Why migrating from RAID 1 to RAID 5 did not expand the storage capacity on ZyXEL Communications NAS542?
If migrating from RAID 1 to RAID 5 did not expand the storage capacity on your ZyXEL Communications Storage, it may be because the NAS rebooted during the RAID re-build. After the re-build finishes, go to the Storage Manager screens, select the volume or disk group, click 'Manage', and use the 'Expand the volume with unallocated disk space' option.
Why replacing smaller disks in a RAID 1, RAID 5, or RAID 6 with larger capacity hard disks did not expand the storage capacity of ZyXEL Communications Storage?
If replacing smaller disks with larger ones did not expand the storage capacity of your ZyXEL Communications Storage, it could be because the NAS rebooted during the RAID re-build. After the re-build finishes, go to the Storage Manager screens, select the volume or disk group, click 'Manage', and use 'Expand the volume with unallocated disk space'.
