Description of problem: qemu-nbd dies when trying to e.g. copy an entire filesystem off an LVM partition inside a disk image. This bug has been reported before against previous Fedora releases, and closed when they got EOLed, but what's new here is (a) this is on the latest Fedora, and (b) a reproducable test case. Version-Release number of selected component (if applicable): qemu-common-0.15.1-3.fc16.x86_64 How reproducible: Always Steps to Reproduce: 0. Obtain or create some Linux disk image, which below I've called rawhide.img because it contains a rawhide image 1. modprobe nbd max-part=63 2. qemu-nbd -t -v -c /dev/nbd0 rawhide.img Open a new terminal 3. vgchange -ay 4. mkdir /mnt/rawhide 5. mount -o noatime /dev/mapper/vg-lv_root /mnt/rawhide/ 6. /bin/cp -af /mnt/rawhide . Actual results: after about a minute: ... lots of lines like /bin/cp: `/mnt/rawhide': Input/output error and in the qemu-nbd terminal: connect(unix:/var/lock/qemu-nbd-nbd0): No such file or directory NBD device /dev/nbd0 is now connected to file rawhide.img nbd.c:nbd_receive_request():L460: read failed Expected results: No qemu-nbd crash

This message is a reminder that Fedora 16 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 16. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '16'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 16's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 16 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Hi Robin, sorry this never got a response. Since F16 is going unsupported, closing as WONTFIX. If you can still reproduce against F18, please reopen. Thankfully though qemu-nbd went from barely maintained to very actively maintained between F16 and F18 qemu versions, so things should be better these days.
