Operating Systems Solaris How to check Utilization of single filesystem

Thanks avronis. Yeah I think the act needs to be cleaned up, but is there someway to quickly redeem this loose space, dangling pointers etc. Without machine reboot or partition remounting.
Someway to flush the memory.

It's not stuff that hasn't been flushed -- the deleted files are literally still in use. Deleting the file doesn't do anything to something that already has the file open -- the file continues to exist, and won't be released from disk until whatever's holding them open lets them close.

lsof doesn't seem to be able to give file names, but you can ask it for every process using / with fuser -v -M /

Quickest and dirtiest way: reboot the system.

you can try that below:
du -ks /* |sort -nr

Hi all

Thanks for the guidance. I ended up rebooting the machine on the weekend because the situation was getting out of hand and good to say i can see the utilization is now down to 3GB as per our "du" output Smilie.

I have now come across a sun script
Code:
nfsfind

would this work to close deleted files still held open by processes?

As long as the file is open by a process, there is no way it can be closed. The file is closed when the application that holds it closes the file, which is usually when the application quits.

Code:
pfiles

The pfilescommand could be used to check which files are open by an application. For files that are delete, pfiles will only list file information but no file name. But be aware. Not all files listed by pfiles without a file name are errors and/or problems that need to be fixed.

Code:
 $ pfiles 19547 
 19547:  /usr/bin/perl ./keepopen 
 Current rlimit: 256 file descriptors 
 0: S_IFCHR mode:0620 dev:298,0 ino:12582934 uid:0 gid:7 rdev:24,9 
 O_RDWR|O_LARGEFILE 
 /devices/pseudo/pts@0:9 
 1: S_IFCHR mode:0620 dev:298,0 ino:12582934 uid:0 gid:7 rdev:24,9 
 O_RDWR|O_LARGEFILE 
 /devices/pseudo/pts@0:9 
 2: S_IFCHR mode:0620 dev:298,0 ino:12582934 uid:0 gid:7 rdev:24,9 
 O_RDWR|O_LARGEFILE 
 /devices/pseudo/pts@0:9 
 3: S_IFREG mode:0644 dev:136,3 ino:79343 uid:0 gid:0 size:222173910 
 O_RDONLY|O_LARGEFILE FD_CLOEXEC

Doesn't sound related, no.

To close the file you either have to convince the application to close it, or kill the application.

The former would be nicer if you can do it. If it's system logs, a SIGHUP to the right daemon might do.

You can get a version of lsof for Solaris from sunfreeware which hopefully provides more illuminating output than fuser.
