This is to document for myself and should anyone else need.
Unable to access my storage shares the last bit, rebooting does not resolve. Rebooting takes upwards of four hours to complete.
While had been able to access, now cannot. GUI does respond, but none of the user accounts seem to work. Am able to sign in local as root.
While no errors were on the status page when I was able to access, suspect the system is reaching end of life. End of product life happened some time ago.
Am able to interact with SYSLINUX from the unit directly, it has HDMI and USB ports.
However I ‘lose’ response when I plug in any USB drive.
Am able to ssh, so the system isn’t totaled just yet. I can view the shares, and can ping.
While not ready to build a Nextcloud instance on the Proxmox system yet, I am thinking I should be able to recover the data.
Next step:
Create share
Mount share to NAS
Cli copy data from NAS to another computer as backup
