ScaleIO - Multiple SDS on Single Linux Node

Question

Trying to find any documentation on how to add the second, third and fourth SDS on a single Linux node in a 3 node Linux cluster Tried searching everywhere Can someone please point me to any document anywhere? Or outline the steps using scli? The only information I can find is this in the User Guide: 'The Multiple SDS feature allows you to take fuller advantage of the server's computing resources, particularly when no applications are running along-side the SDS. Each SDS on the server is unique, with its own name (for example, sds1, sds2), path, and ports used. This uniqueness provides better control over the SDSs installed. Each SDS can be installed, removed, or upgraded independently. It is up to the user to control the scope of the SDS object. For example, if the SDSs are placed in the same Protection Domain, the user must put them in a single Fault Set. ScaleIO currently supports four SDSs running on each server. Each SDS is installed using a different RPM. The user can start with a single SDS, and add more SDSs later.'

Hi,

The multiple installation procedure is described in ScaleIO Deployment Guide under "Configuring multiple SDS on one server" section - it's fairly easy, just needs a properly filled CSV file.

Please let us know if you're stuck with anything.

Cheers,

Thanks Pawel.

I was never able to ever upload a CSV file - I had to go the manual route and built the environment using scli (Three Physical Linux nodes) - similar configs - 1 OS drive + 2 extra drives (1SSD & 1 HDD). I have the GW & IM running on Windows VM. Was getting the error "Error parsing CSV : server didn't respond - code = 404

Could never resolve it so I went the manual route.

I can ping all the IP's back and forth from all the four the servers. I even turned the firewall services off in the Windows VM and stopped and disabled the firewalld on linux, but no luck.

Most comfortable with scli, so long story short - I am looking for a guide that gives me the steps to set multiple sds via scli for my simple configuration, which is - 2 Protection Domains with 2 Storage pools - one Storage pool with SSD's and the other one with HDD's.

Thanks again.

Hi,

See if you can try to downgrade your Java version to 1.8.141 or lower - we had some issues with the newer Java versions and the Gateway.

As in regards to manual instructions - I have never done that, but I think you simply need to install appropriate SDS packages (sdsX- .rpm, where X is a number 1-4 - not the regular SDS RPM) - that should create separate SDS services running on different ports (7072-7075) - and then you can add them to the cluster with "scli --add_sds --sds_ip --sds_port 707X" - and assign appropriate devices to them.

Cheers,
