Hello
I have had some problems with btrfs for some time and it seems no one
else had such problems as I couldn't find anything on the web. All I
could find was either upgrade your kernel or btrfs is experimental so
it's your problem!
The problem is sometimes on some of my servers I get the free space
problem(DF shows free space but I can't create/update and sometimes
delete files)
So as the wiki suggest I try to issue a balance command to get the
Inappropriate ioctl for device
On some of my servers I can successfully use the command one however
after that I get the same error
System is debian wheezy or Jessie.
This is Debian Jessie:

I've successfully run balance on this system once a few days ago

Thanks
