Just wondering what would be the fastest way to replace the 500 GB hard drives with 1.5 TB hard drives and copy the data over.  I'm guessing I could take the 500 GB drives out, read them in Windows 7 (it can read EXT2, right), and copy the data over to the 1.5 TB drives?

thanks!

that's what i would do.  although i would place 2TB drives instead (1.8 FW i believe allows this) so i would not have to replace the drives in a loooooong while.

Standard or RAID1 configuration?

Standard configuration - no raid

If you have two 1.5TB drives I would take on of the drives out and replace it with 1 of the 1.5TB drives power it back up and move the data from the remaining 500GB drive to the 1.5TB. Next Power it down and swap the 500GB drive with the other then power it up and do the same. Once done remove the 500GB and insert the second 1.5TB and format it.

I would like to do the same thing and have two 500GB drives in a RAID1 config and would like to move to either a pair of 1.5 or 2TB drives also in a RAID1 config. I think I am running fw1.07 (although I am not at home to check it).

I have space on the network to move the data if it makes sense but if there is someway to do one drive at a time that would be better for me.

1. I am looking for a methodology to accomplish this upgrade
2. Does the config remain in the device in NVRAM even if both drives are lost?

[Jamesy]

Thought I would bump this one, as I am looking to buy new drives this weekend and looking for a strategy to upgrade to the old 500GB drives. Thanks in advance.

The easiest way will be to backup the data, install new disks, create a new array and restore.  There is no simple way to swap one disk at a time and "grow" the array.

Thanks for the quick reply. Do you know if the config of the NAS would be preserved? Is the config stored on NVRAM in the unit (not on the RAID set) correct? Thanks again in advance.

Usernames, passwords, access, etc. is stored in flash memory and not on the disks - this may or may not be of significance if you "upgrade" the drives - since you will need to recreate the directory structure exactly the same way it was before for the permissions to work.

Can you clarify this for me? I have two 500GB drives in a RAID 1 configuration. Are you saying I should:
1. Power down
2. Remove one 500GB drive
3. Insert new 1.5TB drive
4. If it's a RAID 1, will it automatically mirror the contents? If this so, then:
5. Remove second 500GB drive
6. Insert second 1.5TB drive and the DNS-323 will sync with the first drive.

Is this correct? If not, what is the procedure for a RAID 1 configuration to replace the drive set with a larger one?

Thanks!

good question i would like to know as well

No it's not,that is for standard volumes (NO RAID) only - the procedure for RAID was provided in an earlier response.  There are other ways, this one is the easiest.

Just out of interest, what is it that stops this approach from working? I always assumed when I want to upgrade I'd insert the new disks one at a time and have the array restored automatically. If a disk goes bad you can just insert a fresh one and have the raid array restored, right? So is it the fact the disk is larger that stops this approach from working?

[fordem]

If you have a disk fail and you replace it with a larger disk, the system will create the exact size partition used in the original array on the new disk, and the remaining space will be unavailable until you reformat the disks or get creative with linux.

The same thing will happen if you swap the disks one by one and allow a rebuild - you will end up with a RAID array of the original size and have no access to the remaining space on the two disks.
