Hi Richard,
Thought that this may be useful for people using G4U and have a need to
access files from a ghost image without having to restore the entire
image to a disk.
It is recommend that you have a recent Linux distro I used the latest
Ubuntu
as this has the latest fdisk and GNU file tools that support large
files. Knoppix or
other new distros should work just as well.
Mount the file share where you have stored your images.
I used NFS as SMB seems to have a max file-size limit of 2Gb on file-
share I was
using.
# mount -t nfs 192.168.51.13 /mnt/nfs
Uncompress the image but as a sparse file i.e. don't create the empty
space on the file-share server.
# gunzip -dc test_t43p.gz | cp --sparse=always /dev/stdin test_t43_outo
Next you need to find the partition offset's that are inside your
image as you
cannot mount the image file directly as the first blocks contain the
boot records and
other data.
# fdisk -l -u -C 592 <image_name>
Disk testo_t43_outo: 0 MB, 0 bytes
240 heads, 63 sectors/track, 592 cylinders, total 0 sectors
Units = sectors of 1 * 512 = 512 bytes
Device Boot Start End Blocks Id System
testo_t43_outo1 * 63 108939599 54469768+ 7 HPFS/NTFS
Partition 1 has different physical/logical endings:
phys=(1023, 239, 63) logical=(7204, 239, 63)
testo_t43_outo2 108939600 117210239 4135320 12 Compaq
diagnostics
Partition 2 has different physical/logical beginnings (non-Linux?):
phys=(1023, 0, 1) logical=(7205, 0, 1)
Partition 2 has different physical/logical endings:
phys=(1023, 239, 63) logical=(7751, 239, 63)
Multiply the start cylinder by 512 to get the offset in this case 32256
# mount -t ntfs -o loop,offset=32256,ro <image_name> /mnt/loop
Change the filesystem type if the disk is not NTFS i.e. EXT3 for Linux.

You now have access to all the files in the image.

1st Off, I love this program.
2nd, I am just about to wipe a server, but I want to insure I can
pull the contents of the drive image in case I may need them in the
future (I don't plan to, but just in case)
Anyway, I have created an image of the server on one of my FTP
servers, I then gunzip'd the file and get the image of the drive
(its huge)
Now, I am trying to mout the image on a centos box so if needed, I
could pull files off of the image.
Right now I am stuck at mounting the image, here is a little bit of
what I have tried
# mount -o loop /home/richard/image/r1-ww-db_image /root/temp/
mount: you must specify the filesystem type
Fine, I do:
# file r1-ww-db_image
r1-ww-db_image: x86 boot sector
Cool ... now what do I put for the filesystem type?
What I am imaging is a OpenBSD router we no longer need to use, and
we have plans for the hardware. But just in case I need some config
file, I want to make sure I can get it before wiping the drives.
Thoughts?
Sorry for the stupid questions, I am a bit of a newby but catching
on fast.
