NAS migration

[Enquiries]

I recently replaced my 4x4TB HDD by 4x8TB HDDs on my TS-453B RAID5. After thatd, I realized I originally created my system volume as a "4k bytes per inode", which limits max storage to 16TB and, therefore, prevents the RAID from being increased up to the available 21TB (Trully disappointed and angry at myself)
At this point I have the new 4x8TB HDDs limitted to my former capacity (10TB) with no option to revert them back to the 4x4TB.
I would like to hear your advise on what approach to take to leverage my new 4x8TB HDD. At this point, I am considering to buy a new NAS (TS 664) to migrate to. Yet, that would pose to re-create all my services (Plex, 12 x dockers, QVR Pro,...).
Can you suggest any better approach which could minimize all this admin work?
In an ideal world I would like to just migrate the HDDs to the new NAS but that would not solve the volume storage limitation.
Many thanks in advance

I understand your frustration with the storage limitation on your TS-453B RAID5. If you want to maximize your storage capacity without having to buy a new NAS and recreate all your services, there are a few possible options:

Backup your data and create a new RAID volume with a larger inode size: Since you cannot change the inode size on your current RAID volume, you could create a new RAID volume with the larger inode size and copy your data over. This would require backing up all your data first and setting up all your services again.

Use an expansion unit: If your current NAS supports expansion units, you could purchase one and connect it to your NAS to expand your storage capacity without having to replace your current NAS. This would require adding the expansion unit, setting up the RAID configuration, and copying your data over.

Use external storage: You could use external storage, such as a USB or eSATA drive, to expand your storage capacity. This would require configuring your NAS to recognize the external storage and moving your data to it.

It's important to note that expanding your storage capacity in any of these ways will require some amount of administrative work and configuration changes. However, they may be less time-consuming than buying a new NAS and setting up all your services again.
