FreeNAS: Permission problems when populating datasets as root (cli)

I'm setting a home NAS taking it as a chance to get familiar with FreeNAS **My specs**: FreeNAS-11.3-U2 Intel(R) Core(TM) i5-4690 CPU @ 3.50GHz. 16GB DDR3 RAM. OS: runs on a SSD ADATA SP600 250GB. **My Pools**: 1) NAS01. /mnt/NAS01 **2x 2TB Mirror** w/ 1 spare (the real backup/NAS space). The 2 dev of the mirror are WDC WD2003FZEX ; the spare is a ST2000DL003 2) S500. /mnt/S500 **1x 500GB** (scratch space). The disk is a ST3500320AS There is also a 6th 1TDB disk waiting to be used... I originally backed up some 80GB of data from another computer into an zfs dataset on an external HD. Only after that I learned such a disk can't be imported. This dataset had a snapshot created in that original computer. I then managed to transfer the dataset into pool2 as S500/pre2012 mounted on /mnt/pre2012 (honestly, can't remember exactly right now how I did it by, but must have been through cli via zpool and ifs). At some point I used a zfs send | recv to transfer (can I say copy?) S500/pre2012@snp1 to pool1 under NAS01/pre2012 -which unexpectedly to me was mounted under /mn/mnt/pre2012. After testing and getting somewhat familiar with SMB shares and checking I could have it working with all my MACs & Linux boxes I decided it was time to organize pool 1 (NAS01) into different datasets according to what I'm planning to store and how to use it. I created these datasets using the GUI. **The result is the following structure of root datasets (as per zfs list)**: NAS01/PRIVATE 55.0G 1.62T 20.5G /mnt/NAS01/PRIVATE NAS01/PRIVATE/Documents 573M 1.62T 573M /mnt/NAS01/PRIVATE/Documents NAS01/PRIVATE/Fotos 33.9G 1.62T 33.9G /mnt/NAS01/PRIVATE/Fotos NAS01/PUBLIC 16.9G 1.62T 96K /mnt/NAS01/PUBLIC NAS01/PUBLIC/Library 57.6M 1.62T 57.6M /mnt/NAS01/PUBLIC/Library NAS01/PUBLIC/Movies 15.5G 1.62T 15.5G /mnt/NAS01/PUBLIC/Movies NAS01/PUBLIC/Music 1.05G 1.62T 1.05G /mnt/NAS01/PUBLIC/Music NAS01/PUBLIC/Software 299M 1.62T 299M /mnt/NAS01/PUBLIC/Software NAS01/pre2012 71.3G 1.62T 71.3G /mnt/mnt/pre2012 S500 268G 178G 136K /mnt/S500 S500/SharedScratch 196G 178G 196G /mnt/S500/SharedScratch S500/pre2012 71.4G 178G 71.3G /mnt/pre2012 SharedScratch has been working well under SMB in my network -while I used only guest account access and nobody:nobody ownerships. But that's another story. Currently, the **structure of S500/pre2012** ( or rather that of of its mount point) is: /mnt//pre2012/120/30/home/ /mnt//pre2012/120/30/MatLab6.5/ /mnt//pre2012/120/80/home/ /mnt//pre2012/120/80/O/ /mnt//pre2012/120/80/usr/ /mnt//pre2012/250/48/home/ /mnt//pre2012/250/80win/ It also had other folders like Music that I managed to mv (not w/o quite some pain) to NAS01/PUBLIC/Music, say. All these folders under S500/pre2012 are owned by user admin. It's the only additional user I created. **My problem seems to be related to privileges issues, although I sudoed into root when issuing commands like the following**: root@freenas[/mnt/S500/pre2012]#mv 120 /mnt/NAS01/PRIVATE/Documents mv: chmod: /mnt/NAS01/PRIVATE/Documents/120/30/home/msantos/Reports/Apoptosis: Operation not permitted mv: chmod: /mnt/NAS01/PRIVATE/Documents/120/30/home/msantos/Reports/.Designability.March.2005.tex.swp: Operation not permitted mv: /mnt/NAS01/PRIVATE/Documents/120/30/home/msantos/Reports/NMR: File exists mv: /bin/cp 120 /mnt/NAS01/PRIVATE/Documents/120: terminated with 1 (non-zero) status The **folders' permissions** are: root@freenas[/mnt/S500/pre2012/120]# ll ; ll /mnt/NAS01/PRIVATE/Documents/120 total 26 drwxr-x---+ 4 admin admin uarch 4 Sep 22 21:03 ./ drwxr-x---+ 4 admin admin uarch 4 Sep 22 21:03 ../ drwxr-x---+ 3 admin admin uarch 3 Sep 22 21:14 30/ drwxr-x---+ 5 admin admin uarch 5 Sep 14 15:56 80/ total 2 drwxrwx---+ 3 root admin uarch 3 Sep 22 21:57 ./ drwxrwx---+ 3 admin admin uarch 4 Sep 22 21:57 ../ drwxrwx---+ 3 root admin uarch 3 Sep 22 21:57 30/ As you can see the move failed to copy everything, although it did copy something! That's even more worrisome bc it's a move! Here some **permissions of destination folders**: root@freenas[~]# ls -lF /mnt/NAS01 total 9 drwxr-xr-x+ 5 admin admin 6 Sep 22 19:16 PRIVATE/ drwxrwx---+ 6 root wheel 6 Sep 22 15:30 PUBLIC/ root@freenas[~]# ls -lFd /mnt/NAS01/*/* drwxrwx---+ 3 admin admin 4 Sep 22 21:57 /mnt/NAS01/PRIVATE/Documents/ drwxrwx---+ 15 admin admin 19 Sep 22 20:37 /mnt/NAS01/PRIVATE/Fotos/ drwxrwx---+ 2 nobody admin 4 Sep 22 21:03 /mnt/NAS01/PUBLIC/Library/ drwxrwx---+ 5 nobody admin 38 Sep 22 20:13 /mnt/NAS01/PUBLIC/Movies/ drwxrwx---+ 17 nobody admin 36 Sep 22 20:41 /mnt/NAS01/PUBLIC/Music/ drwxrwx---+ 9 nobody admin 9 Sep 22 21:09 /mnt/NAS01/PUBLIC/Software/ All those children datasets of PRIVATE and PUBLIC are being shared via SMB. The first one should only be accessible to admin user. Hence those permissions/ownerships. **My questions: How can I reliably use mv here to populate these datasets?** I don't understand how to use zfs send/ recv to copy data into a specific datasets/folder. That's why initially when I tried I ended up with a copy of pre2012 under /mnt/mnt/ which the GUI doesn't let me use as a share. Hence my using mv. **Furthermore, since I'm trying to sort different folders of the original dataset into different dst datasets, I can't see how zfs send/recv can do that. Is that possible?** I'm a bit frustrated at this point. Either I did things totally wrong or I'm missing a fundamental idea of how FreeNAS is supposed to be used...or both :-/ In any case, I didn't expect that populating the server with data would be so complicated. Again, this is just after my first 1.5 weeks in toying with FreeNAS. Sorry for the lengthly post. I'm stuck right now. Any hint will be appreciated. Thanks in advance.
