I have a 10TB filesystem I created as above, and recently a crash caused
it to now complain about the filesystem being dirty. When I do an fsck
-p, here's what I get:
# fsck -p /dev/label/vol10
/dev/label/vol10: UNEXPECTED INCONSISTENCY, CANNOT RUN FAST FSCK
/dev/label/vol10: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
