raid installs are failing with edge

[Michael Hudson-Doyle]

Raid installs fail at the "configure mdadm" step. I'm not sure when this started, or whether it's eoan specific (about to test this last part). The raid1 tests are still passing with stable though.

[Michael Hudson-Doyle (mwhudson)]

Happens with a disco based ISO too. It's just a guess but I think it might be the change to bind mount /run that does this?

[Michael Hudson-Doyle (mwhudson)]

Yeah, if I skip the step that bind mounts /run into /target, RAID works again. Sigh.

I think this is arguably a curtin bug: it doesn't disable daemons in the target while reconfiguring mdadm. Should be easy enough to test that theory, will report back in a bit.

It actually does disable daemons. See ChrootableTarget.

The check in the post script still will exec systemctl commands. Can we get
a debug log of the failure to confirm?

It would disable daemons _if it used ChrootableTarget_. MP incoming.

Let's definitely get the logs.

The restart code in postinst has been around since 2014. So that's unlikely to be the cause, though the presence of /run does trigger something that wasn't ever tested before.

This bug was fixed in the package mdadm - 4.1-2ubuntu2

---------------
mdadm (4.1-2ubuntu2) eoan; urgency=medium

  * Drop broken and unused init scripts in favor of native systemd units,
    which can cause failure to reconfigure mdadm package under certain
    confiment types. LP: #1829325

This bug is believed to be fixed in curtin in version 19.2. If this is still a problem for you, please make a comment and set the state back to New

Thank you.
