Re: [Linux-HA] Many Resources Dependent on One Resource Group
Hi If I well understand, I would have tried : group G1 mandatory B C group G2 advisory D to I order mandatory group G1 than G2 this should work if I understand well your needs. Regards Alain In the simplest terms, we currently have resources: A = drbd B = filesystem C = cluster IP D thru J = mysql instances. Resource group G1 consists of resources B through J, in that order, and is dependent on resource A. This fails over fine, but it has the serious disadvantage that if you stop or remove a mysql resource in the middle of the list, all of the ones after it stop too. For example, if you stop G, then H thru J stop as well. We want to change it so that the resource group G1 consists only of resources B C. All of the mysql instances (D thru J) are individually dependent on group G1, but not dependent on each other. That way you can stop or remove a mysql resource without affecting the others.

Re: [Linux-HA] Many Resources Dependent on One Resource Group

Re: [Linux-HA] Heartbeat IPv6addr OCF
Hi Nick, Could you privide which version of resource-agents you're using? Prior to 3.9.2, IPv6addr requires a static IPv6 address with the exactly same prefix to find out an apropriate nic; so you should have statically assigned 2600:3c00::34:c003/116 on eth0 for example. As of 3.9.3, it has relaxed and the specified nic is always used no matter if the prefix does not match; so it should just work. (at least it works for me) Alternatively, as of 3.9.5, you can also use IPaddr2 for managing a virtual IPv6 address, which is brand new and I would prefer this because it uses the standard ip command.

Re: [Linux-HA] [lvs-users] [Pacemaker] Piranha Project
I know it's not nearly as polished a solution, but have you tried using something like webmin to manage lvs and HA? I have some custom scripts and commands that I have setup in webmin under the custom commands section. This keeps non-linux admins away from shell access. My documents have them login to webmin with a less than priveledged webmin user that can only see custom commands. Not the most polished like I said, but certainly works.

Hi, the first problem might be the multicast traffic between the nodes if your network equipment is not prepared for multicast routing. you can avoid this problem using the udpu transport which switches the inter- node communication to to unicast. google for corosync udpu for further info. The next problem is the availability of a service if the nodes are located in different subnets. Here you definitely will have to implement a dynamic routing protocol to make sure that the pakets are routed the the subnet with the active node. You can use quagga as a cluster resource. But are you sure that you need all this? Perhaps you can setup your network that you have access to the same subnet for both nodes? That would make clustering much easier.

Prior to 3.9.2, IPv6addr requires a static IPv6 address with the exactly same prefix to find out an apropriate nic; so you should have statically assigned 2600:3c00::34:c003/116 on eth0 for example. As of 3.9.3, it has relaxed and the specified nic is always used no matter if the prefix does not match; so it should just work. (at least it works for me) Alternatively, as of 3.9.5, you can also use IPaddr2 for managing a virtual IPv6 address, which is brand new and I would prefer this because it uses the standard ip command.

I tried modifying my netmask to copy yours. And I get the same error, you do: ipv6test_start_0 (node=node-62, call=6, rc=1, status=complete): unknown error So probably a bug in the resource agent.

[Linux-HA] manage/umanage
Hi, I've tested two things : 1/ if we set maintenance-mode=true : all the configured ressources become 'unmanaged' , as displayed with crm_mon ok start stop are no more accepted and it seems that ressources are no more monitored any more by pacemaker 2/ if we target only one resource via the crm resource umanage resname : it is also displayed unmanage with crm_mon ok start stop are no more accepted BUT pacemaker always monitors the resource Is there a reason for this difference ? And is there a simple way to set a single ressource umanage but also to avoir monitoring on this ressource ? Thanks Alain ___ Linux-HA mailing list Linux-HA@lists.linux-ha.org http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
Re: [Linux-HA] Many Resources Dependent on One Resource Group

Resource group G1 consists of resources B through J, in that order, and is dependent on resource A. This fails over fine, but it has the serious disadvantage that if you stop or remove a mysql resource in the middle of the list, all of the ones after it stop too. For example, if you stop G, then H thru J stop as well. We want to change it so that the resource group G1 consists only of resources B C. All of the mysql instances (D thru J) are individually dependent on group G1, but not dependent on each other. That way you can stop or remove a mysql resource without affecting the others. I saw this scenario described in the Pacemaker docs, but I cannot find an example of the syntax. You can use two resource-sets and go without groups, with that crm shell syntax: order o_drbd-filesystem-ip-dbs inf: A:promote B C (D E F G H I J) colocate co_all-follow-drbd inf: (D E F G H I J) B C A:Master Regards, Andreas -- Eric Robinson Disclaimer - March 24, 2013 This email and any files transmitted with it are confidential and intended solely for 'General Linux-HA mailing list'.
