Recently I update a server running CentOS 4.3 to kernel 2.6.9-42.0.2. After the update it had a problem to mount LVM partitions, showing the follow error during boot: No volume groups found Activating logical volumes Unable to find volume group "lvm1" ERROR: /bin/lvm exited abnormally! (pid 199) Creating root device Mounting root filesystem mount: error 6 mounting ext3 mount: error 2 mounting none Switching to new root switchroot: mount failed: 22 umount /initrd/dev failed: 2 Kernel panic - not syncing: Attempted to kill init! Root partition is a LVM2 on Software RAID. With old kernel (2.6.9-34.0.2) the system boot normally. Any idea what is error? Best regards Heitor Augusto
