[ZFS plugin for unRAID]

To be honest I'm not sure I'm following you so much on the smb and security side.  Everything else was very well outlined though.

 

I think you're saying you use a link from zfs to the unraid share which to me sounds absolutely horrible.  So I only know the way I've done it, which is outlined below.

 

SMB permissions with ZFS are done manually via smb-extra.conf (which is in the /boot/config/smb directory).  The unraid smb GUI does not like anything outside of it's own array (I honestly don't know why you'd put in this artificial restriction, but they do) I've always preferred the console method anyway as it's more powerful.  So the point here being, you're using the same SMB system that unraid uses, but you're bypassing their artificial restriction of the GUI.  At least this is how I do it, someone else might have a better way.

 

Here's a typical one, then a more advanced one to help you out.

[isos]
path = /mnt/Seagate48T/isos
comment = ZFS isos Drive
browseable = yes
valid users = mrbloggs
write list = mrbloggs
vfs objects =

 

[pictures]
path = /mnt/Seagate48T/pictures
comment = ZFS pictures Drive
browseable = yes
read only = no
writeable = yes
oplocks = yes
dos filemode = no
dos filemode = no
dos filetime resolution = yes
dos filetimes = yes
fake directory create times = yes
csc policy = manual
veto oplock files = /*.mdb/*.MDB/*.dbf/*.DBF/
nt acl support = no
create mask = 664
force create mode = 664
directory mask = 2775
force directory mode = 2775
guest ok = no
vfs objects = fruit streams_xattr recycle
fruit:resource = file
fruit:metadata = netatalk
fruit:locking = none
fruit:encoding = private
acl_xattr:ignore system acl
valid users = mrbloggs
write list = mrbloggs

Also about the access denied, with ZFS on unraid you do have to go through and set nobody.users on each of these shares at the file level.  So basically

# chown nobody.users /zfs -Rfv

Who knows, perhaps this is all you need to do to get your method to work.

 

Good luck!

 

Thank you for that fast and informative answer  

 

I only followed the video guide on the link from zfs to the unraid share part: (timed where he shows this) https://youtu.be/umKXHO-hr5w?t=1850 if this makes more sense to you than it does for me

I guess since he did not have to worry about SMB security it just worked for him out of the box? I will look in to setting it manually as you have explained. Thanks

 

[ZFS plugin for unRAID]

Hi,

I do not know if I have put this in the right place.
Noob in unraid here trying to follow guides to set up my unraid server with zfs. Using the video https://www.youtube.com/watch?v=umKXHO-hr5w and this forum post. Thanks for making this! I had a test server set up, but formated the drives and deleted each partition using unassigned devices and unassigned devices pluss. I then installed the plugins: ZFS for unraid 6, ZFS companion and ZFS Master for Unraid. Since I have 32GB of ram i set 8GB to be used by ARC memmory as per guide:

"/boot/config/go" and "echo 8589934592 >> /sys/module/zfs/parameters/zfs_arc_max".

I have 1 ssd as a normal unraid drive.
I then created the ZFS Pool using 6 (8TB) HDD drives: zpool create -m /zfs zfs raidz2 sdf sdb sdc sdh sde sdd

I then set ZFS compression to lz4 as recomended with: zfs set compression=lz4 zfs

I then created datasets using: zfs create zfs/data and zfs create zfs/backup
Changed the compression on backup since it is going to be used as cold storage rarely used, using: zfs set compression=gzip zfs/backup

 

Checking the status with zpool status and zfs list, everything looks ok to me. Where my problem starts is when I want to use SMB to access the folders in windows using it as a network drive. I have earlier used this in unraid with a user I crated called admin with read and write rights and a user called user with read-only. This worked before zfs just fine ;).
Using the yt guide I created 2 shares with the names zpool and backup. I then typed in the command ln -s /zfs/backup /mnt/user/backup/backup and ln -s /zfs/data /mnt/user/zpool/data
The folders show up in the share and i set SMB to secure and the user admin to Read/Write and user to Read-only.

I then mapped the folders in windows using: \\TOWER\backup\backup and \\TOWER\zpool\data

 

So far so good, but the problem comes when I try to add files to these as I get an error message stating Destination folder access denied, You need permission to perform this action. Does the folder not inherit the user access set in the share? When mapping it as \\TOWER\backup it only show me the space from the ssd (drive1). When looking at the security tab in windows it shows: Everyone, root (Unix Group \root) and Console and WebGui login account (TOWER\root) all with just special permissions tagged. When adding admin as a user, using the "Check Names" function it finds TOWER\admin, but I get a error when applying security "Failed to enumerate objects in the container. Access is denied" and "unable to save permission changes on data (\\TOWER\zpool)(W:). Access is denied".  
Is there any way to get the subfolder to inherit the security setting set in shares?

Is there any other way to access the files in windows in the same manner?
If you see any other improvements to my setup, please do tell me
