kpartx fails to map partitions (device-mapper: resume ioctl failed: Invalid argument)

[Malte S. Stretz]

Binary package hint: multipath-tools

Under certain conditions kpartx fails to map partitions. You can try it with the image available here <http://m0n0.ch/wall/download.php?file=generic-pc-1.32.img>:

It seems like this is debian bug 586104 and fixed in newer versions of multipath-tools.

I've got to correct myself: This is fixed by a Debian patch which is available here <http://git.debian.org/?p=pkg-lvm/multipath-tools.git;a=patch;h=858f733> (I haven't tried it though).

[Serge Hallyn (serge-hallyn)]

The patch listed in comment #2 is applied in precise and quantal, so the bug should be fixed. (The sample .img file in the description is also no longer available.)

Marking this 'fix released'. Please feel free to re-open if you can reproduce this bug.

[Malte S. Stretz (mss)]

Looks like this is still an issue in Precise (see below). You can find the most recent version of that image at http://m0n0.ch/wall/downloads.php (get the generic-pc-1.33.img). I can't judge about Quantal.

The Precise Pangolin has reached end of life, so this bug will not be fixed for that release
