I have nowhere near enough extra space to hold the image and tar file you've asked for AND, there's too much personal information for me for me to feel comfortable posting it publicly. Understood. e2image doesn't have a filename scrubber like the btrfs-image equivalent (-s and -ss). I don't have a good work around for this, and suggest asking on the ext4 development list. > I'm converting a smaller drive now and see an error message "1234 [ 3341.845090] sdb: p1 size 1465144002 extends beyond EOD, enabling native capacity". Do you think this will cause the error condition from scrub that "we" are looking for?
