I don't know if this is geom related. Feel free to point me elsewhere.
I used gconcat to grow a volume. Then I used growfs. It appeared to be
fine and usable.
But I read that using fsck is a good idea. But fsck complained:
fsck: Could not determine filesystem type
So I used fsck_ufs and it showed many, many errors, such as
UNKNOWN FILE TYPE I=124802
and many others.
I now notice that fsck "fsck: Could not determine filesystem type" even
after a newfs of a /dev/label/MYVOLUME. fsck_ufs completed fine.
After converting new /dev/label/MYVOLUME using:
glacier# gconcat label MYVOLUME /dev/ad0s2 /dev/md1
glacier# growfs /dev/concat/MYVOLUME
We strongly recommend you to make a backup before growing the Filesystem

What can I use to see what these unreferenced files are?
What is strange is in this example above, I did a newfs and fsck
immediately before using gconcat and growfs. So in other words, these
should be empty filesystems with no inodes.
By the way, is using /dev/md* as a geom provider a bad idea?
