Hello! I'm in the process of migrating from Synology to Unraid. I'm also slightly reorganizing.

My Synology setup had 2x18tb RAID1 HDDs in BTRFS.

I've degraded the raid, put one of the drives to the new NAS where I'm setting up a new NAS with 7.2.4 Unraid on it. Then I wiped the drive, created new ZFS pool from GUI. After that I created a secure smb/nfs share called SHARE again using GUI.

Then I decided that I want several nested datasets. I installed the ZFS Master plugin and created some nested datasets with mountpoints inside the parent SHARE dataset.

At some point I noticed that Windows no longer reports used space on the mapped network share (\\ip\SHARE) authenticated with custom credentials. The share itself is secure. I think, at one point it did show everything properly but now it doesn't. At the same time I have another pool with a dataset without the nested datasets. This does show proper info. Another weird thing is that the total available space shown in Windows is actually the free space. So when I'm gradually filling this dataset using mostly nested datasets, I see the total space shrinking. Looking more closely, something weird happens with Unraid GUI too. Check out different "free" metrics.

Am I correct in assuming that the only proper fix is to remove those nested datasets as they seem to be unsupported by Unraid? On the screenshots below 192.168.3.60 is the Synology with the exact same drive that's sitting in the Unraid 192.168.3.61

Unraid's perfectly fine with them, samba maybe not so much. Shouldn't cause any actual issues other than having to check for space on the server itself.

Alright, thanks for the heads up! Will keep them for the time being. I love the granularity they give me with automated snapshots.
