In order to test my newly written mkaffs, I decided to create a 'filesystem' using the loopback device. This way nothing much could happen and it would be easy and fast to look at the result by just hex-dumping it. So I created an empty image with 'dd if=/dev/zero of=fs.img count=1760'. Attaching this to /dev/loop0 worked, but it wasn't usable: Dec 27 13:40:42 savong kernel: loop: block 513 not present Dec 27 13:40:42 savong kernel: end_request: I/O error, dev 07:00, sector 1027 Dec 27 13:40:42 savong kernel: loop: block 4 not present Dec 27 13:40:42 savong kernel: end_request: I/O error, dev 07:00, sector 8 Dec 27 13:40:42 savong kernel: loop: block 4 not present Dec 27 13:40:42 savong kernel: end_request: I/O error, dev 07:00, sector 9 [...] It seems as if the loopback device didn't like sparse files. When I took 1760 blocks from a non-empty file everything worked. Is this intended behaviour? jbhr | ||||||||||||
