I will parse that as "so if you lose any node, you lose data?" and the answer to that is yes. If you lose an OST, you lose data. If you lose the MDT you lose the entire filesystem. Lustre assumes that the storage you assign to it to manage is reliable. That is, when you create an OST or MDT, we very strongly suggest you create it out of some sort of reliable storage like RAID 1/5/6 for an OST and RAID 1 for an MDT. > The plan is to add more and more servers, so the hope was to be able to > start with 2 and get some redundancy and then grow. Lustre will give you that ability. b.
