Hi,
the situation:
Label: 'RootFS'=C2=A0 uuid: c87975a0-a575-405e-9890-d3f7f25bbd96
=C2=A0=C2=A0=C2=A0 Total devices 2 FS bytes used 284.98GB
=C2=A0=C2=A0=C2=A0 devid=C2=A0=C2=A0=C2=A0 2 size 311.82GB used 286.51G=
B path /dev/sdb3
=C2=A0=C2=A0=C2=A0 devid=C2=A0=C2=A0=C2=A0 1 size 897.76GB used 286.51G=
B path /dev/sda3
RootFS created when sda3 was 897.76GB and sdb3 311.82GB.
I have now freed other space on sdb. So I deleted sdb3 and recreated
it occupying all available space.
Disk /dev/sdb: 2000 GB, 2000396321280 bytes
255 heads, 63 sectors/track, 243201 cylinders
Units =3D cylinders of 16065 * 512 =3D 8225280 bytes
/dev/sdb3=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=

same as

368837=C2=A0=C2=A0 83=C2=A0 Linux
# ./btrfs filesystem resize max /mnt/RootFS
Resize '/mnt/RootFS' of 'max'
on dmesg I get only:
[=C2=A0 657.438464] btrfs: new size for /dev/sda3 is 963962208256
# ./btrfs fi sh

B path /dev/sda3
/dev/sdb3 is the same.
How can I resize /dev/sdb3?

I think the syntax you need is btrfs fi resize max /mnt/RootFS:2
But I could be wrong. If it works, can you add it to the UseCases
page on the wiki, please?

Hash: SHA1
I submitted some patches a few weeks ago to fix this so you specify
the device normally instead of looking up the internal devid and
passing it as an undocumented prefix to the size parameter. Hopefully
they can get merged sometime soon.
