Nobody with an idea here? What I actually want to do is: get Proxmox backup server running in a VM on OMV to better manage backups (incremental etc) for my Proxmox host.

Nobody with an idea here?

Hi, I am having difficulties to bridge my (only) eth adapter to the VM I created.

How should the config be in network section?

This is the only way I get a nic working, I can even ping out of the VM, but there is no route to the VM.

How can I bridge and get an IP from my router?

Thanks for all this support! As soon as I have any news I'll let you know!

Hi, I tried to do what you mentioned from console. (tried a couple times to wipefs) Here is also a more detailed error from webUI:

Error #0:
OMV\ExecException: Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; omv-mkraid /dev/md0 -l stripe -n 5 -N stripe0 /dev/sda /dev/sdb /dev/sdd /dev/sdi /dev/sdj 2>&1' with exit code '1': mdadm: chunk size defaults to 512K

Does this help?

EDIT: I tried to create RAID then wipe again, getting a weird message on one drive:

root@omv-temp:~# wipefs -a /dev/sda
/dev/sda: 4 bytes were erased at offset 0x00001000 (linux_raid_member): fc 4e 2b a9

root@omv-temp:~# wipefs -a /dev/sdd
/dev/sdd: 4 bytes were erased at offset 0x00001000 (linux_raid_member): fc 4e 2b a9

EDIT again as nobody replied yet:

Formatting the drive singularly right now so I am able to move my data from my Freenas.

Will then hopefully work better on the FN box

EDIT once more:

I managed to create RAID and encrypted volumes(?) on it with:

mdadm --zero-superblock /dev/sdX

echo 1 > /sys/module/raid0/parameters/default_layout

Then all seems to work fine!

Hi there, I just created a temporary OMV with some old HDDs to save all stuff for the installation of my main NAS.

Important stuff is backed up already, but lots of big files ~9TB need a temporary NAS...

Now I wanted to create a RAID on the temp NAS but get this error:

Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; omv-mkraid /dev/md0 -l stripe -n 5 -N asd /dev/sdj /dev/sdb /dev/sdd /dev/sdi /dev/sda 2>&1' with exit code '1': mdadm: chunk size defaults to 512K mdadm: super1.x cannot open /dev/sdb: Device or resource busy mdadm: /dev/sdb is not suitable for this array. mdadm: super1.x cannot open /dev/sdd: Device or resource busy mdadm: /dev/sdd is not suitable for this array. mdadm: super1.x cannot open /dev/sdi: Device or resource busy mdadm: /dev/sdi is not suitable for this array. mdadm: super1.x cannot open /dev/sda: Device or resource busy mdadm: /dev/sda is not suitable for this array. mdadm: create aborted

Any hint here?

Thanks!

Thanks for the hint! Will backup all data, then see what to put where

So that one should work then? Sounds good! So a setup that is typically seen also on Ubuntu, with LVM -> LUKS -> Filesystem?

Just read about the plugin here on the forum.

So it's time to swap system these days! Thanks for all the input!

mdadm sounds like a good way to go. Also encryption is easy to implement here?

Then I'll get some big HDDs and copy off all stuff from the current FN setup and start fresh with OMV

Thanks for the quick reply!

The thing about ZFS: I don't necessarily need to be on ZFS.

What is the default technology used by OMV? How is it handling the (SW)Raid?

Hi there, after lots of issues with FreeNAS, after being annoyed of not having the remote shell I am used to from Linux systems, and much more...

...I am thinking of switching my NAS at home to OMV.

Now a big thing ahead: I want my stuff to be encrypted. There seems to be a plugin for that in OMV? I did not find a guide to create the volumes with encryption though?

Any link would be nice here.

About RAID: I have raidz-2 right now, so raid5 would be corresponding. As FN uses the raid card in IT mode, it should be the same for OMV I suppose?

Lots of questions, maybe some are answered already? Sorry for not finding them at this point...

Best regards

David

Thanks a lot, that worked!!

Thanks for the reply.
I already thought it must be encrypted folders. But then they must be like a split archive?
So it does not reflect the typical setup you would do for encrypted storage on OMV?

Are more details needed? Or does anybody have an idea?

Hi Folks,

I was in a coma for some time, came back and figured out I have a server Cool!
Passwords also are no issues to remember (luckily).

The only issue is I don't remember how the storage was set up.

I see in the GUI a ZFS volume with 6 disks, which is all right. The volume is mounted on /pool0.
If I look into /pool0 there are ~8 files with names like ECRYPTFS_FNEK_ENCRYPTED....

Any info on how to get access to my data?

I have a script to mount storage which is referencing to /dev/sdx but that does not work, the system says it does not find the devices (which are there of course)

Of course I can provide more details once I am at home!

Thanks
David
