Package: dmraid
Version: 1.0.0.rc16-12

Hello,

dmraid has an issue where kpartx is not run on boot.

This is due to the udev rule being triggered by DM_STATE, which is no
longer set. It used to be set by multipath-tools, but no longer does
since multipath-tools version 0.8.8-1[0].

What this means is that dmraid will work so you can see the block
device itself, but upon boot no partitions will be shown, and users
will have to manually run kpartx. This is the good case when the
partition is not the boot drive, if a user is using the latest
multipath-tools and dmraid for a boot drive, the partitions will not
be seen and fail to boot.

We can either reinstate the env file, or change the trigger. I'm
thinking about changing the trigger which looks like:

diff --git a/debian/dmraid.udev b/debian/dmraid.udev

dmraid is dead upstream and was removed from trixie. IIRC in the
bookworm release notes it was announced that bookworm will be the
last release supporting it.

It's not entirely gone from unstable yet, but I'll expect it to go
away completely sometime soon.

Best,
Chris

Sorry, was confused. It's already gone from unstable too.

Thanks Chris.

I haven't tested it yet, but I would imagine that bookworm is still
suffering from this issue, since multipath-tools is at 0.9.4-3+deb12u1.

I totally understand removing this project, but feel free to consider
making a patch such as this for users who are interested in the stable
release.

No worries if not - I'll look at patching this on the Ubuntu side since
there's some clear desire for it even if the upstream project is dead.

Hi all,

bookworm (the current stable) still has dmraid package. Combined with multipath-tools 0.9.4-3+deb12u1, it is broken: partitions are not mounted.
A one-line patch for the rules file may easily fix the this.

SID still has dmraid for riscv64. I am not sure whether it is some
leftover or intentional.
