All I did was truncate the array using "mdadm --grow /dev/md0 --array-size" and then resize the array using "mdadm --grow /dev/md0 --raid-devices=6" so I guess I didn't resize the XFS FS first. Is that something I can do now or am I screwed? Ouch. I don't know if you are screwed. Unless you wrote to it, in which case you probably are. But you haven't been able to mount it, I presume, so you might be OK. It depends on whether the reshape is reversible. If it's not reversible, you'll have to ask the XFS experts xfs@oss.sgi.com or linux-xfs@vger.kernel.org Neil?
