What it means is that you read a piece of metadata that did not match any of the metadata magic numbers. hard to say whether it might be an xfs bug I think; this does come up occasionally though and it'd at least be nice to print more details on the error (what the magic *was*, what block, etc) Do you happen to have the repair output? Did your md raid lose power w/ write cache enabled? -Eric > xfs_da_btree.c.
