如何修复“磁盘/ dev / mapper / VolGroup不包含有效的分区表”
[root@localhost _work]# fdisk -l Disk /dev/sda: 160.0 GB, 160041885696 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x13159c87 Device Boot Start End Blocks Id System /dev/sda1 * 1 64 512000 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 64 19458 155777024 8e Linux LVM Disk /dev/mapper/VolGroup-lv_root: 156.8 GB, 156766306304 bytes 255 heads, 63 sectors/track, 19059 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/mapper/VolGroup-lv_root doesn't contain a valid partition table Disk /dev/mapper/VolGroup-lv_swap: 2113 MB, 2113929216 bytes 255 heads, 63 sectors/track, 257 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/mapper/VolGroup-lv_swap doesn't contain a valid partition table 你不修复它。 它不应该有一个有效的分区表，文件系统直接在块设备上。 这是一个逻辑卷。 只要忽略fdisk抱怨不是磁盘的设备。
对于任何/dev/mapper设备， fdisk -l命令输出几乎完全没有价值。
