Re: LABEL only 1 device

Hallo, Hugo,

Du meintest am 26.02.12:

Mounting seems to be no problem, but (p.e.) "delete" doesn't kill
the btrfs informations shown with (p.e.) "blkid /dev/sdy1",
especially it doesn't delete the label.

   What do you mean by "delete" here?

   btrfs device delete <device> <path>

   The label is a *filesystem* label, not a label for the block
device(s) it lives on, so it doesn't make much sense to talk about
putting an FS label on only one of the devices that the FS is on.

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!
