I’ve used (and still use) UnRaid before but switched to Synology for my data a while back due to both the plug-and-play nature of their systems (it’s been rock solid for me) and easily accessible hard drive trays.
I’ve built 3 UnRaid servers and while I like the software, hardware was always an issue for me. I’d love a 12-bay-style Synology hardware device that I could install whatever I wanted on. I’m just not interested in having to halfway deconstruct a tower to get at 1 hard drive. Hotswap bays are all I want to deal with now.
I have an unraid on a usb stick somewhere in my rack, but overtime it started feeling limited, and when they began changing their license structure I decided it was time to switch, though I run it on a Dell r720xd instead of one of their builds (my only complaint is the fan noise - i think 730 and up are better in this regard)
Proxmox was also on my short list for hypervisors if you dont want TrueNAS.
I have found workarounds for the read-only root file system. But they aren't great. I have installed Gentoo with a prefix inside the home directory, which provides me with a working compiler and I can install and update packages. This sort of works.
For running services, I installed jailmaker, which starts a lxc debian, with docker-compose. But I am not so happy about that, because I would rather have an atomic system there. I couldn't figure out how to install Fedora CoreOS inside a lxc container, and if that is even possible. Maybe NixOS would be a another option.
But, as I said, for those services I would rather just run them in Proxmox and only use the TrueNAS for the NAS/ZFS management. That provides more flexibility and better system utilization.
The deprecation caused me to move to something more neutral and stay away from all 'native' apps of TrueNAS and migrated to ordinary docker-compose, because that seem to be the most approachable.
I was also looking into running a Talos k8s cluster, but that didn't seem to be as approachable to me and a bit overkill for a single-node setup.
It isn't really the case. TrueNAS wants you to look at it as an appliance so they make it work that way out of the box.
On the previous release, they had only commented out the apt repos but you could write to the root filesystem.
On the latest release, they went a little further and did lock the root filesystem by default but using a single command (`sudo /usr/local/libexec/disable-rootfs-protection`), root becomes writable and the commented out apt repos are restored. It just works.
If it were now, I'd probably look deeper into Asus, QNap or a DIY TrueNAS.
I say "mostly" happy because I almost returned it. The USB connection between mini PC and Terramaster would be fine for a few days and then during intense operations like parity checks would disconnect and look like parity error/disk failure, except the disks were fine. Eventually realised the DAS uses power from the USB port as well as the adapter plug and the mini PC wasn't supplying enough power. Since attaching a powered USB hub it's been perfect.
Explanation of symptoms and solution, in case anyone is considering one or has the same problem: https://forum.terra-master.com/en/viewtopic.php?t=5830
It works well, but USB connection could be faster, and it bogs down when doing writes with soft-raid. I've been thinking about going for a DAS solution connected directly via SAS, instead. Still musing about what enclosure to use, though.
I will still have to come accross something like Hyper Vault for backup and Drive for storage that works (mostly) smoothless. I would be happy to self-host, but the No Work Needed (tm) products of Synology are just great.
Sad to see them taking this road.
