[SOLVED] zpool log and cache device

[isi]

I have installed PBS Server for testing.
I have 2 spare nvme Devices. Is it ok, to add the nvmes as a log and a cache device to the pool ?

Looks like its ok, to do. It just isn't in the GUI.

With the data on rotating rust?

I would highly recommend to not do that. You won't get the result you are expecting; both SLOG and Cache work differently than most (new) users tend to believe.

Instead of this add both NVMe as a single mirrored "Special Device". Search for it, it has been discussed several times.

Thanks for giving a heads up. I'll check this.
