With LVM, I usually either move data to a larger drive or just add a additional drive. I think I shrunk once, I think. Still, one always wants to have options. One thing about LVM, I already know how to use it. I've got notes on how to do things and it has worked. With ZFS I'd have to learn it all over again plus it could confuse me with my using LVM on my main rig. In a way, if I build a Raspberry NAS, I'd like to have Linux and LVM on the thing. At least then I have experience moving data and such. Right now, I don't even have the basics of ZFS or BSD. I'm not saying TrueNAS is bad or anything, just that I don't really care for the learning curve. Then the confusion part on top of that. I've read there are distros built for Raspberry thingys. I'd be shocked if it isn't doable. I'd be shocked if someone hasn't already done it even. Time will tell I guess. Dale :-) :-)
