After installing omvextras like described here http://omv-extras.org/simple/i…install-omv-extras-plugin its in the menu!
Btrfs/ZFS support
-
- OMV 1.0
- fulgas
-
-
omv-extras installs the kernel headers required for compiling the zfs module.
-
My VM omv-extras was being held for upgrade. Don't know why, just purged and pick the new one. This time it requested apt-transport-https, was it always dependent on this or is new ?
-
-
That is new. The nzbdrone repo uses redirected https apt repositories so it needs apt-transport-https.
-
ah that's why i was missing it yesterday. Thanks, now the drone appeared
-
Next Problem:
I have 4 Disk in my zfs pool (2tb,2tb,2tb,1tb) in 2 Days i want to replace the 1tb with a 2tb. I put it in to create a RAIDZ. On a raidZ i can replace a Disk, but i can't add a new Disk. So i put 4 disks in for now.My pool now have 3,62 TB. I learned for OMV i need to create a Volume or a Filesystem. This Filesystem has a maximum of 2,59tb. Same with volume.
What is the Problem? - Or is there a Problem? What will happen when i replace the 1tb? -
-
What will happen when i replace the 1tb?
Don't know what would happen in ZFS, but in linux mdadm your raid array would go then from 3,62 (4TB) to 6TB. That's because the initial raid was created with a smaller disk.
It should be the the same....but that just guessing. You can always replicate the behaviour in a virtual machine -
Ok, but why i can only use 2,59tb of the shown 3,62tb?
-
And another problem:
NFS Share can't be created using ZFS Filesystem - CIFS is working.

I'm not sure, but this maybe helps: https://docs.oracle.com/cd/E26502_01/html/E29007/gbbti.html

Is fine. Is raidz (raid5 equiv)
The pool size is the sum of all disk
You have 4x1TB, the 2TB disk are reduced to 1TB. So for FS is (n-1) x size disk.
thats 3TB (~2.59TB)

What is the best practice to use zfs in omv? I only know it from freeNas. Simply create a pool an you can use it for Data.
In OMV i must create a Filesystem(ext4,XFS...) on a ZFS Volume. I this right? This makes no sense to me...

I am surprised, you realize we are in alpha, beta cycle for zfs right? I do seriously recommend you to start using this in a VM to have a better understanding of pools, snapshots, datasets and virtual devs. Take a look at the documentation at oracle and ZFS on linux.
I am just starting in ZFS with the plugin, but i would not by put a 6TB array on zfs now, unless of course I didn't care about what's inside. -
Sure i realized this. I thought i want to test this, but i see the zfs support is not working / unusable for now.

It is working just fine on my system...
I created one pool and multiple shared folders from that.
-
I can't replicate the error you posted, any spaces in the FS or pool name? is not allowed in the plugin but maybe you created the pool with CLI (i am not sure if in CLI is allowed)

I just reinstalled my OVM from scratch because I messed the NIC interfaces up (firstaid did not help) while trying teaming the NICS and again the plugin is missing in the GUI.
Install:
OMV ISO -> online upgrade to 1.1. -> install omv-extras -> ZFS repo -> install ZFS pluginMy ZFS pool went online direct after installing and is listed under "Filesystems" ist just theplugin that doesn't want to show up.
apt update doesn't show any missing updates. Any suggestions?

What's the omvextras version?
