[DRBD-user] Protocol B to improve mysql write performance.

[Deepak.Mantri at shinsei-it.com]

Hi guys,

We are using a heartbeat(2.1.2)+drbd(8.0.11) cluster for Mysql
DB(5.0.x).
This is installed on a Dell PE2950 with external storage(MD3000).The
Database 
Size is 300Gb at present and may scale to 2TB.The failover is happening
fine.
However when we go for a abrupt shutdown of DB and the resources swing
to 
Seconady the time db takes to come up is close to 15min.Initially db
guys suggested 
For some performance tuning changes.Things did not work out.Now we are
being suggested that 
We use protcol B so as to increase the performance and this will in turn
reduce the time for 
Db to come up on secondary.Will changing from protocol c to b help us in
anyway.


Thanks in advance.

Deepak.
