Which file system should I use with Gluster?
I was reading through the Gluster 3.2.5 release notes today and came across the following blurb: Red Hat recommends XFS when formatting the disk sub-system. XFS supports metadata journaling, which facilitates quicker crash recovery. The XFS file system can also be de-fragmented and enlarged while mounted and active. Any other POSIX compliant disk file system, such as Ext3, Ext4, ReiserFS may also work, but has not been tested widely…

I really, really dig Python…

To allow me to start experimenting with PHP and MySQL, I needed to create a test environment…

Most of my readers utilize SSH keys to access remote systems. The security bene fits are well known, and key-based authentication makes automating remote t asks a whole lot easier. When you use key-based authentication it becomes imperative to protect your private key, since a third party could access your systems if they were able to gain access to your account. The SSH key generator (ssh-keygen) will attempt to encrypt your private key by default, and can also be used ssh-keygen to add a password to a private key after the fact…
