Dear Group,

I am looking for advice on ZFS. My computer is running painfully slowly. I
assume this is due to ZFS snapshots eating the entire disk space. My
knowledge of ZFS is almost zero, this box was installed by a friend in the
UK back in 2016 in the days when Ubuntu 16:04 was experimental and is still
running 16.04. Sadly the box is currently stranded in Australia with me so
I can't ask them to look at it.

I have run the following commands

sudo zpool set listsnapshots=on alexandria
zfs list -o space -r alexandria
Which seems to show the space is being eaten by snapshots of the home
directory and oddly that there are no snapshots from before 2019. The
computer is in effect unuseable at the moment. All suggestions are very
welcome.
The box is a dual boot Linux / Windows but the windows partition could be
drastically reduced in size if this is the real problem.
