So I have to move 15TB of data off my existing server to the new unRAID box.  I have seen a few threads where people moved a few TB across their network, but 15TB across a network will really take an unbelievably long time.

 

What I would like to do is use a 4TB internal SATA drive.  I need a file system that supports both Nas4Free and unRAID.  It can be a file system that N4F can write to and that unRAID can only read, but I am not sure what that file system may be (if it exists).  I know that both N4F and unRAID support reading ext2 and NTFS, but N4F does not support writing to either of those file systems.

 

Does anyone know if there is a file system that can work for what I want to do?  I could also consider using a 2TB hard drive to do the transfers if there is a file system that will work that can't support larger partitions.

 

Can unRAID read from UFS formatted disks?  Because that may work, but I have not seen anything stating that unRAID supports reading UFS.

 

Thanks,

Assuming you want UnRAID to maintain fault tolerance on everything you write to it, the write speed on the array is going to be well below what a Gb network can provide ... so there's NO penalty to just copying it across the network.

 

Even if you write the data before you add a parity drive, a Gb network comes very close to the sustainable write speed of modern drives (except on the outer cylinders) ... so there's little penalty.

 

In short ... just build the array; then copy the data across your network.  Yes, it'll take a good while for 15TB (close to a week) ... but it just takes a couple minutes of your time to start the copy.
