When the OpenZFS on OS X development began just over a year ago, I ran the test builds that where made available, though these supported new features through feature flags it was very early days, attempting to scrub a zpool on a i7 MacBook Air with a USB 3 disk would spike the CPU for the duration and again the integration was still missing, you manually had to import & export pools. Zevo had much better integration with OS X e.g disk would be automatically mounted when connected to system just like any other disk with a supported file system and it supported a v28 of the filesystem whereas MacZFS supported a much older version. Prior to the development of OpenZFS on OS X, the two choices for using ZFS on OS X where Zevo or MacZFS, Zevo originally started out as a commercial product but switched to a freebie after Greenbytes picked it up.
#Openzfs sharenfs mac
Unfortunately having an unlock key file stored in an encrypted zfs dataset cannot be used directly, so the pool must use keyformat=passphrase and keylocation=prompt.I recently moved my last Mac from Greenbytes Zevo to OpenZFS on OS X, the reason for both sticking with Zevo & switching to OpenZFS were one and the same, CPU usage. If you have not only one encrypted pool/dataset but multiple ones and you want to import and unlock them at boot, so that they can be automounted using the hardware-configuration.nix, you could just amend the option. Import and unlock multiple encrypted pools/dataset at boot If your network card isn't started, you'll need to add the according kernel module to the initrd as well, e.g.In order to use DHCP in the initrd, network manager must not be enabled and networking.# In /etc/nixos/hardware-configuration.nix: # Create new root datasets # zfs create -o canmount=noauto -o mountpoint=/ rpool/nixos/empty # zfs snapshot # Replace existing entry for / (root) withįileSystems. If you create a zpool, it will not be imported on the next boot unless you either add the zpool name to boot. Visit there for details and if an issue arises, submit an issue or pull request. devNodes = "/dev/disk/by-path" to your configuration.nix file.Ĭommon ZFS installation guides are now maintained at OpenZFS Documentation website. If you are running within a VM and NixOS fails to import the zpool on reboot, you may need to add boot.This behaviour can be disabled by setting boot. By default, all ZFS pools available to the system will be forcibly imported during boot.
Hibernation must be either disabled with boot.kernelParams =, or enabled with a separate, non-ZFS swap partition. Use boot.kernelPackages = .latestCompatibleLinuxPackages If you are running an newer kernel which is not yet officially supported by zfs, the zfs module will refuse to evaluate and show up as broken. Newest kernels might not be supported by ZFS yet.15.2 Alternative 2: Rebuild ZFS with Mail Support.15.1 Alternative 1: Enable Mail Notification without Re-compliation.15 Mail notification for ZFS Event Daemon.13.2 Import and unlock multiple encrypted pools/dataset at boot.13.1 Unlock encrypted zfs via ssh on boot.7 Changing the Adaptive Replacement Cache size.
