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. 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.
