I was trying to make sense out of this:
gargamel:~# lsattr
lsattr: Inappropriate ioctl for device While reading flags on ./satapmtool
lsattr: Inappropriate ioctl for device While reading flags on ./usbreset
As well as the btrfs send issue I reported:
gargamel:/mnt/btrfs_pool1# btrfs send media_ro.20140222_11:12:53 | less
At subvol media_ro.20140222_11:12:53
ERROR: send ioctl failed with -25: Inappropriate ioctl for device
I was trying to figure out why it was failing on one system while it was working
on my other ones with the same kernel.
In the end I pinned it down to this:
3.13.5's kernel/userland interface fails if my kernel is 64bit and my
userland 32bit.
lsattr and btrfs send, and maybe more things fail, but they started working
the moment I updated my kernel to 32bit
Is this difficult to fix?
Do I need to file bugs with some folks, or this mail is enough?
Thanks,
Marc

This is a known issue. There's patches in the pipeline for 32-bit
userspace on a 64-bit kernel, already.

If you mean my recent patch, that's only for receive. I've not
noticed any other issues on my 32/64 system, but I've not done much
with it either (with btrfs, it's only really used for btrfs receive --
everything else is ext4).

Thanks. Yes, I believe that's what I had in mind. So apparently there's
more needed. (I /think/ I might have seen at least one additional patch
float by for 32/64, but as it's out of my usage domain I'm not paying
/that/ much attention to it, so perhaps not.)

In the meantime, if that helps someone, on debian it's trivial to get
64bit for some packages. All I had to do was this:
gargamel:/usr/src# dpkg --add-architecture amd64
gargamel:/usr/src# dpkg --print-foreign-architectures
amd64
gargamel:/usr/src# apt-get install e2fsprogs:amd64 btrfs-tools:amd64
And that's it.
Now I'm back in business with a 64bit kernel.
