Well, on this system, I've done this a few times without any problems. Just add some space with lvextend, resize file system and done. It doesn't seem to be working today tho. Yesterday either.

Well crap. I checked once ages ago to see if I could do anything with LVM and the commands did list things. I guess LVM works on those but I can't recall what I was booting. Given it was a while ago, likely systemrescue thingy. That doesn't use Gentoo anymore so not sure on if that would work or not. I may have a old copy around here somewhere. Could put it on that Ventoy thingy. See if that works. I was hoping to avoid that. :/ I thought maybe I was missing something or something changed that I couldn't find, yet. Thanks for the help. We tried. Dale :-) :-) P. S. I have some 500GB drives in a box somewhere. Could move the OS over to that and have even more room. I could do like I did on my new rig, make everything big enough that I'd need to worry about the rig blowing smoke before running out of room. ROFL
