Think of "PP"s like chunks of space in your volume group. Increases or decreases in the size of your filesystems will occur in your case 128MB at a time. You can't give a filesystem 127MB or 129MB. It will increase or decrease by 128MB because that is your PP size.
It looks like you have 30 gig free.
238 PPs * 128MB PP size = 30464 MB free
Run this command to change the size of your /usr filesystem. I have mine sized around 3 gig. This command sets the /usr to 3 gig:
If you want to want to increase, you can do 128MB (or whatever size you want) increases like this:
This just adds 128M to whatever is already there. If you try to increase your /usr by 1MB, it will give it another 128MB because that is your PP size.
Also, to see your filesystem sizes in a format that makes more sense, run "df -Im":
I everybody!!
How can i use statvfs() to calculate disk usage and free disk space??
Im using this code:
/* Any file on the filesystem in question */
char *filename = "/home/nesto/test/test.cpp";
struct statvfs buf;
if (!statvfs(filename, &buf)) {

hello,
I have to check the free space on the disk that would work both on Windows and Unix platform e.g on C: \ for Windows and / on Unix. I could use Unix command 'df ' ( my windows system has Unix emulator cygwin and could run 'df ' as well).
But I'd like not to rely on system command but... (1 Reply)
Hi
I am unable to understand the disk layout of one of my disk attached to v240. This is newly installed system from jumpstart.
I am unable to see the free space on backup slice 2 and there are 0 to 8 slices listed when I run format and print the disk info, also there is no reference of... (9 Replies)
I'm getting ready to start a LU from Sol 9 to Solaris 10. I want to ensure that I have enough disk space for future upgrades. What I don't know is what free space Solaris requires.
If I have 10GB of free space in /opt, will Solaris 10 use that for a LU?
Or, do I need to allocate 10GB of space... (5 Replies)
Hi,
I would like to create the new file system(mount point) in our unix server.
before that i would like to know the total free space available in /home directory.
Can you please let me know, how to find free space available for new filesystem?
Be careful with your spelling and... (2 Replies)
Version: Solaris 10 (August 2011) on VM
I am kind of new to Solaris.From VM workstation i allocated 35 GB to this Solaris VM's Disk
The disk was named

Few basic slices for root(8gb), swap(517mb) and /export/home(494mb) were created by the solaris Installer during the... (18 Replies)
Hi,
I need about 500G space in one corporate solaris server.
However, I am not sure which command to use to check this.
There are few volume groups in the server, and I deleted unused, old volume groups to clear some space.
However, now I am not sure how to check the free space itself.

df
DF(1) BSD General Commands Manual DF(1)NAME
df -- display free disk space
SYNOPSIS
df [-agklmn] [-G | -i | -P] [-t type] [file | file_system ...]
DESCRIPTION
df displays statistics about the amount of free disk space on the specified file_system or on the file system of which file is a part. By
default, all sizes are reported in 512-byte block counts. If neither a file or a file_system operand is specified, statistics for all
mounted file systems are displayed (subject to the -l and -t options below).
Note that the printed count of available blocks takes minfree into account, and thus will be negative when the number of free blocks on the
filesystem is less than minfree.
The following options are available:
-a Show all mount points, including those that were mounted with the MNT_IGNORE flag.
-G Display all the fields of the structure(s) returned by statvfs(2). This option cannot be used with the -i or -P options, and it is
modelled after the Solaris -g option. This option will override the -g, -h, -k, and -m options, as well as any setting of BLOCKSIZE.
-g The -g option causes the numbers to be reported in gigabytes (1024*1024*1024 bytes).
-h "Human-readable" output. Use unit suffixes: Byte, Kilobyte, Megabyte, Gigabyte, Terabyte, Petabyte, Exabyte in order to reduce the
number of digits to four or less.
-i Include statistics on the number of free inodes.
-k By default, all sizes are reported in 512-byte block counts. The -k option causes the numbers to be reported in kilobytes (1024
bytes).
-l Display statistics only about mounted file systems with the MNT_LOCAL flag set. If a non-local file system is given as an argument,
a warning is issued and no information is given on that file system.
-m The -m option causes the numbers to be reported in megabytes (1024*1024 bytes).
-n Print out the previously obtained statistics from the file systems. This option should be used if it is possible that one or more
file systems are in a state such that they will not be able to provide statistics without a long delay. When this option is speci-
fied, df will not request new statistics from the file systems, but will respond with the possibly stale statistics that were previ-
ously obtained.
-P Produce output in the following portable format:
If both the -P and -k option are specified, the output will be preceded by the following header line, formatted to match the data
following it:
"Filesystem 1024-blocks Used Available Capacity Mounted on
"
If the -P option is specified without the -k options, the output will be preceded by the following header line, formatted to match
the data following it:
"Filesystem <blksize>-blocks Used Available Capacity Mounted on
"
The header line is followed by data formatted as follows:
"%s %d %d %d %d%% %s
", <file system name>, <total space>,
<space used>, <space free>, <percentage used>,
<file system root>
Note that the -i option may not be specified with -P.
-t type
Is used to indicate the actions should only be taken on filesystems of the specified type. More than one type may be specified in a
comma-separated list. The list of filesystem types can be prefixed with ``no'' to specify the filesystem types for which action
should not be taken. If a file system is given on the command line that is not of the specified type, a warning is issued and no
information is given on that file system.
ENVIRONMENT
BLOCKSIZE If the environment variable BLOCKSIZE is set, and the -g, -h, -k and -m options are not specified, the block counts will be dis-
played in units of that size block.
