Hi,

I am having a problem with disk capacity. When i do df -h, i get the following output.

> df -h

i want to reduce the 100%, can someone help me with this? where the folders to view to see the usuage for that disk alone.?

thanks

Very few files in root should change. Assuming that this is a recent problem, a list of data files that changed in past couple of days should do it.

find / -mount -type f -mtime -2 -print

It will probably be something like /dev/imaginary/tape/drive

Actually, you might just be having a problem with how small you / filesystem is. According to your output it is only 940 MB. But the full install of Solaris 9 is bigger than that.

I see that you did split off /var, /opt, and /user on their own which probably helps with that. Still, 940MB is pretty small for the root filesystem.

See what the find command Perderabo shows you. If that doesn't turn up enough stuff for you to delete just increase the mtime to get older files. But you may end up finding there just isn't much that can be deleted and the problem is you can't fit the OS comfortably onto that small of a filesystem.

I have a full install of Solaris 9 and my root is 484 MB total. Currently 33% are in use. Most of the 298 MB that are free are not likely to be used. What do you think might go there? I would argue that 940 MB is much too big.

You could look for files in the '/' filesystem that are very large and remove them if they are not required. You can use find:
This will give you a listing of files in the / filesystem that are above 50MB in size.

hey,

i probably didnt get what you were saying, i am sorry for that.. i tried to get a list of files above 50 mb.. there too many of them.. heres a sample...

i couldnt get the print out as desired for # find / -mount -type f -mtime -2 -print
i know i writing some parameters wrong.
/etc/shadow
/etc/logadm.conf
/etc/lp/printers/lj6mpc/faultMessage
/etc/skip/randseed
/etc/.pwd.lock
/etc/rmtab
/.dt/sessions/lastsession
/.dt/startlog
/.dt/sessionlogs/shiva_DISPLAY=:0
/.dt/Trash/.trashinfo
/.Xauthority
/.TTauthority

also, there are abot 5 files like messages0, messages1 in /var/adm, which occupy some space. could i get rid of them. or what abot the root mail, which no one uses, the mail folder shows lot of space taken up. how do i get rid of these.. will it help

thanks once again.

Umm.. in the command
find / -mount -type f -mtime -2 -print

that 2 is a number of days. It would have worked had it been run promptly.

And no, /var is a separate filesystem. Cleaning that up will not help /.
