I've tried running a btrfs resize but it hasn't changed anything.
What was the exact resize command you used?
The docs say:
# btrfs filesystem resize amount /mount-point
So I said:
btrfs filesystem resize max /
and Linux says:
Resize '/' of 'max'
Which doesn't really make any sense...
Sorted. The special sauce was to specify the device id, so: # btrfs filesystem show / Label: none uuid: 3826b465-0224-41df-9e1e-182d5eb68904 Total devices 4 FS bytes used 5.15TiB devid 1 size 2.73TiB used 2.73TiB path /dev/sda3 devid 2 size 2.73TiB used 2.73TiB path /dev/sdb3 devid 3 size 2.73TiB used 2.73TiB path /dev/sdc3 devid 4 size 2.73TiB used 2.73TiB path /dev/sde3 # btrfs filesystem resize 4:max / Resize '/' of '4:max' # btrfs filesystem show / Label: none uuid: 3826b465-0224-41df-9e1e-182d5eb68904 Total devices 4 FS bytes used 5.15TiB devid 1 size 2.73TiB used 2.73TiB path /dev/sda3 devid 2 size 2.73TiB used 2.73TiB path /dev/sdb3 devid 3 size 2.73TiB used 2.73TiB path /dev/sdc3 devid 4 size 5.46TiB used 2.73TiB path /dev/sde3 w00t!
