Part of the issue (why it takes so long) is that ecryptfs does not
support sparse files. So an operation that is fast in an unencrypted fs
is slow with ecryptfs.
$ time truncate -s 2000M file.img # ecryptfs
real 0m26.239s
user 0m0.001s
sys 0m22.984s

Sometimes it might be because of your hardware failure or overloading of
the torrent application.

You can pull down those patches, apply them, and build a kernel yourself
(something that you'd have to research and do on your own) or you'll
have to wait for your distro to release a kernel update with these
have change in kernel as you talked about some kernel change.
but still my device is hang with ecryptfs .
please help me.

change the status from Triaged to Confirmed.

Hi Brad,
Does this mean that drive encryption is no longer supported? Or, that drive
encryption is still supported and this bug will never be fixed?

This bug DOES affect lucid which is still supported. I can't see how to
mark that in Launchpad or reopen the bug. Please could someone do that?
Why would we have to open a new bug? That doesn't make any sense.

1.5 years after the initial bug report and Ubuntu guys still look aside
and still offer this as an option in the installer with no warning.

processes require a system reboot which is very annoying, this is likely
to contribute to people (including me) regarding Ubuntu LTS as unstable,
and I'm now regretting choosing to encrypt my homedir during the
installation
I can attest to this in Lucid with ecryptfs encrypted /home/user. I'm
not sure about Transmission or Vuze, but in rtorrent, there's a way to
save the machine and still have large torrent downloads; add this to
your ~/.rtorrent.rc:
split_file_size = 8G # or 4G or 3G, depending on your system
Hey JFo,
Actually, it is a kernel bug, and Tyler Hicks (the upstream maintainer)
sees the problem, but hasn't had time to fix it. Ubuntu kernels are
affected, though we're not working on it on the Ubuntu side. We're just
waiting for upstream to commit a fix.
Thanks!
Dustin

I have this problem as well, but I'm quite sure it's now just being
slow, as I waited for several hours and operations didn't finish (all
other operations on the encrypted filesystem take minutes at most, even
with 10 GiB files). It appears that this happens when the requested file
size is bigger
Under top, init with pid 0 is the one that has 100 cpu, so the second bug
isn't one.

Tyler has it on the upstream kernel side. Adding a task against

Hy!
I understand that it can take a while to create a 4 gb file, but what is
strange, that:
- I don't think that it has to take more than ten minutes (core2...@2ghz 2 gb
ram WD3200BEVT hdd 5200 rpm)
- The disk stops working after about 3-4 seconds
- with dm-crypt (what I switched to encrypt my
what I think the ext4 file system
Green is still very slow and I think it is stupid to think that besides
the stable ecryptfs that not all Czech
v ext3 and see the difference in yield figure look what happens in fedora
have many problems with ext4
is cruel to say but I would eliminate it
Hi Victor and u-foka - It looks like u-foka is correct that it occurs
when rtorrent creates and extends a file big enough for the entire
torrent download. If you're downloading something like a dvd iso, this
causes eCryptfs to encrypt 4.7 GB of zero's and write the result to the
lower filesystem.
For me, this happens on a core2duo 1,6GHz notebook, so it is not exactly
the fastest thing ever; I think the slow notebook hard drive has a say
in this too.
I don't know how LUKS works behind the scenes, but this only happens on
ecryptfs, not LUKS.
You are right, I was downloading large files,
After taking a look at the call trace during a truncate that extends a
file, eCryptfs could probably handle this in a more efficient way.
- ecryptfs_setattr
- ecryptfs_truncate
- ecryptfs_write
...
- ecryptfs_get_locked_page
- ecryptfs_readpage
- ecryptfs_read_lower_page_segment
Hy there!
I having the very same problem with an up2date jaunty ecryptfs home, and
transmission (the included version, and after first having the issue,
updated to transmissionbt ppa) as soon as transmission starts allocating
the space for the torrent data, my one of my cpu cores gets 100%

Do you get anything in dmesg? Or elsewhere in /var/log/*?
Something from the kernel, perhaps, complaining about ecryptfs?
