Operating Systems Solaris Size missing on /dev/dsk/c0t0d0s3 Post 302609785 by methyl on Tuesday 20th of March 2012 12:04:43 PM

Further to bartus11 , the fuser command can tell you which processes have files open on a filesystem - even if you cannot see the files.

A tidy shutdown of all applications followed by a reboot should give you the true disc space.

If you have cleanup routines which delete files, they may need review to make sure that they do not delete files which are open by an application.

REBOOT(8)						      System Manager's Manual							 REBOOT(8)

NAME
reboot - reboot the system immediately SYNOPSIS
reboot [-f] DESCRIPTION
Reboot can be used to reboot the system after installing a new kernel. It does not inform the users, but does log it's actions in /usr/adm/wtmp and /usr/adm/authlog. The system is then rebooted with the reboot(2) systemcall. If the -f flag is not given then all processes are sent terminate signals to give them a chance to die peacefully before the reboot() call. If the wtmp file exists, reboot logs itself as if it were a shutdown. This is done to prevent last(1) from talking about system-crashes. Reboot is registered as is in the authlog file. Reboot can only be executed by the super-user. Any other caller will be refused, either by reboot(8) or by reboot(2). SEE ALSO
reboot(2), shutdown(8), halt(8), boot(8). BUGS
The error message's given by reboot are not always useful. There are several routines that can fail, but which are not fatal for the pro- gram. AUTHOR
