Hi,
I asked in other linux forums and did not get enough info. So I come
here even though this is not mdadm/RAID issue.
I replaced 3TB disks in my 6-disk RAID6 with 6TB and now my md0 is 24TB.
I had 32bit version of ext4 on it which can only be grown to 16TB. Any
one had this issue before and any _/inplace/_ good solution to grow ext4
to full 24TB? It is unlikely that I will be able to back up and recreate
file system.
My filesystem is on md0 drive so I guess partitioning and making into 2x
12TB ext4 will not work. I am not even sure if we can partition md like
any other disk.
On the web, I only found one solution that required upgrading kernel to
some very recent one (not in my distro) and getting the bleeding edge
resize2fs. This makes me nervous. Is there a solution that avoids this.
