If you like me, and you have a lot of free disk space then it is a good idea to make money by farming it. Farming is the term we are going to use when you are renting your free space to others. Currently, for some happy reasons, I have 7 TB I can rent. In this article, I will show how to rent your space. Once you get your SIA Coins (SC), it is up to you to trade them.

Everyone knows that CentOS only takes care of some specific core packages. All others, if you want to continue using RPM's, must be used from alternative Repositories. There are many alternatives:

  • EPEL: you will find here many useful packages. Packages get updates for critical bugs.
  • Remi: you will find here backports for most useful packages. 
  • OKay: you will find here some specific packages for servers, audio, and video.

I especially do contributions to the OKay repository. So, if you want to use OKay follow these steps:

  • Install the EPEL repository, you may try typing yum install epel-release. I think at least Centos 7 has it out of the box.
  • Install the okay-release RPM. Type:
    • Centos 6 on 32 bits: rpm -ivh http://repo.okay.com.mx/centos/6/i386/release/okay-release-1-1.noarch.rpm?
    • Centos 6 on 64 bits: rpm -ivh http://repo.okay.com.mx/centos/6/x86_64/release/okay-release-1-1.noarch.rpm?
    • Centos 7 on 64 bits: rpm -ivh http://repo.okay.com.mx/centos/7/x86_64/release/okay-release-1-1.noarch.rpm?

I will post later as I publish some updates or packages.

This is one of the most common issues that could carry issues if you have a MariaDB Galera Cluster. After restarting the cluster, the nodes are not joining. If you look into your log, you may find a line like this:

It may not be safe to bootstrap the cluster from this node. It was not the last one to leave the cluster and may not contain all the updates. To force cluster bootstrap with this node, edit the grastate.dat file manually and set safe_to_bootstrap to 1.
