[linux-lvm] Fedora lvm PV lost ! Need to recover data

[NGUYEN, Laurent (Elite)]

Hello,

We have lost the physical volume /dev/hda4 since a reboot of Fedora.

/dev/hda4 had lots of data on a logicial volume and we know the data is
still on /dev/hda4. Data was on /dev/Volume01/LogVol00  

/dev/hda2 has no problem (still on dev/Volume00/LogVol00).

 

 

 

Here is information about my system :

 

[root at localhost lvmconf]# uname -a

[root at localhost lvmconf]# pvscan

pvscan -- reading all physical volumes (this may take a while...)
