Back again with BTRFS errors

[DuzAwe]

Howdy, New ECC ram installed after my last two issues. Woke up this morning to more errors. 

 

Looks like the first error was just cache then loop2 later?

Correct, cache filesystem corrupted first, then it's normal to cause issues with any images using it.

A reboot seems to have put everything back to normal? Scrub came back with nothing. 

 

Should a reboot have done that?

[JorgeB]

Sometimes rebooting can temporarily help, but you'll likely run into issues again.

Anything in the logs to point at what it is? The disk have run fine for months the rc for 6.9 is when this stuff started.

Also, a scrub only checks data and metadata consistency, it doesn't look for filesystem corruption you can do that with the pool offline by typing:

 

btrfs check /dev/sdX1

 

Note that if errors are found running btrfs check in repair model (btrfs check --repair) is considered dangerous, should only be done if told so.

Not that I can see, only that corruption was detected.

Comes back with:

root@thelibrary:~# btrfs check /dev/sdX1
Opening filesystem to check...
ERROR: mount check: cannot open /dev/sdX1: No such file or directory
ERROR: could not check mount status: No such file or directory

You have to replace 'X' with the correct letter for the drive as shown in the unPaid GUI.

 

[JorgeB]

You need to replace X with correct letter, and since it's an NVMe device it would be:

 

btrfs check /dev/nvme1n1p1

 

[DuzAwe]

Well I feel like a fool. Ok Looks clean.

That looks all fine to me.

[DuzAwe]

Welp, Thanks for your help again. I guess Ill be back at some point.
