The current writeable clone (announced 11th November on the linux- btrfs list by David Sterba) is here:
I've just created a BTRFS filesystem with the following command: mkfs.btrfs -m raid1 -d raid1 /dev/vg0/raid? Where the raida and raidb devices are each 2G logical volumes. # df -h . Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg0-raida 4.0G 56K 3.6G 1% /mnt/tmp # dd if=/dev/urandom of=test bs=1024k count=512 ; df -h . 512+0 records in 512+0 records out 536870912 bytes (537 MB) copied, 73.3964 s, 7.3 MB/s Filesystem Size Used Avail Use% Mounted on /dev/mapper/vg0-raida 4.0G 678M 2.9G 19% /mnt/tmp It seems a bit bogus to report the Size of the filesystem as 4G when there are 2*2G devices in a RAID-1. I created a few more big random files and the filesystem ran out of space after 1.8G of data was stored, but it reported 3.1G used and 558M free. :( -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
