All,
When adding a subvolume to a qgroup, pre-existing files in that
subvolume are not counted in the referenced/exclusive space of the
qgroup. Is this intended behavior ?
I create a subvol with one file:
# mkfs.btrfs /dev/sdg
# mount /dev/sdg /mnt/fulldisk
# cd /mnt/fulldisk
# btrfs
All,
The "btrfs qgroup limit" command has an option -c which means "limit amount
of data after compression". Whether this option is specified or not, I seem
to be able to write more well-compressible data than the specified limit. I
was expecting that omitting the -c option would never allow me t
not yet implemented, while it should be
executed after enabling quota on a non-empty filesystem.

When data in a file is overwritten, starting somewhere in the middle of
the file, the overwritten space is counted twice against the space usage
numbers. Is this a bug, or did I something wrong?
This is what I did:
I create a subvolume and limit it to 4 MB, and create a 1000 KB file in

nds like a good

Commit 8d082fb727ac11930ea20bf1612e334ea7c2b697 (Btrfs: do not mount when
we have a sectorsize unequal to PAGE_SIZE) requires the sectorsize to be
equal to the pagesize for the filesystem to be mountable.
The nodesize and leafsize should be equal, and not larger than 65536.

When trying to create a clone (reflink) of a file on a different device,
you'll get this error:
Invalid cross-device link
However, an empty file is created on the target location. An invalid
clone operation should not result in the creation of a file.
Example:
# mount

- Reflink the reflinked file
- Modify the original file
