-Winhex 12.5 I'm attempting to browse a linux LVM 2 partition which contains an ext3 and swap. The partition is read as unknown, but I would like to beable to browse files with the file browser. Now I know the long way to do so is copy the entire partition to a file then delete the LVM so that winhex reads the ext3. I know what sector my ext3 starts on that partition so is there some template or something so I wouldn't have to copy the entire partition and delete the LVM preceding the ext3. By the way winhex is an excellent program and would be great if there was a similar program for linux. | ||

Now I did that and winhex picked up a "5.3 gb ext3 (del)" partition 5; It doesn't look like it's reading it correctly. The ext3 partition is actually 40gb or so and isn't deleted. When opening partition 5 i get a message like partition 5 is not readily accessible and the side pane - properties- tell me there is 8.9 GB used (correct) 33.8GB free (correct) but only 5.3GB total (not correct). As a result the file browser doesn't display all files. I attempted to change the disc parameters- enlarging it but I get stranged errors like "cannot read from sector ... of floppy disc -1 cannot find specified file" Any suggestions? | ||

> WinHex usually reads the size of the partition from the superblock. I found out that this was not done correctly for Ext2/Ext3. Will be fixed shortly with WinHex 12.6! | ||

Hi! I found this old thread while searching for ways to get data out of an LVM1 volume. Unless the starting sector of a partition within an LVM volume is known, the only way to access the data seems to be recovering the LVM using Linux, and making a dd clone of the contents. (See http://www.linuxjournal.com/article/8874 for instructions on how to do this.) This approach works, but it requires quite a lot of extra work. Stefan, could you consider adding support for LVM 1 and 2 to some upcoming version of WinHex? In theory LVM should be rather easy to parse. This feature would make life with LVM volumes a lot easier.

A colleague has an E01 image of a physical disk on which Linux partitions are managed by LVM2. (I haven't received the image yet.) I know very little about Linux and less about LVM. Basically, we want file system access. I don't expect a course on LVM, but will XWF simply mount the partitions or must I do some recovery of the LVM managed partitions before proceeding. Perhaps booting the image in a VM and imaging from there. Thanks. | ||

I wonder if anyone can help me find detailed information about the LVM descriptor sector. Magic No: 0x4D48 (HM) Thanks in advance, Mike | ||

hi friends I have a problem .. actually I m working on LVM in linux through WinHex ..I have made one volume group and it has two logical volumes logvol00 and logvol01 and both are respectively mount on /rahul and /rock..I have found both folder(rahul & rock) in root directory which use ext file system but I m unable to reach data of rahul and rock folder.But through searching WinHex I got that data LVM partition..Actually the main is that is there any structure of LVM so that i can find my data like file system(ext and more).second problem is that after extending the volume group by other hard disk I m unable to decipher connectivity b/w data from one to other hard disk..plz help me... |
