@jmangan - if you’re already thinking about throwing the file system under the bus, you could attempt to get to a recent version of the kernel and btrfs-tools version … that way you would not have to deal with the installer right away, but could see whether the newer version of the btrfs tools could possibly fix your issue …
if you want to try, check out this thread:
but I would skip the yum remove btrfs-progs step, as the subsequent poster noted that it could possibly remove Rockstor right with it (which you obviously don’t want).
