Subject: question about ext4 backup block group descriptors
Date: Thu, 31 Jan 2019 16:07:04 +0800 [thread overview]
Message-ID: <4fc3271a-3098-afcd-24c1-e2e130e1e86a@linux.alibaba.com> (raw)
hi,
Anyone can help answer when ext4's backup block group descriptors are updated?
I had used blktrace to track the corresponding backup block group descriptor
block, but didn't find that any backup blocks were written.
Thanks in advance.
Regards,
Xiaoguang Wang
