Prepare and enable elasticsearch cluster for Production
By the end of this week I'll be setup ES cluster for GitLab.com. Following work will be done:
- Prepare three nodes of DS13 VMs (8 cores, 56GB, 25600 iops for main, but for other attached disks it will be max 5000)
- 20x1023GB disks, striped LVM (can someone provide estimates here?)
- All in one vmnet
- Prepare monitoring for elasticsearch cluster - https://gitlab.com/gitlab-com/infrastructure/issues/1292
- Improve cookbooks regarding elasticsearch.
Main question for me now is the disk size estimate. So any recommendations on it are welcome.
