I moved the opposite direction (btrfs->zfs) because I had issues with my main btrfs rootfs constantly degrading to read-only mode, causing my system to crash and require rebooting.
With ZFS I’ve had no such issues. ZFS uses noticeably much more RAM though.
- noodlesUK 8y agoYeah, I was on Gentoo at the time, which didn’t make it particularly difficult (when everything is source code it doesn’t really matter), but I’m on Fedora now, where the story is a bit different. Ubuntu shipping the binary modules is good. Do they support booting from ZFS simply (that is, are the kernel modules in the initramfs)?
- josteink 8y agoYeah. All my systems are pure ZFS systems. The initial install is a bit involved (live-cd, manual partitioning + debootstrap) but everything just works (tm) after that, including booting into specific snapshots from grub. There’s a good guide on github: https://github.com/zfsonlinux/zfs/wiki/Ubuntu-18.04-Root-on-ZFS https://github.com/zfsonlinux/zfs/wiki/Ubuntu-18.04-Root-on-...
