Hi All, My Problem is DRBD is not mirroring data from Primary node to secondary node.
My Firewall is stopped.
I have done with the Heartbeat. Its working perfectly and also did the
failover.
My current heartbeat configuration satisfied the following crieteria.
When heartbeat starts it also starts the MySQL, HTTPD, and DRBD.
When I shutdown master, VIP is automatically transfer the request on slave
machine.
When I start the Master it automatically take over the control from the
slave machine.
Still I am facing the problem with the DRBD. Though DRBD is not giving any
error message while I start the DRBD service, and I have also checked the
command /cat /proc/drbd,
DRBD is not migrating data from /mysql folder to seconday /mysql folder.

When I am executing mount a on secondary node it give me error like
/O error on device drbd0, logical block 1190144
drbd0: Not in Primary state, no IO requests allowed
Buffer I/O error on device drbd0, logical block 1190145
drbd0: Not in Primary state, no IO requests allowed
Buffer I/O error on device drbd0, logical block 1190146

drbd0: Not in Primary state, no IO requests allowed
Buffer I/O error on device drbd0, logical block 1190148
Buffer I/O error on device drbd0, logical block 1190149
On primary node mount a working properly but in secondary node it give me
the error messages as above.
I have done the below entry on both node in /etc/fstab table.
/dev/drbd0 /mysql ext3 noauto 0 0
I have also created /mysql directory on both node.
I have attached the DRBD.conf file. Please solve the above problem.
Thanks for your support.
Best Regards,
