SCALE | Syncthing inotify Limits

[N20Visuals]

Hi all,

i'm finally gotten around to set up another container after migrating from CORE to SCALE.
This time, syncthing. After fiddling with permissions now everything is working well, but i do have one problem:

Code:

"Cloud" failed to setup inotify handler. Please increase inotify limits, see https://docs.syncthing.net/users/faq.html#inotify-limits

inside the container the command doesn't work, so i'm wondering after reading this thread:

that i might have to increase this limit within scale itself. is that possible and if yes, should i do it? or do i risk instability or even worse issues?

on another note, is it possible to run every container as a different user to be able to give more granular access to the file system? now i have to grant all apps access to my folder, kinda unsafe...?

thank you for you help :)

It depends on the app. Most (all?) TrueCharts apps have a few fields for this:

runAsUser
runAsGroup
fsGroup

It is advised not to change runAsUser or runAsGroup because it could break the functioning of the app. Though, I've changed runAsGroup in a few apps and it didn't seem to hurt anything. May be case by case.

You can make the permissions as granular as you want by making new groups in TrueNAS and using their GID number in the fsGroup field.

ah, thank you for that :) i installed the official container, there is no fsGroup setting. maybe i'll try changing to the truecharts variant.

just to clarify, so when "my" folder is owned by user 1000 and group 1001 then fsGroup for Syncthing should also be 1001?

Yes. That should work provided that you also give group 1001 the expected permissions [for your folder].

System Settings -> Advanced -> Sysctl

Var​	Value​	Enabled​	Description​
fs.inotify.max_user_watches	524288	true	Increase inotify limit

This is standard 'Linux stuff' so feel free to read up on this setting in detail. You might have to adjust this number to your needs, i.e. lower or increase it pending your number of files/folders scanned by Syncthing.

If you have at least one truecharts app, it automatically increases that to 524288

@stavros-k: ah, good to know, i've now increased the limit manually, might have not needed it but anyway :) everything is doing what it's supposed to now, thank you.

To be clear: this is not the case anymore.

I just updated to Bluefin and had to delete and then reinstall synchthing. I already have the inotify handler limit manually set - following your post exactly and I'm still getting the error. Everything seems to be working fine - is something I should worry about? I don't understand why I'm still getting the error.
