Subject: How can I do online resize from 14TB to 30TB?

I saw the mail "E2fsprogs master branch now has all 64-bit patch applied" written by Ted.  Ext4 with 64bit couldn't do online resize which is larger than 16TB, because "meta_bg" in kernel is not ready.

However, it really took lots of time to do off-line resizing.  Could I do online resize without meta_bg?  Or what can I do for e2fsprogs to support online resize for larger than 16TB?

Best regards,
Chien-kuan.
