kernel: 3.9.0
btrfs-progs: pulled from git this morning
Trying to receive a 5gig send file. the first bit is fast, doing 10 - 50MB/sec.
then it slows down. cpu usage is 50% (dual core machine).
when i do a strace, it looks like this, repeating over an over, about 1 piece
each second:

Hi list,
I am using kernel 3.9.0, btrfs-progs 0.20-rc1-253-g7854c8b.
I have a three disk array of level single:
# btrfs fi sh
Label: none uuid:
I wrote a little tool you can use to scan a file and punch holes, so make it
sparse.
Confirmed to work on 3.7.0-rc6
Feel free to use it in any way you like, and of course improve it.

issue:
on my system i have 2 entries for /, one with the type ‘rootfs’ and a 2nd one
with the type ‘btrfs’. find_mount_root() uses the first one and reports a fail.
My change:
if (longest_matchlen len) {
into:
if (longest_matchlen = len) {
i have not tested this, but in my understanding it
I think thats possible with btrfs-send/receive

I am new at this btrfs stuff!
As I understand it, you can add a physical disk or partition and have data
spread into the new space. You can also move data off a disk or
Can't thus be done with a regular file and a loop back device?

Yes, zvol like feature where a btrfs subvolume like construct can be
made available as a LUN/block device. This device can then be used by
any application that
would be really cool if a TRIM to the loopback device would do a 'hole punch'
on the file

Thanks for the sparse file idea, I am actually using that solution
already. I am not sure if its the best way, however.

first, i did the following: `btrfs val start -dconvert=raid5,usage=1` to
convert the mostly empty chunks.
This resulted in a lot of allocated space (10's of gigs), with only a few 100

FIrst, a bit of history of the filesystem:
used to be 6 disks, now 5. partially raid1 / raid10. been migrating back and
forth a few times.
As some point, a balance would not complete and would end with 164 ENOSPC’ses,
while there was plenty of unallocated space on each disk.
i scanned for
to provide useful information?
