[linux-lvm] Recovery of data in LVM from a corrupt disk

[Hale India]

Hi Andy
 
 Nice news. Last time when I post my problems I got no answers.
 
 If you can describe how to proceed when you need to move your hardisks to another machine (In my case the cause when hardware failure of mother board) and when boot disk doesnot accept to boot on the new machine (in my case it was fedora 4 and probably some difference of hardware. The only way I solved was to install disks in the exactly same machine)

 If you can give to us some guideline it would probably save some situations.
 If you can point us to documentation in LVM project usefull for such case it would even be better.
 
 Best regards

If my machines crash often enough that I am regularly juggling disks
I consider this a problem beyond the scope of LVM (unless they're
crashing in LVM).

Anytime I *have* had to move LVM setups to other machines I have had
no issues.

I'm confused why you continually compare LVM to various filesystems
when it isn't a filesystem.  It has different challenges and use
cases.

If you could go into more detail regarding incidents where you have
lost data on otherwise working disks then perhaps you could get more
help.
