Hi everybody

Thanks to read this thread and help me if you can

I have installed Mysql on red hat ES release 3 and i was working great.

For my applications, I decided to to put the data directory on another machine. The other machine is a big disk of storage (Adaptec snap server 1 terabyte)
It working great for all applications except Mysql

In fact, i put /var/lib/mysql on another machine and I made a nfs mount

When i try to start mysql i have this :

/etc/rc.d/init.d/mysqld start
Timeout error occurred trying to start MySQL Daemon.
Starting MySQL: [FAILED]

in the error message i have this

051028 11:12:33 mysqld started
051028 11:12:33 Can't start server : Bind on unix socket: Function not implemented
051028 11:12:33 Do you already have another mysqld server running on socket: /var/lib/mysql/mysql.sock ?
051028 11:12:33 Aborting

051028 11:12:33 /usr/libexec/mysqld: Shutdown Complete

051028 11:12:33 mysqld ended

I have verified the permission and everything seems to be ok

I can not find what it is wrong so suggestions are welcome !

while i can't follow exactly what you said local UNIX-domain sockets are different than remote Internet-domain ones
local sockets are sun_family AF_LOCAL/AF_UNIX and since they are local they only require a file path like
/var/lib/mysql/mysql.sock
only processes running on the same machine can compunicate with a local namespace socket.

sockets connecting proceses over a network connection of any kind would have to be family PF_INET
and require aditional features like network transmition protocols machine names port numbers and junk like that.

this is from the bind() api description (BSD)
not that that is alot of help but it does point to the fact that the function call is trying to implement a local not network socket.
