 After writing this email, and searching around the wiki some, I
 discovered the command to resize specific devids,
 
 [antrat@tbox ~]$ sudo btrfs fi resize 2:max /
 Resize '/' of '2:max'
 
 and in dmesg:
 [ 1661.933884] btrfs: resizing devid 2
 [ 1661.933895] btrfs: new size for /dev/sdc4 is 1995564908544

Hrm, if we're using filesystem resize max we should probably just max out all
the devices and not require one specific device, what do you think Ilya?

I'd keep the devid:max syntax for maxing out a single device and add a
new fs:max or similar to resize all devices.  ABI here is just a string,
so I think it can be easily done.

Right I think the devid:max thing is handy for people who want to do specific
things, but I think just a normal btrfs fi resize max should do all devices for
simplicity and easy of use, no need for a fs:max.  Thanks,

Sorry, I misread.  'btrfs fi resize max mnt' should of course resize
the entire FS.  I think this popped up before, at least a couple times.
I'll do it if nobody else wants to.

Thanks,

Agreed, I hadn't thought of it this way in the past, but I can see
people expecting max to mean max out all the devices.
