    nvme on linux

    I'm thinking of building a new home "server" and to maximise the amount of storage space I can get I thought I would try and get a board with an m.2 SSD. My distro of choice is generally debian because well, i know how it works, but that does tend to mean im a bit behind the times as far as hardware support goes.. How good is the nvme support on linux these days? Am I going to have to role my own kernal or is it something I needn't worry about?

    Side note, this will be the first full rebuild this system will have had in about 20 years.. Up till now its been progressively replacing parts and expanding the raid (its gone from 4 ide drives, to 8 ide drives, to 3 sata drives and now sits at 5 much larger sata drives).

    I'm guessing ext4 isnt the hot new thing anymore.. Whats a good disk setup that will let me use the excessive amount of ram the system is going to have, and the rest of the nvme disk as cache.. zfs still a thing?

    Been built in since kernel 3.3. Xfs or ext4 are both fine. I'd only change away from those if you know you need a feature offered by an alternative

    While this box holds all my storage, it also does a bunch of other stuff.. I would generally prefer to stick with a distro I know so I can get it all setup and working again..

    You should use a file system made by a murderer.

    I don't think you will be behind on the hardware support in debian. the kernels are mostly recent, and late into the release cycle you can usually switch to testing without any problems. I run my work computer on debian testing all the time, and just try not to update for a month when a release happens.

    Besides, debian stretch was just released, some months ago, and if you manage to become friends with the devil i.e. systemd, its fine.

    Pretty sure future maintenance is also a requirement.

    I installed Xubuntu 16.04 on an NVME based laptop last week, worked fine. Crazy fast.

    Got my trusty Intel i3 v6 in a delightful Fractal Node 304 with four WD 3TB disks (I had a price goal) and a Samsung 960 pro NVME 256GB boot and system disk. It runs on Ubuntu (because well, it's the easiest) and uses ZFS-on-LInux for the RAID. ZFS is the real fucking do. Robust as hell and very, very configurable with snapshots, scrubbing etc and works fine with Samba. My next project is to do a Samba 4 AD implementation so I can replace our NASes at work next year.
