Hello,
I want to continue talking about this bug
http://developerbugs.linux-foundation.org/show_bug.cgi?id=1927
(It is not a bug... but I still have some doubts)
For some operation, you have specified on_fail=fence.
How can the cluster fence the node if you have stonith turned off?
Yes I have specified fence because I want to stop, poweroff, or any to do a
failover to another node when a master node fails.
Except we can't because you don't have the stonith-enabled cluster
option set to true.
I don't know how I can activate a stonith. Is
it possible activate
a stonith with heartbeat software ?
http://www.linux-ha.org/ConfiguringStonithPlugins
I think there isn't enough information about configuration ( I think..).
I want to depend off nodes of the cluster only. I think a posibility
could be ssh, but I can't know how. Where is the information about ssh ?
Yes, you need to wait for 10 minutes _and_ enable stonith.
Without stonith we have no way to clean up after a failed stop.
The problem isn't in stopping operation, is in slaving operation,
In that case, as long as stop can clean up after a failed demote, then
stonith isn't strictly necessary.
What can I do to solve the failed demote ? I need to inform heartbeat
when a master is failed and in this case heartbeat "demotes" the failed
master but it can't be a slave. A failed master in mysql (and I think in
other services as well) can't be a slave, if it fails, it can't be a slave.
If I make a master failed in a valid slave, what do heartbeat then ?
but I
What do you think about the next ?
think I need to change RA but Why is heartbeat trying to change the role of
a failed master node ?? If a node is failed, this node should become
unusable or it could be a stopped resource, I think it could be more
reasonable this situation
Either that of find out why its taking so long to stop the resource
It is not taking so long to stop, it is being a slave...
the same thing applies
but is in this
operation when it is failing. In other hand I need a high timeout because my
server is doing many mysql transactions and it could take about 5 minutes to
stop the mysql server (Mysql Server is using 10 GB of RAM, it must commit
and write remain memory data to disk).
I want to achieve a solution of High availability of MySQL, many people is
trying the same.
Thank you!
