TerraMaster Forum

Hello everyone,

I have bought the brand-new TerraMaster F2-425 Plus with TOS 6. I'm super happy so far.

I installed an NVMe in Slot 1. Then I initialized the NAS and selected the NVMe to install the boot loader, and afterward the operating system TOS 6. The NVMe is shown as a system disk. I was unable to install any software in this state.
Then I installed both hard disks and formatted them as RAID 1.

Now I'm not sure how to install apps on the system nvme?
I have found this topic here:
viewtopic.php?t=6213#:~:text=Post%20by% ... %20Support

This topic says you have to create a volume on the system disk; sdz4 has plenty of space left (200 GB).

But this does not work for me; when I want to create a volume, it's not possible, as the option is greyed out.
However, this person has a different NAS and maybe also a different operating system. Perhaps this makes the difference.

Can you help me or have any advice on how I can use the SSD for the system, operating system, and app software? I want the hard disks only to be used for storage files.

Thank you very much in advance

In general, the storage partitions on your NVMe SSD can be used as storage pools and volumes.
Have you customized the partition format yourself? This might be the reason why the storage pool cannot be created.
Please open Terminal and enter the following commands to check the storage structure:

Hello TMzethar, thank you very much for your prompt reply.

I have executed the commands

lsblk
pvs
vgs
lvs
This is how it is configured. However, I'm not sure if it is correct.
I am grateful for your help.

Thank you for your cooperation; it is much appreciated. However, the information provided does not show any details that might be related to the issue.
Could you please let us know the model of your SSD?Please enter the following commands again to check the information of this SSD:nvme smart-log /dev/sdzasmartctl -d nvme -iH /dev/sdza

Thank you very much GevinKe for your help. Its an excellent support here at terramaster, not usual today anymore.

However I have good news. I managed to solve the problem by myself.
First I installed the operating system on the ssd.
The I created a storage pool on my Harddisks.

But thats the wrong way to to it.

Your have install the operating system on the ssd.
Then you have to create a storage pool and a volume on the ssd.
Then you should create the storage pool on the harddisk.

The software will install automatically on storage pool 1 but you can change it in software center to install it on pool 2.

So I created the storage pools in the right direction and now everything is working. Apps are being installed on storage pool 1 the ssd.

I hope this information will help other people
Thanke you very much
