Hallo, Goffredo,
Du meintest am 20.01.11:
> To add another disk you don't have to run mkfs.btrfs. For example:
> # add the first disk
> mkfs.btrfs /dev/sdb
> # mount the disk
> mount /dev/sdb /media/backups
> # add another disk to the first one
> btrfs device add /dev/sdc /media/backup
^backups
> Note1: the filesystem has to be mounted
> Note2: the medatada will be in raid1, the data in raid0
And there seems to be an error; some options tell the sum of the sizes
of /dev/sdb and /dev/sdc as available size, but perhaps you can only use
the size of the smaller of the two devices - the system seems to work in
a kind of RAID1.
The error is known but not yet fixed.
Viele Gruesse!
Helmut
