[BUG] lvm2 pv + encryption = seg fault, core dumped #1847

@highvoltage this looks like https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=992164 as well ? |
|
I also have a more general question: is there currently any supported way to install a distro with LUKS + LVM with calamares? |
|
I am having the same issue trying with the Debian Live Installer. I tried with Manjaro and also has the bug. I cloned calamares main branch and still have this bug. Cannot create lvm + luks |
|
I am not sure if this is related to LUKs directly. I seem to also be affected by this if I try to setup LVM manually without LUKS |
It might be possible by setting up the partitions first, then just setting mount points; I'd have to try it in a VM. The Debian bug has a slightly more readable backtrace, but it's easy enough to trigger also in a debug-enabled build on a live system. |

Zero the tables, make a GPT table, start partitioning: The
Then carry on with LVM configuration: .. at this point I can get to manual partitioning, and configure up somethnig that kind of makes sense, but after that the installation fails anyway with being unable to create a partition on device |
|
Possibly related crash: On a new 8GB VirtualBox disk I tried manually partitioning with a new partition table, LUKS encrypted XFS On a different install I was able to do an "Erase disk" with XFS + LUKS with no crashing. Please let me know if you want me to create a new issue or not. |

Starting over: Make filesystems Start Calamares, note that the device is myvg, manual partition, edit the two partitions to give them a mountpoint. Do not check the format box; preserve the filesystem. Ignore the warning about the EFI partition -- because there's no EFI partition inside the PV, of course. Carry on with the installation .. oh, then it doesn't mount the parttiions, and proceeds to fill up @geckolinux the issue here is LVM, not LUKS -- please create a separate issue |
@adriaandegroot Is it not possible for them to still be linked? Say it is an issue with /dev/mapper devices and not really LVM directly. That would make it effect both LUKS and LVM separately but still be the same issue. |

Thanks for the reply @adriaandegroot . At any rate here's my separate bug report: |
Hi @volitank and @adriaandegroot, I can confirm that this happens without luks, just creating an lvm pv partition and then trying to create a volume group using it, relates in: (but I also understand that it could as well be linked because actually being a problem somewhere else as @volitank pointed out) @adriaandegroot when I installed Manjaro for the first time on a system about 2 months ago I worked around the installer issue by creating LVM stuff manually beforehand, similar to your description :-) The calamares version in use in my distro is 3.2.48-1 |

Hi @adriaandegroot,
...
I was trying to trick my installer again as I did some time ago once already, as pointed out earlier. I did it similar to what you tried here. I now ran in exact the same issue of not mounting partitions and then filling up the wrong volume. It's odd, since I managed to install that same OS some time ago already by tricking the installer somehow. I just can't recall what else I did to make it work. On thing that is missing in your description I think is that the EFI partition should be mounted into /boot/efi, at least I think this is what Manjaro Linux assumes. Not sure about other distros. But still with that addition it doesn't make a difference, the volumes are not mounted and the rsync fails because it fills up the wrong disk ;-) I will now try to mount the volumes manually before Calamares starts the rsync, let's see if that helps...., |
|
@JOJ0 Did you try and did it work? |
|
@hrvoj3e IIRC it did not work and I gave up on Calamares entirely. My solution then was using manjaro-architect, a higly configurable alternative installer. Try that, if the distro you want to install is Manjaro! It might cure your frustrations 😀 HTH |
|
Finally. It works.
The "fix" is to mount LVM volumes somewhere and I reported this in an existing issue |
