I was running low on space on one of my mount, /opt/apps, so I deleted
a 100-MB file, but I still don't have any free space. Issuing df -k
confirmed that I have 0% available. What can be wrong? I am sure the
file I deleted is on the /opt/apps mount point. Is something wrong
with the volumes? Is there some command I can use to reclaim the
space? My server use Solstice DiskSuite and I can go into the
graphical interface, but I just not sure which button to press for the
time being. With Netware, there's the purge command to immediately get
rid of all deleted files and reclaim the space. Does Solaris have
something like that?

TIA!

First guess is that there's another link to the file, which still
exists and is occupying the space.

If you are certain you've deleted the file, and have not
reclaimed the disk space, you may want to reboot your
server. I've come across this a couple of times.

If the process that created the file is still running it probably has the
file open. If a file is in an open state by process 'A' and is deleted by
process 'B', a subsequent attempt to see the file (ls) or to access the file
would be unsuccessful. However, until process 'A' closes the file, the
space held by the file will not be released.

The other possiblity is that the space is hidden by Unix's habit of saving
10% of a file system for root. If you get 0% as root then this isn't the
case. Otherwise, look at the man page for tunefs

That, or some process has the file open. The blocks aren't freed
until no porcesses are accessing the file.

NT tries to do almost everything UNIX does, but fails - miserably.

The use of Windoze cripples the mind; its use should, therefore, be
regarded as a criminal offence. (With apologies to Edsger W. Dijkstra)

If it ain't analogue, it ain't music.

When deleting a file that is already open by another process, the file don't
appear anymore after a ls command, but the space held is not freed by the
system.
Try to kill the process, then then the space will be available for
allocation.

This is not going to help you now but next time you want to free up disk
space that is being taken up by a large file that is not needed execute
the following to have the disk space immediately freed up.

cd /directory

cat /dev/null > filename

df -k /directory

I think you meant "you may *have* to reboot your server". [And that's
usually wrong, as the other responses in the thread should make clear.]

Or wait... maybe I finally understand Bill Gates' financial success!
He's providing a fix for all those junkies out there who get a real
buzz out of rebooting their servers. :-)

Well, also, the 100MB file could have been a large hole, like large
portions of a typical core-file.

Is a process still holding this file open? If so,
you won't really reclaim the space until it lets go
of it.

The command "fuser" (see man page) will tell you the
PID of the varmint responsible.

You can then "kill" the process, or take whatever
action is necessary.

Solaris core files typically do not have holes (SunOS core files did)

It is enough to kill process that used that file

Thank you, everyone who posted replies to my question. FYI, I did
reboot the server but still couldn't reclaim the space, so the problem
wasn't with some processes having a headlock on the file. I deleted
another 100-MB file and voila I had some space available. Strange, but
it worked. I confirmed the space with df -k, as root, at the server
itself, so the problem of Solaris hiding 10% for root wasn't happening.
Any more suggestions?

Perhaps there was more than one link to the file and you removed only one.

The time that I ran into this I called Sun and they said "df -k" wasn't
accurate and it may be reporting an incorrect value. FWIW!!
