Hi

I need your advice in the process to restore the data of a LV from a mess

I remove a PV from a GV on a umounted system and then I lost the whole group, now I just have the first HD and I want to read the data it has

Thanks

Octavio

I'm not an expert of this area and not sure if you can rescue it or not,
but the following document might be helpful to you.

Chapter 6. LVM Troubleshooting
http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.5/html/Logical_Volume_Manager_Administration/troubleshooting.html

6.4. Recovering Physical Volume Metadata

Thanks,

Hello Taka

That's the good news, and thank you for the explanation about the way
how you recovered it.

Thanks,
