My main issue with their system is how closed it is.

I got an issue where mind would randomly start writing disk like crazy and maxing cpu usage, to the point I was bothered by the noise. I’d stop all containers, leave it as close to idle as I could manage, still spiking.

There was no way I could learn what was causing it.

I would like to assume it was a disk maintenance process or something, but for all I know it could be mining bitcoin and I’d be none the wiser. It went on for some weeks then stopped.

Ever since they added the "universal search" thingy, their NAS do that anytime they reach a decently large video file. Even if you turn down search indexing, media indexing, media thumbnails, ... It still kills itself with no throttling processing those files.

May or may not be what you encountered, but had a customer caught by this and found out the hard way you can't stop it. My issue is not the processing, it's the throttling, it's so crazy how the entire NAS gets taken down for like ten minutes (and that was on a racked xeon model), no samba no nfs no nothing answering anymore.

That might be it, I use it for radarr/sonarr so there’s a good amount of large video files in there.

And yes, the lack of trotting is an issue, since you can’t even reach an administration panel. When it’s bad even ssh struggles.

Mine is in the basement for this reason. When it’s still and quiet after midnight I can still hear it grinding away. God I hate the sound.

There are guides on how to mainline Synology NAS's to run up-to-date debian on them

https://forum.doozan.com/list.php

People seem very attracted to Synology because it requires very little thought & effort.

FWIW the new Ugreen NAS run Debian. I don't know a ton about it, but it's be great if they could stay a little more up to date. This Synology story with ancient forks & weird encryption sounds truly bogus.

I'm attracted to them because you can find them secondhand on ebay for very cheap, and their power draw / performance ratio is quite decent compared to other systems.

I will say that the Ugreen NAS seems to offer more performance for less watts, so it's definitely something I will keep an eye on in the future if it pops up on Ebay.

It's not. My Synology is running Linux kernel v4, and I opted to use their "SHR" RAID configuration and can confirm that it's some weird BTRFS variant that is likely deadlocked due to the kernel.

The encrypted volumes I've made also look very much like the EcryptFS files I've been seeing on other setups.

I'm currently in the process of mainlining it to kernel v6 to reap the better power and idle / hibernation rewards, as well as just using a standard Ext4 FS with updates

SHR is mostly MD-RAID and LVM, and works with ext4 too.

I have a Ugreen, just got the latest update runs on kernel 6.12

If you want to run Debian instead of DSM, you have a much wider choice of NAS hardware than just Synology.

You could activate the sshd service and log in to the NAS.
