From Bug 6632 and 6630 a suggested sequence for Upgrading a Hard Drive size is detailed below after issue when attempting to sync a new drive when added first as sda
====Upgrading the Hard Drive Size after HD fail====
Note: these instructions are applicable if you have a faulty HD on a RAID system with more than one drive and intend to upgrade the sizes as well as replacing the failed HD. They are not applicable to a single-drive RAID 1 system, and increasing the useable space on such a system by cloning the existing single drive to a larger drive is not supported. See http://bugs.contribs.org/show_bug.cgi?id=5311
* CAUTION MAKE A FULL BACKUP!
* Ensure you have e-smith-base-4.16.0-33 or newer installed. [or Update to at least 7.1.3]
HD Scenario - Current 250gb drives, new larger 500gb drives
# Remove old 250gb HDD from sdb, leave old 250gb drive as sda on its own and boot up.
# Shutdown, connect one new 500gb drive as sdb and boot up
# Login to the admin panel and manage raid to add new (larger) drive to system.
# Wait for raid to fully sync
# Do full reboot with those 2 drives in place (1 original, 1 new)
#Shutdown again, disconnect the original drive, and connect the new drive just sync'd as sda (in place of original)
# Boot up again with just the one new drive in place, and confirm it boots OK.
#Shutdown, and connected the other 500gb drive as sdb
# Boot up login to admin panel and add sdb to the array, and wait for raid to fully sync.
# Reboot with both drives in place, and check RAID health is OK.
