How to grow a RAID5

Hi,

 

Not sure I should ask this kind of question here, but here it goes:

 

THe question is how to grow a RAID5 after replacing 4x2TB with 4x4TB


I replaced each disk one by one and hit recover each time a disk was replaced. I have access to all the files. After that I used the command "mdadm --grow /dev/md127 --size=max" to grow the size. I'ts now showing 10.92TiB in Raid Management but it didn't reshape or grew the partitions/filesystems. If I hit resize in File Systems for one partition, nothing happens.

I have two partitions:
/dev/dm-0
/dev/dm-1

ignore /dev/sde1, it's an external usb HDD.


Any advice? how can I resize the partition without loosing data?
 

Thank you.
