Hello mdadm Linux-RAID experts;
My Goal: Expand (grow) my array from 6xHDD (RAID6) to 8xHDD (RAID6)
This is my root cause problem: when I went to try to add the new drive
(already formatted for Linux RAID partition):
fermulator@fermmy-server:~$ sudo mdadm --add /dev/md2000 /dev/sdq1
mdadm: /dev/sdq1 not large enough to join array
As I have researched and learned, I need to:
A) shrink the filesystem (ext4) -- done (shrunk by a generous 1.6GB)
B) shrink the array size -- incomplete (unable to proceed, the --grow
command doesn't do anything)
I've been following this guide:
http://webapp5.rrz.uni-hamburg.de/SuSe-Dokumentation/manual/sles-manuals_en/manual/raidresize.html#resizedecrraid
This pastebin shows my array details, the 'existing' drives (fdisk) and
'new' drives (fdisk) - http://pastebin.com/U04VJpE4
Any ideas?
~Matt
