Hi, I also encountered this bug.

However, it started fast, and got slower when the file got bigger.

Maybe it's a n^2 bug?

I included the statistics in rates.tsv.

Still true today. Copying about 180 MB of smaller files (pictures) to a
NTFS partition (filesystem) inside TrueCrypt. It took 20 minutes. I
partition the same mapped device -- format it -- to exFAT, and it takes
26 seconds.

So it took 26 seconds to write that same data at 7.2 MB/s and it took 20
minutes to write the same data at 160 kB/s.

Just incredible. Just incredible for something that has been around for
so long.

Not eating their own dog-food, I guess.

2016-04-02 Thread Boris Gjenero
I'm also having this problem copying to an external USB 3 drive, with
Nemo (Cinnamon file manager) copies around 35 MiB/s on my Q6600 CPU.
big_writes helped, but although file copying via Nemo sped up to around
60 MiB/s,  it was still CPU bound. Copying via pv < source_file >
dest_file is faster and not CPU bound, around 130 MiB/s. pv without big
writes is CPU bound at 90 MiB/s, so Nemo seems to be the main culprit in
my case.

This is in Xenial Xerus (development branch) 16.04 64-bit.

2015-02-05 Thread Edward
Had a similar problem - mount.ntfs-3g process uses up to 80% of CPU. 
Finally found the reason - large files (40GB). 
mount.ntfs has a special option to support large files -  big_writes. 
I updated my  /etc/fstab configuration file and it works now! 
CPU load variates from 0 to 45%, but not constant 80% anymore. 

Example of /etc/fstab file:

/dev/sda1 /media/USBHDD1ntfsnoatime,big_writes   00

[Bug 392204] Re: Huge CPU usage by mount.ntfs process

2013-12-11 Thread Spiralofhope
This is one of those issues where I can idly conclude that either the
developers don't eat their own dog food (use their own product), the
issue is a legal or social problem, or intentional.

I don't think my use case is particularly strange, and this problem is a
show-stopper.

On top of that, the software I'm using (the game Path of Exile) appears
to have some serious filesystem access inadequacies, and it's
recommended that people use NTFS (even on Wine).  Phooey.

So here's what I've tried:

--

Some of the earlier comments talked about perhaps-related issues being
fixed in earlier versions, and about unofficial repository versions.
I'm using Lubuntu 13.10, updated recently.  My version of ntfs isn't
hopelessly outdated.

  ntfs-3g --version

ntfs-3g 2013.1.13AR.1 external FUSE 29

I assume that any mainline fixes found a year or more before 2013.1
would have been included in what I'm using.  I really don't want to get
into compiling my own version to include anything more recent.

However, perhaps I should take compiling more seriously.  Comment 32
gives some hope, even though it's quite old.

--

comment 77 mentions

  ntfsfix -d /path/to/mountpoint

I did this (after unmounting).  There was no change.

--

comment 83 mentions using a big_writes flag, which I did via fstab:

UUID=FOO  /path/to/mountpoint  ntfs-3g  defaults,noatime,uid=1000  0  2

There was no change.  Perhaps that's to be expected.  According to
http://b.andre.pagesperso-orange.fr/changelog.html :

Version 2011.4.12AR.1 (May 18, 2011)
 defined a mount option big_writes to use application-defined write buffer 
 sizes

I wouldn't be surprised if my particular use doesn't define some more-
optimal write buffer size.

Meantime `mount.ntfs` is consuming 80-100% CPU.

I also experience this bug. mount.ntfs will consume 100% CPU (resulting
in OS freezing temporarily until whatever process completes). It's
usually triggered by untarring large tarballs, or downloading large
files to the NTFS partition, moving large files. I'm on 12.04 installed
via Wubi from Windows 7.  I've tried a variety of the suggestions
presented in the comments and on other sites. I've given up now and I'm
reinstalling Ubuntu on ext4. Good luck everyone!

[Bug 392204] Re: Huge CPU usage by mount.ntfs process

2013-03-20 Thread W. Donks
I was almost constantly getting ~95% CPU spikes from the mount.ntfs
process, according to 'top'. Disk fragmentation or big files (some files
as large as 16GB) were not causing the issue. Defragmentation of the
disk, using a Windows workstation, didn't change anything performance
wise whatsoever.

What fixed it for me was physically mounting the hard drive to a Windows
workstation and using CHKDSK. The disk wasn't damaged or anything but
apparently ntfs-3g causes 'free space marked as allocated' in both the
Master File Table (MFT) and volume bitmap. Once this is fixed the huge
spikes are gone. At least for me.

