Btrfs labels

[Patrick O'Callaghan]

I changed a Btrfs label:

$ sudo btrfs filesystem label /storage
home       <------------ Before
[poc@Bree Working]$ sudo btrfs filesystem label /storage storage
[poc@Bree Working]$ sudo btrfs filesystem label /storage
storage    <---------- After

But:

$ lsblk -af
NAME     FSTYPE FSVER LABEL                 UUID                                 FSAVAIL
FSUSE% MOUNTPOINT
[...]
sdc                                                                                       
     
└─sdc1   btrfs        home                  6496d6da-6b7a-4cdd-9bb8-767c08d1c84e  951.9G  
 49% /storage
                      ^^^^

Has the label changed or not?

Did you try:

partprobe /dev/sdc

?

# partprobe -s /dev/sdc
/dev/sdc: msdos partitions 1

I meant to say "partprobe /dev/sdc" so that you can, afterwards, see the
*correct* label with lsblk...

I see. Yes, that worked, thanks.
