Here is a stack trace I got when removing a device from a raid1 filesystem.
I have run a check on the filesystem and I got no errors, just a message about
the free space tree needing to be rebuilt, which I did on mount.

Hi All,
I was rsyncing some subvolumes last night and at some point it stalled.
Stacktrace is provided in case it is helpful to devs.

Hi all,
I was running dedupe on my filesystem and something went wrong overnight, by
the time I noticed the fs was readonly.
When trying to check it this is what I get:

Just ran into this warning while running deduplication. There were 10's of
thousands of them over a 24hr period. No other problems were reported.

Hi
I have a system that crashed during a defrag, upon reboot I got the following
trace while resuming the defrag.
Filesystem is BTRFS Raid1 on lvm+cache, kernel 4.13.2
Check --repair gives lots of warnings about parent transid verify failed, but
otherwise completes without issue.

While reading the thread about adding zstd compression, it occurred to me that
there is potentially another thing affecting performance - Compressed extent

Hi,
Is there some way to cancel a device remove operation? I have discovered that
if I reboot that will cancel it, but that's not always possible. What I'm after
is something the same as cancelling scrub.
I keep running into situations where I want to pause a remove operation for
speed reasons.

Another way to defrag the file is to move the file to another disk and then
move it back. I've had trouble with virtual machine disks before (Windows
server raw) and this has fixed the problem.
FYI 3.17.2 and beyond seems much better now. No crazy slow downs.
Paul.

As the topic says, btrfs check - Couldn't open file system. Check runs fine on
all btrfs volumes except one - "Backup". There is nothing special about it, it
uses the same options as all the other ones (raid1, compress).

Hi Nguyen,
Perhaps a better idea would be to use a low-cost low-power som module to run
Linux and btrfs code, and use an FPGA/ASIC to offload
compression/encryption/checksums and to possibly act as a raid controller.
Since btrfs will be under heavy development for the foreseeable future I doubt