Hopefully this info can shed some light into the CPU spikes and help
some others who are having the same problem.

try enabling big_writes option for ntfs-3g.

I did it on a wubi installation and it seems to have brought a significant 
improvement, but cpu usage of ntfs-3g is still very high.
in /etc/default/grub write:
GRUB_CMDLINE_LINUX_DEFAULT=rootflags=big_writes quiet splash

clearing the dirty flag improves performance too, I think.

Wrong, Sam.
If you were to create a new really big partition for use on a mobile rack or 
an USB-disk for data exchange with the outer world, what would be your 
choice? I think, NTFS as the common denominator which is somehow understood 
by the most OSes (and, what might be even more important) appliances like 
media players (which have a linux on board, but cannot handle anything except 
of FAT/NTFS on drives attached to them).
Another case (well, my one) is a sorta legacy - NTFS disks which were moved 
from a windoze HTPC to an ubuntu NAS. Would you want me to re-format all those 
disks?

Well, sure. My issue is that I don't know nearly enough about Linux to
look into this bug myself, and have no idea what combination of factors
causes it to freeze my laptop every time I copy more than 10-100MB or so
onto my root directory (a Wubi Ubuntu 12.04 install over Windows 7). Is
it Wubi that's causing the problem (which didn't exist in my previous
11.04 install). Is it a new version of ntfs-3g that caused this bug to
occur sometimes? Is it a symptom of multiple causes across Ubuntu, or is
it a single problem that people have no interest in fixing?

Since this is the root directory doing this I doubt I can unmount as
suggested above. So I'd rather adopt the approach that causes this
problem to go away fastest rather than have my system hang every time I
want to do something other than edit text files, since it seems like
this problem won't be solved any time soon.

I have another update to my post #77.

We have had the same high-cpu load problem as described above today (Monday 
morning).
We traced it down to a Windows7 machine doing a Sunday night backup to our 
server.
Windows backup created a 190,251,249Kb (181GB) single file as part of its 
backup set.
This file causes the ntfs-3g driver to go into a spin and use 99% cpu.
Wondering if the dev team for this driver can create a file this big and see 
what happens to the driver.?
This problem is re-creatable.  Copy the file back onto the ntfs-3g enabled 
drivers and the driver goes into 99% mode again.

I struggled with this problem for many days.  I am running Ubuntu12.04
on a server and dual RAID1 setups with dual 2TB disks in each.  Disks
are formatted with NTFS and are used with samba for windows files
storage.

A week ago our system started running slow after moving some files.
Results of the 'top' utility shows 99% CPU assigned to mount.ntfs-3g.
Despite several reboots same problem.

The solution that worked for me was to umount the affected drives and
run ntfsck on them.  The utility reported the drive was dirty.  To fix
the dirty flag I run ntfsfix -d /mnt/...  and then rechecked using
ntfsck.

After the dirty flag was cleared the system is back to normal.

Hope this helps anyone else with the same issues.

using Wubi with Ubuntu 11.04 on the same machine with no problems in the
past. All have been clean installs (i.e. not upgraded from previous
versions). My version of ntfs-3g is ntfs-3g 2012.1.15AR.5 integrated
FUSE 27 (though the problem has existed for other versions after Ubuntu
11.04).

mount.ntfs appears to run whenever write-to-hard-drive is occurring.
Additionally, it blocks most applications from running (presumably as
they all eventually need to read/write to HDD), resulting in greying out
of the application window for a few minutes. It's especially problematic
when doing 1MB file operations (e.g. installing packages with apt-get).
The Windows install is barely used, so it's unlikely to be highly
fragmented.

I have tried various things mentioned in this thread to no effect (I
came unstuck with the suggestion to backport ntfs-3g as Ubuntu refused
to backport fuse/fuse-utils for some reason). I agree that it's bizarre
that this bug has persisted for so long without a fix, especially since
(in my experience) it make Wubi unuseable. I suspect that my solution
will eventually be to give up on Wubi and create a new partition for
Ubuntu, but it's frustrating that I'd have to do this when previous
versions have worked fine.

[Bug 392204] Re: Huge CPU usage by mount.ntfs process

2012-05-23 Thread Kenny Loveall
I've recently switched over from Windows to Ubuntu (11.10) and was
pulling my hair out trying to figure out why two programs we're hanging
and being very unresponsive (Filezilla and VirtualBox). Turns out that
it was that I was running them off a NTFS partition (and therefore
having ntfs-3g taking 70-100+% of CPU as others have said).  I switched
them to run off a non-NTFS partition and the transfers in FileZilla
(when they worked) jumped from about 5KB/s total to 1,600 KB/s.

