Alright, I have it running, here's the short version, commands only, no
output, run as root, disk is attached at /dev/sdf with one partition:<br>
<br>
<br>
Check the filesystem (might want to use -f to force a real check)<br>
# fsck /dev/sdf1<br>
<br>
Repartition with sfdisk, start at the first cylinder end at the last<br>
# echo ",,L" | sfdisk /dev/sdf<br>
<br>
Resize the ext3 filesystem<br>
# resize2fs /dev/sdf1<br>
<br>
Recheck the filesystem<br>
# fsck -f /dev/sdf1 <br>
<br>
Now mount and check that the data is there and the size is correct with
df -h.<br>
<br>
Let me know if it works for you.<br>

Even on ubuntu, even with my original volume, you can't do "e2fsck" of
the "device" , e.g. <br>
<br>
$ e2fsck /dev/sdz<br>
Couldn't find ext2 superblock, trying backup blocks...<br>
e2fsck: Bad magic number in super-block while trying to open /dev/sdo<br>
...<br>
<br>
Is that to be expected? In a number of tutorials on resizing EBS
volumes, i have seen this done with the devices itself. Is the reason
this is failing because its a partitioned drive? <br>
