It's RAID0, which I *believe* can't get out of sync, but there is much I do not understand about RAID. > Can you take the two .gz files and reconstruct a file system on some > other system with a known-bug disk, and then try running e2fsck on the > the image? e2fsck successfully repairs both the skeleton image and the complete partition image when they are on a known-good disk. Here's some more detail about the partition. The "Partition does not start on physical sector boundary" thing might be relevant. (I can't say I understand how that can even happen, though.) md127 : active raid0 sde3[1] sdd3[0] 556720128 blocks super 1.2 512k chunks # sfdisk -Vl /dev/md127 Disk /dev/md127: 531 GiB, 570081411072 bytes, 1113440256 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 524288 bytes / 1048576 bytes Disklabel type: dos Disk identifier: 0x2c9d8483 Device Boot Start End Sectors Size Id Type /dev/md127p1 63 128005919 128005857 61G 83 Linux /dev/md127p2 128005920 1113433019 985427100 469.9G 83 Linux Partition 1 does not start on physical sector boundary.
