Subject: Is there a way to flag specific directories "nodatacow"?
Date: Sun, 02 Jun 2013 07:40:52 -0700	[thread overview]
Message-ID: <51AB5974.3080803@chinilu.com> (raw)

I am seeing massive journal corruptions that seem to be unique to btrfs 
and I am suspecting that cow might be causing them.  My bandaid fix for 
this will be to mark the /var filesystem "nodatacow" at boot.  But I am 
wondering if their is any way to flag a particular directory as 
"nodatacow" outside of the mount process.  I would like to be able to 
mark /var/log/journal as "nodatacow" for example, without having to 
declare it a subvolume and mount it separately.
