    Thanks luxflow for your input.


    I tried what you and ryecoaaron suggested but it didn't work. :-/


    As alaways, I made a video so that you can see if I'm doing anything wrong :


    Did you create a zfs volume then a luks device on top of that and then an ext4 filesystem inside that? I don't have time to watch the video a bunch of times to figure that out. But either way, you can't resize the luks device with the luks plugin which means you can't resize (at least can't make bigger) a filesystem on that luks device.

    That is exactly what I did!


    So is there a way to resize a luks device at all?


    If there isn't, that means that the size I chose for the volumes will be the final size?


    I tried this (http://alittlestupid.com/2010/…how-to-grow-a-zfs-volume/) but as you can see in the very beginning of the latest video or the image attached, there is no mountpoint for the two volumes created.




    P.S : About the videos the longer one is 2min long :-)

    What problem? Resize has a very specific use case and is generally used for when a drive is added to a raid array. What are you trying to do? Maybe it is in the audio but I can't hear that.

    I just want, as shown in the video, to expand Media or Documents, give it more space.


    As I said before, I have no data on the volumes, I just wanted to try to resize the volumes in case I need it

    it seems likely omv-luks bug
    since omv-luks plugin recently is ported, there might be bug (it doesn't mean luks is unstable, but plugin for luks is unstable)
    I will check and fix and let you know (it will takes time <~3days?)

    Thanks you very much luxflow for you answer! I thought that I was doing something wrong!


    No problem I will wait.


    For now I shut the server down. I will not put any data on it till I'm sure that I'll will not face any software problem in the future while expanding or doing normal stuff with the drives.

    I don't have any speakers available to listen if there is audio on the video. If you are trying to unlock the encrypted volume, you can't while it is in use (referenced). This didn't change from OMV 2.x.

    Yes I figured that out later but it was not my main problem.
    In fact the problem occurs at 1:35 when nothing happens when I want to resize the volumes.
    (I don't have any data on the drives but in was a test to see if it works for when I'll need the feature in the future).

    Thank you very much luxflow for your patience!


    I finaly managed to go to the process succesfully. In fact it seems that there is a specific order to follow to do this succesfuly...



    But!...unfortunatly another thing went wrong...see here :



    Again, thank you very much for your patience! The only thing that keeps me sticking with OMV is that you and ryecoaaron keeps helping me otherwise I would have left for something more "noobie friendly" with plenty of documentations and a big community... :/

    I guess you can't use both. You could wait for the zfs plugin to support encryption or use mdadm raid.

    Thanks luxflow It worked!. (I had to remove the drives from the encrytpion area)


    But now encrypting those drive is not possible :



    So I guess there is no way to encrypt the drive and use them at the same time? :-/


    go filesystem -> create -> choose device -> ext4 -> mount -> go share

    Hi luxflow,


    Thanks for your answer. I created a 2min video to explain what I did and to show that I'm not able to do what you suggested :



    I hope that it will clarify what I want to achieve and the problem I have!


    Thanks again

    You totally right, I'll reduce the size for the volumes for now.


    So, I'm getting better understanding on how to slice the MainPool.


    Here is what I did :-MainPool 7.02 Tb
    ---Documents 1Tb
    ---Media 2Tb


    And that's great because now I'll also be able to encrypt the Documents and Media volumes. What about that dataset volume? Is 1Tb ok? what is it for?


    One last thing : when I try to create a shared folder in the Access Rights Management, the only Device it suggests me in the roll-up menu is the MainPool, It doesn't show me neither the Documents nor the Media volumes that I've created. Is that normal ? What's the point of creating volumes if we cannot use them? But I'm sure I'm getting something wrong.


    Thank you so much and thank ryecoaaron for your valuable help!


    Ok thanks for this valuable input, it makes things clearer.


