Hallo, linux-btrfs,
I have problems with btrfs labels.
My way:
2-TByte-disk:
mkfs.btrs LABEL=MM2 /dev/sdd2
worked.
Mounting "mount LABEL=MM2 /srv/MM" worked.
Additional 1.5-TByte-Disk:
btrfs add device /dev/sdc3 /srv/MM
... balance ...
worked.
findfs LABEL=MM2
shows "/dev/sdd2" (the first partition)
file -s /dev/sdd2
file -s /dev/sdc3
shows "LABEL=MM2" for both partitions (that's not good).
Unmounting "/srv/MM" and
mount LABEL=MM2 /srv/MM
doesn't work now, it tries to mount /dev/sdd2 and mourns.
mount /dev/sdd2 /srv/MM
shows the same error message,
mount /dev/sdc3 /srv/MM
(mounting the added partition) works fine, the whole space is available.
But what can I do with the 2 identical labels? How can I delete (or
change) the label of the first btrfs partition?
----------------------------
By the way:
"df" shows about 3.4 TByte usable space (2 TByte and 1.5 TByte), but
btrfs filesystem df /srv/MM
tells
Data: total=2.70TB, used=1.64TB
I'm missing about 0.7 TByte!
Viele Gruesse!
Helmut
