238, and read the thread so that you can determine what's going on.  @ljm42 will help out if necessary when you post there.

Since I forgot to post about it, yesterday's update for the Upgrade Assistant tests for IOMMU enabled and the tg3 driver running, so that you can decide whether or not to upgrade to 6.10.2

Link to comment

I just updated to 6.10.2, from 6.9.2

 

I got errors at first (once I was able to fix my docker not working, and that cache drive not being recognized, and there being syntax errors.... etc.....) that my flash drive error'd out, and was READ ONLY. This also caused Fix Common Problems to poop the bed super hard.

 

Following the advice, got a new flash drive, transferred the key over.... FixCommonProblems still hates everything about me, and is throwing the same errors. Is this residual from the previous drive, or is there something in the way I have messed everything which basically wrecks whatever flash drive I put it on?

 

Thanks a ton for all that you do.

Hey Squid, i'm getting what appears to be a false positive on a file i created on my USB:
 

/boot/config/usb-rules.cfg corrupted	Your flash drive has possible corruption on /boot/config/usb-rules.cfg.

 

This is the contents of that file (which just maps the zwave and zigbee controller from my HUSBZ-1 to static device entities on boot):

 

SUBSYSTEMS=="usb", DRIVERS=="cp210x", ATTRS{interface}=="HubZ Z-Wave Com Port", SYMLINK+="zwave"
SUBSYSTEMS=="usb", DRIVERS=="cp210x", ATTRS{interface}=="HubZ ZigBee Com Port", SYMLINK+="zigbee"

 

There doesn't appear to be any corruption in the file, i've recreated it just to be sure, so i'm thinking there is some sort of string of characters that the scan is detecting as corruption.

I had some errors with my hardware and now have Unraid 6.10.2 Stable again, but its show a corrupt file on my Boot USB drive. Not sure I can remove this and it will be recreated. Your flash drive has possible corruption on /boot/config/smart-one-backup.cfg. Post your diagnostics in the forum for more assistance. Diag attached. Any help would be greatly appericated. Thanks in Advance.

Since updating to Unraid Version: 6.10.2 after along time of not updating. I have gotten the "Multiple NICs on the same IPv4 network" with the Fix Common Problems Plugin. However in my network settings its list only one network interface. (Screenshots are attached) Any suggestion you have to resolving this would be appreciated. This was the first time my unraid server has been restarted in some time since it has just been working perfectly since I applied the last update. 

 

I am also unable to use WireGuard now as it doesn't let me access the internet only the unraid server from the peer. This is probably tied to the same issue listed.

You seem to be getting continuous errors along the lines of

which indicates that there are issues with your cache pool since the sdd and sdb devices belong to it.

 

Not sure of the best way to proceed - maybe @JorgeB might have a view?

Any advice appreciated!

One of the cache devices dropped offline:

Jun  8 19:56:06 BIGDADDY kernel: ata1: hard resetting link
Jun  8 19:56:12 BIGDADDY kernel: ata1: COMRESET failed (errno=-16)

Check/replace cables, also see here for better pool monitoring for the future.

Does the plugin also inform the user of best practices to prevent common problems?

 

For example:

  • UPS (and configured correctly)
  • Dynamix File Integrity plugin (installed and scheduled)
  • ECC Memory
  • Not sure if I'm missing anything else.  Maybe potential filesystem issues (btrfs vs. xfs recommenations).

No - It's a bit out of the realm of what FCP is supposed to do, and not particularly feasible and would be annoying, and there's many counter arguments against all of those examples.

Installed a new nic this week, and got a "Unable to communicate with github.com" on FCP

 

Realized that I had pointed the new nic's DNS at my pihole, so I changed it, however I still seem to be having some odd behavior even after the error no longer comes up after FCP rescan, including addresses not resolving when using pihole as DNS

 

Feels like I still might have misconfigured something on the ethernet interfaces?

Played around with it a bit, thought I got it working initially - but after unplugging the eth1 the github warning is back.

 

If I plug it back in the warning clears - am I missing something?

 

I did check the BIOS to see if I could just disable the onboard LAN and simplify things, but that's not an option.
