My backup Kubuntu workstation began freezing shortly after boot recently. The problem was recurrent for a week or so and then I just switched the damn thing off. Have picked this up again recently to try and fix, because I would like to make use of this machine’s disks.
I ran MemTest86, and that surfaced no errors. Seems as though the RAM is okay and probably the CPU too.
The first thing I tried after the memory test was to remove the WD Blue 250GB SATA SSD M.2 which was in use as a ZFS cache. And this seems to have fixed the problem! Can’t be sure yet, but so far so good. Will continue to keep an eye on things…

This a note for Future John: Using filesystem capabilities with rsync by Hazel Smith. Use the CAP_DAC_READ_SEARCH capability. AKA: how I learned to stop worrying and love CAP_DAC_READ_SEARCH. There are some more notes over on Linux Capabilities and rsync, from presentation to practice.
