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.

Note that you have posted your issue in a forum for SUSE's Desktop
product. Since DRBD is provided as part of the High Availability
Extension (HAE) for SLES I suggest that you repost your issue in SUSE's
SLES HAE forum @
https://forums.suse.com/forumdisplay.php?37-SLES-High-Availability-Extension

HTH.

Hi zabadin2,

in addition to Simon's comment about using a SLES forum, it catches the eye that you have both /usr/... and /usr/local/... pathes in your quote. Could you please indicate what software you're actually running (HAE or not, possibly you own packages on top) and check that the commands invoked look for the configuration in those places you actually put them? Is the drbdadm binary the one you're really after?

Regards,
Jens
