Have a old Ultra2 (but new), had only 1 disc with 2 TB from the beginning, now i put in a new disc with 4 TB. I can see it in the Raider but i don´t get any moore space on
the network.
Tryed many things but proebly not the right thing.
Assuming you are using the default xraid: If you added a 4 TB drive to your existing 2 TB drive, then there will be no space increase.
The ultra normally creates a raid-1 volume (with protection against single-drive failure). Space is limited by the 2 TB volume already installed.
The simplest path is to get another 4 TB drive, and replace the 2 TB drive also. Then you'll end up with 4 TB of protected data.
Your other option is:
(a) back up your 2 TB of data somewhere
(b) do a factory reset with 1 drive in place. Choose "flexraid" from Raidar (the 4.3.8 version, I don't think the 6.0 version will work for this). Set it up as RAID-0 with only the one drive installed.
(c) Add the second drive, and select RAID-0 for that one also.
(d) create the shares you want (some on the "C" volume and some on the "D" volume). Recreate any users, etc.
(e) restore data to those shares form backup.
This is painful (however with 4.2.x firmware you would have needed the factory reset no matter what). Although flexraid will let you create a single 6 TB volume, that is usually a bad idea. If either drive were to fail, you'd lose all data from both drives. The instructions above prevent that from happening.
It seems that your NAS is set on X-RAID that is why the 2TB part of the new 4TB disk has been used for mirroring and the other 2TB part is unused. If you want to maximize the space, kindly backup first all of the data from your NAS. Then, perform a factory reset on your NAS with both the 2TB and new 4TB disks inside it. On the initial setup, select Flex-RAID and choose RAID-0 so that you could maximize the space. But be reminded that if one drive fails, all of your data will be all wiped out since its set to RAID-0. It is advisable to have a backup of your data to an external drive or to another NAS.
