 Hello all,

 I have uploaded a script that might help you trace Pacemaker calls to

This sort of detail wasn't available in the logs?

Because the underlying cause remained.


 Anyway, I no longer needed the resource, so I deleted it and now I cannot do 
 a cleanup to remove the failed action.

 Anyway to remove the failed actions?

It should work, unless the shell is being too clever.
Try using the crm_resource tool directly.

 Hello.
 I have next schema of pacemaker cluster:

 Fo1 - Mysql Master  |
                               | - VIP for read and write.
 Fo2 - Mysql Master  |


 Mysql started as cloned resources.
 So my questions are:
 1. When I want to move VIP from one node to other -- can I get a data
 consistent corruption?
 2. How will persistent connections behave?

The answers to these questions are specific to your application (ie. Mysql).
Pacemaker just starts and stops things - it does not get involved in
data replication nor place itself between the application and its
clients.

 Thanks for the help

 my question is

 I had gone through the scripts, where i found in
 ping_update method there is a variable called ACTIVE no.of nodes(host_list)
 active based on this value, for our scenario, can we stop the
 heartbeat/pacemaker process, when the host node cannot ping any other nodes in
 the cluster frame work.

no.  host_list should never contain the addresses of cluster nodes.
the ping RA is intended to test _external_ connectivity.

 provide me your suggestion so that it will help us in
 our context.

 Regards
 Rakesh

 You have to create MailTo resource for each resource or group you would like

and tried to restart the HA process using /etc/init.d/heartbeat restart

No, it's not trying to be clever, at least not here. It's not

 Will add them once the code is in the repo.

The diffs seem to be against the 1.1 code, but this should go

 stay active in case of unclean operation.

Can you please elaborate on the benefits this patch would bring.
Is it supposed to prevent a VG from being mounted on more than
one node?

Looking at the code, it seems like that on the start operation,
the existing tag would be overwritten regardless.

Thanks,

P.S. Moving the discussion to the proper mailing list.

 The tag is always the hostname.

 Dear list,
 
 the default subnet mask for an virtual ip (we use the IpAddr2 resource)

The subnet mask should be deducted from the network interface on

specified using a parameter (cidr_netmask). See

crm ra info IPaddr2

Thanks,

 In our setups we use those virtual ip addresses on
 active/passive two node cluster setups. I have been asked if that should
 not be /24 and why, which I wasn't really sure about.
 
 I just assume that's right and /32 is fine because it only needs to get
 masked locally for this single IP. So I'd like to doublecheck; do you
 think this is correct and why (not)?
 
 Thanks in advance,

 Actually I've been optimizing the placement-strategy lately. It will
 sort the resource processing order according to the priorities and
 scores of resources. That should result in ideal placement. Stay tuned.
The improvement of the placement strategy has been committed into the
devel branch. Please give it a test. Thanks!

Do priorities work for utilization strategy?

Best,

 Do priorities work for utilization strategy?
Yes, the improvement works for utilization, minimal and balanced
strategy:

- The nodes that are more healthy and have more capacities get consumed
first (globally preferred nodes).

- The resources that have higher priorities and have higher scores on
globally preferred nodes get assigned first.
