I have submitted multiple bugs for ZoL, from prohibiting boot of zfs as root (for the sake of boot beeing faster (?) they are not doing zpool import -a(f) but r

    zfs has a feature where you can `cd` to hidden .zfs folder (you wont see it by `ls`, imagine it like /procfs but hidden) on root of zfs filesystem (if you have tank/whatever mounted to /whatever this would be /whatever/.zfs) with some interesting content: within .zfs/snapshot you will get a list of snapshots for that filesystem with materialized state (!!!) of fs when the snapshot was taken. Imagine (instead of rollback the snapshot), just copying the original file(s) from there, with content from the time when snapshot was created. This is imho, the killer feature of zfs, maybe matching only by VMS or DragonflyBSD hammer filesystems. They were/are both better at it (`undo`!) but zfs comes closely. And it is broken for months now.

      I haven't noticed that issue on Proxmox (been using zfs with it for approx. 6 months). Currently on zfs 0.8.4 (and I've done that previously). Are you using a distro supplied zfs (potentially old) or rolling something more bleeding edge?
      • stiray 6y ago
        Just for any case, I would really love to solve this, I accept the fact that it is connected with upgrading the modules but this just is no reason for breaking backward compatibility. root> zpool --version zfs-0.8.4-1 zfs-kmod-0.8.4-1 root> ll /.zfs/snapshot total 0 drwxrwxrwx 2 root root 2 jun 15 08:48 ./ drwxrwxrwx 1 root root 0 jun 10 07:53 ../ root> cat /etc/yum.repos.d/zfs.repo [zfs] name=ZFS on Linux for Fedora $releasever baseurl=http://download.zfsonlinux.org/fedora/$releasever http://download.zfsonlinux.org/fedora/$releasever /$basearch/ enabled=1 metadata_expire=7d gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-zfsonlinux [zfs-source] name=ZFS on Linux for Fedora $releasever - Source baseurl=http://download.zfsonlinux.org/fedora/$releasever/SRPMS/ http://download.zfsonlinux.org/fedora/$releasever/SRPMS/ enabled=0 gpgcheck=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-zfsonlinux But nevermind, this is something that was working since zfs as root was brought into FreeBSD (and we are talking about FreeBSD not ZoL), never had issues about it.

      > And it is broken for months now. This guy speaks without knowing. I just tried going in my .zfs/snapshot on my CentOS 7 system running kernel 3.10 and ZoL 0.8.3 and it's working. I can list snapshots and cat file off a snapshot.

        After 10+ years of using zfs, I just "might" know something... ;) While your 1 year old versions of ZoL just "might" not prove anything.
        • znpy 6y ago
          if you had actually been using it during the last 1.5/2 years you would know it work. otherwise you're just talking about stuff (zfs on gnu/linux) you know little about. if you use zfs on freebsd then good for you, but that doesn't mean you can spread disinformation about zfs-on-linux. btw: freebsd dropped its own implementation of zfs and is rebasing onto zfs-on-linux (from 2018: https://lists.freebsd.org/pipermail/freebsd-fs/2018-December/027085.html https://lists.freebsd.org/pipermail/freebsd-fs/2018-December...). that's how good zfs-on-linux is.
          • stiray 6y ago
            Just update your outdated ZoL to latest version. Than we can talk. And you might just agree.
            • laumars 6y ago
              I run ZFS on both Linux and FreeBSD. On Linux I compile from the latest releases. I’ve honestly not noticed any issues either. Are you absolutely sure this isn’t something you’ve misconfigured yourself? For what it’s worth, I do prefer FreeBSD over Linux but not not for any reasons relating to ZFS.

      $ cat /saspool/debian/master-buster/.zfs/snapshot/ci/etc/issue Debian GNU/Linux 10 \n \l ZFS 0.8.4 on Linux 5.4.43 — just as a data point in case you're trying to track this down. Both built from source, no distro patches. (Yes my "tank" is named "pool"; /saspool/debian/master-buster is a template for my containers, "ci" is one of the containers.)

      Works for me on Debian Unstable... sudo zpool --version zfs-0.8.4-1 zfs-kmod-0.8.4-1 uname -a Linux xxx 5.6.0-2-amd64 #1 SMP Debian 5.6.14-1 (2020-05-23) x86_64 GNU/Linux

  > they are not doing zpool import -a(f) That's an initramfs bug; the initramfs scripts are not actually supplied by the ZoL project. You should file a bug report against your distro's initramfs package.
  • trasz 6y ago
    That's part of the problem. From the user point of view it doesn't matter if the bug is due to initramfs, or the kernel, or ZoL, or whatever else. What matters is it doesn't work. With FreeBSD development model it's easier to get it to work, since it doesn't need to go through so many separate groups of people.
  • stiray 6y ago
    I am on fedora with added zol repository and fedora 30 doesn't supply any zfs modules or initramfs scripts. I had to do my scripts to verify that the modules are included and don't break my boot process. And it worked like a charm... for a while.
    • eqvinox 6y ago
      So... the bug is in your own scripts? I'm now thoroughly confused what your complaint is :)
• tomxor 6y ago
  > .zfs/snapshot still doesnt work I've been using this as a server backup solution for over a year, I assure you zol snapshots work, including access via the .zfs directory.
• michaelmrose 6y ago
  The actual problem you are having is that there isn't a setup option on virtually any distro that will set this up for you but you are clearly setup incorrectly. I was using Funtoo with a zfs root for years until the machines CPU died. The process of booting up looked like hit power button wait for desktop to show up. The "basic mistakes they are doing" are completely a function of your distro not having a way to easily set this up and you not knowing how to use it correctly. As far as I know the only distro that supports zfs on root via its installer is at https://project-trident.org/ https://project-trident.org/ You might try it in a virtual machine.
  • JdeBP 6y ago
    Ironically, Project Trident was the desktop part of TrueOS Desktop, which in turn used to be PC-BSD, a derivative of FreeBSD.
• paulmd 6y ago
  I have ZFS images that I can't send from my freebsd server to my 16.04 server with the ZoL repo enabled. Given that it's my personal data I can't really submit until I narrow down to a minimal reproducing case, but yeah, there are bugs.
• crazy_hombre 6y ago
  Stop spreading FUD. ".zfs/snapshot" has been working on Linux for years now. I don't know when you last used ZFS on Linux, but just because you haven't used ZoL for a while doesn't mean that the developers stopeed working on it. Also, me and hundreds of other people have been booting off of ZFS on Linux for years. Your issue is most likely in your distro's initramfs setup or you must have botched the initramfs config yourself. If you're just used to FreeBSD, just stick to commenting about FreeBSD without maligning other operating systems.
  • trasz 6y ago
    Again, if it doesn't work, then it doesn't work; to users it doesn't matter _why_ - whether it's a problem with ZoL code itself, or with distro-provided initramfs. It's the end result that counts.
    • crazy_hombre 6y ago
      Well if it's working for everyone but a select few, then I'd argue the problem is with those select few and not the product.
