Thank you Jim, I'll try your suggestions; I'll let you now what will happen.

>  From me the amateur. You appear to have lost some data. You probably have some files that are recoverable. You have a few choices:

> 1) Send your disks to a professional. See http://myharddrivedied.com, for example.

> 2) Replace the electronics PC board on your drive. See the same above website for more info on that. This might recover all your data. It also may make no change.

> 3) Use dmsetup to enable a partial VG (use vgchange -Pay as explained in the article). See

> You can also remove the bad drive entirely and do a partial VG.

> 4) Use dd ignoring errors to do a raw copy off the bad drive to an identical good drive.
> Use vgcfgbackup. Remove the bad drive. Install the new drive.
