Problems with Cache device error. Docker doesn't work anymore! I pre cleared the disk (both) and formatted as usual. Thanks for help!

All those snippets are actualy from the libvirt (VM) image.  You should post your full diagnostics

Okay Squid!

nas-diagnostics-20170923-1857.zip

If you're not using VM's, then disable the VM system and everything will probably come up.  If you are using VM's, then you're going to have to stop the service, delete (and recreate) the libvirt image and then restore the VM xml's from your backups

Hi Squid, VM system disabled and the errors were gone. So thank for your help.

 

Next step is to re-add the 2nd SSD cache drive, re-enabling the VM system and re-installing the ubuntu VM. Will keep you posted. Thank a lot.

The libvirt image is trashed for some reason, so you're ultimately going to have to delete it via VM Settings
