Hi Ryan, I think if you could provide more info on the storage systems it would help. Things like total drives per raid set and size of each drive. This is a complicated question, but a simple Googling brings up this interesting article: http://wolfcrow.com/blog/which-is-the-best-raid-level-for-video-editing-and-post-production-part-three-number-soup-for-the-soul/
Imho, without knowing any of these details, my personal preference, unless you're running a database is to do multiple raid-1 sets, stripe them with lvm and drop xfs on them. I would like to add that if your storage provider only offers raid-5 or raid-10 it might behoove you to look for another storage provider. :) -Alex On Sep 21, 2014 8:24 PM, "Ryan Nix" <[email protected]> wrote: > Hi All, > > So my boss and I decided to make a good size investment in a Gluster > cluster.
