I have VMPlayer 12 running a CentOS 7 disk. Works fine. However I wish to change the disk from UUID booting (fstab) to the old style LABEL. (so I can export it and use on another machine). fdisk -l /dev/sda Disk /dev/sda: 21.5 GB, 21474836480 bytes, 41943040 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk label type: dos Disk identifier: 0x0001c6d3 Device Boot Start End Blocks Id System /dev/sda1 * 2048 20482047 10240000 83 Linux /dev/sda2 20482048 22530047 1024000 82 Linux swap / Solaris /dev/sda3 22530048 41943039 9706496 83 Linux however when I run: e2label /dev/sda1 / e2label: Bad magic number in super-block while trying to open /dev/sda1 Couldn't find valid filesystem superblock. Three questions: 1) Am I doing something wrong? 2) Is there a better way? 3) How do I support VM formats (VBox, VHD and VMWare) easily?
