cp/mv broken in OpenVZ kernel: Please pull important fix

SRU Justification:

Impact: cp and mv fail in most cases, rendering the openvz flavour unusable.

Fix Description: make stat and fstat agree on (st_dev, st_ino) in VE. This patch affects only the openvz kernel.

Patch: http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-hardy.git;a=commit;h=093579b35541f6a3a3ecfebf6f224ff336846d56

TEST CASE: See discussion in http://forum.openvz.org/index.php?t=msg&th=5912

http://kernel.ubuntu.com/git?p=ubuntu/ubuntu-hardy.git;a=commit;h=093579b35541f6a3a3ecfebf6f224ff336846d56

Is there a dpkg we can download to try this?

I built a test kernel using the following commands (last line is the kernel it actually built for you, 17.32 contained the fix for this bug):

sudo aptitude install linux-kernel-devel fakeroot build-essential ubuntu-dev-tools git

git-clone git://kernel.ubuntu.com/ubuntu/ubuntu-hardy.git openvz

cd openvz
AUTOBUILD=1 NOEXTRAS=1 DEB_BUILD_OPTIONS=parallel=4 fakeroot debian/rules custom-binary-openvz
cd ..
sudo gdebi linux-image-2.6.24-17-openvz_2.6.24-17.32_amd64.deb

Thanks but unfortunately I can't install gcc etc on this box. No matter, I will wait.

Hi Jergen,

You don't need to compile the package on the same box where you will use it. Do as Bastian said on a temporary box and transfer the linux-image-2.6.24-17-openvz_2.6.24-17.32_amd64.deb package where you'd like to use it and install it with dpkg -i linux-image-2.6.24-17-openvz_2.6.24-17.32_amd64.deb.

Reboot, install vzctl and you have a fully functioning openvz system.

Cheers,
Karoly

I almost forgot that the installation instructions are updated on the OpenVZ Ubuntu Community Documentation page: https://help.ubuntu.com/community/OpenVZ#head-54cf69fe78967a48df8215528bf78747e49e4c42

Read it and you'll see that there is a temporary repository from where you could fetch & install the kernel.

Cheers,
Karoly

Thanks.

Unfortunately that kernel toasted my server. Because of an ubuntu installer bug, I use lilo instead of grub as my bootloader.
The image in PPA here does not work with lilo - it's too big.

I use the compbrain PPA for these kernels. I left the Compbrain PPA kernels for 2.6.24-18 dist kernels and discovered this bug. This of course stops the network up/down scripts from functioning properly as well.

Sample Error:
    root@bip:/# cp /etc/hosts /etc/hosts2
    cp: skipping file `/etc/hosts', as it was replaced while being copied

Running:
    linux-image-2.6.24-18-openvz (2.6.24-18.32) as of today.

Reverting back to PPA kernels hoping nothing awkward just happened to my VZ's

Just curious, are there OpenVZ tests used before releasing kernels to the masses?

Hi,

I have the same problem with linux-image-2.6.24-18-openvz.
It fails on copy with "skipping file as it was replaced while being copied"

Went back to linux-image-2.6.24-17-openvz and it works.

Accepted into -proposed, please test and give feedback here

Martin, where can I find "-proposed" ?

Mik:

see http://blog.omma.net/?p=11 for reference on how to get proposed updates and enjoy your new (hopefully) working kernel afterwards

Thx Bastian.
The linux-image-2.6.24-19-openvz (2.6.24-19.33) from hardy-proposed repo working for me.

Thanks
The linux-image-2.6.24-19-openvz also worked for me.

linux-image-2.6.24-19-openvz works for me too. Thanks.

Works for me, too. Changing tag to "verification-done".

Works here too.

Copied to hardy-updates.

is this fix present in intrepid?

Custom binaries (openvz, xen, rt) are no longer present or supported in Intrepid.

marking as invalid since the openvz kernel flavor is not available in intrepid.
