Inappropriate ioctl for device

Inappropriate ioctl for device

[Mojtaba]

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:

root@s2:/# uname -a

I've successfully run balance on this system once a few days ago
however after that I'm getting Inappropriate ioctl


Thanks

That's a way too old kernel to be running Btrfs on. You should be
running on at least the Jessie 3.16 kernel.

This appears to be Debian Wheezy.  You can use "cat /etc/debian_version" to
verify(7.n = Wheezy).  There is a backports kernel which is version 3.16
that you can upgrade to.  You will need to add the wheezy backports
repository to apt.

Note:  Watch the dependencies during the upgrade.  You may want to choose
  initramfs-tools from backports rather than dracut which was offered as a
  replacement for initramfs-tools.
