Hi, I create a raid-1 btrfs with the following command. [root@localhost ~]# fdisk -l /dev/sdb Disk /dev/sdb: 320.0 GB, 320072933376 bytes 255 heads, 63 sectors/track, 38913 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0xb44829ea Device Boot Start End Blocks Id System /dev/sdb1 1 4863 39062016 83 Linux /dev/sdb2 4864 9726 39062047+ 83 Linux /dev/sdb3 9727 38905 234375905+ f W95 Ext'd (LBA) /dev/sdb5 9727 14590 39063374 83 Linux /dev/sdb6 14590 19453 39068690+ 7 HPFS/NTFS /dev/sdb7 19454 29178 78116031 83 Linux /dev/sdb8 29179 31610 19535008+ 83 Linux /dev/sdb9 31611 34041 19526976 83 Linux /dev/sdb10 34042 36473 19535008+ 83 Linux /dev/sdb11 36474 38904 19526976 83 Linux [root@localhost ~]# mkfs.btrfs -m raid1 /dev/sdb8 /dev/sdb9 /dev/sdb10 /dev/sdb11 adding device /dev/sdb9 id 2 adding device /dev/sdb10 id 3 adding device /dev/sdb11 id 4 fs created label (null) on /dev/sdb8 nodesize 4096 leafsize 4096 sectorsize 4096 size 74.50GB Btrfs v0.16-29-g0d53b21 [root@localhost ~]# mount -t btrfs /dev/sdb8 /mnt/btrfs[root@localhost ~]# df Filesystem 1K-blocks Used Available Use% Mounted on ... /dev/sdb8 78123968 28 78123940 1% /mnt/btrfs I think the partition size is no correct since this is a raid-1 partition. The size should be half. Is this a bug? -Shen -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
