[Users] OVZ6 kernel panic on Debian 9

[Narcis Garcia]

I've debugged initrd steps, and localized an error in this action:
$ mount -r -t ext4  /dev/sda1 /root
EXT4-fs (sda1): error loading journal
mount: Invalid argument

If I try there same command without readonly option:
$ mount -t ext4  /dev/sda1 /root
EXT4-fs (sda1): couldn't mount RDWR because of unsupported optional
features (400)
mount: Invalid argument

I see that Debian 9 installer formats Ext4 with two extra features that
Debian 8 didn't:
64bit metadata_csum

Does anybody know how to "downgrade" Ext4 to remove those 2 features?
