      Create the lvm (this is where you can do things like setting up ssd cache as well if you want)

      Wouldn't he want a raid 1 for the SSD Cache too though? Just in case a drive fails. A lot of points of failure there across the board.

        If the data has any value, you don't do RAID 0 anyway. If speed is important, then adding fast cache drives makes a lot of sense, and is one reason to use RAID 0 (speed of access to ephemeral data). If the single cache drive fails, it just falls back to functioning without a cache.

          I read that if there is data loaded in the failed drives (ala memory) that data is lost. Is that not the case?

              Yes. This is why you don't load valuable data on a RAID0, ever.

                Well yeah for sure, but I mean specifically the cache

                  It very well could be, but I figured instructions can never be a complete waste of time, even if the OP isn't serious.

                    The cache drive shouldn't be holding data waiting to be written to the array. The best way to go without getting extremely complicated is using it as a read only cache. You can of course do write caching as well, but then you get into all sorts of complications in managing data should something happen to a write cache drive.

                      Understood. Thanks for the clarification

                        MOst systems require RAID 1 for cache.

                          Apparently I'll need to take a look at the caching options for LVM again, didn't think it mattered.
