How did you run fsck on root when unmounted? I would think the only way
you could (easily) do that is to run it on one of the individual disk
slices making up the volume. Since you're potentially writing to a
component of the volume without VxVM knowing, that is also not
recommended. If you didn't do that, please let me know exactly what
your procedure was.
Here's what I would do to make sure that things were consistent.
1) 'dis' all but one plex from the volume.
2) reboot the machine. Fsck will run hopefully cleaning any troubles.
If there is a warning, reboot again and verify that there are no
messages at boot about the volume.
3) Once you're happy that this one plex has a consistent filesystem on
it, 'att' the plexes back to it. This will ensure that the volume is
consistent at a block level.
At this point, you should not see any fsck warnings at boot. If you
continue to get them, I would suspect that the filesystem is not being
unmounted cleanly at shutdown. Perhaps check for any patches that may
