You went from 200MB on the device to 194MB in the partition due to the
blocksize, I would guess.
You then lost more space when it was formatted as ext3 - the journal
consumes some of the space itself. You want this - running a journaled
filesystem like ext3 is much more reliable than running a journal-less one
like ext2.
The lost+found directory is where the system puts ownerless data blocks
during filesystem recovery after a system crash.
It's normal - everything is working as designed. You'll have to take these
overheads into account when you're sizing filesystems if you're really
tight on disk space.

hi list,
We have formated a mini disk of 285 Cylinders with :
dasdfmt -b 4096 -n 0104
dev00002:/mnt# less /proc/dasd/devices
0104(ECKD) at ( 94: 16) is dasde : active at blocksize: 4096, 51300
blocks, 200 MB
We have 200 MB
After the fdasd command we have made an ext3 file system with :
mke2fs -j /dev/dasd/0104/part1 -b 4096
When we mount this file system we have only 167MB free :
dev00002:/mnt# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/dasd/0100/part1 2.3G 811M 1.3G 37% /
/dev/dasd/0104/part1 194M 17M 167M 9% /mnt
Why we have lost 26 MB ?
What's the directory "lost+found" under /mnt ?
Thanks
Regards
