[WIN7] Expanding a partition in win7

Anyone?

Can you post a screen of disk manager showing the partition(s) on the drive.

I'll get the screenshot when I get home.

Usually the problem is you have something to the right of the partition you are trying to expand. There can be nothing there. It must be unallocated space.

Sorry what is LUN? Never seen that before.

You will more then likely need an Aftermarket Disk partitioning program.

So the array is strictly for storage purposes and you are trying to mount the 4 TB as one logical volume?

What type of disk volume (GPT or MBR) is the OS installed in on the machine running the iSCSI client? Who/what is providing the iSCSI target function at the array?

The array (IE the target is a QNAP TS-469-Pro)

the C drive of my computer is MBR (as you can only have a GPT boot drive if you have a UEFI boot system)

the Volume that shows up in disk manager is formatted as GPT NTFS (as mentioned in the OP.)

The computer sees the 4TB volume but can't expand the 2TB partition on it to fill the volume. (I can make a partition on the 2nd 2TB but it won't let me make the 1st partition fill the volume)

iSCSI Client windows 7 Pro x64
iSCSI Target QNAP TS-469-Pro

Well, from everything I've been able to find out, I'm thinking you're going to have to re-create the GPT on the newly expanded 4 TB volume in order to include the added space. This should then allow the entire 4 TB to be seen in disk management, where you can then do whatever you want with it.

Well Disk management sees the full 4TB and will put a 2nd partition on it but not expand the existing one to fill it.

Ok, if your content to use it with the additional volume, that's good.
Just one more question, on the original NTFS disk on that volume, what sector size was used?

reply to DarkLogix
On the upside if I have to redo the Partition then luckily it's thin provisioned so I can make another 4TB lun and have my server work away at moving the data over. (I say server because it'll take awhile and I don't feel like leaving my computer on, but my server is always on)

Though I'll consider moving forward with connecting the 2nd Nic sooner. (the server has 2 nic's teamed and the qnap has 2 nics but I haven't connected the 2nd on the qnap yet.)

well, so far everything I have been able to find out ties back to a limit of the NTFS format and 512 sector size being a max of 2 TB. Unfortunately I'm in no position to verify this in practice. If you were able to remove the current NTFS partition such that you had the entire 4 TB raw volume and then create a new NTFS partition using 4096 sector size, you should be able to use it all.

Could you refresh my memory, is there a command to show sector size?

and is it possible to adjust it?

Ok from some refreshing I guess I'll make another iSCSI lun and target on the QNAP and (with thin provisioning I can have 2x 4TB luns on a 4TB array so long as the total amount of actual data stored isn't more than 4TB)

And let my server spend the night moving files from one lun to the other.

I wanted to be sure that it was the issue before doing that though
