Hi Xeno

Sorry for the typo , I mean : I cant mount BTRFS !

Sorry, I don't have a Btrfs partition. Is it a Btrfs partition on a MBR partition table?

[zappa2009]

Yes my Btrfs-Partition is on a USB-Stick with MBR beside an exfat-Partition. Gparted knows both Partition but Ubuntu16.04.1 or Debian8/9 says unkown filesystem Btrfs.

Hi, I also can't boot with the added btrfs attributes. I think we've been on that road before and I was the one who asked to turn off some features of the fs...

I've been checking this for the last couple of days and when I boot with initrd instead of kernel I get one step further but stuck at a initramfs stage where it says it lacks something crucial with init or sbin/init or something and can't find anything related to root. If I boot with kernel then I get kernel oops.

Now, from the messages you can think this has something to do with other filesystems and specifically a certain conflict with F2FS after enabling the added btrfs attributes. However, those messages might be because of issues with btrfs that goes away if you just enbale the most basic feature like with the 4.7 kernel.

The reason I need those added features is because after an 16.10 update it added a procedure to my boot that dalays it another minute and a half longer while it tries to perform something on the btrfs filesystem/partition - and fails because of a dependency issue (I have everything btrfs related installed on LXQt) which implies it needs something extra from the kernel.

From what I checked one of those options - btrfs integrity check is more for debugging so this might be the first thing that can be turned off. Then we can go from there if it doesn't work.

Another approach might be that the installation itself or the kernel/image lacks something that interacts with btrfs on another level like something initramfs or SystemD does differently as it relates to btrfs (modules?). There is evidence pointing in that direction as well as inconsistencies between kernel, image and installation regarding btrfs specifications and versions. I know that for a fact when Gparted tries to identify btrfs and sees something different than the os while other utilites can actually say they don't see anything. So that also might be a possibily.

The reasonable thing to do, I guess, is start turning off btrfs features one by one and see - not all of them because I need something more to solve my 1.5 minutes delay on boot, or, turning off filesystems that nobody here uses starting with f2fs.

Hi All,

Thanks a lot for testing. What shall I turn off?

Thanks,

For 4.7.1 Deb-stretch LXqt.

I do not use BTRFS so no problem there.

Youtube:

Firefox -----Video No - Audio No
Qupzilla ----Video Yes -Audio No
SMplayer ----Video Yes -Audio Yes

It is still a new distro so not everything is complete.

Just now finished building and booting 4.7.1 built with gcc-4.9.3-14 (Deb 8)
To late to do much testing but sound and video work in SMplayer.

Good night.

Maybe nothing. Check the pic - it looks at /root while nothing partition or sub-volume related is pointing there. It tries to mount /dev/sdc1 on /root even though fstab and mtab points at sub-volume @ which corresponds to / and sub-volume @home which corresponds to /home. Should I add init=bootarg to the kernel/image cfe boot process? will that solve it?

* That is on the initrd image. on the kernel I get a kernel oops fatal error after failing to recognize btrfs.
