Can anyone boot a system using btrfs root with linux 3.14 or newer?
Because I can't.
I'm trying to move some 3.13.x based systems to 3.14.x and the kernel panics
during boot. It says to append a correct root=sdaX partition, but the one
provided is correct, because if use 3.13.x with the same kernel command line
- the system boots fine.
The thing is - there is an ext2 /boot partition and root / is btrfs, like
so:
# cat /etc/fstab
#
# /etc/fstab: static file system information
#
# <file system> <dir> <type> <options> <dump>
<pass>
#/dev/#REISERFS_ROOT# / reiserfs defaults 0 0
#/dev/#EXT3FS_ROOT# / ext3 defaults 0 1
/dev/sda2 / btrfs relatime,compress=zlib 0 0
/dev/sda1 /boot ext4 defaults 0 1
#/dev/#JFS_ROOT# / jfs defaults 1 1
Here is my relevant GRUB config file part:
#menuentry 0
title Linux
root (hd0,0)
kernel /vmlinuz rw root=/dev/sda2 vga=6 raid=noautodetect
And for the record - I used the same kernel config as the one from 3.13.x -
I just copied my old .config file over to linux 3.14.x sources and did a
"make olddefconfig" and compiled my kernel, just as I did with all previous
ones...
Ideas?
P.S. Please, CC me - I'm not subscribed.

Yes I do.

It works fine for me.

My guess is that you have btrfs compiled as a module, it then needs to be in
an initrd, and you either haven't built it and put it in the right place, or
grub isn't setup to load that initrd.

That's missing an initrd. Are you absolutely certain then that btrfs is
compiled in the kernel and not as a module?

And the other thing to check here is that if this is a multi-device
filesystem, you need to have your initrd run "btrfs dev scan" before
trying to mount.

Just to clarify - I am using a monolithic kernel built from source, and it has all the stuff it needs to support built-in, and then some. And no modules.
The sources I'm using are the vanilla kernels from Linus and Greg KH downloaded from kernel.org.
Check out the attached config I am using - it’s a kernel I'm running on one server and a couple of virtual machines.
Until now - copying said config and doing a "make oldconfig" or "make olddefconfig" and compiling-then-booting worked fine.
Can it be that for 3.14 it matters which btrfs version/kernel/tools the filesystem was mkfs'd with play a role here? Because if that's it - my filesystem should be very old - now more than a year, come to think about it...

This line looks kinda useless to me. The compress=zlib option won't be
applied at boot and cannot be changed at runtime because AFAIR btrfs does
not allow that yet.
This is because during initial mount by the kernel, /etc/fstab has not yet
been read (and cannot for obvious reasons). The only way around it is to
also append rootflags= to the kernel cmdline. This also explains why in a
few other cases btrfs cannot be mounted, although it should make no
difference in your case except the compress option won't be applied to the
running file system.
Also, you may want to try rootdelay=2 or something similar, it sometimes
help mounting btrfs at boot. But first try the suggestion abount baking the
btrfs module right into the kernel.

That's the working .config.

This should indeed work, this is what I do too.
So now, we're kind of guessing. To save us all time, could you capture a
serial console boot from the running 3.13 and then the failing 3.14.
My guess is that if you diff both you'll likely find what went wrong, but if
not you can post here.
As for the btrfs FS format, it has not changed in a way that new kernels
wouldn't be able to mount an FS from a year ago or more.

Well, for the details - see for example here:
https://bugzilla.kernel.org/attachment.cgi?id=133111
how does a 3.14.1 built the way described earlier fails.
And for that matter - see the whole bugzilla bug entry - I went on and bisected this, using the linux-stable git tree, and after that landed me on the commit that introduces some "shiny new btrfs feature" for 3.14 - I decided my git bisection has gone wrong. And because I reported it on April 17-th and since then there has been no activity on the bugzilla entry besides me updating it - I posted my problem here, for more eyes to see.

