Disk Space Expansion

I have 3 basic Volumes on a Windows Server 2003 file server. I have 2 SAS attached HP MSA70 devices. The second device has room to add 10 of 146GB drives. Can this space be given to one of the volumes or do I have to convert to dynamic?

You could add space and create new volumes, but if you want to increase an existing volume size, it must be dynamic (if you only use the integrated Windows Disk Manager).

Do not forget to backup, messing with disk and volume size is never risk free !

If you can add space to an existing RAID group and logical disk, you can expand a basic volume. It depends on how your disks and partitions are structured. I stay away from dynamic disks at all costs. Better to migrate a volume over to a larger basic disk than to span a volume over dynamic disks.

Agreed, you certainly don't need dynamic disks, online capacity expansion will create contiguous space so diskpart.exe can extend the basic disks. You may run into a problem though, adding 1.46TB to your current logical disk may cross the 2TB boundary and for that you would have to convert to GPT partition and you can't do that without backup/restore.

Would be easier to answer your question if you provide us screen shot of your server Windows Disk management snap-in.

I have included the Disk Management setup. I am trying to extend the F Volume. This is a SAS MSA70 setup with 2 enclusures. I planned on using Diskpart. I agree that I wil have a 2TB limitation problem.

As soon as you upgrade the configuration to drives bigger than 2TB sure you will have problems. But with GPT partitioning style you can easily overcome these problems. Is it 64bit system or x86?

andyalderSaggar makers bottom knockerCommented:
Doesn't really mater whether it's 3 or 64 bit, both support GPT but since you have to blow away the data to convert it's not worth expanding the array as it's wuicker to start from scratch (unless there are other logical disks on it which in this case there may well be as two disks just below 2TB size.

Actually there are tools already that convert the drive into GPT without dataloss. I used one yesterday for this.

Sounds great noxcho! i was beating my brain thinking I would have to delete the data and create a larger volume. What is the link?

I recently downloaded Paragon Hard Disk Manager 11 Professional and did convert the disk from MBR to GPT and was surprised to see that my data was intact. Then converted it back to MBR again with HDM and again to GPT. It worked like a charm.
You are working with server and you cannot use Pro version on it. You need Server version: http://www.paragon-software.com/business/hdm-server/
Also, check if trial version does the trick for you. I got the tool for free as I am expert at EE (Andy, you can get it as well).

After converting HDD into GPT - yes. The software do resize partitions on GPT disk. Just checked it.
