Quick Install Guide

For a complete installation guide, as well as the self-service portal on AWS refer to the following pages:

Prerequisites

For a complete prerequisite list, refer to section.

We'll consider an example of architecture with 8 identical hosts (named weka01 to weka08). Each host has more than 20 cores, 6 NVME drives, and a single Mellanox NIC.

Using Mellanox NICs simplifies the installation commands (e.g., only single IP for data is required, no need to expose VFs, identification of the interface netmask, and default routing gateway).

If the architecture is different, the installation commands should be slightly changed accordingly.

For a full command set, refer to section.

Installation

Install Weka software on each host:

# deploy the software on all hosts
pdsh -w weka0[1-8] "curl https://[GET.WEKA.IO-TOKEN]@get.weka.io/dist/v1/install/3.8.0/3.8.0 | sudo sh"

Configuration

From one of the servers, form the cluster, set the cluster name, stripe width, and protection scheme, and enable cloud monitoring (DNS is assumed to be set up, otherwise explicit IPs should be used in the cluster create command):

# connect to one of the servers and run the rest of the configuration from there
ssh weka01

# form the cluster and set basic stuff
# using bash, you can provide a compact list of hosts; otherwise, a full list of all hosts should be supplied
# weka cluster create weka01 weka02 weka03 weka04 weka05 weka06 weka07 weka08
weka cluster create weka0{1..8}
weka cluster update --cluster-name=WekaProd
weka cloud enable

Configure the network, drives, and CPUs per host:

# configure network, drives, and cores per host
# replace network, drives, and cores configuration with your actual data

for i in {0..7}
do
    weka cluster host dedicate $i on
    
    # add network NICs
    # e.g., weka cluster host net add $i eth1
    weka cluster host net add $i NETDEV
    
    # add the nvme drives; e.g., /dev/nvme0n1, etc.
    weka cluster drive add $i /dev/nvme0n1 /dev/nvme1n1 /dev/nvme2n1 /dev/nvme3n1 /dev/nvme4n1 /dev/nvme5n1
    
    # set host cores
    weka cluster host cores $i 19 --frontend-dedicated-cores 1 --drives-dedicated-cores 6
done

Check the configuration:

# show hosts info (net, cores, etc.)
for i in {0..7}
do
    weka cluster host resources $i
done

# show drives info
weka cluster drive

# show configuration status
weka status

If satisfied, apply the configuration:

# initialize the hosts
weka cluster host apply --all --force

Set a valid license and start the cluster:

# set a license (classic or payg), as obtained from get.weka.io
weka cluster license set LICENSE_TEXT_OBTAINED_FROM_GET_WEKA_IO

# start the cluster
weka cluster start-io

Check the status:

# show cluster info and status
weka status

You would see a similar output to the following example:

WekaIO v3.10.0 (CLI build 3.10.0)

       cluster: WekaProd (00569cef-5679-4e1d-afe5-7e82748887de)
        status: OK (8 backends UP, 48 drives UP)
    protection: 6+2
     hot spare: 1 failure domains
 drive storage: 82.94 TiB total, 82.94 TiB unprovisioned
         cloud: connected
       license: Unlicensed

     io status: STARTED 7 seconds ago (96 io-nodes UP, 750 buckets UP)
    link layer: Ethernet
       clients: 0 connected
         reads: 0 B/s (0 IO/s)
        writes: 0 B/s (0 IO/s)
    operations: 0 ops/s
        alerts: 1 active alert, use `weka alerts` to list it

Lastly, change the default admin password, and make sure there are no other alerts in the system.
