Okay so i have a 2220 controller from highpoint and i am using vista 32bit OS and i cannot get my array to expand over 2TB. i have dont Online expansion before with out issues but the new space will not show up in drive management.


is this an issue with vista 32bit?

any ideas would be great
 
I presume you aren't using GPT? If you don't use GPT and have 512b blocks (default), you're also stuck at 2TB. You pretty much have to recreate the array to fix this. Either use GPT (easier solution) or 4k blocks (RAID card might not support it) when you recreate the array.
 
i thought i had used GPT, how can i check......

i can offload the data and recreate the array. PITA, probably wait until a later date to due so.


I guess i need to know how i can check to see if my volumes are GPT
 
As promised here is what it looks like in windows7 (and probably vista):

On the right you have to More actions and for the top (or bottom part) change the view type from "Volume List" to "Disk List" then it will show the partition type under "Partition Style"
 
You can also use the command line and use "Diskpart" to view the information, delete and remove volumes, etc.
 
okay well it is GPT and i tried to use diskpart to extend the volume and it says that there is not enough free space to extend the volume, even though in the highpoint manager it show a 3tb volume...

hmm, ill get this eventually :)


i am not sure what is going on. In the highpoint software it shows 3TB of space but in windows it only shows 2TB and it does not see the free space.


How do i get windows to see the newly added space?
 
the disk manager should show the drives size as 3TB with a 2 TB partition. if it doesn't then something is wrong. Have you rebooted since the OCE finished? If you haven't that might be why you can't see the extra space yet.

I just thought I would add (no idea of this is the case or not) but vista32 may not support lba64 which means even if it supports GPT it can't see block devices over 2TB. I know this is the case for windows XP-32 (although it doesn't support GPT either).
 
yeah i have restarted, stiill shows up as 2gb in disk management but in highpoint manager it is a 3tb array...


i will install 64 bit on another partition and see if that fixes the issue..


if i have 2 partitions and 1 sees 3tb and the other only sees 2tb and i put data on the extra 1tb will that data just not be there in the 32bit partition..


thanks for the help, ill post back when i get the chance to install 64bit
 
I have a 3ware 9650SE. Connected 6x1.5TB drives in RAID 6. The array is showing at 5.45TB in BIOS and in ubuntu or gparted live but Windows Server 2008 64-bit refuses to see more than 2TB even when converted to GPT. I am clueless as to what I am doing wrong since it should support more than 2TB.

Any ideas are appreciated.

This is my first post here BTW so take it easy on me if I am missing something obvious.

Thanks.
