This is somewhat different to what Ulrich had, but his approach might be useful for you, too.

For the SUSE HA offering we limit support to 32 nodes because after this the timing gets so critical that we can't make a support statement anymore. We do have customers with special testing / setups running ~40 nodes, but that really depends on the workload and resources you have to configure. Looks like you've found this, too. pacemaker_remote might be a chance to get more nodes, depending on the services you're running. I wonder if not a cloud solution (with some HA embedded) or a break up in smaller chunks is beneficial. It's not only about the technical capabilities but the mental capabilities of the admins limiting the reliability of such a huge cluster. Just in case, there are HPC clusters with many more nodes, but these address a total different use case. regards, Kai Dupke Senior Product Manager, HA & HPC -- Sell not virtue to purchase wealth, nor liberty to purchase power.

To be honest, it will not fix the root cause which looks like SBD is not getting enough CPU cycles within 4 seconds, which is a lot of time computer-wise. For me it simply looks like the machine should get more CPU resources assinged. Else the VM might behave not as you want and these messages are just a small issue compared to something real going wrong. greetings Kai Dupke Senior Product Manager Server Product Line -- Sell not virtue to purchase wealth, nor liberty to purchase power.

Yes. No. Might be. ^L The concept of geo cluster is cluster of cluster, where the local cluster handles local issue using local timing (seconds), while the geo handles geo issues with much wider timing constrains (minutes, if not hour(s)). A geo setup needs a minimum of 2 sites + an arbitrator site. The arbitrator can be a single node (even a small VM) with the cluster stack running, if only used as a plain arbitrator. In theory you could run without an arbitrator, if the admins are the arbitrators. The other sites needs a cluster stack running, of course this will work with a single node cluster, too. Wonder what setup needs geo redundancy but no local clusters, or what setup needs booth but isn't geo. greetings Kai Dupke Senior Product Manager Server Product Line -- Sell not virtue to purchase wealth, nor liberty to purchase power.

Booth is based on the sites, not the nodes. It doesn't matter how many nodes are at each site as long as the site works on it's own. When a site comes down, then booth uses an arbitrator (site) to determine the failing site is down. For most environments such a switch will not be done automatically but with some organizational interaction. You don't want to switch your data center between EU and US if not really needed, without an SEC filing, or whatever some C* has in mind. Of course this is not a technical limitation but an organizational. greetings kai ___ Users mailing list: Users@clusterlabs.org http://clusterlabs.org/mailman/listinfo/users Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org

Re: [ClusterLabs] [Slightly OT] OCFS2 over LVM
On 08/24/2015 06:20 PM, Digimer wrote: Cluster locking comes at a performance cost. All locks need to be coordinated between the nodes, and that will always be slower that local locking only. They are also far less commonly used than options like nfs. right. Using a pair of nodes with a traditional file system exported by NFS and made accessible by a floating (virtual) IP address gives you redundancy without incurring the complexity and performance overhead of cluster locking. Then you have to copy all data on the network, which limits data throughput. Also, you won't need clvmd either. The trade-off through is that if/when the primary fails, the nfs daemon will appear to restart to the users and that may require a reconnection (not sure, I use nfs sparingly). AFAIK NFS failover includes an NFS timeout, which can be tuned but might give you an extra time till the failover will be finished by the client perspective. Generally speaking, I recommend always avoiding cluster FSes unless they're really required.
