Subject: [QUESTION] Why overlayfs cannot mounted as nfs_export and metacopy?
Date: Sat, 7 Aug 2021 18:17:02 +0800	[thread overview]
Message-ID: <ec78de1b-4edb-1eea-5c0d-79e65f139d79@huawei.com> (raw)

Hi, all.

As title said. I wonder to know the reason for overlayfs mount failure 
with '-o nfs_export=on,metacopy=on'.

I modified kernel to enable these two options 'on',  it looks like that 
overlayfs can still work fine under nfs_v4.

Besides, I can get no more information about the reason from source 
code, maybe I missed something.