Personal anecdote aside, I agree that this bug should be listed a lot
higher than medium. For people that have recently switched from Windows
and still regularly work with files on their Windows partition it is a
huge headache when everything is slow to respond. Not to mention that
it's been known since 2009 so isn't it time we fixed it? I would try
myself but I don't know enough to even know where to start, however I
hope someone else fixes it soon!

Same behaviour in Lucid updated to may 2011. VMplayer runs painfully

Seems we all will have to surrender to this fact? I just don't get why
after almost 2 years there isn't yet an official solution to the
problem. No wrapper for ntfs partitions?

I'll try the following version (taken from a previous post), but it doesn't say 
if it solved anyhow the problem:

Thanks Alexander!
Your solution improved a lot my situation. I was able to move the directory 
now. Will do some more test and see if it solves every problems or not.

Hi wolger,

Are you expecting some help ? what about providing the ntfs-3g version
you are using (type ntfs-3g --help) and the circumstances in which
this happened ? (what kind of action on what kind of file ? is it
reproducible ? how full is your ntfs partition ?)

decreased a lot and the cpu usage is 100%. this problem happens often

2010-10-28 Thread Alexander Amelkin
I've backported ntfs-3g 2010.8.8 and fuse 2.8.4 from Maverick (took them from 
http://packages.ubuntu.com)
and now it looks like the system doesn't freeze anymore, but the performance is 
vastly lower than it was with
the original Jaunty packages. I had xfer speeds like 6.5 MB/sec when moving 
from ext3 to ntfs, now I only have 2.5MB/sec. :( I yet have to check how 
Transmission behaves now on huge torrents.

For anyone interested how to backport the packages, do the following:

1. Go to packages.ubuntu.com, find the most recent package, copy the link for 
the .dsc file for it
2. Run:

dget the_copied_URL
dpkg-source -x filename.dsc
cd package_source_dir
dch -i

3. Edit the log
4. Run:

dpkg-buildpackage -rfakeroot
cd ..
sudo dpkg -i *.deb

Usually this goes smoothly enough. It may require some additional
packages, but it's quite obvious how to resolve such issues. :)

2010-10-21 Thread Steve Brown
The Tuxera FAQ says one cause of this problem is writing to sparse files
and/or fragmented volumes.

From the upstream changelog, this has recently been fixed:

STABLE Version 2010.8.8 (August 8, 2010)
* Fixed partially overwriting sparse clusters on highly fragmented volumes. 

You might try installing a more recent upstream NTFS-3g version
(2010.8.8 or 2010.10.2) and see if that helps.

Unofficial Ubuntu packages for 2010.8.8 can be found at:
https://launchpad.net/~x3lectric/+archive/team-iquik-releases/+packages

I hope we can soon get the latest version into the official Ubuntu
channels.

Can confirm this bug in Maverick. This happens when copying some sort of
big files from ext4 to ntfs , also when Transmission saves something to
ntfs partition. The GUI becomes completely unusable, it freezes till the
end of copying or finishing download in Transmission, but still I can
use console. I didn't notice such behavior of ntfs-3g in Lucid. What
kind of additional info should I post to help solve this bug?

Hi Mikko,

You did not indicate which ntfs-3g version you are using.

Anyway the performance indeed depends on the file size, and on the
fragmentation of the partition. You should try the improvement for big
and fragmented files in ntfs-3g-2010.8.8AR.5 See
http://www.tuxera.com/community/ntfs-3g-advanced/

I have the same problem on K/Ubuntu 10.04 (2GB Ram, E6750, ASUS P5B
Deluxe). I have 4 SATA hard drives, with system on the first one (ext4)
and various data on three others (ntfs). Copying 200GB of files from ie.
second to third drive makes system nearly unusable. I tried the 2010.8.8
version of ntfs-3g, I got slightly better performance, but still very
high: around 50-60% of CPU usage by monut.ntfs and about 20% by mc
during file copying from one drive to another.

2010-07-16 Thread Brian Harkness
I went to http://www.tuxera.com/community/ntfs-3g-download/ and grabbed
the rc.tgz

I made a debian package with the result, modified the version so that it
would not be upgraded and installed it.  mount.ntfs barely makes a
blip in System Monitor (ksysguard) on KDE.

One could do a 
./configure
make
sudo make install with the extracted tarball, but I like the packaging of a deb 
so it can be easily removed.  I did have to remove the associated lib file 
that accompanies ntfs-3g on ubuntu.

