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: [ 72.729685] btrfs: resizer unable to find device 1 $ sudo btrfs fi df / Data: total=34.00GB, used=17.79GB System, DUP: total=64.00MB, used=20.00KB Metadata, DUP: total=33.50GB, used=394.93MB $ sudo btrfs fi sh Label: none uuid: b0ad55e2-09e0-4658-8cab-d2e11ba03753 Total devices 1 FS bytes used 17.18GB devid 2 size 1.62TB used 101.12GB path /dev/sdc4 $ uname -r 3.3.2-1.fc16.x86_64 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: [ 1661.933884] btrfs: resizing devid 2 [ 1661.933895] btrfs: new size for /dev/sdc4 is 1995564908544 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