See the result of "diff config-v3.14.1-mix64 config-v3.13.11-mix64" in the attached file.

... My understanding is that the compress= option on btrfs *can* be
changed at run time. After remounting with a compress= option, later
writes will be done using the newly selected algorithm.
The compress= option is filesystem-wide, you cannot currently use
different compress= options for different subvolumes. Mounting a
subvolume with a different compress= option will change the compression
algorithm for all mounted subvolumes on that filesystem.
(Note that I wouldn't recommend zlib on most systems as a / filesystem -
it's slow to decompress compared to lzo, so it will cause slower boots
if your disk is reasonably fast.)

Thanks, that helps.
Except, now I'm perplexed.
It indeed shows btrfs loaded and your block device being detected.
However it does not show a btrfs mount error.
I haven't had to debug this in a while, but I'm wondering if you're having a
block device problem.
It may help to look up what error -38 translates into for that mount error.
> And for that matter - see the whole bugzilla bug entry - I went on and bisected this, using the linux-stable git tree, and after that landed me on the commit that introduces some "shiny new btrfs feature" for 3.14 - I decided my git bisection has gone wrong. And because I reported it on April 17-th and since then there has been no activity on the bugzilla entry besides me updating it - I posted my problem here, for more eyes to see.
One easier way to debug this would be to create an initrd for 3.13 and 3.14.
Make sure it works with 3.13 first, then boot 3.14 and see what error you
get.
You'll get an error from mount(8) and not the kernel and you'll be dropped
to a shell, giving you more debug options.

diff -u is your friend ;)
but diff looks reasonable.

Of course, that doesn't mean you didn't find a bug saying otherwise.
If you try from an initrd, it'll make it easier to debug. You don't have to
build a new kernel or make btrfs a module, just mounting a working initrd
and then trying this again with userland tools will help debug.
(alternatively, rescue boot media with your kernel would work too, but
that's likely more work to build than an initrd)
Actually, you could also use your VM setup to boot another linux image
running ext4 as root with your new kernel, setup your existing drive as sdb,
and try to mount it then.

Not more work - just replaced the kernel on the setup/rescue media with mine and the result is the same - see attached image file.

Yeah, I searched before you :) this would require reading the kernel source
to track down -38.

On debian, I just have to run this:
update-initramfs -v -c -k `grep linux-source debian/changelog | awk '{ print $1 }' | sed "s/linux-source-//"`
Then see /etc/initramfs-tools/initramfs.conf
but the defaults should work
Running update-grub2 should give you something like this:
echo 'Loading Linux 3.12.7-amd64-i915-preempt-20131107 ...'

That's not what I meant, I meant a rescue media that boots another
filesystem than you root filesystem.
Then from there, you can use normal userland tools to manually mount your
root filesystem and/or see errors.

I'm trying to boot into the rescue media's environment with my own kernel, but it fails now that my monolithic kernel has no support for initrd whatsoever (or something else missing)!
I guess I’ll leave this testing for tomorrow - getting tired and sleepy now...
Thanks!

So long as no other part of the same volume (including a subvolume) has been mounted, an ro rootfs remounted upon consultation of fstab will result in the fstab mount options being applied to remount. There might be a handful of btrfs options that don't work with remount, but compress isn't one of them. At least on Fedora since the dawn of btrfs, it's been possible to specify compress in fstab and its honored when rootfs is remounted rw.
Also, relatime is default. So the cleaned up mount option for fstab for the above would be merely compress (zlib is the default).

The screen shot provided makes it clear that one of the following kernel parameters is incorrect:
> root=/dev/mapper/cryptroot
> rootflags=subvol=root
So either the dmcrypt volume hasn't been opened, thus isn't available; or rootfs isn't on a subvolume named root found at the top level of the file system. So I'd say this isn't a btrfs problem, rather it's due to some earlier misconfiguration that's preventing rootfs from being mounted.

You'll need an initrd to run cryptsetup (or whatever) to collect a
passphrase and decrypt the volume before you try to mount it. This
sounds like a case for an initrd again.

