I just setup a new NAS and wanted to create a RAID 5 with 4*14TB harddisks.

You should really think about if a RAID5 array created with 14 TB disks is still an appropriate way nowadays. If you had to replace a disk in the future the resilvering process takes forever and entails the risk that a second disk fails. Which then means a complete loss of the array.

So I deactivated two harddisks and created just a stripe RAID (RAID 0).

You are aware, that RAID0 has no data redundancy? If one disk fails you lost the array. A RAID 0 is normally not useful in a NAS, especially with a GB Lan connection.

How do you want to organize your data backup system?

Reducing the partition size will not solve the problem if the method used clones the entire disk.

Clonezilla won't clone to a smaller disk
Maybe not possible with a direct disk to disk clone but by an image file? And another option has to be set "Resize partition table proportionally.

- I was not able to clone the 275GB (not 256GB btw) drive to the 240GB new drive

You could also try to reduce the partition size of the source disk from 275GB size to e.g. 235GB that it fits to the new destination disk, before the clonezilla image or disk clone is created. And thereby use the -icds option as macom has suggested.

But I don't have nut installed, why omv does not remove all files/services during uinstallation of plugin?

This can only be answered by the dev.

How can I stop and remove all services releated to nut plugin?

systemctl stop nut-client

systemctl stop nut-server

and then

systemctl disable nut-client

systemctl disable nut-server

to prevent a start at the next boot.

Have a look at this threads:

• [Help!] Nut plugin - UPS-notifications are spamming my mailbox
• NUT 4.0.13-1] OMV keeps sending notification email with nut service off
• OMV-NUT plugin breaks email notifications on OMV5 #448

Maybe you can try to manually stop the nut services.

It seems OMV reacts sometimes a little bit picky if the UPS is not reachable by the NUT services when they are started by the plugin.

Do you use the nut plugin? I have determined that there is a relation between notification errors and the nut plugin. The nut plugin reacts sometimes a little bit picky it the UPS is not reachable by the nut driver. You should ensure that the UPS is reachable by OMV and then try again to register the new email address in the notifications.

Maybe a syntax problem?

You should try to delete the striped raid array and use the two 500 GB disks in OMV as single disks. By the way with only two disks it is not possible to create a RAID 5 or RAID 6 array, only RAID 0 or RAID 1.

There are several possibilities in OMV to use the second disk as an backup storage for the first drive. And this process can be completely automated.

Look at this thread: ROCK 64 + OMV It should point you in the right direction.

I would recommend the UEFI installation simply because it is state of the art.

It is not expedient to update from OMV 3.0.99 to OMV 5. Principally you have to update to OMV 4 first and then in a second step to OMV5. But there are so many basic changes made in OMV5 (e.g. replacement of many plugins by docker solution), so that it is very useful to start from scratch with OMV5.

I would say, this is a problem of the ACPI settings. Google says that the Acer extensa 4420 has some problems when installing Linux on it. I read to set the ACPI off in the kernel parameters could be a solution. Kernel-Parameter: Starthilfe bei Linux-Inkompatibilitäten

Unfortunately, my system is set to German language, so I will provide some screenshots rather than guessing the exact translation to each setting.

If you want to create screenshots in another language you can switch quite easily the language settings in the OMV WebUI temporarily.

Not available

What do you mean with "not available"?

As raulfg3 has suggested did you try to import the pool with the force (-f) option?

CLI> zpool -f import extra

What is the output of the commands zpool list and zpool import?

There is a German Website with an overview and comparison of several tools to read (and write) Linux file systems / partitions in Windows. Generally there a more tools to read linux partitions than to read and write.

Link: Linux-Partitionen unter Windows

There a several browser extensions or other possibilities to translate web sites.

You should append a screenshot or a picture of the incident at least.

I found an older thread here in the forum where ryecoaaron has suggested to install debian from the netinst iso first with a mirrored boot device scheme then install OMV on top.

Quote from Remrem

When I do "nslookup" I get the message "command not found"

I would say nslookup is a part of the dnsutils. Therefore you have to install them first. See post #15. Which is not possible as you have already mentioned => Deadlock.

Quote from lotsofbytes

Therefore I'm wondering if it's possible to do the installation on two ssd's in a mirrored zfs pool?

As I know this is not possible. It is possible to use ZFS for the data pool but not for the OMV installation itself.
