Hello!
Is this output in slabtop normal after a few days uptime with a daily rsync
(btrfs to btrfs) and some compiling (gentoo emerge):
Active / Total Objects (% used) : 1120836 / 1810907 (61,9%)
Active / Total Slabs (% used) : 42492 / 42492 (100,0%)
Active / Total Caches (% used) : 72 / 101 (71,3%)
Active / Total Size (% used) : 253898,56K / 324674,92K (78,2%)
Minimum / Average / Maximum Object : 0,01K / 0,18K / 15,69K
OBJS ACTIVE USE OBJ SIZE SLABS OBJ/SLAB CACHE SIZE NAME
109220 99107 90% 0,98K 6830 16 109280K btrfs_inode
If I close all my desktop programs, my system stays at +12 GB RAM usage
while after a fresh boot it has 12+ GB free (of 16 GB). Cache stays low at 2
GB while after a few minutes uptime cache is about 5 GB.
This looks like memory leaking somewhere. Top does not show where all this
memory went (biggest process is 500 MB RES, next is 200 MB and lower).
Thanks,
Kai

I probably have the same problem over here, after about 2 weeks of
random read/write it seems my memory and swap get almost full and even
after killing all process and getting in single user mode, memory
won't free up. Would you happen to have quota enabled too? Kernel is
3.11.4

FWIW, seeing nothing like that here, no quota/qgroups enabled.
But there's definitely something not right with qgroups at this time.
First, a lot of folks with it enabled are reporting negative numbers
which shouldn't be there, and second, all or very nearly all the huge
memory usage issues reported seem to be from qgroups-enabled people.
So I'd call the qgroups feature broken at this time. Don't use it if you
can avoid it (but be aware that turning it off triggers the memory issue
and ultimate crashing for some, so preferably turn it off when you're
rebooting anyway), and if you really do need quotas for your use-case,
you may be better off on a non-btrfs filesystem for the time being.
(Of course btrfs is still listed as experimental in any case, so one
shouldn't be surprised if this sort of thing happens from time to time or
with some features.)

I agree. I made a page about Quotas on the wiki so to document my
findings as documentation is really sparse. If you consult the section
Known issues, you will find those:
* To get accurate information, you must issue a sync before using the
qgroup show command.
* The qgroup show command is missing some information, for example you
cannot see which subvolume is part of a parent qgroup.
* Creating a qgroup from an existing directory will show a 0 usage
until a full filesystem quota rescan is issued.
* Using btrfs subvolume delete will break qgroup unshared space usage.
* After deleting a subvolume, you must manually delete the associated qgroup.
Knowing this, if you create a qgroup after some files have been added
to a subvolume, those never get accounted for until you rescan the
whole volume. This means that if you manage to delete enough "not
accounted for" files, you get negative numbers.

No, quota is off for me. This is a three-device btrfs desktop system. Quota
has no real use for me (except maybe for subvolume accounting).
I first thought this may be related to having zcache enabled, turned it off.
But anything that changed is when memory stress arises my system stays more
responsible and does not go havoc on the CPU.
I switched to zswap instead, since then swap usage is much lower. But still
it does not help if memory is mysteriously used somewhere. At least IO
stress is lower now with that setting and I am better able to cleanly shut
down programs and the system for reboot.
Regards,
Kai

This is true in some extent.
qgroup accounting info(stored in disk) only update when commting
transaction.
Anyway, by triggering a sync is a little overhead. maybe we can
implement an sync ioctl for quota sync.

This has been implemented in the latest chris's integration branch,you
can use
btrfs qgroup show -p <mnt>
> * Creating a qgroup from an existing directory will show a 0 usage

In the latest kernel. if you enable quota, it will create qgroup
for every existed subvolume, and then rescan will be triggered
automatically.(only happens in rescanning)
When creating a subvolume, you can use
btrfs sub create -i <pid> <mnt>
this will add a parent qgroup for a subvolume the moment it was created,
we can avoid rescanning for this case.
However, if you create a parent qgroup and then assign subvolume qgroup
to this parent qgroup online, you have to rescan.

This is true, for now, deleting a subvolume will cause wrong qgroup
accounting.
Jan sent a patch for this recently, hopely this problem can be solved as
soon as
possible.
I have planed to make a patch to drop associated qgroup when deleting a
subvolume
only if qgroup accounting problem has been fixed.

That's an interesting point. I've been cautious about enabling skinny
extents as well, and haven't enabled them here. (Nothing major, just a
couple early reports that I expect have long been worked out by now, but
I decided giving them a few more kernel releases to mature was probably a
good idea.)
So it'd be interesting to see if there's a correlation between skinny
extents and the memory issues as well, as there seems to be between
qgroups and the memory issues.

For me it started late 3.9 if I remember right. But I'm pretty sure it
startet with 3.10 which I mostly upgraded to for using skinny extents. While
skinny extents has helped subjective performance a little bit I since
experience the problem with ever increasing RAM usage - up to the point of
15 GB swap, full RAM, and almost none of it is used for caching.
I wonder if there is a way to track where this "lost" memory is gone. Top
shows no memory hogs. Slabtop shows some high numbers but nothing really
impressive. It's just used for nothing it seems.

Kai

I experience the same daily (out of memory, server dying); sometimes
several times daily.
It's a *big* downer.
I use 3.12-rc7, but I had this issue with earlier kernels, too.
Yes, I have qgroups enabled.
A bit desperate, I've started dumping various system parameters (free,
uptime, ps, top, /proc/meminfo etc.) every minute - memory usage can
jump from some 8 GB to 32 GB within one minute; a minute later the
system is no longer responsive and has to be hard resetted.
Example - free-2013-10-29-03:29:01
total used free shared buffers cached
Mem: 32638388 32484484 153904 0 4960 24122452
-/+ buffers/cache: 8357072 24281316
Swap: 16776116 132 16775984
free-2013-10-29-03:30:01
total used free shared buffers cached
Mem: 32638388 32473636 164752 0 544 1191896
-/+ buffers/cache: 31281196 1357192
Swap: 16776116 408 16775708
What would cause such a huge memory usage jump?
top for the same two minutes; no userspace process is using the memory.
First one - we're using ~8 GB RAM, the second one - all 32 GB is used.
