Buffalo Forums

I am considering populating 4 of the 8 drives in my TS5810.

I have 4x8TB in bays 1-4 in a raid 5 array1 config.

I want to install new larger drives alongside the above in bays 5-8.

Can I install 16TB disks into bays 5-8 and then create an array2.

Buffalo don't mention anything about the maximum drive size the units OS will recognise, they only state 64TB limit as that's the most space you get with the bays populated with 8TB disks, which is how they ship it.

So it seems folks are left to try and see if the unit accepts larger disks and creates an array. Has anyone tried this and managed to get the unit to recognise  a bigger array size? And therefore exceed the 64TB total that Buffalo advertise it as

hmm, I have a TS3410 but it sounds like I'd need a TS5810 or larger and a pile of 16TB drives to test it....sadly I don't, though I do accept donations.

I'm overdue to look into this again, but going off my notes from a few years ago....

I believe this generation of device uses a 32-bit ARMv7 architecture, but one that uses 32K memory pages instead of the usual 4K memory pages (which required some interesting kernel and library customization). I would expect this to mean that the the normal 32-bit kernel limitation of 16TiB volumes would be extended to 128TiB for these devices. As far as I know the other tools involved (mdadm, xfs, etc) are built to run on systems with a variety of architectures and page sizes and should be able to handle whatever the kernel supports....as far as I know.

I would guess 128TB would be the volume limit, but absent the relevant hardware to test with it's only a guess.

Thanks for your reply, sounds promising enough to try using some larger drivers, say 16TBx4 to see.

Incidently, I have a TS5400D model, which was shipped with 4x1TB disks, and I upgraded them to 4x8TB, this works fine on the latest firmware for the unit.
