[Bug 780668] New: loop block devices: Only /dev/loop0 usable if max_part parameter is used
https://bugzilla.novell.com/show_bug.cgi?id=780668 https://bugzilla.novell.com/show_bug.cgi?id=780668#c0 Summary: loop block devices: Only /dev/loop0 usable if max_part parameter is used Classification: openSUSE Product: openSUSE 12.2 Version: Final Platform: x86-64 OS/Version: openSUSE 12.2 Status: NEW Severity: Normal Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: Yarny@public-files.de QAContact: qa-bugs@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:15.0) Gecko/20100101 Firefox/15.0 If the loop kernel module gets loaded with a max_part parameter, only /dev/loop0 is usable, other loop devices cannot be attached to files. Reproducible: Always Steps to Reproduce: Make sure the loop module is not loaded already. Then: $ modprobe loop max_part=8 $ dd if=/dev/null of=/tmp/loopimg seek=1M $ losetup /dev/loop0 /tmp/loopimg # <-- OK $ losetup /dev/loop1 /tmp/loopimg # <-- Fails Actual Results: failed to setup loop device: No such device or address Expected Results: silent success I tested with a full openSUSE 12.2 installation from DVD (inside VirtualBox, hosted by 12.1, on x86_64). I don't know what the error message "No such device or address" refers to. The file and the (non-attached) loop device node both do exist. This is a regression, max_part didn't cause such trouble with openSUSE 12.1. I filed this under "kernel" since the max_part parameter seems to cause this bug, but it might be a bug in the loop userspace tool as well. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
