This is worth clarifying:

You should be careful with the journals. The journal blocks may look
like dinodes, but they should be marked as data blocks. That's because
the journal's data can contain dinodes. Will fsck.gfs2 figure it out
properly? I don't know. It might, but it might not. Better to be safe
with your data.
