So, I have a feeling this is a ridiculously easy question to answer, but I'd like to verify prior to potentially ruining a ton of data.
Currently, I have a 18TB RAID5 array (7x 3TB disks) and I'm trying to add another one. Now, I'm aware that there's a way to do it command line via mdadm without losing data, BUT, what I'm trying to figure out is if I can use the Disk Utility to expand the array without wiping out the data. In particular, I'm selecting the raid array, and then clicking 'Edit Components' and then 'Expand Array' and adding a disk to the array.
Please, in no uncertain terms: If I add a disk to the array in this manner (via the Disk Utility), will it erase my data?
Thanks in advance.
