[CentOS] Problem after last update

Hi all,

i've just updated CentOS4.3 .
After updating it i rebooted the machine (cause there was some kernel
pkg's) and it seems that centos lost my LVM config ....
I tried manually a vgscan and:
(root at backupsrv) boot # vgscan
  connect() failed on local socket: Connection refused
  Locking type 2 initialisation failed.

and my /dev/VG0/LogVol00 dissapeared :-(



Any tips ?
