>Description:

Many of the utilities in e2fsprogs seem to think that devices are zero
bytes in size, and complain that a specified disk device is
"not a block special device". FreeBSD does not support block special devices.

e2fsck does not seem to work at all. It complains about a "short read"
on filesystems that mount fine with mount_ext2fs and do not have any
problems when checked with e2fsck running on Debian 3.0 or my modified
version of NetBSD's fsck_ext2fs

>How-To-Repeat:

# mke2fs /dev/ad1s1
mke2fs 1.32 (09-Nov-2002)
/dev/ad1s1 is not a block special device.
Proceed anyway? (y,n) y
mke2fs: Device size reported to be zero.  Invalid partition specified, or
        partition table wasn't reread after running fdisk, due to
        a modified partition being busy and in use.  You may need to reboot
        to re-read your partition table.

# e2fsck -f /dev/ad1s1
e2fsck 1.32 (09-Nov-2002)
The filesystem size (according to the superblock) is 194560 blocks
The physical size of the device is 0 blocks
Either the superblock or the partition table is likely to be corrupt!
Abort<y>? no

Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information
Error reading block 4 (Attempt to read block from filesystem resulted in short read) while reading inode and block bitmaps.  Ignore error<y>?

/dev/ad1s1: e2fsck canceled.
