Can I make a script with "echo 2147483648 >> /sys/module/zfs/parameters/zfs_arc_max" and run it when array start? 

No idea about what you're talking about, but you can run a script at array start via the user scripts plugin

i need to limit zfs ARC-cache size

I'm trying to do as it is written in the first post, by adding line in go file, but this doesn`t work =(

limit the ARC to 8GB with these two lines in my go file:

Probably because at the time of "go" execution, the plugin isn't loaded yet.  user scripts should do the trick

user script worked! Thanks!

I posted in the wrong forum earlier in the general support... I read this article  from google and it didn't help me..  but here is what a I wrote

"

I been googling  how to import the zfs  I  installed a zfs plugin  I figured just a plug and play nope 

then I read you  you type 

zpool import -f Poolname

but that did nothing file not found

 

is there exact steps to import the disks so I can copy it to the new hard drives then wipe the zfs format

like detail steps be good"

The plugin should import all zfs pools. But you could try manually: zpool import -a

well I restarted over reformatted my usb and reinstalled unraid..  and I re ran that plugin  but how you know its working 

I have now showing my 3  freenas drives  under unassigned devices   but I don't see a file share name to access these drives I thought I could just do add share  and point to the drives  but that isn't working..  

if it shows up  in unassigned devices  is it imported?    and how do I access them  whats the next step?

I typed in zpool import -a   but I haven't seen a change  that I can access the files  

and I got this from typing in that code

cannot import 'mediaserver': pool was previously in use from another system.

The pool can be imported, use 'zpool import -f' to import the pool.

so do I do that -f    but will that let me access the files

 

and I new to this Linux stuff unraid freenas stuff.. im been a windows user over 30 yrs  so im used to windows shares  etc  so like a file folder  and just copy or move  drag and drop

so I ran the 

zpool import -a 

then 

zpool import -f   

like it told me to

it printed "

but I still don't see a file folder share  of the 2 datasets 

nothing I can double click on the network share of the unraid server  I see the isos appdata etc folders but no mediadrive2 or sdc folder

how do I add those  so I can drag and drop the files to unraid

 

Doesn't zfs place the pools at "/" when at they are mounted? /Tank, /rpool etc.

I dunno  I guess  but I I cant make a unraid share  specifiying  share name "root"  file location "/"   

it doesn't allow me to set where the shares go  

so I don't know how to access it if I cant share the folder

First make sure it's there at /. Use terminal to make sure it's there. Set the mountpoint using zfs cmdline.

zfs set sharesmb=on "poolname" to share using samba. Your not going to be able to do much of anything in the GUI.

Sent from my SM-G955U using Tapatalk

This is a console only plugin that does not tie into the unraid shares. If you want the data to be shared over samba you have to manually edit the samba config. You can see the mount point of the data using zfs list

ok so I tried this in the unraid terminal

zfs set sharesmb=on mediaserver

it then was trying to share all the root folders but it cant

does this for every root folder on the mediaserver

and how you set the mount point for zfs /   

I not much a terminal person..

is there a program  to access these files

how come I cant see root folders of unraid either  in samba shares

I found another article with using  FileZila  with SFTP  what ever SFTP  is   I connected didn't even need a port

but couldn't use my root account..

 

but I see the mediaserver folder

how come I cant see these other folders  in unraid  like disk 1 disk 2 disk 3  of my unraid

 

@comet424 go to terminal, then type mc,  you can see your pool there if it is mounted

to see mountpoint use "zfs list" comand

root@unRaid:~# zfs list
NAME      USED  AVAIL  REFER  MOUNTPOINT
zfspool   127G   322G   127G  /mnt/zfspool

 

to add share go to Settings - SMB and add something like this to SMB Extras

[Backup]
      path = /mnt/zfspool/Backup
      comment =
      browseable = yes
      # Public
      writeable = yes
      read list = 
      write list = 
      valid users = 
      vfs objects =

this worked for me, i am new to zfs. Some days ago i created my first usb mirror pool for backups. will see how it go....

Edited July 7, 20187 yr by vanes

that MC program is cool  I could see the files   I couldn't get the File Options on top  I thought ALT would do but nope

and the SMB share  in unraid I looked I cant add all those features   I cant choose a path.. heck cant even uncheck  off samba …   all I can do is add shares under shares but u cant specifiy a specific location..

unless I need to turn something on or off to get that feature

 

I tired of ZFS  when I delete files or move them... ZFS  uses more data so even though I moved say 300gig off the freenas zfs  it still increased the used data  so  it didn't minus 300gb  just kept addng up  so got fed up with that  and the crap of plex with it doesn't work right..  rsync  didn't work way I was hoping number of things

MC full features don`t work in browser. Try use ssh client like Putty

 

to share my Backup folder on my pool ( mounted /mnt/zfspool )i added

Hey all, anything I should be aware of regarding folder permissions when using ZFS on UnRAID?

 

I've moved my docker's appdata folder from /mnt/user/docker to /zfs/docker (using the ZFS plugin to create a zpool outside my array):

root@NAS01:~# zfs list

I restored my CA Backup of my docker appdata folder, and it seem to have kept all my permissions in place:

(obfuscated the folder names)

 

Yet when I move my docker volumes from /mnt/user/docker/xyz to /zfs/docker/xyz, the containers have all sorts of permissions issues writing to their config folders. For example, Plex won't start, UNMS throws permissions errors on its config folder, etc. I can't find any differences in UID/GIDs between the two docker folders, but every container I've tried so far has the same issue.

 

Any thoughts on what I'm missing?

I ran into some problems until I moved my zfs mount folder from /SSD to /mnt/SSD

I think there are some hard coded requirements that folders start with /mnt

Trying this out. Will report back findings. Thanks!

No dice set it to /mnt/docker as my ZFS mountpoint, and I still get permissions issues.

 

Here's my zpool setup and transfer of CA Backup to the new pool - maybe something I need to add/change in this? I stop docker prior to the configuration, change where my docker.img file is located in unraid settings, then start it up after the process.

 

zpool create docker -m /mnt/docker mirror scsi-350000393a819195c scsi-350000393a8195a74 mirror scsi-350000393b82b5d94 scsi-350000393b82b6a2c

zfs set compression=lz4 docker
zfs set atime=off docker

tar xzvf /mnt/user/backups/docker/2018-09-12\@03.01/CA_backup.tar.gz -C /mnt/docker/
cp /mnt/user/docker/docker.img /mnt/docker/

 

I was able to resolve it by running  chmod 777 /mnt/docker/*

Unsure why this works while the /mnt/user/docker one has all the non-777 perms, but that's fine. I should probably someday go back and find out what's going on, but for my Plex server, it doesn't matter that things are 777.

 

Thanks!
