Back story:
I started my pool with a 200gb partition at the end of my drive (sdc5)
, until I was able to clear out the data at the beginning of my drive.
When I was ready, I ran `btrfs dev add /dev/sdc4 /` then `btrfs dev
del /dev/sdc5 /`,
$ sudo btrfs fi resize max /
Resize '/' of 'max'
ERROR: unable to resize '/' - Invalid argument
in dmesg i see:
[ =A0 72.729685] btrfs: resizer unable to find device 1
$ sudo btrfs fi df /

btrfs-progs version is current git master ( commit 1957076 )
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:

Hrm, if we're using filesystem resize max we should probably just max o=
ut 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.
Thanks,
Ilya

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

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,
Ilya

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.
