I'm running 4 500GB WD drives in a Raid 1+0 configuration. I running low on space and was hoping to upgrade these drives to 1 TB each. Is there any way to go about this without copying to backup and restoring from that backup to the new drives? Thanks!
OK, I'm not 100% on the capacity of your setup, but I'm assuming it's 1TB... Backup to one of the 1TB drives (make another copy on another 1TB drive just in case), then wipe your raid and backup the 1TB drive to two of the 500GB drives (make a copy of that as well on your other 2 500GB drives). After that, you can wipe the 1TB drives, build the raid with them and copy the data from the 2 500GB drives back to the raid. That's assuming your current setup has < 1TB of data.
