Darren nailed it first:
> # lsof +D /var
>
> That command is probably useless because it's explicitly
> looking for files in the /var directory. If they were
> still in the directory, they'd appear in 'du'. You need
> files that aren't in the directory.
>
> Try '+aL1 /var' instead.
# lsof +aL1 /var
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NLINK NODE NAME
auditd 342 root 5u VREG 32,11 16407638005 0 5447 /var
(/dev/dsk/c1t0d0s3)
So, man auditd leads me to man audit which leads me to this interesting snip:
-n Signal audit daemon to close the current audit file
and open a new audit file in the current audit direc-
tory.
# audit -n
# df -ha | grep var
/dev/dsk/c1t0d0s3 17G 66M 17G 1% /var
swap 43G 16K 43G 1% /var/run
Thanks everyone!

Subject: what's filling /var? Oracle sockets?
Hello,
/var is filling up. df reports 15-G used while du reports 62-Megabytes used.
I'm familiar with this type of discrepancy and I've typically taken the easy
route and rebooted. I don't have that luxury this time.
lsof for /var reports the usual suspects syslogd, cron, and sendmail. I've
stopped these processes, checked their log files (which are very small), and
started them up. That should clear any open files they might have right?
lsof for /var also reports 3 oracle-related sockets. Could these sockets be
counting against space for /var? Should I ask the DBA to restart these
processes instead of doing a full reboot?
What else am I missing? Any other suggestions on reclaiming /var?
# df -ha | grep var
/dev/dsk/c1t0d0s3 17G 15G 1.8G 90% /var
swap 43G 16K 43G 1% /var/run
# du -sh /var
62M /var
# lsof +D /var
