Hi, for my previous system I used LVM and was very satisfied with it. Therefore I wanted to use LVM again for my new system (after a reiserfs crash on the root partition). There was one volume group "system2" consisting of 6 PVs and one LV (dev/system2/common) (dev/system2/common survived the crash unharmed). I was on the way to install a new system (SuSE 7.3) and gave with Yast2 commands to add and format another PV (/dev/hdb4) and add two more LV. I do not know exactly what happened, but YaST showed me an error that one of the LVM commands did not succeed (IIRC the problem was that creating another LV was not possible beause of missing disk space which sounded absurd to me since there were >30GB free) but anyway... I canceled the action and when I was back in the LVM screen my VG "system2" did not exist anymore :-( I have no lvmconf etc. :-( Is it possible to recover the VG from the data of the PVs?

I read parts of the German and English HowTo's and also searched google and the archive of this mailing list for help. I found the thread "VG lost, no lvmconf => Help !" but I am not sure if this helps me since I checked all PV UUID seem to be o.k. Probably I need UUID fixer to get my system back, but I am not sure if 20.1 of the HowTo is what I am looking for.
