RAID expanded/ incorrect volume size in OS

[PietM]

Good morning,
I inherited a setup as follows
Model name: TS-832PX
Firmware version and Build Number: QTS 5.0.1.2277 (2023/01/12)
Operation System (OS): Server 2012 R2
OS Language: English
Number of HDDs: 8
HDD model: Seagate
HDD capacity: 8TB
RAID configuration: RAID1

• Setup had 5 disks installed (bays 4-8)
  3 New identical drives installed bays 1-3
  Storage was expanded and shows correctly as 50TB
  Storage Pool 1, Volume 1 LUN 1 (Block-based Thick LUN)
  Connected to Server 2012 R2 iSCSI connector.

The issue is that in Disk Management it shows as 28TB volume with unused free space. If I try to expand this, it tries to convert it to Dynamic disks, which I would like to avoid. and not just expand.
I'm obviously missing something and assume it might be as simple as disconnecting the iSCSI connection and redoing it but not sure if that will break something else.

I have two of these units used for ArcServe backup, one needs to go back to the data centre,
Any pointers?

Thanks, Piet

Hard to tell without screen shots. Also I doubt it is raid 1.

Hi Don,

Indeed you are correct. It is RAID 5. Have no idea why I said RAID1. Attached screenshots of the QNAP setup and Disk Management.

Just some additional info.

You have to grow your block storage device filesystem..but that is not a QNAP issue

Check for Windows Guides (if Windows tools cannot help, you might need 3rd party ones)

Thanks Dolbyman,

My assumption was that I would need to change it from the Server side. This brings me to the next part. Since I can still access the data via the mapped drive on the server I assume that the QNAP RAID expansion process worked as it should.
Next question would be that if I redo the iSCSI connection, make the server forget the connection and reconnect, what is the risk of loosing the data on the QNAP storage? I'm not familiar with the iSCSI setup so will need to do some digging.

The block storage will stay the block storage ... reconnecting this will have no effect, you need to grow your virtual disk volume.

But as always, nothing will replace backups of your storage, backup your ISCSI contents (not from the NAS but from a client, in the case of ISCSI) regularly

see if this works

Good morning,

After some digging found that the original setup on the QNAP had cluster size set at 8192. This would limit the total to 32TB.
Process as follow.. create a new volume in the expanded storage. Copy the 16TB of data to the new volume. This is all on the same QNAP.
Once data is relocated, I will format the original partition with 16k clusters. Move the data back and then expand.

Will have to do the same on the other QNAP.

I have yet to find a way, if possible to use a tool like File Station to connect to the LUN and do the transfer there instead of the Server.
