It is certainly designed to be safe and my experience is that it is.
However it is difficult to test all corner cases so it is not impossible that
someone what quite work right.
If something does go wrong:
1/ don't panic
2/ don't try to --create the array to fix it
3/ report all details to this list and I'm 99.9% sure I can get your array
running again with all your data safe.
But I suspect it won't come to that.