I didn't attach it because I am not completely familiar with the
protocol here.

Also noticed that ntfs-3g is slow at reading and writing. I used  Fedora

conky installed on my Ubuntu 9.04, but if i want to download something,
i must leave the computer until it finish downloading. Even pointer
freeze , not talking about browsing or working when copying information.
rtorrent run at 10mb/s only few seconds, just to fill up the entire
cache and then speed goes down to  1.5mb/s or 6mb/s if I don't touch
anything.

please team up with other linux distros and solve this annoying bug. All
type of operation that imply copying, reading, writing on ntfs
partitions are incredible slow and freeze the machine.

Hint... utorrent under wine don't have such a problem, maybe someone
will use wine knowledge in writing a good driver for ntfs.

2010-04-09 Thread Gary D. Huffman, II
Additional testing reveals that writing really large files must simply
be more likely to reproduce the problem, but in fact is not a
requirement.  With a NTFS partition near capacity (around 4 GB
remaining), I was able to reproduce the problem by writing a file that
is just under a GB to it.  When I noticed that it slowed way down
several seconds into writing the file, I aborted and freed an additional
half a GB more (giving a total of ~4.5 GB free).  I was then able to
write my file not-so-large file at normal speeds.  So it seems this may
be due to some odd fragmentation corner case.

[Bug 392204] Re: Huge CPU usage by mount.ntfs process

2010-01-17 Thread don.bor...@web.de
There may be an interrelation between ntfsg and the clock-device.
This problem occures on my notebook (ibm t41p) with the boot-option: clock=pit

2010-01-07 Thread solarsd
I'm also affected by this bug. When copying from or to a ntfs partition
the transfer speed starts normally but then falls down to a halt... Then
I get 100% CPU usage, 0.2% mem usage and the interesting part is that
using iotop I get only 20 K/s disk write activity in total, all due to
mount.ntfs process. That's happening on Ubuntu Karmic, kernel
2.6.31-17-generic using ntfs-3g version 1:2009.4.4-1ubuntu4. I wonder if
someone is looking into this as it is a real nasty issue...

I'm copying a 8 GB file from an Ext4 partition to an NTFS USB drive and
CPU load is 80%. The transfer rate is 7 MB/s.

This is Ubuntu Karmic.

I am experiencing same problem. Downloading a 40GB sized torrent with
transmission results in random transmission lock-ups and one core at 90%
of usage because of mount.ntfs.

I have the same proble here.

Also it seems that https://bugs.launchpad.net/ubuntu/+source/ntfs-
3g/+bug/395892 is a duplicate of this bug.

Sometimes my hard disk begins to work very hard and my CPU is used with
100 % by mount-ntfs. Even if I don't work with a NTFS partition at all
(and I don't have installed Tracker). Usually it happens a short time
after boot and takes few minutes.

2009-11-21 Thread miniwill
All the problems above, i had its too. With transmission, same thing, he freeze 
after downloading few gb of data. I also try to copy 8gb on my ntfs partition 
but the download rate decreasing from 10Mo/s to 190Ko/s. So it's not thinkable 
to wait, i return on windows to make the copy. 
I have used ubuntu for several years and I never had this problem before. 

I also have an other problem. When I open evince(pdf) the pc freeze and
I'm obliged tu press the power button to restart.

I think, i'm going to come back to Jaunty.

[Bug 392204] Re: Huge CPU usage by mount.ntfs process

2009-11-16 Thread Huygens
Here is another scenario which ends up with the same problem.
Downloading using Transmission a DVD ISO of CentOS and storing the downloaded 
file to an NTFS drive (either internal or via USB).
After a while, the CPU load is so high that Transmission does not download any 
more, it just waits (freeze mode-like) for the ntfs-3g to do something (high 
CPU load) and thus the download is kind of stalled... So, as of now, I have 
downloaded about half (1.7GB) of the DVD ISO, and when I launch Transmission it 
is just consuming CPU power (and electricity power) for basically nothing 
significant.

This is a bit frustrating as I do not have the required space on my
Linux partition to be able to download the DVD ISO...

Note: with Jaunty, the CPU usage was also remarkably high, however I had
managed to download the DVD ISO of the previous CentOS release.

I have just uploaded a version of ntfs-3g in to my PPA linked against
its own internal FUSE. Could you please try installing this package and
tell me if you still see the high CPU usage?

My PPA (and instructions for installing packages from it) can be found
here: https://edge.launchpad.net/~chrisccoulson/+archive/ppa
