getting some strange errors in my syslog

poniz · September 8, 2024

Hello, recently I have been getting stranger errors in my syslog. These errors come up almost every second my log will will full up with all these errors. It seems my cache drive is getting these errors. my cache drive setup is btrfs raid1 2x500gb WD Blue. Not sure if one of my cache drives is failing or what. sdf1 and sdg1 are my cache drives.

Steps i've taken - i ran a scrub / ran a repair none of those help.

i have attached my diagnostics file.

any help would greatly appreciated thank you

Looks like one of the pool devices dropped offline, but the syslog already rotated, so we can't see the start of the issue, reboot and post new diags after array start.

poniz · September 9, 2024

Hello JorgeB

Thank you for taking the time to look at the issue.

The new thing i noticed is a had a notification come up saying can not write to USB now , and i can not download the new update for COMMUNITY APP.

let me know what you think

I have a attached a new diag file after a reboot.

Cache1 dropped offline again:

Check/replace cables and post new diags after array start.

Hello, i replaced cables as you asked. and I have attached the file

Looks like the drive might be ok after swap out the cable but now my docker will not start. Do i have to remake my .img file again or is there another way to get the docker service to start ?

should i be looking at replacing my cache drive or you think it was just a bad cable?

Now that the pool corruption is resolved recreate the docker image:

Then:
