Hello all,
I would like to ask you on the general question about using DRBD.
I have already installed system (SLES10 SP1) where is used also database
on the special 
partition called /database.
This partition is LVM2 partition.
This partition is used by database engine MySQL.
Because of this partition is not replicated yet I would like to
replicate them with DRBD software.
Is it possible to configure DRBD so that /database partition will be
used for database engine after DRBD configuration?
I've made several tests and after configuration of DRBD /dev/drbd0 has
been created for corresponding partition.
/database partition has not been replicated online but /dev/drbd0  has
been replicate.
Could you please help me how to replicate already existing and used
Is it neccessary to reconfigure MySQL database engine for using
/dev/drbd0 or can I use the existing partition?
Best regards
Petr Hracek
