Hi,



I was wondering what is the overhead of DRBD  on the DRBD  slave in write
intensive system ?

We are thinking about doing with two databases a Active-Passive cluster of
two nodes in cross-breeding fashion.

So one database will be active in 1 machine and the other machine will be
the DRBD slave and the second database will be Active on the first database
DRBD slave machine and the first database machine will be the DRBD slave of
the second database.

This way we thought to  benefit from two fully active machines resources.

Is anyone implemented such architecture ? It is recommended ? What would be
the DRBD overhead in such a case ?

Would it be better to have two databases on 1 machine and the other machine
fully DRBD slave only ?

BTW, the two databases will use mostly InnoDB tables with small amount of
MyISAM tables, which are the most writes intensive.



Thanks,

Eyal Sorek
