The way I usually do a new drive, I partition the drive and name the partition. That way I know something is on it. The name usually, almost always, tells what VG it belongs too. One reason I do that is in case I'm replacing a drive with a new drive and I'm running cgdisk, I can be reasonably certain I'm working on the correct drive. If something shows up with a label of a VG, it's not new and empty. I tend to run smartctl -i to, just to be sure. Some don't partition but it's sometimes hard to tell there is data on it. Keep in mind, I have about a dozen drives in use here. It's a lot to keep up with. Also, when I buy a drive, I put the brand, size and last 4 or 5 digits of serial number on a piece of paper tape. I then stick that on the end of the drive where the connectors are. That way I can see exactly which is which when I am unhooking one. Imagine unplugging a drive thinking it has been taken off one VG but is on another VG and the wrong one. No telling what kind of a hornets nest that would upset. As a general rule, OS drive excluded, I always add a whole partitioned drive to either a volume group on LVM or a pool thingy on TrueNAS. My OS is divided but that is the only drive that isn't all one partition and all on one VG. There's a method to my madness sometimes. My biggest problem, I need to buy about two dozen 16 or 18TB drives and have a server type thing to put them in. Then redo everything from scratch. Dang that won't be cheap. o_O I'm updating the backups now. It's been a couple weeks. Gonna be a while. May take overnight. Just for fun.

I then have the TrueNAS system that backs up other data which now has three drives. This sounds massive don't it? ROFLMBO Anyway, I got it running again. It'll last until I can get larger drives. That 6TB on datavg and 8TB on crypt will likely be the next ones I replace with larger drives. Likely 14, 16 or 18TB depending on deal I can find. Thanks. Dale :-) :-)
