Solaris

I am working with sun solaris 9 and I want to install some packages but due to less disk space I am not able to install the packages.
I am giving the output of filesystem--

# df -k
Filesystem kbytes used avail capacity Mounted on
/dev/dsk/c0t0d0s0 2148263 1997593 107705 95% /
/proc 0 0 0 0% /proc
mnttab 0 0 0 0% /etc/mnttab

/export/home/Emerson 36317277 354747 35599358 1% /home/Emerson

it shows that my root dir is filled up 95%..
due to that I am getting the error

cpio: Cannot write "reloc/share/locale/tr/LC_MESSAGES/gcc.mo", errno 28, No space left on device
297544 blocks

So Is there any way to increase the size of the root??

Please help me

thanks in Advance.....

Please check for minfree and if the requirement is not very large then you can reduce the minfree and take some disk space from there.

Initial step would be to housekeep your root fs and see if that improves the situation

what do you mean by housekeep and how can I do that??

delete old and unused files...

i have only useful files and config files only which I can't delete.
So is there any way bywhich I can Increase the size of root(/) without reinstall the OS??

You can grow your partition by two way.

online - without unmounting your file system
offline - unmount your file system


Note: -To grow file system is always a risky think ...make sure you have taken your backup successfully before to use these commands.



Offline method: -

#umount /data
#metaclear D100
#metainit d100 2 1 c1t1d0s0 1 c1t2d0s0
# mount /dev/md/dsk/d100 /data
#growfs -M /data /dev/md/rdsk/d100

Online method: -
#metattach d100 c1d1s1
#growfs -M /data /dev/md/rdsk/d100
