I am in the process of making a DIY NAS box and I am debating between mdadm + BTRFS and ZFS. What are your experiences with using ZFS on Arch? Have you run into any major issues? Does ZFS being an external kernel module cause any annoyances with the frequent Arch kernel updates?

Give me the dirty details! Any recommendations or pitfalls I should avoid?

Thanks!

    It has been years since I last used zfs. Here’s what happened to me. I had a zpool nearly full. It died of 0 B/s read/write. Previously I had to recreate a zpool because a metadata error happened from loose connection. I forgot to export before unplug several times and processes accessing it went into D state, requiring a reboot to cleanup.
