How odd, it all seemed to work fine in testing..
Thanks kindly for pointing it out. However, is there any where I can look to find out why drbd failed from master to backup? I can't find anything which would indicate why? Kind regards -- joe.

It should look more like: d1 drbddisk::drbd1 \ Filesystem::/dev/drbd1::/data:ext3 \ mysql \ IPaddr::10.10.xxx.xxx/<netmask>/<interface> The errors you posted regarding mysqld not being able to locate the db directory may be caused by the mysql daemon starting prior to the drbd device being mounted. In that case, you may want to utilize the 'Delay' script in ha.d/rc.d/. Here is an example: d1 drbddisk::drbd1 \ Filesystem::/dev/drbd1::/data:ext3 \ Delay::2 \ mysql \ IPaddr::10.10.xxx.xxx/<netmask>/<interface> It appears very likely your problem is not being caused by DRBD, but rather by the heartbeat configuration. -- Ryan Manikowski ]] Devision Media Services LLC [[ www.devision.us [email protected] | 716.771.2282
