That should have not given you any superblock output if it were the partition for the logical volume /dev/VolGroup00/LogVol01
The output would had been more in the order of:
/dev/sde2 is apparently in use by the system, blah, blah
even if it is broken
Question? Are you sure that /dev/sde2 is the partition of the LVM?
Either of those two would output the proper superblocks if available, assuming for sure that /dev/dm-1 maps to the LVM.
What's the output of lsblk if available?
What's the output of pvdisplay?

Reason: asking for pvdisplay
Here is a very interesting article on not only hiding data on filesystems (the article deals mainly with the ext2 filesystem, which should also work with etx3), but also recovering, including from slack space on raw blocks, and even deleted data!

Hello,
Is there a way to recover data from a SCO UNIXWARE 7.4 operating system without using a tape backup device?
We believe there is some data in some directories that was there once; but not anymore, we don't have a backup on tape.
So, is there any other solution to recover?
Hope... (0 Replies)
Hey peeps,
Here is somethin u might find interestin....
Is it possible to recover data from a partition which used to be an ext3 file sytem with some nice forgotten backups, which now is an lvm partion containg root partition of another OS. :)

Not real Linux expert but here is the problem.
Shutdown this machine and then it would not reboot.
From everything I can tell it looks like the journal file in the logical volume is corrupted. I have tried everything I can think of to get the volume mounted.
Anybody have any ideas on how... (19 Replies)
Hi,
I'm new to HP-UX.
I have LVM on /var with 92Gig. I would like to reduce it to create another LVM for Oracle client with 800 meg or so. How to do it. I'm running 11.iv3

I have a flash drive which contained very important docs. But somebidy accidently dleted those files. I want to recover these files anyhow.
I have listened the Linux have best possible chances of recovering it.
Can anybody tell me how to recover that? (1 Reply)
Hello friends,
We had to upgrade RHEL 4.x to 5.7 so we took complete backup. Since DIRECT UPGRADE not possible, we rebuilt 5.7 from scratch.
We had lvm configuration on DATA disks in previous OS and now we need to configure such that we should be able to have same old LVM configuration (like... (1 Reply)
I have a Sun sparc classic that I am trying to recover data off. The main CPU part just clicks or beeps when powered up, but does not come on (nothing on screen, and LED in front not lighting up).
There is also an external SCSI drive, and I have verified there is a drive inside the CPU.

dumpe2fs
DUMPE2FS(8) System Manager's Manual DUMPE2FS(8)NAME
dumpe2fs - dump ext2/ext3/ext4 filesystem information
SYNOPSIS
dumpe2fs [ -bfhixV ] [ -o superblock=superblock ] [ -o blocksize=blocksize ] device
DESCRIPTION
dumpe2fs prints the super block and blocks group information for the filesystem present on device.
dumpe2fs is similar to Berkeley's dumpfs program for the BSD Fast File System.
OPTIONS -b print the blocks which are reserved as bad in the filesystem.
-o superblock=superblock
use the block superblock when examining the filesystem. This option is not usually needed except by a filesystem wizard who is
examining the remains of a very badly corrupted filesystem.
-o blocksize=blocksize
use blocks of blocksize bytes when examining the filesystem. This option is not usually needed except by a filesystem wizard who is
examining the remains of a very badly corrupted filesystem.
-f force dumpe2fs to display a filesystem even though it may have some filesystem feature flags which dumpe2fs may not understand (and
which can cause some of dumpe2fs's display to be suspect).
-h only display the superblock information and not any of the block group descriptor detail information.
-i display the filesystem data from an image file created by e2image, using device as the pathname to the image file.
-x print the detailed group information block numbers in hexadecimal format
-V print the version number of dumpe2fs and exit.
BUGS
You need to know the physical filesystem structure to understand the output.