    However, I did'nt get much of this sentence : "one guide line for dividing dataset(whether it is zfs filesystem or volume) is attribute for that dataset"


    So to be clear if I do this, is it clever? :


    - BigPool 7.02Tb
    -vol01 documents 1Tb (snapshot)
    -vol02 Media 3Tb (volume)
    -vol03 dataset 1To (volume) (don't know what it is for exactly and how much space it needs)


    I will be left with 2Tb not used. So if In a few months I see that documents needs more space, I'll be able to expend it, right?


    Also, in order to see all my data from my windows PC, I guess that I'll need to create at least one shared folder per volume right?


    Thanks luxflow for your input.


    Indeed it worked.


    When I did it I realised that I need some strategy first about how to manage my drives.


    So I have 3 hard drives of 4Tb actually 3,6 usable. After creating a RAID-Z1 pool. I'm left with 7.02 to use. For now it's more than enough.


    But how to I manage the volume creation? I mean, should I keep this master pool with 7.02Tb and share it entirely with smb / CIFS and create folders, or do I need to create one ZFS volume per need?


    For instance : a volume for /Documents, one for /Backup, an other for /Media?


    Thanks all for your patience. I'm really new to omv/NAS and everything. But I'm not in a hurry I can take time to set things properly :-)


    edit : in the case I need to create volumes, if a hard drive fails, I still can change it in a "plug and play" way?

    The order of the plugin installation doesn't matter but the order of the configuration does. While there are different ways to set this up, I would create the encrypted device(s) with luks first and then zfs on top of that. I haven't tried that to see if it works though.

    I think it's not possible de encrypt the drives and use zfs at the same time. When I first encrypt the drives, they are not being seen in ZFS. And when I create the pool first, it's not being seen in the Encryption area...


    No one has tried this before?


    Do I understand that there is no way to encrypt the drive while using ZFS?

    I'm having some trouble trying to install ZFS plugin here are the ERRORS :


    I watched this tutorial (even if don't understand a word @4:42) :


    I see that he has omv-extras installed and he can see ZFS repositories. I also installed the latest version of the omv-extras but I cannot see the zfs repository switches :




    I think that maybe the original tutorial of how to install ZFS is outdated and doesn't work for the latests versions of omv.


    Can someone help?


    Thanks a lot.

    Hi guys,


    I've very new (today new!) to openmediavault and its plugins


    So I've just downloaded and installed the luks plugin. How to make it encrypt my drives?


    I have an SSD where omv is being install and 3 unmonted 4TB drives.


    - Do I need to encrypt the drive where the system is installed? (SSD)
    - I think that I need to mount the 3 other drives to proceed but then how to encrypt the drive?


    Thank you all.

    Ok problem solved. (BIOS upgrade + some cabling :-D)


    OMV installed on SSD.


    Next step install luks plugin, followed by zfs plugin


    after luks plugin installation, I wanted to mount the hard drives, here is what I get :


    Can anyone tell me how to fix this?


    Ok now I know that it's not a problem coming from the SSD drive : I unpluged the SSD drive and tried to install Windows on one of the 4TB hard drives but Windows didn't see any hard drive pluged in.


    So the the SATA drives are not being seen.


    I think I may have a faulty motherboard

    Nope. Put the drive in a completely different system - desktop, laptop, whatever - and disconnect all other drives. Install OMV just like you were going to on your new hardware. After installing, take the drive out and put it in the new hardware. It should work.

    Noooooooooooo :D

    Ha ha! Don't worry it's temporary :-D


    Unfortunately I don't have any other system to put the drive on...the one I'm using right know is a Surface Pro 2 :-/

    That probably won't work. OMV re-formats it every time you install. Maybe the drive needs to be wipe? You can also install OMV on the drive in a different system temporarily. Then move the drive to the correct system and run omv-firstaid to fix the networking.


    I don't understand what you mean by "Install OMV on the drive in a different system temporarily"? You're talking about filesystem? Other than ext4?


    I think I'll try to install windows on it and see how it'll go.


    Also how come is the SSD drive seen as a SCSI5 drive? (see red screenshot above)
