I've been reading the forums a bit and I've seen jfourman mention he was able to get 4x1.5TB working, but he didnt mention the model # of the TerraStation he was using. I'm ready to go for 4x2TB to get 8TB of raw space.
I've seen the step by steps but I'm interested in finding out if it will work before I buy the stack of hard drives. In the past I've upgraded from 1TB to 4TB by putting the 4x250 setup into RAID1, and swapping out drives 1 and 3, rebuilding, then drives 0 and 2, rebuilding, delete the array, then reinistiallize the full size array in my prefered configuration (RAID5).
Tech support is no help at all. they tell me that the TerraStation 2 series has a Kernal that can only support 4TB max, but they sell a 6TB TS2... They told me: "it has special chips and firmware, you cant do that yourself unless you are a linux guru"
I'm no linux guru, but i do know how to use a command prompt. I'm not too worried about voiding my warranty either (though I think that is a cheap way of keeping people from upgrading the boxes themselves). I'm mostly intersted in hearing if other people have been successful getting to 6 or 8TB, and what model and firmware they were using.
Here's my info:
TS-HTGL/R5 F/W 1.27 - upgraded it from 1 to 4TB

I happened to have a 2TB drive from Hitachi (HDS722020ALA330). I tested it just to check if the Pro II could detect it and
after formatting, it showed up nicley :) I'm not saying 4 of these drives will work, but it *seems* the TS-HTGL/R5 can
detect the drive with a correct size at least. (1.8TB formatted XFS) If there indeed is a 4TB limit to the kernel then it would
be no joy in the end though...

It will work, you will need to go drive by drive restructering the raid at each drive you swap out, than after you have done this for all four drives you will need to drop the entire raid, reformat, than re-assemble the raid to see the full amount

I have just tried this, I have a TS-RITGL /R5 iSCSI Rackmount TeraStation Pro II that was no longer being used, I have used the above swap method to exchange the 4x Samsung 500GB drives with 4x WD Caviar Green 2TB (WD20EARS-00MVWB0), dropped the Array and setup RAID 5 now sees 5,835,956,352 kbytes (5565.60 GB) just need to wait the 36 hours for it to check the array.
If this works I also have a TS-HTGL/R5 F/W 1.33 TeraStation Pro II to play with this one goes into TFTP EM mode but have been unable to connect to it as yet.

I have successfully upgraded my TS-H4.0TGL R5 with updated firmaware 1.35, to 8 TB by replacing each 1TB drive with 2 TB drive. I replaced each one individualy and rebuilt the array before replacing next drive. I now have 8TB operating successfully. I would suspect 3TB drive would work too.

I have a LS-QVL2 that I want to replace the 4- 500gb drives with 2tb drives. I replaced one drive at a time and drive 3&4 showed as 2tb, 1&2 still showed as 500gb. I reformated drives 1&2 , deleted the array. When I created a new array the array still showed 2tb total. What did I do wrong?
