| blitz | Hey! Quick question: Is it possible to perserve certain partitions when using disko to deploy a system? I'd like to preserve the ESP and another recovery partition (can be identified by UUID for example) | 09:49:52 |
 lassulus | not easily, you would have to run just the formatScript and have enough space available, you can create some partitons with content = null; which would get ignored by disko, but the offsets for the partition you want to create need to be correct | 09:51:59 |
| blitz | mmh ok. maybe I'll write my own script that handles this for now, let's see :) | 09:53:17 |
| blitz | but thanks! | 09:53:23 |
| lassulus | that is probably easier for now | 09:53:41 |

 mou | Hi, disko community. I have a question. Couple years ago i installed nixos with disko integrated into installation. So disko was used to perform formatting of the disks. Since then configuration preserved in nixos configuration for this host. Overall config consist of nested elements: LUKS -> LVM -> Ext4 on partitions. Overtime i realized that 100Gb is too small for my nix-store volume. And planing to shrink home partition and LV and enlarge nix-store LV and corresponding partition.
But what i do not understand, what should i do with current disko cofiguration and how discrepancy of actual LV and Partition sizes with disko definition will affect NixOs boot process?
And what action should i take after making changes to LVM? | 16:32:09 |
 chaoflow | mou: I'd say the boot process does not care about the size of actual partitions, but rather about their existence and order. You could probably also use nixos-generate-config to get the filesSystems attribute set for configuration.nix - usually living in hardware-configuration.nix - and drop disko from the setup. | 16:50:54 |
| chaoflow | Note: with btrfs subvolumes or zfs datasets you wouldn't have the resizing problem, as those share the available space of one filesystem/partition while providing logical separation, e.g. for snapshots. In that case no LVM would be used but LUKS -> btrfs/zfs or using ZFS encryption, maybe not even LUKS - but I don't have experience with ZFS. | 16:53:16 |
| mou | Thank you for your answer. I thought about this trick as a precaution. fileSystems dictionary is much more undestandable and manageable when it comes to disaster recovery ))) | 16:54:01 |
 jappie | also, you can verify your config using nix repl, e.g. :bl nixosConfigurations.yourHost.config.environment.etc.fstab.source to check fstab (which uses some information from disko - mainly what to mount where) | 16:59:32 |
| mou | Thank you. This is invaluable. I actually always been interested how to check what disko configuration expands into. | 17:01:01 |
| jappie | there's also some systemd services that decrypt luks volumes I think, but I couldn't tell you which ones from the top of my head 😅 | 17:02:54 |
