ESE allocators xfs not showing allocated space

Elastic Orchestration Elastic Cloud Enterprise (ECE)

Hi,

I have setup 3 allocators using the small script on Ubuntu 16.04.
https://www.elastic.co/guide/en/cloud-enterprise/current/ece-topology-example1.html
The servers have each a root drive of 80GB and an extra drive of 1TB
The 3 allocators are only showing 32.48 GB available of 53.48 GB, should be about 1TB
This is just a pilot setup but would like to get the full amount assigned
I have followed a few thread but no luck

/dev/vda1 84G 1.9G 82G 3% /
/dev/vdb 1.1T 5.9G 1.1T 1% /mnt/data

I assume you're looking at the allocator overview in the ECE UI. It's showing the available memory (RAM) not the available disk space.

Dah. My mistake, a newbie.
Thanks for reply.

So how do you see the total disk usage of the allocators?
I deployed a test deployment with 8GB RAM, so the disk showing is 256GB (8x32) 1:32
I can see this in the deployment
Where do I see the total size or remaining disk of the allocaters?

Hi @JeanD-SYD

Currently ECE is very RAM centric in its displays - the assumption is a fixed RAM:disk for a given allocator (set via instance configurations) with sufficient disk space to handle a full RAM allocation - hence the % of RAM in use is a proxy for % of available disk space

(As the 2.x series allows for more flexible RAM:disk configurations, our UI will probably evolve over time to allow people to look at allocators from other resource perspectives)

Alex,

Thanks for the information. Much appreciated
