Hi,

2 years ago i built my own 'NAS' system running Windows Server 2008 R2 so i could use the software Raid 5 it provides. (This was to save on cost of hardware raid card). It has 8 2TB drives with a raid 5 volume using all their capacity. On top of this, Truecrypt is encrypting the entire thing as a non system partition. As you can imagine, the performance is pretty crap so I want to move away from this.

But the way I see it I am stuck. Truecrypt does not allow 'in place' decryption of non system volumes. So it cant be decrypted without saving ALL the data somewhere else. I do not have any other capacity to store the data anywhere else. Even moving a bit at a time would not work since the whole lot has to be backed up so the volume can be deleted and I can start afresh?

Truecrypt does not seem to allow shrinking of the volume either. So i don't think I can move stuff off bit by bit and keep shrinking the entire thing.

So please does anyone have any ideas or solutions (hopefully i am wrong) on how this can be achieved without having to purchase storage space equivalent to whats on the drives.

Thanks for reading

That's really unfortunate.

I don't think there's anything you can do at this point except gradually migrate the data. You're already at a big risk of losing it so the best you can do is hope that you don't suffer data loss until you can afford the storage to backup.

Adding to the problem I just saw apparently you cannot shrink a Server 2008 raid 5 volume without recreating it. So am I screwed? Hopefully one of you guys has some clever ideas. I just want the files in a normal state on NTFS partitions so it can potentially be moved to a Win 8 storage pool or something. Cheers

You had a 16TB RAID5 with Encryption and you weren't backing it up?
Honestly you're lucky it hasn't failed leaving you without your data.
Having to buy 16TB of storage to transfer it to should be the least of your concerns.
