Also please note, as far as I understand, that even if you use only one size drives (to get the most out oof the space) UnRAid ZFS doesn't support running all drivers in one big ZFS pool so to say. You still need to have i non ZFS pool driver in your "array". Now you can have this drive formatted as ZFS and you can have a parity drive with it but it sure looks like you cant go with just a ZFS raidz pool. As far as I understand the "array" in the case of UnRaid is a name for a sort of wrapper that start end stops services , disk shares and application alike. If you run with just a raidz pool the Unraid "array" wont start , you can of course start your zfs pool and your applications manually but it sure looks like UnRaid is not built for that scenario.

Wow, that successfully resolved the issue! Performing a stop of the "array", then an export of my three pools and restarting the "array" again. Everything is back to normal now. I appreciate your speedy assistance very much!

Hi, since I am new to Unraid I jumped straight into running ZFS that I setup ona late rc build and now 6.12 So I have set up a small zpool with 4 drivers as well as a standalone zfs drive for "disk1" and a single cache drive, created shares and exported with SMB, and I also installed docker and it all worked. But today something odd happened and now in the web GUI on the "Main" page all my ZFS disks show as "Unmountable: Unsupported or no file system" and it wants me to format all the drivers. However, all the zfs pool are infact online and I can access all the data, I can stopp and start the "array" and it goes back to this state. I can scrub the pools and it also fine, and yes, there is no problems accesing to docker contains or the SMB shares.

Any ideals on how to resync it so to say ?
