Now I've took my time to gather all the info I could (and it wasn't that easy to calculate the offsets, I have nilfs2 on an LVM volume on a GPT disk:), LVM partition offset is 34816 sectors, 1st PE is 384 sectors inside the partition, the NILFS volume starts on the 256th PE) This command produced error messages so I think the offset is right: sudo dd if=/dev/mapper/emmc--lvm-rootfs of=rawdump_2713.bin bs=$((4096*2048)) count=1 skip=2713 [ 5142.730071] mmcblk0: retrying using single block read [ 5145.599122] mmcblk0: error -110 transferring data, sector 46594382, nr 434, card status 0x200900 [ 5145.624308] end_request: I/O error, dev mmcblk0, sector 46594382 [ 5148.442955] mmcblk0: error -110 transferring data, sector 46594383, nr 433, card status 0x200900 [ 5148.467911] end_request: I/O error, dev mmcblk0, sector 46594383 [ 5148.489628] Buffer I/O error on device dm-0, logical block 5557753 [ 5151.436927] mmcblk0: error -110 transferring data, sector 46594574, nr 242, card status 0x200900 [ 5151.462374] end_request: I/O error, dev mmcblk0, sector 46594574 [ 5154.286162] mmcblk0: error -110 transferring data, sector 46594575, nr 241, card status 0x200900 [ 5154.311555] end_request: I/O error, dev mmcblk0, sector 46594575 [ 5154.333388] Buffer I/O error on device dm-0, logical block 5557777 Attaching dumpseg output for segment 2713, strace for nilfs_cleanerd, etc, HTH.
