ZFS On Unraid? Herer's How (Bonus Shadowcopy Setup Guide) Wikis & How-to Guides

[15712027333732386322906213952373] ZFS on Unraid You are in for an adventure let me tell you. ZFS on Linux is great, and finally mostly mature. It has great performance – very nearly at parity with FreeBSD (and therefor FreeNAS ) in most scenarios – and it’s the one true filesystem. Look, I like BTRFS too. And I did a lot of failure mode testing to go with these videos, but it held up surprisngly well so maybe those videos aren’t super interesting. But ZFS? ZFS is the FS. Unraid is not built to support ZFS. The last few weeks have been the first time I’ve used Unraid in some time and it has matured well. It seems to have a diverse and talented user base and the user base is adding a lot of features and flexibility to the system. Getting Started First: Backup your data. Things can go wrong and your data can get trashed. ZFS support on Unraid is not supported by Lime Tech or, well, anyone. It’s a life-in-your-own-hands scenario using the system off-script like this. I didn’t see a clean way to use only a ZFS pool either. You’ll need at least 1 or 2 other storage devices to create an “Unraid Array” so that the Plugins/Docker/VMs tab will work in Unraid (bummer). Here is the info for the ZFS on unraid plugin: Here is the github link: Plugins on unraid involve pasting links into unraid, so that’s neat. The plugin documentation has a handy hint about limiting the arc cache size which is great for mixed-use boxes. Otherwise the arc filesystem cache will happily use all your ram. Whether or not this is a bad thing is probably on the side of not really a bad thing if it uses all your ram as it will give up ram if the ram becomes short. There have been cases in the past where that mechanism was not good at sharing memory with other processes, but by and large you may not need that. Experiment, though, and report your results here for the benefit of everyone? Creating your zpool lsblk This will help you identify block devices on your system. I had sd[b-e] av…
