[Klug-general] disk space issue

[Dan Attwood]

ok just tested that a dev server and that worked do I've push it to live.

That given me some more breathing room. However I don't think this is the
root cause of the problem as a df -h still shows:


Filesystem      Size  Used Avail Use% Mounted on
/dev/sdb1       370G  342G   24G  94% /var

so there is still 30 gig odd being gobbled up somewhere
