Re: Arbiter node in slow network

[Strahil Nikolov <hunter86_bg@xxxxxxxxx>]

As Alan mentioned latency is more important.

Also consider using an SSD for all arbiter bricks and set maxpct (man 8 mkfs.xfs) to a high level (I prefer to use '90').

Hi Filipe,

I think it would probably be fine. The Red Hat Storage docs list the important thing being 5ms latency, not link speed:

https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.5/html/administration_guide/creating_arbitrated_replicated_volumes

I haven't used an arbiter configuration yet (still stuck on distribute + replicate, not sure how to migrate). Let us know it goes.

Regards,

Hi glusters,

I'm close to deploy my first GlusterFS replica 3 arbiter 1 volume.

Below I will describe my hardware / plans:

Node1: two bricks, 2 x raid0 arrays 40gbe network
Node2: two bricks, 2 x raid0 arrays 40gbe network
Node3: Arbiter 1gbe network

Between Node1 and Node2, I have a 40gbe network.

But the arbiter has 1 gbe network.

The question is, can arbiter run in a slow network ? It will affect the general performance of volume?

Thank you
