Code:
loading initial ramdisk...
I added all_generic_ide at the end of linux line and also added dev/sda1 to linux line: root=UUID=dev/sda1
now it says that
I have checked from the first kernel with df -h, it says that my main drive which is the root file system is /dev/sda1.
so! what's the problem?
Does anyone know if there is free software that can keep 2 filesystem on remote machines , synced.
This will be part of our Disaster Recovery to keep one machine off site , which will take over should the need arise..

Hi all,
I tried setting up RAID between 2 partitions and it was success.
If I write some things on /dev/md0, both partition got affected.
Then I stop the RAID, and I mounted one of my partition and I created a file in it.
Now I started the RAID (mdadm --assemble --scan)

o2image
o2image(8) OCFS2 Manual Pages o2image(8)NAME
o2image - Copy or restore OCFS2 file system meta-data
SYNOPSIS
o2image [-r] [-I] device image-file
DESCRIPTION
o2image copies the OCFS2 file system meta-data from the device to the specified image-file. This image file contains the file system
skeleton that includes the inodes, directory names and file names. It does not include any file data.
This image file can be useful to debug certain problems that are not reproducible otherwise. Like on-disk corruptions. It could also be
used to analyse the file system layout in an aging file system with an eye towards improving performance.
As the image-file contains a copy of all the meta-data blocks, it can be a large file. By default, it is created in a packed format, in
which all meta-data blocks are written back-to-back. With the -r option, the user could choose to have the file in the raw (or sparse) for-
mat, in which the blocks are written to the same offset as they are on the device.
debugfs.ocfs2 understands both formats.
o2image also has the option, -I, to restore the meta-data from the image file onto the device. This option will rarely be useful to end-
users and has been written specifically for developers and testers.
OPTIONS -r Copies the meta-data to the image-file in the raw format. Use this option only if the destination file system supports sparse files.
If unsure, do not use this option and let the tool create the image-file in the packed format.
-I Restores meta-data from the image-file onto the device. CAUTION: This option could corrupt the file system.
-i Interactive mode - before writing out the image file print it's size and ask whether to proceed. This setting only applies when '-I'
is not specified. It can be useful when the file system holding the image is low on disk space and the user might need to free up
space once the target image size is calculated.
EXAMPLES
[root@node1 ~]# o2image /dev/sda1 sda1.out
Copies metadata blocks from /dev/sda1 device to sda1.out file
[root@node1 ~] o2image -I /dev/sda1 sda1.out
Use with CAUTION. Copies meta-data blocks from sda1.out onto the
/dev/sda1 device.