I think you are confused, that's my config I pasted as an example.
He does not use dmcrypt in his example.

It sounds like either a grub.cfg misconfiguration, or a failure to correctly build the initrd/initramfs. So I'd post the grub.cfg kernel command line for the boot entry that works and the entry that fails, for comparison.
And then also check and see if whatever utility builds your initrd has been upgraded along with your kernel, maybe there's a bug/regression.

I believe the OP mentioned that he's using a distro without initrd,
and that all required modules are built in.

The mount error is popping up after the printk about not being able to
find root. Add rootwait to the command line.

Sorry, that's almost but not quite what I meant to say. The device
detection message is popping up after the printk about not being able to
find root. Add rootwait to the command line.
In other words, the mount is failing before the root device is detected.
rootwait will make us wait (forever) instead of failing.

Today I managed to try adding rootwait to the kernel commandline - the kernel panic with it in place, too.

I just realized that the l gave no way for identifying the particular bugzilla entry. Here it is:

Sorry about that!

Thanks.
But to save us a lot more speculation, can you please try booting a
linux system (either initrd, or another one with a non btrfs root), and
then trying to mount that filesystem from the command line?

Using 3.14.1 perhaps?
I will try to do that now, but if I can't manage to do it today - expect the results tomorrow.
One more detail I managed to rule out today is that my problematic filesystems used subvol-other-than-root as default, made like so:
$ mount /dev/sda2 /sda2 -o relatime,compress=zlib,subvol=system-main-fs
$ btrfs subvolume set-default system-main-fs /sda2
Only using different name for the subvolume.
Anyway - its irrelevant.
I formatted a fresh root as BTRFS, skipped the above, and tried booting 3.14.1 - result was kernel panic. So different default subvolume or not - its not the problem.

So, here is what I did:
My debug VM had:
sda
sda1 200 MB /boot - ext2
sda2 5 GB / - BTRFS
sda3 5 GB / - XFS
sda4 One extra partition used for mangling (XFS).
sda2 and sda3 were mostly the same, except /etc/fstab, for obvious reasons.
I booted 3.14.1 using sda3 as root, and then tried mounting sda2. It went OK, here is what dmesg said:

Ok, that's good news. It indeed rules out that your new kernel cannot mount
an older btrfs filesystem.
At this point, you may have a problem with the device not being available
when btrfs tries to mount it.

So, I'm not sure how many people use btrfs built it vs as a module. Clearly
the code works for mounting your partition, but when built in the kernel,
there seems to be a timing issue.
For reference, you said this was the bug where you found the CL that causes
this change:
https://bugzilla.kernel.org/show_bug.cgi?id=74261
You said using rootwait as recommended by Chris Mason did not help.
What output are you getting when you use this?
By the way, you should be able to define a pseudo serial port in your VM and
specify something like
console=tty0 console=ttyS0,38400n8
on your boot command line.
This will give you serial console output in text that you can cut/paste/diff

Need a way to pinpoint the actual problem then.

Yeah, and an issue that just popped up with kernels >= 3.14. If memory serves - I started using BTRFS on linux 3.6.x, and since then I followed exactly the same method of upgrading the kernel - described in this thread and in the bugzilla entry - and it always "Just Works" TM!

The image file attached to my previous mail applies to both rootwait and no-rootwait cases. Result is always a kernel panic for 3.14.x on BTRFS root. All other filesystem/kernel combos just work either way.

I will try and use this the next time.

For me, with Btrfs not compiled in the kernel, and with an initramfs, on SSD I get Btrfs loaded at 2.4 seconds. On HDD, it still happens by 6-7 seconds.
So without an initrd and with btrfs compiled into the kernel I'd expect to see Btrfs loaded before 12.4 seconds. Is this an SSD? Or HDD, or hardware raid?
I'd like to see the dmesg from the beginning, until "Btrfs Loaded", for both 3.13.11 and 3.14.1 (via serial console output). I think the clue is in the part before Btrfs loaded.
Also can you post a diff of the config file for the working 3.13.11 and not working 3.14.1 kernels?

