Looking for Clustering Solutions to Replace Veritas with EMC SRDF Compatibility
Posted by pusseater_45@reddit | linuxadmin | View on Reddit | 4 comments
Hi all,
We’re currently using Veritas for clustering, but we're exploring alternatives. Our environment is mostly RHEL with some SUSE, and we’re using HP hardware. One option we considered was Pacemaker, but we’ve hit a roadblock. Since we use EMC SRDF, Pacemaker doesn’t seem to have a built-in OCF agent for it, while Veritas offers an agent for monitoring.
That said, EMC SRDF is just one factor in our decision. We're open to other clustering solutions that might better fit our setup, whether or not they support EMC SRDF. Any advice, recommendations, or similar experiences would be greatly appreciated!

I was a big fan of Sun Cluster, but about a decade ago we wisened up when we realized Solaris was dead. Most of this type of general-purpose clustering is gone except the two you already mentioned (and AIX, which you can’t use here). I’d encourage you to look at tech-specific clustering. RAC for Oracle, sentinel for Redis, etc. Use LBs and keepalived where appropriate.
If you have a lot of single-service applications that need HA and aren’t ready to make the jump to k8s, consider a VM infra with automatic live migration as a possibility.

What applications or at least type of applications are you running on these Syms? Is SRDF and volume/vip swinging clustersware your only option? This stuff is pretty long in the tooth.

There's not so many players in this market anymore, besides Pacemaker you can maybe look at HP Serviceguard if that still exists? What's wrong with Veritas in your opinion?
Generally this type of cluster seems to be disappearing as everybody is just building stuff in the cloud and on commodity hardware. Slap on some Kubernetes here and some Postgres streaming replication there and you don't have to deal with this finicky datacenter infrastructure that requires a PHD to do a firmware upgrade. Or that's the theory at least.
But I do agree with /u/H3rbert_K0rnfeld, you probably want a vendor or consultant with experience for most things in that space, since you have to buy a matching set of server/software/SAN for a six digit amount before you can even try the hello-world OCF agent.

Why are you asking poors rich people questions? Ask your value-add vendor.
