After my SD card boot drive corrupted for the last time, I went hunting in local markets for a cheap, permanent fix for my budget server (Zebronics G41 / Core 2 Duo / 6GB RAM running TrueNAS SCALE 24.10).

​Managed to pick up an Intel 313 Series 20GB SLC SSD with hardware Power Loss Protection (PLP).

​Hooked it up and checked CrystalDiskInfo:

​Total Host Writes: Only 49 GB (practically brand new)

​Power On Hours: 4,625 hours

​Health: 100% Good

​TrueNAS SCALE installed cleanly, taking up only 2.77 GiB of the 18 GiB usable space, leaving ~15 GiB free for logs and future boot environments.

​Moving the OS/middleware dataset from an SD card to enterprise SLC flash over SATA instantly eliminated random Web UI delays and made SMB directory browsing surprisingly snappy. Definitely one of the best budget upgrades I've made for this setup!

TrueNAS is the first time I have to deal with ACL, aside from the simple version Synology had.

And either I am doing something wrong, or TrueNAS is messing up.

I have a SMB Share that I want to only give access to a few accounts, and deny Reading,Writing and everything else to everyone else.

For that, I created a "SMBDaten" Group, that holds these Users.

But adding that Group, and selecting that Group with Read, Write, Execute permissions, is not working.

I merely get a Error about POSIX requiring a Mask Entry? It did not need that before I added this group, so I have no clue what it is.

Ive also seen people talk about POSIX and NSFv4, from what I a seeing in the settings, my Dataset Inherits, and the root Dataset is having POSIX that I cannot change?

Additionally, I simply do not understand what the User/Group/Other Objects mean compared to the default ones?

I tried to read the TrueNAS Documentation and watch a few videos, but none of them really help me understand this.

If someone can help me understand, thatd be great
