Hi , please have a look at /etc/sysconfig/lvm: LVM\_ACTIVATED\_ON\_DISCOVERED is probably still at the default value of “disabled” and you PV is not available at boot time. Does running “vgchange -ay VGncs” activate the VG, once the system has booted? What type of device is /dev/sdb - some SAN resource or DRBD device, activated after boot? Regards, Jens
