    Problems with ZFS are scary as hell since the ZFS module can be the single point of failure for not only all local pools, but also all remote backups where that backup is populated with 'zfs send' (e.g. the hole birth bug and the large block size bug). This is why I ensure I have one backup tier populated by independent, dumb as fuck, and therefore dependable, rsync.

    You do not need to compile zfs, that just makes updating harder. Use OpenZFS 2.0.1 from here https://github.com/openzfs/zfs/releases and they support installation from within the OS' package manager for multiple distributions: https://openzfs.github.io/openzfs-docs/Getting%20Started/index.html
  • Changing pool ashift value?
    reddit.com/r/zfs | 2021-01-11
    Currently that's a limitation of OpenZFS, at least until this issue is closed: https://github.com/openzfs/zfs/issues/9013. Also documented in the man page here: https://openzfs.github.io/openzfs-docs/man/8/zpool-remove.8.html (When the primary pool storage includes a top-level raidz vdev only hot spare, cache, and log devices can be removed). Unfortunately it is quite hard to implement top level raidz removal until raidz expansion is implemented first (https://github.com/openzfs/zfs/pull/8853). Even with single disk support, top level device removal is very useful to correct mistakes (say you wanted to add a log device to a large pool, but forgot the log keyword when adding a small flash disk). So no, this won't work with current OpenZFS. Your only option to expand a raidz vdev would be to replace all disks in the vdev with larger models and wait for for resilvering to complete after each replacement.

  • OpenZFS 2.x on Debian : Your experiences?
    reddit.com/r/debian | 2021-01-08
    0.8 has been great - there are/have been some issues that can bite you when adding and removing vdevs in certain configurations, though. For example this (prevents you from running trim if you removed a vdev from the pool) is still in the latest debian package: https://github.com/openzfs/zfs/pull/10227
  • I have eight fresh disks in my proxmox server, how to ZFS them wisely...?
    reddit.com/r/zfs | 2021-01-08
    They won't. You should make absolutely sure you start out with the latest OpenZFS (2.0.1 at this time) https://github.com/openzfs/zfs/releases It contains sequential resilver (rebuilding is called resilvering for zfs). The resilver time will be limited by how fast the drive can be written to that is being integrated into the vdev.
