Cache read only till reboot

[Pascal51882]

Hello,

 

I got some problems yesterday evening.

First my NVME Cache went Read Only. I copied all the files to my Array and wanted to reformat it from BTRFS in to XFS.

My Array did not stop so I forced a reboot with sudo reboot -f

After the reboot my Cache started working fine again

I see some errors related to my OS flash drive, but I dont know what to do with them.

How bad is this error? Everything seems to run fine at the moment.

 

I read a lot of posts that BTRFS works really bad on NVME and gets easily corrupt. Is this true?

Should I reformat my cache? With Sata SSD Cache I had no problems in 3 years.

These are about the docker image, you can recreate it.

If these continue you should replace the flash drive, or at least try to re-format it to see if it helps.
