hi i am new at zfs but have managed until this point. I have zfs pool set upand a mountpoint to an unraid shere but every time I restart the server my data disappears. but in the command line it stil says it is mounted at that location. 

can someone please help me

 

I don't know what method people are using to try and have Unraid's own array system mount ZFS shares, but I don't believe that is supported.

 

If you're happy to have an open share you can add something like this in /boot/config/smb-extra.conf

 

[sharename]
path = /mnt/poolname/dataset
comment = share comment
browseable = yes
public = yes
writeable = yes

 

(edit: ZFS support is coming to Unraid soon and presumably this will include creating shares in the GUI for ZFS pools/datasets)

I was wondering if it is possible to change the arc size. If Yes how would you do that

With that little information, no.

 

Please post your Diagnostics.

The word diagnostics wherever it appears in the forum is a link explaining how to get diagnostics.

Does the pool have a mountpoint configured?

 

zfs get mountpoint poolname

The plugin and also the module is installed and loaded successful from what I see from your syslog.

 

Did you create your Zpool like in the tutorial from the first post?

No I didn’t. I imported it from truenas

I think the issue lies here within the custom version from ZFS for TrueNAS, I could be really wrong about that but maybe someone like @BVD or @Marshalleq can help here.

I would suggest mounting your ZFS pool elsewhere, ie. /mnt/poolname

 

/mnt/diskx is where Unraid mounts disks for the Unraid array.  Seems likely that is the problem?

Yeah, you should not be doing that.

This was indeed the problem. thank you

Greetings, I'm a newbie to unRaid and wanted to try zfs with it. I used Spaceinvader One's guide as well as Linus' and Gamer's Nexus guide on YouTube to setup my server.  I thought it went well until I noticed that my data is being stored on disk 1 (the unraid array) and not my zfs pool.

When I copy files from my PC to the share on the server, the copied files are stored on the unraid array and not on the raidz pool.

My apologies if I get the zfs terminologies wrong... as I said, this is all new to me.

I'm stuck in a loop trying to figure this out but I some times I get tunnel vision and can't see the answer.

I guess what I'm trying to say is the user shares are not on the zfs pool.

I have attached my diagnostic file for your convenience.

Any help would be appreciated, thank you.

 

Best regards,

 

X

Unfortunately, right now, there is no easy way to create shares on the pool; you have to deal with smb-extra.conf file; this situation should be solved on the upcoming 6.12 version; in the meantime these are my templates for pool shares (ssdnvme in this example)

 

Private Share
 

[example_private_share]
	path = /ssdnvme/example_private
	comment = My Private share
	browsable = yes
	guest ok = no
	writeable = yes
	write list = iker
	read only = no	
	create mask = 0775
	directory mask = 0775
	vfs objects = shadow_copy2
	shadow: snapdir = .zfs/snapshot
	shadow: sort = desc
	shadow: format = %Y-%m-%d-%H%M%S
	shadow: localtime =  yes
	shadow: snapdirseverywhere = yes

 

Private Hidden Share

[example_private_hidden]
	path = /ssdnvme/example_private_hidden
	comment = My Private info
	browsable = no
	guest ok = yes
	writeable = no
	write list = iker
	read only = yes
	create mask = 0775
	directory mask = 0775
	vfs objects = shadow_copy2
	shadow: snapdir = .zfs/snapshot
	shadow: sort = desc
	shadow: format = %Y-%m-%d-%H%M%S
	shadow: localtime =  yes

 

Public Share

[example_public_share]
	path = /ssdnvme/example_public
	comment = UnRaid related info
	browsable = yes
	guest ok = yes
	writeable = yes
    write list = iker
	read only = yes
	create mask = 0775
	directory mask = 0775

 

Best,

Thanks for the info...

I'm just curious why in the video guides they don't mention the config file. Also, without sounding like a complete idiot; without the config file, how does one get their data on one's server?

This is what happens when you use Windows for 30 years!

The reason I'm asking is I'm trying to recover data from 16 drives that had a grey water shower when my septic tank back up and the data needs a new home. I'm building a second server to back up the first so I'm trying to figure out the best solution to protect 30+ years of photos and videos.

 

Cheers

I haven't watched any of the video guides, but this includes some explanation of what's going on in the above SMB (windows share) configuration examples:

One thing to consider is something like borg to backup your data offsite

I'm going to start over and try again with the new information!

ps: if you're still looking to build a second server for backups, probably the best option is sanoid to manage snapshots of your main ZFS pool, and syncoid to pull/replicate those snapshots on your backup server.

 

I have this setup so that on startup, my backup server will replicate snapshots from my main server, send an email summary and then shut itself down.

I was able to import my ZFS pools from Scale, which is awesome. Only question is what storage-driver is being used (i'm pointing docker directory and docker appdata at a NVME I have under ZFS). Typically I would edit the /etc/docker/daemon.json to make it look like this, however there's nothing in /etc. How does this work in Unraid, where is the daemon.json or equivalent? How do I set it to use overlay2?
