Operating Systems Solaris / file system full issue Post 302277432 by incredible on Friday 16th of January 2009 09:35:50 AM

Unix doesnt actually release the space taken by deleted files until the last reference to them is gone.
This includes processes having the file open.

The usual cause is large log files that are still being written into.

So the only work around to rebooting is to stop and start the application in question.
Or otherwise persuade it to "rotate" its logfile.
Some application will do this on receiving a HUP or provide another mechanism to do the same thing.

you could also run a find in the /proc filesystem & looks for any open file with link count 0. this file is at fault. then find the process holding the file & restart the process. Something like: find /proc -type f -links 0 -ls

AA-UNCONFINED(8)						     AppArmor							  AA-UNCONFINED(8)

NAME
aa-unconfined - output a list of processes with tcp or udp ports that do not have AppArmor profiles loaded SYNOPSIS
aa-unconfined DESCRIPTION
aa-unconfined will use netstat(8) to determine which processes have open network sockets and do not have AppArmor profiles loaded into the kernel. BUGS
aa-unconfined must be run as root to retrieve the process executable link from the /proc filesystem. This program is susceptible to race conditions of several flavours: an unlinked executable will be mishandled; an executable started before a AppArmor profile is loaded will not appear in the output, despite running without confinement; a process that dies between the netstat(8) and further checks will be mishandled. This program only lists processes using TCP and UDP. In short, this program is unsuitable for forensics use and is provided only as an aid to profiling all network-accessible processes in the lab. If you find any bugs, please report them at <http://https://bugs.launchpad.net/apparmor/+filebug>. SEE ALSO
