I'm using Joomla 2.5.1 on my CentOS 6.2 server running MySQL Server
version: 5.1.61.  All the sudden I get error messages when logged in
as Admin when trying to access the Menu Manager items such as Home.
Things were working fine the night before so I look in the PHP error
log:

So it appears to be MySQL related. So I decided to do a mysqldump of
the database Joomla 2.5.1 is using to rebuild the database and come up
with this error message:

mysqldump: Couldn't execute 'show fields from `cmyzk_assets`': Can't
create/write to file '/tmp/#sql_6da_0.MYI' (Errcode: 13) (1)

I do a ' perror 13' command to see what Errcode 13 means and get this:
OS error code  13:  Permission denied

This doesn't make sense to me because I'm logged in as root doing all
this. Furthermore, I didn't change anything (that I know of).  I
looked to see how MySql is running:

root      1665  0.0  0.0 108256  1432 ?        S    12:15   0:00
/bin/sh /usr/bin/mysqld_safe --datadir=/home/mysql
--socket=/var/lib/mysql/mysql.sock
--pid-file=/var/run/mysqld/mysqld.pid --basedir=/usr --user=mysql
mysql     1754  0.0  0.5 217712 19536 ?        Sl   12:15   0:01
/usr/libexec/mysqld --basedir=/usr --datadir=/home/mysql --user=mysql
--log-error=/var/log/mysqld.log --pid-file=/var/run/mysqld/mysqld.pid
--socket=/var/lib/mysql/mysql.sock

I don't know what the next step should be. I'd appreciate suggestions. Thanks!
