And you can use xfs_growfs for your purpose.
You extend the filesystem *after* you've grown the array. The act of
growing the array has caused the filesystem to crash. That should NOT
happen - the act of growing the array should be *invisible* to the
filesystem.
In other words, one or more of the following three are true :-
1) The OP has been caught by some random act of God
2) There's a serious flaw in "mdadm --grow"
3) There's a serious flaw in xfs
3) should not be possible because as long 2) is running the filesystem
should not know that anything is changing at all - even "should" is the
wrong word: MUST NOT
