Hi, I reported a bug to anaconda (rhbz 901905), but it might be btfs related. Anaconda does this: 18:49:10,317 INFO program: Running... mkfs.btrfs --data=single --label=fedora /dev/vdb1 /dev/vdc1 /dev/vdd1 /dev/vde1 18:49:10,742 INFO program: 18:49:10,746 INFO program: WARNING! - Btrfs Btrfs v0.19 IS EXPERIMENTAL 18:49:10,746 INFO program: WARNING! - see http://btrfs.wiki.kernel.org before using 18:49:10,748 INFO program: 18:49:10,749 INFO program: SMALL VOLUME: forcing mixed metadata/data groups 18:49:10,750 INFO program: Created a data/metadata chunk of size 8388608 18:49:10,750 INFO program: adding device /dev/vdc1 id 2 18:49:10,751 INFO program: adding device /dev/vdd1 id 3 18:49:10,752 INFO program: adding device /dev/vde1 id 4 18:49:10,752 INFO program: fs created label fedora on /dev/vdb1 18:49:10,753 INFO program: nodesize 4096 leafsize 4096 sectorsize 4096 size 2.93GB 18:49:10,754 INFO program: Btrfs Btrfs v0.19 18:49:10,987 INFO program: Running... udevadm settle --timeout=300 18:49:11,007 INFO program: Running... udevadm settle --timeout=300 18:49:11,036 INFO program: Running... udevadm settle --timeout=300 18:49:11,070 INFO program: Running... udevadm settle --timeout=300 21:49:11,121 INFO program: Running... /bin/mount -n -t btrfs -o defaults /dev/vdb1 /tmp/btrfs-tmp.5205bBZQ 21:49:11,135 ERR program: mount: wrong fs type, bad option, bad superblock on /dev/vdb1, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so In the syslog file this is shown: 21:49:10,371 INFO kernel:[ 435.624404] device label fedora devid 1 transid 3 /dev/vdb1 21:49:10,371 INFO kernel:[ 435.624720] device label fedora devid 1 transid 3 /dev/vdb1 21:49:10,385 INFO kernel:[ 435.638653] device label fedora devid 1 transid 3 /dev/vdb1 21:49:10,396 INFO kernel:[ 435.649839] device label fedora devid 2 transid 3 /dev/vdc1 21:49:10,404 INFO kernel:[ 435.657442] device label fedora devid 3 transid 3 /dev/vdd1 21:49:10,434 INFO kernel:[ 435.687677] device label fedora devid 4 transid 3 /dev/vde1 21:49:10,746 INFO kernel:[ 435.999309] device label fedora devid 1 transid 4 /dev/vdb1 21:49:10,918 INFO kernel:[ 436.171992] device label fedora devid 3 transid 4 /dev/vdd1 21:49:10,925 INFO kernel:[ 436.178937] device label fedora devid 3 transid 4 /dev/vdd1 21:49:10,928 INFO kernel:[ 436.181545] device label fedora devid 4 transid 4 /dev/vde1 21:49:10,929 INFO kernel:[ 436.182475] device label fedora devid 1 transid 4 /dev/vdc1 21:49:10,930 INFO kernel:[ 436.183409] device label fedora devid 4 transid 4 /dev/vde1 21:49:10,932 INFO kernel:[ 436.185171] device label fedora devid 1 transid 4 /dev/vdc1 21:49:10,971 INFO kernel:[ 436.224843] device label fedora devid 1 transid 4 /dev/vdb1 21:49:11,130 INFO kernel:[ 436.383110] device label fedora devid 1 transid 4 /dev/vdb1 21:49:11,133 INFO kernel:[ 436.386297] btrfs: disk space caching is enabled 21:49:11,133 WARNING kernel:[ 436.386697] btrfs: failed to read chunk tree on vde1 21:49:11,134 WARNING kernel:[ 436.387183] btrfs: open_ctree failed I booted again and did both the mk.btrfs and the mount manually and i got the same error.
