This may sound like a dumb obvious question with an appropriately dumb answer but I want to be sure I don’t loose data: I have a drobo S configured as :
2 x 1.5TB disks
3 x 500GB disks
I want to replace the 3 x 500GB drives with two new 2 x 1.5TB drives to create a 4 x 1.5TB array.
I was thinking of removing the first 500GB drive, waiting for the drobo to update then removing the next 500GB one and waiting for it to sync and finally removing the last 500GB drive and waiting for that to sync before then adding the two new 1.5TB drives.
Will this work or what do I need to do to achieve my goal?
