Replace broken HDDs - increase capacity

I have a Pegasus2 R6 that was initially equipped with 6x2TB HDD. Now, after quite a few years, one HDD broke down and needed to be replaced. Since there is almost no more 2TB HDD on the market and I can get higher capacity for the same price, I have opted to buy a 6TB HDD as a replacement.

Unfortunately, another old 2TB HDD died quickly after that, which I also replaced with a 6TB HDD.

 

So now I have 4x2TB HDD and 2x6TB HDD resulting in a disk array with 'configurable capacity' of 12TB and total physical capacity of 20TB.

As for the LD (RAID5) there is a 'capacity' of 10TB and a 'physical capacity' of 12TB, thus unchanged.

 

Now the obvious question: How can I use the extra capacity as provided by the new hard drives with 8TB extra as compared to before?

Is it even possible (using RAID5) to increase the capacity of the logical drive, if there is still a 2TB HDD in the system?

Hi Hans,

Unfortunately, you cannot use the unused storage in this configuration.

Is it even possible (using RAID5) to increase the capacity of the logical drive, if there is still a 2TB HDD in the system?

If all the disks were now 6TB there is a rather complicated process where all the unused disk space could be added to your Volume.

Use this process at your own risk.

Hi R P,

While this is not the answer I was hoping for, I do greatly appreciate your swift response, which is straight to the point.
