Hi, all,
I ran into a situation that no useful information can be found over
the internet...
I'm using 3.6.2 + btrfs git compiled using dkms, and I have a 300GB
btrfs /home and 50GB btrfs /:
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes

At first, it was NetworkManager that took 80000ms to load( a btrfs
only problem),
after some debugging. I added comment="systemd.automount" to my btrfs partition.
then the only problem left is that kernel+userspace took 135s to
initialize then -.mount
and all other systemd service can continue:

And Frederic said it seemed to be a known bug that need to clear_cache
for 3.4+ kernel.
I did. but the problem still exist.
The original bug report is here:
https://bugzilla.novell.com/show_bug.cgi?id=776563
So anyone can help me debugging this?
Thanks

Usually when btrfs is slow to mount, or slow right after a mount it is
because we're regenerating the free space cache. This is slow enough
that you should be able to see the free space cache threads active even
after the initial boot is done.
The good news is that you should be able to just let them finish
generating the cache and then the problem should go away.
If it isn't the free space cache, it'll be a fragmentation problem. The
easiest way to tell the difference is to get a few sysrq-w snapshots
during the boot.

HI,Chris,
yes...I did regenerate free_space last time Frederic told me to.
the next boot after removing clear_cache from fstab is super slow. but
after that boot,
kernel still needs 135s to load...

How can I "get a few sysrq-w snapshots" please?
My btrfs is automatically created during openSUSE install, so I don't
know which command I can use to do so...please forgive my freshness
and stupidity...

Hi, Chris,
with some help from openSUSE community, I learnt what's sysrq
snapshots(alt+printscreen+w in tty1)...
and here's my log:
http://paste.opensuse.org/31094916
can you help look through this?
Many thanks!
Marguerite

You need to hit alt-sysrq-w during the slowness you're trying to
instrument; the pastebin is from an hour later.
Also, next time just put the output directly in the email, that way
it's permanently around to look at and search for.

Thanks for teaching me the rules, cwillu!
I'll do it right now!

It appears space_cache isn't enabled on your rootfs; can you do a
"mount / -o remount,space_cache", sync a couple times, make some
coffee, and then reboot, and see if it's better?
You should see two instances of "btrfs: disk space caching is enabled"
in your dmesg, one for / and the second for /home.
Also, make sure to reply-all so that others interested can still follow along.

like this

That would work, but it's only necessary to mount with it once (and
it's probably been done already with /home), hence the -o
remount,space_cache

Marvelous! cwillu, you're the most brilliant man I've ever seen in this world!
I can't find a most suitable word to say thank you!
You saved my life! I mean, 1 year and a half's struggling now comes to an end!
Hugggggggggggg!
Can you tell me what my problem actually is? do you or do I need a
patch of something added to the code base? I mean, I'm an openSUSE
Memeber, our distro didn't have my:
default,space_cache,comment="systemd.automount" and 0 1
set by default, actually it was:
default 0 2
so is there anything I can do to make this happiness come to everyone
in my distribution?
Huggggg againnn!

Now my kernel loads in 10s, another 4s for userspace...then -.mount
and all the systemd services.
It boots like an animal!

Without space_cache (once), btrfs has to repopulate that information
the slow way every mount; with it, it can just load the data from the
last unmount (modulo some consistency checks).
The setting is sticky, so you don't actually need it in fstab any more
(although it won't hurt anything either).

Thanks, cwillu!
I transfer the message to openSUSE bugzilla and ask them help making
that happen by default in openSUSE.

Apparently mkfs.btrfs does set it by default now, so perhaps your
filesystem predates the change, or suse's btrfs-progs is too old.
mkfs.btrfs /dev/whatever followed by mounting with no options should
print "btrfs: disk space caching is enabled" to dmesg if your mkfs is
new enough, if you wish to test.
