Package: kpartx Version: 0.6.4-5+b1 Severity: normal Dear maintainer,
There is a problem with the current version of kpartx in Debian, which is probably fixed upstream by commit 6ff376d43cadf934447, released in version 0.7.2. Having inserted the 'loop' module with option max_part=8 (modprobe loop max_part=8), a simple invocation of vmdeboostrap (1.8-1) to create a disk image with one partition fails because of kpartx: # vmdebootstrap --verbose --image=vmd1 --size=1G --arch=i386 --grub Creating disk image Creating partitions EEEK! Something bad happened... command failed: ['kpartx', '-avs', 'vmd1'] [...] indeed, the kernel already created loop1p1, and kpartx is confused by this situation, as it identifies that loop1p1 is the loop device attached to vmd1, instead of loop1: # kpartx -avs vmd1 device-mapper: reload ioctl on loop1p1p1 failed: Device or resource busy create/reload failed on loop1p1p1 # kpartx -l vmd1 loop1p1p1 : 0 1949693 /dev/loop1p1 3 Not using the loop's max_part option can workaround the issue. The upstream commit will probably cause kpartx to identify loop1 as the correct loop device and overwrite loop1p1, working around the problem. -- System Information: Debian Release: buster/sid APT prefers oldoldstable APT policy: (500, 'oldoldstable'), (500, 'unstable'), (500, 'oldstable'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.14.0-1-amd64 (SMP w/2 CPU cores) Locale: LANG=fr_FR.UTF-8, LC_CTYPE=fr_FR.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to fr_FR.UTF-8), LANGUAGE=fr_FR.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to fr_FR.UTF-8) Shell: /bin/sh linked to /bin/dash Init: sysvinit (via /sbin/init) Versions of packages kpartx depends on: ii dmsetup 2:1.02.145-4.1 ii libc6 2.25-5 ii libdevmapper1.02.1 2:1.02.145-4.1 ii udev 236-1 kpartx recommends no packages. kpartx suggests no packages. -- no debconf information
