			== Free up space on Other Servers ==

			Many servers start to run out of disk space over time. Often it is caused by unread mail for
			root or log files.

			To find the source of the problems, you use "du" to find where the disk space is being used.
			You can't do a du on /proc or /dev, si I use the command

			[root@virt11 /]# du -hs [a-c]* deprecated [e-o]* [q-u]* var \| tee duhs0

			which produces something like this.

			4.0K backup
			4.0K backup1
			4.0K backup2
			4.0K backup3
			4.0K backup4
			7.5M bin
			47M boot
			4.0K deprecated
			92M etc
			30M home
			8.0K initrd
			541M lib
			16K lost+found
			8.0K media
			0 misc
			8.0K mnt
			0 net
			92M opt
			336K root
			36M sbin
			8.0K selinux
			8.0K srv
			0 sys
			4.0K test
			16K tmp
			1.2G usr
			583M var

			In this case it looks like /var is the problem, so

			cd /var
			du -hs * \| tee duhs9

			Produces

			12K account
			2.6M analog-5.32
			63M cache
			24K db
			4.0K duhs
			4.0K duhs1
			4.0K duhs2
			4.0K duhs3
			4.0K duhs4
			4.0K duhs5
			4.0K duhs6
			4.0K duhs7
			4.0K duhs8
			32K empty
			8.0K games
			16K kerberos
			42M lib
			8.0K local
			36K lock
			457M log
			0 mail
			8.0K nis
			8.0K opt
			8.0K preserve
			8.0K racoon
			240K run
			18M spool
			8.0K tmp
			64K vz
			0 vzagent
			0 vzagent.tmp
			16K vzquota
			1.2M www
			20K yp

			Usually, the problem is in /var/spool or /var/log, due to unread mail
			or excessive log files. You can continue to drill down by doing
			a "cd <sbdirectory>" and another "du -hs *".
