I learned my lesson on SMR a while back. I googled and made sure it was a CMR drive before I ordered it. I had to pass by some SMRs to find a good deal that was CMR tho. I don't plan to move data just add the drive as extra space. Adding it to LVM should be easy enough. Sort of thought about switching to BTFRS (sp?) but just not sure. LVM is working well for me at the moment.
You know I push the raid wiki :-) Even if you're not into raid there's some good stuff there. I'm very ambivalent on btrfs. It has a lot of good features, but it's a trade-off. Do you want a jack-of-all-trades filesystem, or do you want separate layers doing separate things. My feeling is separate layers.
I've got my hard drives, then dm-integrity (so corruption triggers a read-failure), then mirror-raid, then lvm, and finally ext4.
I'm trying to get snapshotting to fire automatically on boot once a week, so when I emerge, I can always roll back easily :-) I'm not sure whether systemd will do it, but if I have a once-a-week timer which activates a fire-once-on-boot service, then that'll be perfect. The timer fires on Friday, the snapshot fires when I reboot Saturday morning ... and then I try not to break my system with a messed-up emerge :-)
Cheers, Wol
