Hallo, Hugo, Du meintest am 10.11.10: >> 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). > No, this is both good and correct. You've got a single filesystem > spanning multiple block devices. The *filesystem* possesses the > label, and with btrfs you can mount the filesystem using *any* of the > block devices that compose it, so both block devices should indeed > show the FS label, which is what's happening here. >> 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, > What's the error message? What do you get in your kernel logs when > you do this? This should work, so there's something wrong, but it's > (probably) not to do with disk labels. I'll tell tomorrow; the system is just copying more than 1 TByte ... >> ---------------------------- >> >> 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! > In "btrfs filesystem df", the "total" field is the space that has > been allocated to block groups.
