AVAILABLE HARDWARE 3 physical servers (node1-osd, node2-osd, node3-Ceph-client) , model HOST-32H https://www.ovh.ie/dedicated_servers/details-servers-range-HOST-id-2016-HOST-32H.xml -2x 2 TB SATA3 + 2 x480GB SSD (no hardware raid) -10Gbps private network OVH vrack - 1Cloud OVH VPS https://www.ovh.ie/vps/vps-cloud.xml as monitor( for the moment OVH doesn’t support private networking between dedicated and cloud VPS. So, even is incorrect, for testing purposes, the ceph-monitor will be KVM on top of node2) NODE CONFIGURATION sda, sdb - 2X 480GB SSD, CentOS 7 sda1/sdb1 raid1 16G swap sda2/sdb2 raid1 1G /boot sda3/sdb3 raid1 300G / ( needed for libvirt OpenShift KVM’s) sda4/sdb4 noraid, no filesystem, OSD ( optimal size to be established) sda5/sdb5 noraid, no filesystem, journal disk ( optimal size to be established) sdc, sdd 2X2 TB SATA3 no raid, no partition, direct OSD ( separate cluster, for performance reasons, don’t want to mix ssd with sata) NOT INCLUDED IN THIS JOB -Openshift nodes will be setup later as KVM’s ( on top of node2/3). For testing purposes, in this job we shall setup ceph client with docker installation on KVM1 and also on node3-ceph-client, bare metal. -Additional nodes will be added later. After more than 5 -10 node, we consider switching to OpenStack, settings up OpenShift on top of it. So, for the moment, we exclude OpenStack, for maintenance burden and performance penalty. by including another layer. JOB DESCRIPTION -Validate current startup architecture. Details: http://docs.ceph.com/docs/master/start/quick-rbd/ recommends “You may use a virtual machine for your ceph-client node, but do not execute the following procedures on the same physical node as your Ceph Storage Cluster nodes (unless you use a VM).” In this respect, I can’t setup Openshift nodes directly on bare metal ( needs KVM on top of node2/node3) , because Kubernetes persistent volume rbd client could conflict with ceph server libraries. After architecture validation, I shall do myself the basic setup of the servers and http://docs.ceph.com/docs/master/start/quick-start-preflight/ -Setup ceph clusters - Test high availability ( shutdown node1... Afterwards, OSD node2, ceph-mon KVM on node2 and node3-ceph-client should continue serving the testing web app) -Performance analysis of the OVH setup OHV built-in OS installer, with custom kernel, performs network transfer with 589.9MB/s, but doesn’t have KVM, Ceph included. Centos 7 installation from USB iso performs network transfer only with 294.9MB/s Our workaround was to use OVH default installer and then to replace their custom kernel with Centos7 stock kernel, obtaining speeds of 589.9MB/s. It would be nice to identify the OVH installer optimization tricks. -Benchmark web application (vanilla drupal install) ( setup block devices for web files on SATA drives, and mysql on SSD drives) -Performance tuning & benchmark ceph tools - Workflow via Skype share screen with voice ( chat only is excluded) , root access with screen -rx ,with static ip firewall. Thank you!

Looking for someone to diagnose and fix the reason why we can no longer SSH into our server. We can do so via console in cpanel, and login via WHM however putty SSH no longer works. We also have something that keeps crashing our server on a daily basis and need to get to the bottom of what is happening. We believe it is coming from too many SQL queries that are being generated by a ticketing system we have.
