Operating Systems Linux Red Hat On CentOS, moving space from large free directory to another Post 302632509 by jim mcnamara on Monday 30th of April 2012 08:56:10 AM

/usr should never have user files on it. I am guessing you have a process writing some big logfiles that has filled /usr. CentOS distros do not usually have 10G worth of software, although it is completely possible.

Regardless of adding space you need to see what is going on with /usr
Code:
find /usr -mtime -10 -size +10000 -ls

What you want is a really bad idea. You should fix /usr.

However:
1. lets assume /usr/local has tons of extra software. Reboot into single user mode.
2. As root, use mkdir to create a directory on the /home/ /home/usr/local
3. use tar to move the files
Code:
cd /usr/local
tar cf - . | (cd /home/usr/local && tar xBf -)

4. Be ABOSULUTELY positive this worked correctly.
5.
Code:
cd /usr; rm -R /local;  ln -s local /home/usr/local

You really should either clean up junk on /usr, or add another disk or partition and move file over it the way I described. Using /home will be a mistake. NeutronScott gave you another way to play with partitions

NAME
pmdirs - print out module directories DESCRIPTION
This just prints out the current @INC path, one directory per line. This is for people who don't want to parse through "perl -V" output or hack up their own calls to "perl -e". EXAMPLES
$ pmdirs /home/tchrist/perllib/i686-linux /home/tchrist/perllib /usr/local/devperl/lib/5.00554/i686-linux /usr/local/devperl/lib/5.00554 /usr/local/devperl/lib/site_perl/5.00554/i686-linux /usr/local/devperl/lib/site_perl/5.00554 . This also works for alternate version of Perl: $ filsperl -S pmdirs /home/tchrist/perllib /usr/local/filsperl/lib/5.00554/i686-linux-thread /usr/local/filsperl/lib/5.00554 /usr/local/filsperl/lib/site_perl/5.00554/i686-linux-thread /usr/local/filsperl/lib/site_perl/5.00554 .
