BTW, I'd like to mention I tested/exercised both multipath-tools (kpartx) and
parted (libparted) patches by verifying both the already-existing partitions
(kpartx) and creating new partitions (libparted) cases.
The partitions devmaps had correct number of sectors in both cases.

Hello,
We can consider the new new package (local version ubuntu7.4) already

You're testing w/ multipath-tools from -proposed?
If that's the case and the disk is already partitioned, I expect it to
work, as kpartx is patched and will use the right offsets for dmsetup.
If the disk is not partioned, thus partitioned w/ parted, then kpartx

Testing this on Trusty (and for some reason, my overlay not working), it

removal of _dm_resize_partition changes, as this function doesnt exist on

Back to comment #5.
If it's possible to install LVM on top of multipath, then I think the problem
shall happen too, because then the first level of mapping is multipath on top
of the underlying devices (4k sectors).

BTW, but not too important:
There's a quite repetitive verbose output during update-grub, mentioning:
ERROR: unsupported sector size 4096 on .
It happens because os-prober calls dmraid for every partition, but it doesn't
support 4k sectors, and yields to stderr.
A simple redirect quiets it up.
Description fixed.

I incorrectly mentioned LVM was also affected by the issue.
It doesn't, as the dm mappings are the LVs mapped on top of VGs, which already
take sectors as 512B AFAICT.
The issue arises w/ multipath because then the partitions are mapped directly
on top of the underlying devices, which have 4k se
