Hello guys, during my system house keeping i found this video , which i had recorded some time ago, thought to share with you.
This video is about how we do monitoring of our Production Ceph clusters. In our company we prefer open source software for service monitoring. We have been using the following open source projects all-together for monitoring.
Hey Guys , with this blog post i would like to share live demonstration screen cast that i have prepared using my openstack and Ceph environment.
RedHat Distribution of OpenStack ( RDO ) is one of the most popular openstack distribution for test, dev and production environments. Deploying OpenStack infrastructure using RDO is fairly easy.
However there is no automated uninstall process for RDO (or OpenStack in general).
With the help of this blog I will share my secret sauce that I personally use to uninstall / remove openstack from my development & test environments. This saves me from reinstalling the entire OS and over the OS configurations + it saves time.
Recently I have been playing around Ceph calamari, which is a management and monitoring system for Ceph storage cluster. It provides a beautiful Dashboard User Interface that makes Ceph cluster monitoring amazingly simple and handy.
Getting openstack up and running using RDO is fairly straight forward. However many people have asked to deploy openstack with an existing external network. This method should allow any machine on the network to be able to access launched instances via their floating IPs.
If you are on this page, then you definately know what is Docker , i will not take your time with the introduction part.
While playing with your Ceph cluster , you might have seen HEALTH_WARN cluster status.
Cluster warning can occur due to several reasons of component malfunctioning such as MON,OSD,PG & MDS.
In my case i saw warning due to Ceph monitors, which was like :
Let’s assume ! on a nice sunny day , you receives complaints that your Ceph storage cluster is not performing as it was performing yesterday. After checking cluster status you found that placement groups scrubbing is going on and depending on your scenario , you would like to decrease its priority. Here is how you can do it.
Who doesn’t loves a high performing Ceph storage cluster. To get this you need to tame it , i mean not only Ceph tuning but also Network needs to be tuned. The quickest way to tune your network is to enable Jumbo Frames.
