Uprgrading Storage of RAID 5 4-disk

high_impact · Mar 14, 2015

In order to replace disks with more storage, could I simply swap one disk, wait for the RAID to rebuild on the new disk, and then duplicate the process for the other 3 disks? Would I then have non-allocated space available for use?

You would have non-allocated space. You could create another volume, but probably couldn't expand your existing volume.

A lot would depend on your RAID controller. But, I know that in many cases after upgrading all the drives it's just a matter of adjusting the partition table to take advantage of the extra space.

To grow an existing RAID volume. the RAID engine MUST support ONLINE expansion.
Check you RAID engine feature 1st. Most Mobo's raid engine wont offer such feature. Only enterprise RADI card offer ONLINE expansion.

But that is not an impossible task. You can create a 2nd volume on the non-allocation space, then append this volume to the existing one.
Now you have a ONE virtual volume
Remember to back up your data

there is always a risk of loosing your data
