Description Morgan Leijström 2018-02-15 10:05:31 CET

Seen this for years, so no news, but good logs this time, i hope.
This bug probably share roots with Bug 22059, Bug 15262, and possibly more.

In short i installed Mageia 6, and during partitioning step i changed my mind, so removed and again added partitions.  After reboot i got 

 dracut Warning: Could not boot.
 dracut Warning: /dev/disk/by-uuid/ <long ID here>  does not exist

Recognising this problem, i ran the installer again, this time in the installer i simply reused all partitions, i just set the mount points (after having unlocked the encrypted LVM).  I think i chosed to format the disks just to be sure, and installed less packages (no Plasma) the second time. 

And i did grab logs :)
File from "bug" command after final step of install *both* times, and the rdsosreport.txt from the failed boot.

For clarity, this is the partitioning:

EFI Boot
/boot, ext4
Encrypted pv for LVM, containing
  /, ext4
  /home, ext4
  swap

Machine is acer Aspire 7, A717-71G, Disk is NVMe 256GB
Install and boot in UEFI mode with security turned off, quirk details in

Is this still valid in Mageia

Comment 6 Aurelien Oudelet 2020-08-16 16:09:37 CEST

Mageia 6 changed to end-of-life (EOL) status on 2019-09-30. It is no longer 
maintained, which means that it will not receive any further security or bug 
fix updates.

Package Maintainer: If you wish for this bug to remain open because you plan 
to fix it in a currently maintained version, simply change the 'version' to 
a later Mageia version.

Bug Reporter: Thank you for reporting this issue and we are sorry that we 
weren't able to fix it before Mageia 6's end of life. If you are able to 
reproduce it against a later version of Mageia, you are encouraged to click 
on "Version" and change it against that version of Mageia.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a more recent
Mageia release includes newer upstream software that fixes bugs or makes them
obsolete.

If you would like to help fixing bugs in the future, don't hesitate to join the
packager team via our mentoring program [1] or join the teams that fit you 
most [2].

Should be tested.  Myself have very little time.

Need some testing here.

Make bug link to Cauldron

Version: 6 => Cauldron
Target Milestone: --- => Mageia 8

Comment 10 Morgan Leijström 2020-08-16 22:40:14 CEST

Setting to QA team for testing of current state, preferrably on cauldron (if still valid there, probably it is on 7 too)

Comment 11 David Walser 2020-08-18 04:35:40 CEST

Ask on the qa-discuss and dev mailing lists for tests.  The qa-bugs list is for stable updates.

Comment 12 Thierry Vignaud 2020-08-19 18:31:33 CEST

I see "error: unable to find a GRUB drive for /dev/sda1. Check your device map." on line 78405
(which is fin as it's emty)
(BTW running the installer in English could help us, ie we wouldn't have to translate back from Swedish)

I see that grub.cfg contains:
search… --set=root c751a66f-8fba-40d7-bec5-61fb398f0871
which is UUID for /boot, which is normal as it search /boot in order to load kernel+initrd.
See:
* mount_part: device=nvme0n1p2 mntpoint=/boot isMounted= real_mntpoint= device_UUID=c751a66f-8fba-40d7-bec5-61fb398f0871

root UUID is c98904d8-fef5-4b66-9f4c-2ac0aba5248c (for which I see another search command from grub, which might be the issue)

Note for myself: I should log the output of pvs, vgs & lvs in report.bug


Could you redo such an install, copy your /mnt/root/drakx/report.bug on a USB key just prior to click "reboot" (or just run the "bug" command at this stage)
And then take a photo of the boot error message?

Comment 13 Thierry Vignaud 2020-08-19 18:38:53 CEST

@martin, I'm considering adding /lib/udev/rules.d/60-block.rules to DrakX

> @martin, I'm considering adding /lib/udev/rules.d/60-block.rules to DrakX

Revisit bug 20074#c65. I never found a way to fix the resulting race.

Comment 15 Martin Whitaker 2020-08-21 00:03:59 CEST

I tried to reproduce by following Morgan's steps (starting with the partition setup shown in his first installer log) but the system booted without error. I'm fairly certain this is the same as bug 22059 and hence fixed (even if in an ugly way). Also revisit 22059#c8 for discussion of why adding 60-block.rules is a bad idea.

Comment 16 Morgan Leijström 2020-08-21 00:13:52 CEST

Thank you for testing and other input :)

Closing as presumably fixed.

Will open fresh if i see similar again.
Will try to remember to run installer in english...

Thierry, thank you too.
- Will you remember to extend logging as you said ( pvs, vgs & lvs in report.bug) , or should we open an issue for that?

I already did it 2 days ago :-)
