Re: zpool upgrade?

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
   sudo snap install fslint-unofficial
I could
   sudo snam connect fslint-unofficial:removable-media
and then
works. Note that just fslint isn't an executable.

Not sure which of fslint-gui and czkawka I prefer.

Cheers, JN

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 use it for
my data archive, seen via

john@M21:~$ ls /m21z/m21store
2offload  archive  extraset  mainset  OEDback  temp

When I check the status I get:

john@M21:~$ zpool status
   pool: m21z
  state: ONLINE
status: Some supported and requested features are not enabled on the pool.
     The pool can still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
     the pool may no longer be accessible by software that does not support
     the features. See zpool-features(7) for details.

My question is whether there is any significant risk to doing the
zpool upgrade.

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?
