df would give you total space allocated to the filesystem, used space and % of free space.
Whereas du would give you space listings directory wise.
df command should be enough to find out spcae details about a file system, unless you want it directory wise.
Hope it helps.
Thanks!

Hey guys,

My problem is that when I installed Solaris, I allocated way too little diskspace to my / mount (it first became obvious now, however, because of new needs).

A file system has reached 100%. I have tried adding space using chfs -a size=+100 command to that file system. However, the % used is not decreasing from 100%. Is there a way to add more space?
Also, can someone suggest a script to send a mail alert when a file system is reaching 90%.

df(1) General Commands Manual df(1)
Name
df - display free and used disk space
Syntax
df [-i] [-l] [-n] [filesystem...] [file...]
Description
The command displays the amount of disk space available on the specified file system, for example, It also displays the amount of available
disk space on the file system in which the specified file is contained, for example, If a device is given that has no file systems mounted
on it, displays the information for the root file system. Without any arguments or options, displays shows all mounted filesystems,
including those manually mounted without use of the file. The numbers are reported in kilobytes.
Unless the -n option is specified, updates the statistics stored in memory for the file system specified, before it returns the informa-
tion.
Options
-i Also report the number of used and free inodes.
-l Reports on locally mounted disks only.
-n Do not update the file system statistics stored in memory. Instead, return whatever statistics are stored in memory. This prevents
from hanging in the event that a server containing the specified file system is down.
Restrictions
You cannot use the command to find free space on an unmounted file system using the block or character special device name. Instead, use
the command.
Examples
% df
Filesystem Total kbytes kbytes %
node kbytes used free used Mounted on
/dev/ra1a 7429 2085 4602 31% /tmp
/dev/ra0e 30519 14817 12651 54% /usr/spool
/dev/ra0h 313233 122858 159052 44% /usr/staff1
The total disk space is the total space that was created during the making of the file system. The addition of the used space, the free
space and a percentage of reserved space is the total space. The default value for the reserved space is 10%.
