Debian Software RAID Setup

The Problem

Over the past few years space on my server would increase based on the deals found on sites like Slickdeals. After some time this lead to a mishmash of two PATAs and one SATA at 120Gb, 160Gb, and 160Gb respectively on my personal media server. Glad as I was to have all this space it started to become disk management issue since I wanted the bulk of the space consolidated for media. Filling up one drive would require me to move data to another with more space, causing organization and software issues (NFS would not single export multiple mounts).


Last week this all became moot when Outpost advertised a 500Gb SATAII Maxtor drive for 90$. My motherboard was capable for RAID-0 and RAID-1 so I figured it was time to upgrade to a terabyte and bought two.

The initial plan was to create a RAID-0 array (striping for performance), re-install Debian, copy all data, and remove the older drives for noise and heat reasons. With two of them PATA drives, they could stay in the system easily copy straight to the new array. The older SATA drive had the OS and I wanted to keep it around for config reference when I was re-setting up the server. Both of the SATA ports would be used for the new array, not allowing this SATA to remain in the system, this was solved by purchasing a Masscool PATA/SATA external USB enclosure and copying the data from there.

Rackspace and FOSS Report

  • The Rackspace State of Open Source
    As the OpenStack Summit in Barcelona kicks off, Rackspace has released a report entitled ‘The State of Open Source’. With every conference seemingly extolling the virtues of open source software, this report is timely. It manages to differentiate between enterprise open source and the wider open source software market.
  • Why digital transformation needs open source
    As if there wasn't already ample reason for businesses to switch to open source, Forrester analysts Paul Miller and Lauren E Nelson released a report in April 2016, entitled Open Source Powers Enterprise Digital Transformation — CIOs Need To Embrace Open Source Software To Drive Change, which further drives the point.
  • Despite Security Fears, Open Source Is Fuelling Innovation and Cost Savings in UK Businesses
  • Security concerns fail to hold back UK open source success
    However, despite its increasingly common use, many (54%) still perceive external security threats to be a big barrier to adoption, that’s according to a report published by Rackspace. The State of Open Source study, which was conducted among IT decision makers in UK businesses with over 1,000 employees and revenues over £500m, and looks at the ways open source is being used, its benefits, but also what is holding back adoption and business concerns. According to the report open source has come of age with 85% using open source technology to migrate a closed source project to open source. Open source also isn’t just a tool for small businesses; the vast majority (90%) of large businesses are now deploying open source-based enterprise applications, with 25% being completely open source. The reason for the growing adoption is because of the money and time savings. Rackspace found that for each project that had been migrated to open source technology, six out of ten organisations saved on average £30,146 and reduced project lifecycle by six months. Greater innovation was reported by many (49%), and 46% were driven to open source because of the competitive opportunities. Additionally, just under half (45%) said that it enabled them to get products and services to market faster. John Engates, Chief Technology Officer at Rackspace, said: “While open source technologies have been around for many years, it is great to see that enterprise businesses are finally dipping their toes in and seeing the tangible benefits.
