| xored | can anyone help me out? this is driving me crazy, i'm building the same config (asides for disk names) on a VM for testing and on a server for deployment, the server is failing as it apparently cant find /dev/mapper/crypted1 which is my first luks partition, I run this on the VM and it doesn't fail at all, what could be happening here? | 01:28:56 |
| xored | this is the last from the logs https://pastebin.com/vif4ag09 | 01:30:40 |
| xored | apprently it was some stale zfs stuff on the disks or something, i did a provider install of another distro and apparently that wiped the data or did something that disko didnt by default so when i started nixos-anywhere after that install it worked | 02:08:39 |
| xored | i saw disko tries to wipefs and dd some initial blocks but i still ended up in some corrupted state it looks like | 02:09:53 |

 @brian:bmcgee.ie | I'm experimenting with a new setup, using vmVariantWithDisko to test things out. I've defined a few btrfs subvolumes, one of them being /home. It seems that the user creation script is running before the subvolumes are being mounted, which means my user has no home for example.
Is there something I'm missing / misconfigured?
| 17:07:21 |
| @brian:bmcgee.ie | I'm seeing nixos systemd[1]: home.mount: Directory /home to mount over is not empty, mounting anyway | 17:12:39 |
| @brian:bmcgee.ie | Trying out some suggestions from here https://github.com/nix-community/disko/issues/192 | 17:49:44 |
|  phaer changed their display name from phaer (8650 at 38c3) to phaer. | 19:23:46 |

| Mic92 | Also would go for the neededForBoot | 21:48:19 |
| Mic92 | Afaik we are doing zpool destroy, but if that doesn't not help, blkdiscard /dev/nvmen0p1 might | 21:50:05 |

| @brian:bmcgee.ie | neededForBoot doesn't seem to help. Been reading through https://github.com/NixOS/nixpkgs/issues/6481 as well. | 16:51:55 |
| @brian:bmcgee.ie | Mic92: I adjusted by btrfs volume definitions to more closely match what Lily Foster had, mainly just adding a root mountpoint of /vol/root and removing mountpoint definitions in my subvolumes since their paths matched anyway.
Now neededForBoot seems to have the desired effect and /home is being mounted before the user activation script is trying to do anything.

| @brian:bmcgee.ie | yeah, so I missed the eval warnings. Turns out it just wasn't mounting things which is why it appeared to 'work'. Back to the drawing board. | 14:00:50 |
