 BeatLink | Am i on the right path? | 12:57:15 |
 Mic92 | BeatLink: disko will only format the disks that you have configured. However I would use not generic names such as nvme0 but instead longer ids that contain the nvme serial numbers. Because nvmes might be not stable and change after reboot: lsblk --output NAME,ID-LINK,FSTYPE,SIZE,MOUNTPOINT | 19:51:17 |
| Mic92 | Just include your main drive for nixos-anywhere in your nixos configuration. and for your data partition use the disko cli | 19:52:12 |
| BeatLink | thanks | 19:52:42 |
| BeatLink | I wanted to also use disko to handle mounting the drive in the installed system | 19:52:55 |
| Mic92 | You will need to add a fileSystems entry in your nixos configuration for your data drive. | 19:53:01 |
| BeatLink | right | 19:53:07 |
| BeatLink | I've already went ahead and coded in my script to comment out the data drive during installation and uncomment it once the installation is complete | 19:53:34 |
| Mic92 | I guess that also works. | 19:53:48 |
| BeatLink | yeah, that way its disko all the way down | 19:54:08 |
| BeatLink | a bit risky tho, since if the script fails to comment the line, there goes my cat pictures lol | 19:54:23 |
| BeatLink | i have an off site backup setup tho so im not tooo worried | 19:54:41 |
| Mic92 | Still time consuming | 19:54:52 |
| BeatLink | yep | 19:54:58 |
| BeatLink | it would be great if disko took an argument with a list of which devices to ignore | 19:55:27 |
| BeatLink | like --ignore-device=/dev/sda | 19:55:39 |
| BeatLink | and that could be repeated numerous times | 19:55:49 |

| SkamDart | Running this https://gist.github.com/SkamDart/30af3d3e4d93ee2dbd732ff3645bb29e config and getting the following error
/nix/store/32ycfg2axcjxdii9irj0fddbcb2xlr9z-disko-format-mount/bin/disko-format-mount: line 6
3: mkfs.fat32: command not found
nothing came up in my nix-locate search and mkfs.fat32 isn't provided by dosfstools or e2fsprogs.
does it make more sense to write a custom _create attribute that calls out to mkfs.fat -F 32 or am I missing the obvious way to do this?

 netpleb | in my disks.nix I have a btrfs setup like the example https://github.com/nix-community/disko/blob/master/example/luks-btrfs-subvolumes.nix but only recently noticed when trying to nixos-rebuild switch that I get this error:
Dec 11 15:26:26 aleph0 systemd[1]: Activating swap /.swapvol/swapfile...
Dec 11 15:26:26 aleph0 kernel: BTRFS warning (device dm-2): swapfile must not be copy-on-write
Dec 11 15:26:26 aleph0 swapon[367622]: swapon: /.swapvol/swapfile: swapon failed: Invalid argument
Dec 11 15:26:26 aleph0 systemd[1]: \x2eswapvol-swapfile.swap: Swap process exited, code=exited, status=255/EXCEPTION
Dec 11 15:26:26 aleph0 systemd[1]: \x2eswapvol-swapfile.swap: Failed with result 'exit-code'.
Does disko need to set some mount option differently for the swap subvolume?

| netpleb | I found the issue. At the bottom of this answer it says: "Swap file can't be located on a btrfs raid of any sort." | 00:04:11 |
| netpleb | * I found the issue. At the bottom of this answer it says: "Swap file can't be located on a btrfs raid of any sort." But alas I recently transitioned mine to a raid setup. Will now move swap over to a non-raid partition and hopefully it will solve the issue. | 00:04:55 |
 magic_rb | Friendly recommendation, don't use swap files | 01:47:09 |
| netpleb | swap files specifically? or swap in general? I do not know enough about either really to have an opinion. | 04:07:06 |
| BeatLink | Swap on CoW filesystems like BTRFS and ZFS is a bad idea | 04:07:47 |
| BeatLink | swap is a write heavy requirement and CoW amplifies writes | 04:08:03 |
| BeatLink | it will thrash your storage devices, especially if its SSDs | 04:08:13 |
| BeatLink | if you must use swap, create a dedicated partition for it | 04:08:39 |
