I was expecting it to return ext3 but the output is something unexpected. I have no idea what to try with this. Did you perform mkfs anytime after removing it from LV? Not sure how can ext3 fs can turn into DOS. I have tried file command on my RHEL 6 and the output shows me the file system with which it is formatted. May be because F10 is quite old file command not showing the correct output but cannot for sure.
I was expecting anything else but DOS. As I told, I've tried to find a file system in this disk with e.g. Testdisk. I wonder if it can cause something like this. Otherwise I have refused to write on this disk with any program other than Gparted. I have written an LVM flag sometimes on the disk, just because I had no other idea.
I am out of ideas for now, I am away from my test system and cannot say for sure what you could try. The message:
Code:
mount: wrong fs type, bad option, bad superblock on /dev/mapper/VolGroup00-LogVol02,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
I got yesterday during testing but that was because I have done vgcfgrestore incorrectly. Once I figured it out it went fine. I would suggest you to recheck the steps that you have performed so far.

Another thing you can try to see if you get more information is:
Don't worry, you have also helped me a lot! I will check my commands.
That file command returned:
/dev/sdb1: LVM2 (Linux Logical Volume Manager) , UUID: sb4SLylaOqJGaXzctrmtkJ9Zfb23gPU
The graphical LVM interface allows me to edit the properties of a Logical Volume. It also shows that this volume has no file system. I can select the file system and choose it to be mounted and/or mounted at boot and name the mount point. I suppose this edit would format the disk again and edit fstab? I cannot be sure if I have anything left on this disk, but this would make sure there isn't anything. I will not do it.
Also, let's see the contents of /etc/lvm/backup/VolGroup00. Hopefully, it matches the archived metadata that you posted earlier. [EDIT] That's aside from differences in device names.
Another bit of useful information would be the output from
I studied a little the graphical interface of LVM. The physical view shows this SATA disk has 59616 total physical extents. Then there is a choice available to Migrate Selected Extent(s) From Volume. What does that do?
I afraid I need to remove this SATA disk again from the LVM to be able to boot next time. It is already late here. I gather we can get to this same state easily now?
