Hi,
I'm new to the list.
I have here a, AFAIK, uncommen setup. Sorry the whole explanation is
a little
bit long, but i want to give you all information in the hope of your
help :-)
Having 3 nodes isn't supported when using haresources.
You need to a) upgrade to something newer than 2.0.7 and b) start
reading http://linux-ha.org/GettingStartedV2
All servers are connected over a backend switch and a frontendswitch
to the
world.
The Backend Network use 10.1.1.0/24
None of the servers use iptabels or another filter mechanism.
Sofwareversions:
Heartbeat 2.0.7
DRBD 8.0.8
Servers:
mysql: 10.1.1.200
backup: 10.1.1.201
media: 10.1.1.202
fe1-fe4: 10.1.1.203-206
"media" server is a http server for image data and the main director
for the
fe? cluster.
"mysql" server is, as you will guess, the mysql server for fe1-4
"backup" server is the fallback for media AND mysql.
from media to backup runs a DRBD
from mysql to backup runs a DRBD
if media fails backup should kick in. (geting drbd primary, firing
up external
ip, firing up internal ip, starting ldirectord, firing up tinyhttpd)
if mysql fails backup should kick in. (geting drbd primary, starting
mysql)
I hope this was understandble :-)
So the problems:
if either mysql or media fails i get
orf-mysql heartbeat: [32004]: ERROR: Both machines own our resources!
orf-mysql heartbeat: [32004]: ERROR: Both machines own foreign
resources!
orf-mysql heartbeat: [32004]: ERROR: Both machines own our resources!
orf-mysql heartbeat: [32004]: ERROR: Both machines own foreign
resources!
but the takeover still seems to work. Is my setup technicly possible ?
Another slight problem i have. in normal the backup and the media
server dont
have a own external ip. if media server is up heartbeat sets the
external ip,
but unfortunatly i can't get him to set the default gw also. Same
case if
backup server takes over. (currently i have 2 spare ips configured
so i can
set the gateway in the normal way, but this is not a permanent
solution)
i dont want to make this mail longer as needed, so you can find all
config
files on http://iamjacks.net/cluster/
any help would be much aprecciated
TIA
Ludwig
