Created attachment 781851 [details] Error report. Description of problem: When I have tried to upgrade from Fedora 18 to 19 with Fedup, at the moment of booting there is an error with btrfs "mount: wrong fs type, bad option, bad superblock on /dev/sda3, [ 5.898988] Portatil mount[121]: missing codepage or helper program, or other error [ 5.899536] Portatil mount[121]: In some cases useful info is found in syslog - try [ 5.900109] Portatil mount[121]: dmesg | tail or so. [ 5.896570] Portatil kernel: btrfs: 'root' is not a valid subvolume"t I managed to upgrade directly from yum, but at the moment of boot same error with the kernel-3.10.3-300.fc19.x86_64, but when I try to boot with any kernel from fc18 no problem. What it's the problem, please some help. Version-Release number of selected component (if applicable): Fedora 19 How reproducible: Every single time. Steps to Reproduce: 1.Trying to boot with kernel-3.10.3-300.fc19.x86_64 2.Error Actual results: Can't boot with kernel-3.10.3-300.fc19.x86_64 Expected results: Normal boot. Additional info: Here it's my fstab "UUID=ec03f2a1-4839-441a-8401-357e6b6f3b34 / btrfs subvol=root,compress=lzo 1 1 UUID=e37e0d99-3090-43bb-a19e-b075935cadbd /boot ext4 defaults 1 1 UUID=ec03f2a1-4839-441a-8401-357e6b6f3b34 /home btrfs subvol=home,compress=lzo 1 2 UUID=f307b1bf-dfc5-4445-a9f2-8de99dbbf988 swap swap defaults 0 0"
I might have the same problem, fedup can't mount my multi-device btrfs filesystem. I noticed the line [ 5.896570] Portatil kernel: btrfs: 'root' is not a valid subvolume in the attachment. When I boot up the unupgraded fedora 18 and run "btrfs subv list /" I get no output. When I run "btrfs subv get-default /" i get the output "ID 5 (FS_TREE)", this suggests that my default subvolume does not have any name, which might be incompatible with newer versions of btrfs.
*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 19 kernel bugs. Fedora 19 has now been rebased to 3.11.1-200.fc19. Please test this kernel update and let us know if you issue has been resolved or if it is still present with the newer kernel. If you experience different issues, please open a new bug report for those.
If you are still seeing issues please try reproducing on btrfs-next and file a bugzilla at bugzilla.kernel.org and set the component to btrfs.
Sorry but i can't reproduce the bug beacuse i've done a clean install of Fedora 19 changing the whole filesystem to Ext4.
