2950重启自动挂载逻辑卷时，物理卷，卷组，丢失？

小弟是2950的机器，分区信息如下：[root@iscsi-p1 /]# fdisk -lDisk /dev/sda: 1499.2 GB, 1499212021760 bytes255 heads, 63 sectors/track, 182268 cylindersUnits = cylinders of 16065 * 512 = 8225280 bytesDevice Boot Start End Blocks Id System/dev/sda1 * 1 19 152586 83 Linux/dev/sda2 20 176917 1420933185 83 Linux/dev/sda3 176918 179466 20474842+ 83 Linux/dev/sda4 179467 182268 22507065 5 Extended/dev/sda5 179467 180740 10233373+ 83 Linux/dev/sda6 180741 180994 2040223+ 82 Linux swap/dev/sda7 180995 182268 10233373+ 83 LinuxWARNING: GPT (GUID Partition Table) detected on '/dev/sdb'!
