As reported by email from the PingER cronjob we ran out of space on /nfs/slac/g/net/pinger/ (example). This was confirmed as seen below, however there was space in the parent directory in pingerdata.unite.

Looking in more detail at:
$ls -l /nfs/slac/g/net/pinger/* > dir ls: cannot open directory /nfs/slac/g/net/pinger/lost+found: Permission denied Exit 2
Looking in dir, it is apparent that apart from the directories:
pingerlod/, pingerreports/, pingerdata/, pinger_mon_data
most of this data is old and form earlier projects. Rather than lose it we decided to move this other data from
/nfs/slac/g/net/pinger to /nfs/slac/g/net/pingerdata.unite/
