Right, that's blocks that are being detected as corrupt when they
are read. You can ignore that for now.

That's a corrupted block list of some kind - it should junk the
inode.

I'm not sure why that happens. Is it exiting cleanly or crashing?
Can you take a metadump of the filesystem and provide it for someone
to debug the problems it causes repair?

That marks the inode as "free" which effectively junks it and then
xfs_repair will free all it's extents next time it is run. Basically
you are removing the files from the filesystem and making them
unrecoverable.

Cheers,

Dave.
