gloryboxfailure Posted August 1, 2021 Posted August 1, 2021 This morning I received an alert stating that my system was "unable to write to cache" and "unable to write to docker image". After a bit of forum searching, I shut down my server and checked the connections on the cache drive cables. Upon reboot of the server and restart of the array, unraid is telling me that my cache drive is "unmountable: unsupported partition layout". FWIW, syslog is also throwing out buffer I/O errors like crazy on the cache drive. I've attached the diagnostic log. Is there any way to retrieve the cache drive partition layout and docker container configurations? Any help would be greatly appreciated. I have a new SSD I can use to replace the existing cache drive, but I really don't want to reconfigure my dockers unless I absolutely have to. tower-diagnostics-20210801-0857.zip Quote
trurl Posted August 1, 2021 Posted August 1, 2021 Your docker templates are on flash and Previous Apps on the Apps page will reinstall any and all dockers exactly as they were using those templates. But unless you also have appdata for each docker, it will be a new install. Quote
gloryboxfailure Posted August 1, 2021 Author Posted August 1, 2021 Excellent. Thanks for the help, I will try these options. Quote
