mysql cluster on NFS

[shah rizal]

I have setup mysql cluster server using mysql-max-5.0.16-freebsd5.3-i386. The machine works fine when the data restore into local. This is my config.ini

sql-mgm# more config.ini
[NDBD DEFAULT]
NoOfReplicas=2
[MYSQLD DEFAULT]
[NDB_MGMD DEFAULT]
[TCP DEFAULT]
# Managment Server
[NDB_MGMD]
HostName=61.6.32.28 # the IP of THIS SERVER
# Storage Engines
[NDBD]
HostName=61.6.32.27 # the IP of the FIRST SERVER
DataDir= /usr/local/mysql/data
[NDBD]
HostName=61.6.32.26 # the IP of the SECOND SERVER
DataDir= /usr/local/mysql/data
# 2 MySQL Clients
# I personally leave this blank to allow rapid changes of the mysql clients;
# you can enter the hostnames of the above two servers here. I suggest you dont.
[MYSQLD]
HostName=61.6.32.27
[MYSQLD]
HostName=61.6.32.26

The problem occurs when I try to store data into filer (NFS).
When I edit data directory pointed to NFS link, this is the message appeared

*Cannot become daemon: /usr/local/mysql/data/ndb_3.pid: lock test failed: Operation not supported

When I disabled link to filer, I can start ndb process but mysql service failed to start
Starting MySQL................................... ERROR!
