[opensuse-factory] openSUSE 13.1 M3 update btrfsprogs to support RAID5
Hi, since Kernel 3.9 btrfs supports RAID5 (experimental). Unfortunately M3 ships with btrfsprogs 0.19, which do not support the RAID5 feature. I compiled btrfs-progs from git://git.kernel.org/pub/scm/linux/kernel/git/mason/btrfs-progs.git and created a RAID5 with the new version. Would it be possible to integrate a more recent version in openSUSE 13.1? Below you will find my short test: # ./mkfs.btrfs -f -d raid5 -m raid5 -L myRAID5 /dev/sdb1 /dev/sdc1 /dev/sdd1 WARNING! - Btrfs v0.20-rc1-358-g194aa4a IS EXPERIMENTAL WARNING! - see http://btrfs.wiki.kernel.org before using adding device /dev/sdc1 id 2 adding device /dev/sdd1 id 3 Setting RAID5/6 feature flag fs created label myRAID5 on /dev/sdb1 nodesize 4096 leafsize 4096 sectorsize 4096 size 24.00GB Btrfs v0.20-rc1-358-g194aa4a # mount /dev/sdb1 /mnt/ # df -h /mnt/ Filesystem Size Used Avail Use% Mounted on /dev/sdb1 24G 28K 20G 1% /mnt # ./btrfs filesystem df /mnt Data: total=8.00MB, used=0.00 Data, RAID5: total=2.00GB, used=0.00 System: total=4.00MB, used=0.00 System, RAID5: total=16.00MB, used=4.00KB Metadata: total=8.00MB, used=0.00 Metadata, RAID5: total=2.00GB, used=24.00KB # ./btrfs filesystem show /dev/sdb1 Label: 'myRAID5' uuid: 7a975562-c571-4a73-b617-a8c299e151cb Total devices 3 FS bytes used 28.00KB devid 3 size 8.00GB used 2.01GB path /dev/sdd1 devid 2 size 8.00GB used 2.01GB path /dev/sdc1 devid 1 size 8.00GB used 2.03GB path /dev/sdb1 Btrfs v0.20-rc1-358-g194aa4a Regards, Ulf -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