Well, the actual time doesn't matter - I use this monolithic kernel on both virtual machines as well as a physical server. Up until 3.13.x this arrangement worked flawlessly, now for 3.14.x - everything will be the same except me using BTRFS...

The most recent dmesg dumps were from a virtual machine.

I will try to provide these, but it will have to wait for tomorrow as currently my monolithic kernel .config does not support serial ports, so I will have to reconfigure, recompile both 3.13.x and 3.14.x to test them and provide the requested data.

The requested diff was posted earlier, reattaching once more.

rootwait should mean it waits indefinitely for rootfs to appear, so why does it still kernel panic?
Is the root= parameter using UUID? If not can you try UUID instead of /dev/sda2? For Btrfs this is still the volume UUID, not subvolume UUID.

Thanks for the serial console logs.
I see that you didn't add rootwait to the command line of your 3.14 boot.
Please do that so that we can see that output.
I'm pasting a diff of them for the benefit of others.
The obvious things to me are:
In 3.13 the device appears after btrfs is loaded:

So I don't think the order is it. The biggest difference I'm seeing between the 3.13.11 and 3.14.1 dmesg's provided:
3.13.11:

3.14.1:
[ 3.949312] bio: create slab <bio-1> at 1
[ 3.950942] Btrfs loaded
It's happening much later, and it's right at this point VFS complains:
[ 4.182603] VFS: Cannot open root device "sda2" or unknown-block(8,2): error -38
The 8,2 message is consistent with the kernel not knowing what file system sda2 is. Seems like it's saying "I see sda2, I know you want to use it as root, but I don't know what's there - *poof*" and it panics.
If rootwait alone doesn't work, I wonder if root=uuid=2ba08fbc-4b95-46cc-b638-299f16462620 instead of root=/dev/sda2 will work along with rootwait. It should then wait for that fs uuid to become available, rather than waiting for sda2 to become available.
I vaguely recall there recently being btrfs boot problems with the module compiled in…

Yes, it was with the crc code. I noticed he has compression on and I'm
wondering if we're hitting a similar ordering problem with the zlib init.
The best way to know for sure is to please try with an initrd. If that
does work we'll know it's an init ordering problem and we can track it
down from there.

It does indeed wait, but I did not wait for it - just booted, saw it ended
in
"Waiting for root device uuid=..." and pasted the serial output.
Is it supposed to somehow find its rootfs later?

That's what I'm thinking too...

Everyone: I didn't think of this earlier, when I first saw the thread,
but coming home and catching up after work, I think my subconscious must
have been working on it all day, and even before I read this message, I
was wondering if it might be another variant of that CRC32 problem. I
was impatiently going thru the messages to see if someone mentioned it
before I started another subthread on it... and here it is. =:^
But both crc32 and crc32c are loaded at about the same point in both
kernels, before the filesystem tries to load, so that can't be it.
But your zlib theory looks like a good candidate, Chris (Mason), and my
sysadmin's intuition is behaving like a Geiger counter at Fukishima ATM,
so I think we're on the right track! =:^)

Indeed, altho as I know from experience, reading/writing that is a lot
easier than actually setting up an initr*, if you've not used one in a
decade and haven't the foggiest how to create one. (Being a gentooer
here, I ended up following a recommendation from an only semi-related
gentoo discussion, and setting up dracut for my initr* when I needed one
to support a multi-device btrfs rootfs. Wasn't too hard, but I did need
to set aside some undisturbed time to study up on it and get it
configured and working. Since this thread's about a single-device btrfs
rootfs, he got away without one until now, but...)
Meanwhile, if an initr* bypasses the issue, the fact that I'm running a
multi-device btrfs root here, and thus an initr*, would explain why I
hadn't run into the problem, here... There goes that Geiger counter
again!
