fsdb findblk does not do anything

[Artem Kuchin]

I tried to see how findblk command of fsdb works

So,i did

# cd /

# ls -li
       10 -rw-r-----   2 root  wheel         973 Jan 13  2015 .cshrc

So, we have  inode 10 for .cshrc

# istat /dev/ada2p3 10
inode: 10
Allocated
Group: 0
uid / gid: 0 / 0
mode: rrw-r-----
size: 973
num of links: 2

Inode Times:
Accessed:       2015-01-13 16:44:07 (MSK)
File Modified:  2015-01-13 16:44:07 (MSK)
Inode Modified: 2015-02-25 16:09:31 (MSK)

Direct Blocks:
5080

So,we have block5080 for this file. Letr try to find this inode by block 
number


# fsdb -r /dev/ada2p3
** /dev/ada2p3 (NO WRITE)
Examining file system `/dev/ada2p3'
Last Mounted on /
current inode: directory
I=2 MODE=40755 SIZE=512
         BTIME=Nov 12 00:03:46 2014 [0 nsec]
         MTIME=Mar 26 10:05:49 2020 [261484000 nsec]
         CTIME=Mar 26 10:05:49 2020 [261484000 nsec]
         ATIME=Dec 21 06:24:59 2014 [0 nsec]
OWNER=root GRP=wheel LINKCNT=21 FLAGS=0 BLKCNT=8 GEN=465e05d4
fsdb (inum: 2)> findblk 5080

fsdb (inum: 2)>

I waiting for long time but Nothing...

Why?
