I would like to avoid running out of space. is there a way to know that
I am getting close? i'd like to make a script that runs as part of my
bash prompt and lets me know when i am getting close. i know there are
several ways
I'll reboot the thread with a recap and my latest findings.
* Half full 3TB disk converted from ext4 to Btrfs, after first
verifying it with fsck.
* Undo subvolume deleted after being happy with the conversion.
* Recursive defrag.
* Full balance, that ended with 98 enospc errors during balance.

When function btrfs_statfs() calculate the tatol size of fs, it is calculating
the total size of disks and then dividing it by a factor. But in some usecase,
the result is not good to user.
Example:
# mkfs.btrfs -f /dev/vdf1 /dev/vdf2 -d raid1
# mount /dev/vdf1 /mnt
# dd
We just need the type of a chunk to calculate the number of parity stripes,
but we have to pass a structure of lookup_map to it. This will prevent some
callers to use it where there is no a convenient lookup_map to be passed.
This patch replace the parameter of struct map_lookup * with a profile
When we use btrfs with raid5/6, the output of df is unexpected as below.
Example:
# mkfs.btrfs -f /dev/vdf1 /dev/vdf2 -d raid5
# mount /dev/vdf1 /mnt
# dd if=/dev/zero of=/mnt/zero bs=1M count=1000
# df -h /mnt

David,
I was wondering if you could please send out announcements for btrfs-progs
when you tag a release or -rc? There doesn't seem to be a good mechanism
to track releases and IMHO the more people are notified, the more
testing we can get, not to mention faster propagation into distros.
Sorry to come up with an old thread, but I'm really interested if
something is going on with that idea. It would help in many situations
if you could promote snapshots to regular subvolumes.
Let's for example take btrfs-restore: It does not restore snapshots by
default, which is rather smart,
