Thanks to Spencer Cheng for reassurance. I did the upgrade and on reboot seem to have no issues on zfs side. The other query about fslint/czkawka appears to be known, and I found it after digging a bit to one side of my original web search. See https://github.com/qarmin/czkawka/pull/218/files I ran sudo snap connect czkawka:removable-media and USB drives can be searched for duplicates. Similarly, I found that since fslint is also now installed from snap via sudo snap install fslint-unofficial I could sudo snam connect fslint-unofficial:removable-media and then fslint-gui works. Note that just fslint isn't an executable. Not sure which of fslint-gui and czkawka I prefer. Cheers, JN On 2022-12-09 18:09, J C Nash wrote:
I have a pair of SATA spinning disks set up as a zfs mirrored pair. This is NOT my boot volume which is an NVME volume.

I have noticed that fslint and czkawka don't see the /m21z/m21store/ directory, and when I manually enter it in the search set, I get Directories: Provided folder path must exist, ignoring /m21z/m21store/ Included Directory ERROR: Not found even one correct path to included which is required There are a few other apps that can't seem to access the zfs file system. Any advice? John Nash
