I noticed that my /root partition was bulding up and found the reason that
logrotate, for whatever reason was not working properly therefore huge files were
created in /var/log/ for syslog etc.
Now I found the reason for it is that the user postgres and wheel can not be found
any longer. I disabled the line "create 0640 postgres wheel" in postgresql run
logrotate and it did its job. /root gained 3 % of 10 Gig.
-- How could users postgres and wheel disappers
and mor important
-- How do I put user postgres and wheel back?
Thanks & regards
