As the title suggests, running the df command on a subvolume doesn't return a
filesystem. I'm not sure where the problem lies or if anyone else has noticed
this. Some programs fail to detect free space as a result.

The problem
I had a number of similar btrfs balance crashes in the past few days,
but the disk wasn't full. You should try tailing the system logs from
a remote machine when it happens. You'll likely see some bug info
before the system dies and becomes unusable.
The issue I encountered is described @

-progs git repo shows that
`stat("missing")` is called, which of course fails since missing isn't
a block device. Nothing other then `btrfs replace` seemed intuitive
and all the docs mention the older command. What's the move?
Thanks!

What issues would arise if ssd mode is activated because of a block layer
setting the rotational flag to zero? This happens for me running btrfs on
bcache. Would it be beneficial to pass the no_ssd flag?

ecause you can add/remove/resize the cache
without recreating the filesystem. If you're interested, take a peek
at the man page for lvmcache.

Works here. Extents are stable after a balance.

I'm currently running a 1GB raid1 btrfs /boot with no problems.
Also, I think the current grub2 has lzo support.

I've been having good luck with my /boot on a separate 1GB RAID1 btrfs
filesystem using grub2 (2 disks only! I wouldn't try it with 3). I
should note, however, that I'm NOT using compression on this volume
because if I remember correctly it may not play well with grub (maybe
that was just lzo thou
at was just lzo though) and
I'm also not using subvolumes either for the same reason.

Thanks for the clarification. I was under the impression that mounting
multiple subvolumes with different options had been implemented. Perhaps
someday it will be although for now there are more pressing issues.
I appreciate everyone's hard work and look forward to the continued development
of btrfs.
many thanks,
