 Actually it is possible. Check out David's response to my question from

 this was a quick aid, please see attached file for an updated tool to set
 the file flags, now added 'z' for NOCOMPRESS flag, and supports chattr
 syntax plus all of the standard file flags.
 
 Setting and unsetting nocow is done like 'fileflags +C file' or -C for
 unseting. Without any + or - options it prints current state.

Hot data Tracking

2012-02-10 Thread Timo Witte 
What happened to the hot data tracking feature in btrfs? There are a lot
of old patches from aug 2010, but it looks like the feature has been
completly removed from the current version of btrfs. Is this feature
still on the roadmap?
