Hi all,
I try to defrag my btrfs root partition (run by root privilege)
find / -type f -o -type d -print0 | xargs --null --no-run-if-empty btrfs
filesystem defragment -t $((32*1024*1024))
1. This kind of error messages is
If there is a lot of small files, then the size of metadata will be
undesirable due to deduplication
Yes, that is a fact, but if that really matters depends on the use-case
(e.g., the small files to large files ratio, ...). But as btrfs is designed
explicitly as a general purpose file

Hi everybody,
I need some help understanding the nodatacow behavior.
I have set up a large file (5GiB), which has very few EXTENT_DATAs
(all are real, not bytenr=0). The file has NODATASUM and NODATACOW
flags
I don't publish the patched because aren't in a good shape. However I
really like the output. The example is a filesystem based on three
disks of 3GB.
It is clear that:
- - RAID0 uses all the disks
- - RAID1 uses two different disks
Comments are welcome.
Known bugs:

Howdy,
I can wait a day or maybe 2 before I have to wipe and restore from backup.
Please let me know if you have a patch against 3.6.3 you'd like me to try
to mount/recover this filesystem, or whether you'd like me to try

My suggestion is that by default a summary similar to the existing df command

1. I also added mount option 'compression=lzo' and 'io_cache' to /home at
first.
Neither io_cache nor compression=lzo are options that exist. You
probably meant compress=lzo for the first, but I really don't know
what you wanted for io_cache (inode_cache? that's not really a
performance
