[Bug 1635049] Re: Boot fails with degraded mdadm raid

[Kevin Lyda]

This did not work but I'm not clear why. It might have been be messing
up the grub install.

[Bug 1635049] Re: Boot fails with degraded mdadm raid

[Kevin Lyda]

Hey there kids, this bug still appears to be relevant for 16.04. My
/dev/sda died today and I'm prepping to replace the disk. I note that
the answer here https://askubuntu.com/a/798213/185653 notes the missing
file and it's still missing.

I haven't tried a reboot as I'm waiting for the monthly check to
complete on the other array but I've added in that script and rebuilt my
initramfs and installed grub on sdb. Will let folks know how I get on.

The tone and comments in this bug from some reporters and others is...
poor. I would have hoped for better.

Is this bug report abandoned?

And why the bug is assigned to Dimitri John Ledkov? He is obviously
incompetent. In comment number 18 he even claimed that photographs and
screenshots aren't acceptable in bug reports even though Ubuntu's
website clearly states otherwise.

[Bug 1635049] Re: Boot fails with degraded mdadm raid

[Rüdiger Schernthaner]

It seems that this is still somehow broken with Xubuntu 17.04

I just tried mdadm within Xubuntu 17.04 in Virtualbox using the following setup:
1 virtual disk containing the OS.
2 virtual disks running as a RAID 1.
Whenever I disconnect one of the RAID disks, Xubuntu cannot boot.

I wrote the script shown here:
https://askubuntu.com/questions/789953/how-to-enable-degraded-raid1-boot-in-16-04lts
to the file /usr/share/initramfs-tools/scripts/local-top/mdadm
After that, Xubuntu can boot properly with the degraded RAID.

Is this the intended behaviour?
Thanks

And this is a perfect example why Ubuntu is a piece of garbage. Someone
reports a serious issue with Ubuntu, but the whole bug gets dismissed,
because the reports are in a "wrong" format.

How do you even get early boot logs out of Ubuntu when the boot fails?
You didn't even mention that.

Is there some way to contact professionals at Canonical instead of these
amateur wise asses on this platform?

Why do you lie? You didn't even look what I reported?

The first screenshot clearly shows that the boot fails before password is even 
asked.
The second screenshot shows that the password is asked when I attached the 
drive again.

I've submitted a bug report regarding this to Ubuntu and Debian, but
nobody seems to care. It's 2017 and RAID 1 doesn't work...

Please open new a new bug report, instead of piling onto an unrelated
report.

And your boot is waiting for you to unlock the encrypted volume...
only after which the volume groups will be detected.

I do not see anything degraded in your case at all.

Note your test-case is completely different to this bug report as it
also involves encrypted volume.

Dimitri.

- Fix UUID= grep for configured RAIDs to be case insensitive.
- Drop CREATE stanzas from mkconf and don't include them in the

I can do that. However, I am not sure if that is necessary since this is a
sync from bileti ppa, and thus it is identical binaries.

Hi Lukasz and Dragan,  I just received confirmation from a customer that
the propsed package also fixed the issue on their ibm power environment
as well.

This was using the ca-train-ppa-service ppa however, so I'll check again
using the proper proposed repository package.

I accepted the package from the queue to -proposed but since it was a
sync I couldn't do it through the proper tooling (I think I need to get
educated how to do it properly for synces?). Anyway, this means that
there was no auto-release message. Please install the package from
xenial-proposed, test it and mark the bug as verification-done as with
any other SRU bug.

Thank you!

Will there be any backport patch for Ubuntu 16.04.2?

Just tested this out yesterday and Ubuntu 16.04.2 with latest update
still could not boot secondary drive.

My test was done on Linux mdadm RAID1 with LVM. (/dev/md0 for /boot xfs,
and /dev/md1 for LVM with /root xfs and swap).

Dimitri - Do you have any plans to get this fixed in Xenial?

This is fixed in 16.10 and Zesty, but I'm leaving the task open so the
