I have been waiting for the video presentation of a talk given by Chris Mason at this year’s Scale 10x to finally be posted online. The original Scale 10x talks were streamed live, and the website claims that the videos will be posted online soon, however at this point no date has been provided.
In the meantime however, I found a link to another talk given by Chirs, this time hostsed at linuxfoundation.org. In order to view the full video you do need to provide your name and email address, but the process is painless and well worth the 30 seconds it takes to fill in the form.
It appears as though this was put together in December 2011, so it is relatively new and up to date, provides a nice introduction to btrfs, a look at the upcoming feature set, and a list of work that still needs to be done in order to make btrfs production ready.
Here is a link to the first few minutes of the talk:
