Hard drive replacement
« on: September 10, 2013, 04:41:48 AM »
Hi all

I have my 320L formatted as RAID, and was wondering if there is a way to upgrade one of the hard drive for a larger one, to increase overall capacity, but without loosing the data

To be honest - I don't think that this works.

I assume you have RAID 0, so both disks form a large Volume.
RAID 0 spreads data over both disks. If you remove 1 disk, all data is lost. Once you replace 1 disk, all data is lost.

In case of RAID 1, you may swap a disk, which will be rebuild (crossing fingers...). But you don't get more space for your volume. RAID 1 mirrors both disks, so the smaller one limits the size.

In all cases, I can strongly recommend to make a backup beforehand. It is very likely that after swapping 1 disk, all data is gone. Plan about 2 days for backup and restore...
