Arch to TrueNAS

[ParipeDeTriana]

I have a computer with several hard disks (one for the system with BTRFS and the data disks with ZFS) using Arch Linux. It is a powerful computer but since some time ago I only use it as a NAS, what would be the advantage of switching from Arch Linux to TrueNAS, could I keep the data stored on the data disks (ZFS)?

My condolences.

Well, at the cost of setting up TrueNAS, it's probably easier to maintain mid-to-long term.

could I keep the data stored on the data disks (ZFS)?

Yes, but permissions do not translate well between ZFS on Linux and ZFS on FreeBSD. You may have to redo them if you're using ACLs.

I have another question, what is the best (in terms of data transmission speed) way to connect TrueNAS on a PC to a MAC mini?

Also, you need to be aware that TrueNAS is an appliance. It is not possible to install arbitrary software other than what is supported. Quite a few people who switched over fell into the trap to believe they could also install their favorite tools/applications.

I am currently using a Mac mini as my everyday PC and the PC (running Arch Linux) only functions as a data server (as if it were a NAS). So I am interested in using an operating system (on the PC) that maximizes data transfer speed/reliability.

I applaud your bravery.

A rolling release Linux distro is a shaky host for ZFS storage. Especially important data.

The fact that on a live system you can have the ZFS modules (of an older version) loaded, meanwhile the ZFS utils (zfs-utils) gets updated to a newer version is disconcerting...

You're not wrong, but the breakage tends to be more annoying than dangerous. Stuff like a specific subcommand of zfs (I forget which) failing due to the kernel interface changing, without actually doing anything.

10+ GbE, though you may need an external NIC for the Mac, depending on the model...
