rescue a lvm
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

Hello Taka
