Hello again I've just run e2image, as you suggested and it doesn't look like it's ever going to complete. There are lots of errors on the console like: Illegal block number passed to ext2fs_mark_block_bitmap #822751537 for in-use block map Illegal block number passed to ext2fs_mark_block_bitmap #825307441 for in-use block map Illegal block number passed to ext2fs_mark_block_bitmap #825307441 for in-use block map Illegal block number passed to ext2fs_mark_block_bitmap #825307441 for in-use block map Illegal block number passed to ext2fs_mark_block_bitmap #170996017 for in-use block map Illegal block number passed to ext2fs_mark_block_bitmap #825307441 for in-use block map Illegal block number passed to ext2fs_mark_block_bitmap #825307441 for in-use block map Illegal block number passed to ext2fs_mark_block_bitmap #825307441 for in-use block map Illegal block number passed to ext2fs_mark_block_bitmap #825307441 for in-use block map Illegal block number passed to ext2fs_mark_block_bitmap #825307402 for in-use block map Illegal block number passed to ext2fs_mark_block_bitmap #825307441 for in-use block map Is this something I need to leave running for a long time? I tried it on the other problematic LV and the command did complete, though the qcow2 file it produced was empty.
