Hallo, Hugo,

btrfs device delete <device> <path>

My (planned) usual work (once a year or so):
btrfs device add <biggerdevice> <path>
btrfs filesystem balance <path>
btrfs device delete <smallerdevice> <path>
And the "devices" are (p.e.) /dev/sdj1, /dev/sdk1 etc. (partitions on a
device).
Therefor I can see some informations via (p.e.)
blkid /dev/sdj1
I prefer LABELling the devices/partitions, and then I'd seen that the
option "-L" makes problems when I use it for more than 1 device/
partition.
With other file systems there's no real problem with the same label for
several partitions - it doesn't work. But btrfs bundles these partitions
(perhaps sometimes/most times regardless of the labels of the other
partitions).
Viele Gruesse!
Helmut
