this script attempts to do the following for img=working.img device=/dev/working0 img=broken.img device='/dev/broken 0' - create a file $img - partition it with sfdisk - losetup a device pointing to $img - kpartx -a -v -p -part $LODEV
run the script and you can see, it will work for 'working0' and fail for 'broken 0' $ sudo ./show === img=working.img devname=/dev/working0 lodev=/dev/loop1 === add map working0-part1 (252:0): 0 202752 linear /dev/working0 2048 === 0 == brw-rw---- 3 root disk 7, 1 Jun 3 20:46 /dev/working0 === img=broken.img devname=/dev/broken 0 lodev=/dev/loop0 === device-mapper: reload ioctl on broken\x200-part1 failed: Invalid argument create/reload failed on broken 0-part1 add map broken 0-part1 (0:0): 0 202752 linear /dev/broken 0 2048 === 1 == brw-rw---- 2 root disk 7, 0 Jun 3 20:46 /dev/broken 0 failed kpartx to /dev/broken 0 that is basically the same way the multipath-boot setup fails. ** Attachment added: "show-kpartx-bug" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1371634/+attachment/4409447/+files/show-kpartx-bug -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1371634 Title: block devices appear twice To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/curtin/+bug/1371634/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
