As seen on picture: during boot it manages to open encrypted LVM, mount contents, then complain.

As an effect (of dracut not working?) this machine now since updates also have compatibility problem with kernel versus graphics driver and virtualbox module versions. :(

I've not much experience with crypted partitions.

could be b/c they're several soft links to the same devices and the one in /etc/cryptab differs from the one used after ("mapper/foobar" vs "foobar").

I would guess it is not named /dev/mapper/crypt_sda5
IIRC it should be a symlink to /dev/dm<something>

Can you also add the content of /etc/mdadm.conf?

I have no idea how things are done nowadays, I have never touched dracut or systemd :(

So dracut should copy/use the /etc/crypttab and thus bring it up as /dev/mapper/crypt_sda5. If it doesn't it would bring it up as /dev/mapper/luks-$UUID

I've got a similar-ish VM somewhere I'll update it and see if I can reproduce.

thanks guys for looking into this

/etc/mdadm.conf does not exist

While you have loaded this landscape in your brain, i suggest a couple more exercises ;)


Bug 12033 : make an encrypted logical volume inside a LVM, and later try to remove it.


Also check it can create and remove a encrypted regular physical partition.


Also a question, can it resize an encrypted logical volyme correctly nowadays?  I remember it had some problem when i tried a couple years ago.



  I would be very grateful if the issues can be solved :)

I also now and then get the KDE systray informational popup saying:

Closing then

@TV did you mean to close this one?

Yes. Isn't it fixed?
If not, sorry

(In reply to Thierry Vignaud from comment #15)
> Yes. Isn't it fixed?

I don't see any comments relating to it being fixed but perhaps I missed something?

Maybe my comment 12 was misunderstood.
I meant to report a side effect (or possible another bug).

Except for diskdrake and related tools like dracut the system is working and runs on /, swap, /home logical LVM partitions inside the encrypted partition.

Still not working after todays updates.

log of update where it think it need password

Another effect of the same problem: update triggered a bunch of:
"

Please enter password with the systemd-tty-ask-password-agent tool!

Webmin see it, and use the form

I just setup a test VM installing with the same layout from the final x86_64 iso.

Installed same disk layout + GNOME.
After first boot, I installed updates, including new kernel.

All went smoothly and reboot also worked fine.

Can I ask if in your testing you've done a fresh install or if this is continually being upgraded?

I suspect the problem stems from an invalid dracut initrd fixed some time ago. It wouldn't use the crypttab properly and would ultimately startup the luks under a different name. THe system could then misbehave.

This is now resolved (I fixed it just before this bug was posted, but it may have taken a while to get into the ISO etc. and thus the fix wouldn't come in until later), as a result, you may have a /dev/mapper/luks-* device instead and can't really escape from using it, even if your cryptab refers to a different device.

I suspect a fresh install from latest ISO would be fine and not encounter this problem.

Thank you Colin

final iso available already?

Ah, nice, I take your word that fresh installs should work now.


The system where i initially encountered the bug was a mga2 system x86_64, upgraded using mga4-beta2 DVD.

Then i tried a fresh install in a virtualbox VM, (see bug description) but had time to post this bug only a few days after.
- so probably just before your fix.



What about upgrading asystem (mga2 or 3) which have this layout (encrypted LVM containing /home and more)
I guess they are locked into this bug, or is there a workaround?
Should there be a notice in the errata maybe?

In reply to my comment 21:

I made a sucessfull reinstall on a system that had /, /home, swap on LVM on a luks partition, separate /boot.

(mga4 installer unlocked the encrypted partiton with the key i gave, and the LVM  tab then appeared)

I reformatted all but /home

Full OK.  Closing fixed.
