hb tries to release resources before all processes are stopped
|
|
Hi!
I'd like to run multiple mysql-servers on a heartbeat+drbd cluster.
The cluster is working well, but I've a problem with the failover.
Every time I start it, drbd complains that the partition is still in
use so that hb finally stops the failover. I know that hb releases its
resources from right-to-left of the haresources. I suppose the problem
is that mysql's mysqld_multi script just _initiates_ the stop-process
and does not wait, until all mysql-processes are really finished.
These processes need some time but ha thinks that they already
finished and continues stopping the next resource.
My haresources look like this:
www.mydomain.com drbddisk::r0
Filesystem::/dev/drbd0::/var/lib/mysql::ext3 mysqld_multi
How can I solve this problem?
Cheers
Holger
