RAID 1 and Drive Removal

Postby Reino » Dec 18th, '13, 10:42

On the G-Drive ev Thunderbolt, once formatted to RAID 1, can a drive be removed to become portable (for example to gather data somewhere else from a non-thunderbolt device) and then be put back in the unit and have the RAID 1 be automatically re-built or will it become a broken RAID 1 that cannot be re-built to its former RAID 1 state? If it does re-build with the new data, does this take a reasonable amount of time or is the re-build a much slower than a typical data transfer process?
Thanks!

Hi Reino,

Thanks for posting. In a raid 1 configuration if you take one if the drives to use independently it will require a rebuild once it is repaired with the other drive. This will take quite a bit of time as the rebuild goes sector by sector. Keep in mind the top drive is regarded as the master so if new data is on the second drive when reinserted the old data of the top drive will overwrite the any new data on the bottom drive.

So, just to confirm my understanding: In a RAID 1 configuration, if one of the drives goes bad and needs to be replaced, the good drive will need to be moved (if necessary) to the top slot, and a new drive added on bottom. All data will then get copied to the new bottom drive automatically. Dustin, please confirm. Thanks!

Hi Reino,

Correct. If the raid data is still in tacked the top drive will rebuild to the bottom drive, never the other way.

If I swap out a RAID 1 Drive with a Drive from another RAID 1 set, in the Orange LED mode, does that cripple drive performance via Thunderbolt?

Hi Bay,

Thanks for posting. Swapping from another raid 1 set will not decrease performance but you may need to initialize the rebuild manually if you want to use that drive as the replacement.
