<div dir="ltr"><span dir="ltr"><span>Dear Group, 
<br><br>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.<br><br>I have run the following 
commands
<br><br>
sudo zpool set listsnapshots=on alexandria
<br></span></span><div><span dir="ltr"><span>zfs list -o space -r alexandria <br></span></span></div><div>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.</div><div>The box is a dual boot Linux / Windows but the 
windows partition could be drastically reduced in size if this is the 
real problem.<br></div><div><span dir="ltr"><span></span></span></div><div><span dir="ltr"><span></span></span></div><span dir="ltr"><span><br>NAME                                                    AVAIL   USED  USEDSNAP  USEDDS  USEDREFRESERV  USEDCHILD<br>alexandria                                              1.06G   332G      320K     96K              0       332G<br>alexandria@zfs-auto-snap_monthly-2019-07-13-0141            -    64K         -       -              -          -<br>alexandria@zfs-auto-snap_monthly-2019-08-25-1034            -      0         -       -              -          -<br>alexandria@zfs-auto-snap_monthly-2019-10-09-0831            -      0         -       -              -          -<br>alexandria@zfs-auto-snap_monthly-2019-11-09-2312            -      0         -       -              -          -<br>alexandria@zfs-auto-snap_monthly-2019-12-09-1923            -      0         -       -              -          -<br>alexandria@zfs-auto-snap_monthly-2020-01-23-0728            -      0         -       -              -          -<br>alexandria@zfs-auto-snap_monthly-2020-02-27-0408            -      0         -       -              -          -<br>alexandria@zfs-auto-snap_monthly-2020-03-28-0921            -      0         -       -              -          -<br>alexandria@zfs-auto-snap_monthly-2020-04-27-1130            -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-05-18-0221              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-05-19-0117              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-05-20-0358              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-05-21-0350              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-05-22-0105              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-05-27-0155              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_monthly-2020-05-27-0156            -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-05-28-0349              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-06-02-0055              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-06-04-0725              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-06-09-0753              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-06-10-1034              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-06-17-0905              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-06-23-0415              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-06-29-0722              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_monthly-2020-06-29-0732            -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-06-30-0701              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-07-02-0619              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-07-03-0401              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-07-09-0110              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-07-19-0706              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-08-03-0048              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_monthly-2020-08-03-0055            -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-08-05-0229              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-08-06-0052              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-08-07-0202              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-08-08-1109              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-08-09-1053              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-08-10-0157              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-08-11-0347              -      0         -       -              -          -<br>alexandria@zfs-auto-snap_daily-2020-08-12-0849              -      0         -       -              -
