Hi!

Im runnin an debian11-instance by Proxmox VirtualEnviroment 7.3.-4. In this instance is docker installed:

If I try to build an new docker-container of the ERP-system “metasfresh”, the buildprocess fails after a while with this error:

Service ‘db’ failed to build: failed to register layer: Error processing tar file(exit status 1): replaceDirWithOverlayOpaque(“/etc/X11”) failed: createDirWithOverlayOpaque(“/etc/rdwoo440164177”) failed: failed to mkdir /etc/rdwoo440164177/m/d: mkdir /etc/rdwoo440164177/m/d: input/output error

Any ideas how to fix this? Thank you for all inputs!
