Hi all, I have just upgraded my system from 13.1 -> 13.2 and now the maximum=20 file system size keeps going down and 'df' is showing as hardly any=20 space left on the drive? # df -h Filesystem=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0= =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 Size=C2=A0=C2=A0=C2=A0 Used=C2=A0=C2= =A0 Avail Capacity=C2=A0=20 Mounted on zroot/ROOT/default=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0= 37G=C2=A0=C2=A0=C2=A0=C2=A0 36G=C2=A0=C2=A0=C2=A0 720M 98%=C2=A0=C2=A0=C2= =A0 / Yesterday when performing the upgrade I did notice this which happened=20 after deleting over 20GB of 'preview' files for one of my webapps in=20 /usr/local/www/ which is hosted by the apache2 port.

Just as an FYI, it's the standard upgrade from the FAQ page: freebsd-update -r 13.2-RELEASE upgrade The root system is mirrored between two disks: =C2=A0=C2=A0=C2=A0 NAME=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 STATE=C2= =A0=C2=A0=C2=A0=C2=A0 READ WRITE CKSUM =C2=A0=C2=A0 =C2=A0zroot=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 ONLINE=C2=A0= =C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 0=C2=A0=C2=A0=C2=A0=C2=A0 0=C2=A0=C2=A0=C2= =A0=C2=A0 0 =C2=A0=C2=A0 =C2=A0=C2=A0 mirror-0=C2=A0 ONLINE=C2=A0=C2=A0=C2=A0=C2=A0=C2= =A0=C2=A0 0=C2=A0=C2=A0=C2=A0=C2=A0 0=C2=A0=C2=A0=C2=A0=C2=A0 0 =C2=A0=C2=A0 =C2=A0=C2=A0=C2=A0=C2=A0 ada0p3=C2=A0 ONLINE=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0 0=C2=A0=C2=A0=C2=A0=C2=A0 0=C2=A0=C2=A0=C2=A0=C2=A0= 0 =C2=A0=C2=A0 =C2=A0=C2=A0=C2=A0=C2=A0 ada1p3=C2=A0 ONLINE=C2=A0=C2=A0=C2= =A0=C2=A0=C2=A0=C2=A0 0=C2=A0=C2=A0=C2=A0=C2=A0 0=C2=A0=C2=A0=C2=A0=C2=A0= 0 Reading up a little I found a posting where someone had been trying to=20 delete snapshots which where taking up huge areas of space.

Would anyone be able to help on this one? Basically I just want to=20 create space again on the drive as currently I am unable to even fetch=20 the @ports collection with only 720M of disk space being shown as=20 left.... cleaning @ports should have given me quite a few GB spare but=20 nothing happening at all?? Many thanks. Kaya
