due not able restart or start mysql

[root@opx-vpc-db-report-slave-2 ~]# service mysqld status mysqld stopped [root@opx-vpc-db-report-slave-2 ~]# /etc/init.d/mysqld start timeout error occurred trying start mysql daemon. starting mysql:                                            [failed] [root@opx-vpc-db-report-slave-2 ~]# 

i have searched lot on internet not found solution

i have configured raid 0 , mount /mnt directory , symlinc

# ln -s /mnt/mysql_data/   /usr/lib/mysql # ln -s /mnt/mysql_run     /var/run/mysql 

yesterday there replication crashed have ran

set global sql_slave_skip_counter=1; 

and again replication fine

please resolve problem

my configuration details :"-

fedora 6 , mysql 5.0.2  please production db  

it seems permission issue, try disabling selinuza using setenforce 0, restart mysql service, check if mysql has right permissions on mounted device (assuming mounted root or sudo user mysql cannot access)
