I still have some things under /mnt too. After a big change a few years ago, and a couple with me building the new rig, I did move some stuff to places where it is more logical. Given the amount of video data here, I now organize even my pv's by the type of data. Most is encrypted but some is still plain file systems. I want to buy enough hard drives that even one of my data file system's is encrypted. I didn't encrypt it in the beginning and now it would take about 3 spare 16TB or 18TB drives hard drives just to reorganize. Create encrypted file system, move files over and then have the old drives as spares. I have not found a way to encrypt in place without data loss. Sometimes old ways of doing things comes back to make problems. Usually, when I build a new rig, I fix that as I add to fstab. Sometimes tho, those old ways are hard to shake. >> I didn't put anything OS related on LVM this time.

Very funny Scotty... now > beam down my pants! I still remember my first build and that little 30GB hard drive that was for everything, OS and data. Eventually, I added a separate drive for /home. Back then, 30GBs was a LOT of room. That was about the biggest drive they made back then, that was affordable anyway. This takes me back to around 2003 or so. Computers have come a long ways since then. Hard drives have certainly grown. Heck, they closer to 30TBs than they are to 30GBs. Have to watch my T's and G's there. o_O Dale :-) :-)
