Hi,

I want to ask who expert with suse here. Currently i have 2 environment, fail over and production. Production use SLES 11SP1 but fail over use SLES11SP2.

Both have application run on apache and database using mysql.

I want to replicate on block level but seem SP2 don't have it. Any idea where i get with complete tutorial?

Thanks.
