modules/nixos: add disko-zfs-swap #1252
Conversation
|
Should I test installing this on build01? |
No, I'll do it myself. I would appreciate a response to #1207 (comment). |
Without trying it myself, I can't tell. |

@Mic92 I tried this on build01. Installed, booted, another zfs import error. Is there some sort of weird systemd-boot / zfs problem? |
No. I use systemd-boot in many places. Only thing I can think of is that the pool is not exported correctly. In nixos-anywhere we do this: https://github.com/nix-community/nixos-anywhere/blob/f99d120b3788a286989db4e592a698f5d310d2f6/src/nixos-anywhere.sh#L516 |

I disabled uefi on build03 so now it is the same as 01 and 02. |

For a new installation or incremental one?

Seems to be a problem with the size of the disk, test works if it is 1G or created as a sparse disk. I've seen some comments that sparse can't be problematic so not going to use it.

Doesn't this suffer from the same issue that we also have with swap files on zfs filesystems? Also now that zfs has proper direct I/O maybe this is not an issue? https://github.com/openzfs/zfs/releases/tag/zfs-2.3.0-rc1

zvol is used as an example in the zram-generator docs so I'm assuming that it works.

Going to test this on build01, created the volume manually and added the writeback device in #1689. |
