Hi. I am having lots of btrfs troubles -- I am using a 4.1.9 kernel and the btrfs programs are 4.2. I did get one sort of a kernel oops which I will attach if the system lets me. Now, let me tell you how this happened. I created the file system on this kernel, created a rootfs subvolume, a usr subvolume and var and home subvolume all at the top level. Now, I then took my root file system, the usr file system and the var and home file systems, took the box offline, booted into a grml cd and did rsync of all that stuff into the new system, changed the fstab and rebooted. The boot partition is an ext4 partition, so that is not involved. I am using dracut and systemd and gentoo. What I got was a mess, a lot of programs returned 203, such as mailman, postgresql, and others. I think programs could not find their files, even though I could do ls and see the names, for instance postgresql said it could not find its .conf, but it seemed there to me. After rebooting back to the old system, I did a scrub and found no errors. So, what could be happening here, things appeared to mount correctly, I used the following fstab ---------- # /etc/fstab: static file system information. # # noatime turns off atimes for increased performance (atimes normally aren't # needed; notail increases performance of ReiserFS (at the expense of storage # efficiency). It's safe to drop the noatime options if you want and to # switch between notail / tail freely. # # The root filesystem should have a pass number of either 0 or 1. # All other filesystems should have a pass number of 0 or greater than 1. # # See the manpage fstab(5) for more information. # # <fs> <mountpoint> <type> <opts> <dump/pass> # NOTE: If your BOOT partition is ReiserFS, add the notail option to opts. #/dev/BOOT /boot ext2 noauto,noatime 1 2 LABEL=main / btrfs defaults,subvol=rootfs 0 1 /dev/sda1 /boot ext4 defaults 0 1 LABEL=swap none swap sw 0 0 #/dev/fd0 /mnt/floppy auto noauto 0 0 # NOTE: The next line is critical for boot! proc /proc proc defaults 0 0 # glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for # POSIX shared memory (shm_open, shm_unlink). # (tmpfs is a dynamically expandable/shrinkable ramdisk, and will # use almost no memory if not populated with files) shm /dev/shm tmpfs nodev,nosuid,noexec 0 0 LABEL=main /usr btrfs defaults,subvol=/usr 0 2 /dev/mapper/linux--files-usr--src /usr/src ext4 defaults 0 2 LABEL=main /tmp btrfs defaults,subvol=/tmp,nodev,nosuid,noexec 0 2 LABEL=main /var btrfs defaults,subvol=/var 0 3 LABEL=main /var/tmp/portage btrfs defaults,subvol=/portage 0 3 LABEL=main /home btrfs defaults,subvol=/home 0 3 /dev/mapper/linux--files-audio /audio ext4 defaults 0 3 /dev/mapper/linux--files-usr--bbs /usr/bbs ext4 defaults 0 3 /dev/mapper/linux--files-hard2 /hard2 ext4 defaults 0 3 /dev/cdrom /mnt/cdrom auto noauto,user 0 0 /dev/mapper/linux--files-scratch /mnt/scratch ext4 defaults 0 3 So, any ideas? Thanks in advance for any suggestions.
