Imagine I have rootvg design as below:
/dev/sda
|___ /dev/sda1
|___ /dev/sda2
|___ /dev/sda3 30G [part]
|___md1 30G [raid 1 ]
/dev/sdb
|___ sdb1
|___ sdb2
|___ sdb3 30G [part]
|___md1 30G [raid 1 ]
I’ve extended both disks from vmware side by 10GB each
/dev/sda ---> 40GB
/dev/sdb ---> 40GB
‘fdisk -l’ show new disk sizes -OK.
Can I grow size of partitions /dev/sda3 & /dev/sdb3 so that ‘mdadm –grow max’ can see unallocated space and extend my RAID1 to maximum?
Is this even possible to do it online? I don’t want to destory partition table and create bigger parts as this is my rootvg 🙂 Or maybe I need to double the size of current disks, create partitions with same size as my current ones and then grow via mdadm?
I am really stuck with this. Sorry for newbie question! Please help me with good advise!
