You are correct, not running atleast wipefs before using luksFormat on the block device was a mistake on my part, but I barely remember making it. I half expected fsck to come up with some errors, so I let it make changes. It is not a volume that is always connected at startup, hence the manual check. It was just the wrong block device. An isLuks check would have returned yes and prevented fsck from running. Maybe libblkid could detect luks partitions?
This happened on a 2 drive raid 1 array, which I have dd backups of, if some how the array can be recovered. Hard lesson learned though.

It seems like it should defensively check where it is an isLuks partition using "cryptsetup isLuks /dev/sda1" before continuing to modify it. I hope such a defensive check can be added.
