I had a hunch that there was a problem on one of my external backup discs, so I disconnected and reconnected it and the system croaked - it became impossible to unlock the screen and a remote ssh was able to connect but fdisk -l did not respond.
I rebooted the system, with trepidation, and all seems well and healthy except the backup disc has an inconsistency in the boot NFS partition.
I am running disc diagnostics but sda, the main internal disc, seems healthy.
