The sfs inodes
An alternate inode scheme is used for
sfs,
in which two inodes are allocated for each file:
-
The first inode, which is always an even-numbered inode,
contains common file information and is essentially
identical to a
ufs
inode.
-
The second (alternate) inode,
which is always an odd-numbered inode,
contains security information.
Programs that report inode usage show
that only even-numbered inodes are in use,
because directory entries contain only even inode numbers.
All alternate inodes on the filesystem
are preallocated by the
mkfs(1M)
command.
