I will if I can, as it stands I have four 8TB seagate drives, enough for my actual storage need, but I want to have two parity drives for extra protection.
I am planning on running ZFS with Zraid2, the drives are the final piece of the puzzle to at least get it working.
When I planned the build, I planned to get another controller card and run two SSDs as well, one for cache (I can add that later), and one for VM/App storage, I also planned on getting an Intel GPU for transcoding video, and a 10Gig NIC, mainly just to say I have it, as my network isn't more than normal gigabit.
It is getting more important to complete the build as I need to move my media from single, non raided hard drives in my computer to a well raided server that I can configure for bitrot protection.
That's a much more sophisticated setup than mine! It may even be overkill (depending on what it is you want to host, and to how many).
I've been running two enterprise-grade Toshiba 16TB drives in a btrfs RAID1 since last summer. No SSD for caching (though the OS and my Docker containers run on one, with regular syncs to the slower spinning drives). No complaints so far.
I know it is a bit complex, but after seeing the shenanigans Synology tried to play and reading review about Ugreen NAS units and how they seem to connect to external servers often, I just decided to roll my own TrueNAS build.
I am using an AMD Ryzen 4600G, 32GB of RAM, a 500GB boot SSD, the only mATX board I could find with six SATA ports, the Asus B550m Pro4 and a Corsair SF750 750W PSU to power it all.
Props for the powerful DIY! You're right about the pre-built models. I'm coming from a QNAP one, and while they're good for learning the ropes, they'll become pretty limited after a while. That, and the shit they're trying to pull with proprietary HDDs.
A self-made rig gives you a lot more flexibility, although it requires you to learn a bit more. But seeing that you're already getting comfortable with GFS, I guess you'll manage just fine!
To be perfectly honest, I don't know what GFS is, I have been a Linux sysadmin for a few years, but never came across that.
We used LVM and ext4 for the storage in those VMs
If you've got that experience under your belt, you'll be just fine. I haven't tackled zfs myself yet (I'm lacking the RAM, plus I was put off by the ECC RAM recommendation). But I know it unifies a lot of the things you're already familiar with under one roof (volume management and journaling) and adds more cool features (snapshotting, RAID, encryption, bitrot protection) without you having to combine and manage several different technologies (mdadm for RAID, LVM, LUKS, ...). I did that on my main rig and it turned out to be rather complex. Hence the switch to btrfs to at least squash a bit of complexity.
If you'd rather continue working with the storage technologies you know and avoid zfs, you may want to look into other OSs than TrueNAS (because that is zfs only). Two I'm running and can recommend are
