[ubuntu] Wrong size in RAID-5 array

view full story

http://ubuntuforums.org – So this is the first time I'm using RAID and I started with a 2x2TB RAID-5 array since I only had two disks at the time. Yesterday I got my third 2TB disk and was going to expand my RAID array to a 3x2TB RAID-5. So I used the following commands to expand my array and then let it resync. Code: sudo mdadm --add /dev/md0 /dev/sdd1 sudo mdadm --grow /dev/md0 --raid-devices=3 But after the resync I still only have 2TB available in my RAID array, ideas anyone? Code: fahrbot@Zoidberg:~$ sudo mdadm --detail /dev/md0 /dev/md0:         Version : 1.2   Creation Time (Hardware)
