Need Strategy Advice on Setup of a Dataset for SMB Windows Share

Hello,

I am setting up a brand new TrueNAS Core system. It will be used as a File Share server for a main Server (Win 11) and several smaller PCs at home (some Apple OS as well) as well as movie and media libriary.

Chassis is TRUENAS-MINI-3.0-XL+ and it has 6 / 20TB disks which I have merged under a single pool, configured as RAID-Z2 (2-drive fault tolerance), which effectively gives me 72 TB of available storage.

I currently have 8 internal drives in my old Win 10 Server machine with I would like to transfer onto new NAS storage and create stand-alone buckets of storage that will correspond 1:1 to my internal drives. After that I will decommission my old Win 10 server and connect NAS to a new powerful Win 11 machine which will replace the old one.

Question: Since I have only 1 single pool of 72 TB, is there a way I can create several separate datasets of smaller sizes (i.e. 5TB each) to SMB mount them to a Windows machine? I would like to have separate datasets for media / movies libriary, separate for for a business purpose and separate for photo-editing.

When I attempt to create a new dataset, it by default takes the entire space of the Pool which I had created (72 TB).

I don’t see an option to specify a smaller size for a dataset. Do I need to use “Quota for this dataset” and Quota for this dataset and all children parameters to limit its size to desired 5 TB ?

P.S. I considered using iSCSI but don’t want to do it because it’s not a critical for me to have a transactional speed for writes to disk and setup of iSCSI is more complex. The recovery and maintenance of files in the file systems is also more of a concern with iSCSI.

Yes you got it. Quota for dataset and children will also include snapshot space.

Simply create your datasets to segregate your data and make a share per dataset and apply a quota to each dataset for your desired outcome.

Thank you!

A quick off topic question if I may - how do I configure my profile to list the system specs as you and many other have (the clickable arrow that expands)? Looked across profile options and don’t see where I can enable this.
