[Bug 1296681] Re: failed to change apparmor profile to lxc-container-default

2014-06-15 Thread Matt Rae
*** This bug is a duplicate of bug 1296459 ***
https://bugs.launchpad.net/bugs/1296459

I seem to be seeing this issue as well. I'm not sure if its the
duplicate issue.

The profile config file name is lxc-default-with-mounting yet the
actual profile name appears to be changed to lxc-container-default-
with-mounting causing confusion.

/etc/apparmor.d/lxc/lxc-default-with-mounting

Inside that file the profile name is lxc-container-default-with-
mounting. I presume that at some point  the profile naming convention
was changed from lxc-default to lxc-container-default but the file
name didn't get changed to match the convention.

This is confusing because if I configure the apparmor profile in the lxc
config based on the config filename I'll get an error:

lxc.aa_profile = lxc-default-with-mounting

error:

lxc-start: No such file or directory - failed to change apparmor profile
to lxc-default-with-mounting

using the actual profile name from inside the file lxc.aa_profile =
lxc-container-default-with-mounting solves the problem.

I think a solution to the multiple names confusion would be to rename:
/etc/apparmor.d/lxc/lxc-default-with-mounting
to
/etc/apparmor.d/lxc/lxc-container-default-with-mounting

[Bug 1099115] Re: Can't change brightness while screen is locked

2014-04-29 Thread Matt Rae
Is this a usability issue?

I'd like to be able to turn off the backlight to listen to music in the
dark. When I come back to turn the brightness up, the screen is locked
and the brightness control doesn't work. I have to blindly enter in my
password (yikes?). If I didn't realize that the screen was locked a
reset would be the only fix. That doesn't seem very user friendly.

[Bug 1179610] Re: poor performance of resize2fs on 12.04

2013-09-30 Thread Matt Rae
Thanks Scott, yeah we tried the raring image and saw a 200x improvement.
We booted a precise and raring image to compare and precise took 200sec
for the resize while raring took 1.2sec. We're doing all of our testing
with a raring instance right now.

I don't have a urgent need for precise but it is quite a bit slower for
the initial boot.

noting I'm using the current precise cloud image:

I'll have to confirm the resize2fs version. If there is any other
details that would be helpful let me know.

I'm seeing slow resizefs from cloud-init.log when booting from volume,
where the volume is 100G ceph rbd. I'm seeing high IO on ceph during
this time even though I'm booting one instance at a time with a 20 disk
ceph cluster. Is resize2fs an expensive operation?

[Bug 1069570] Re: 1 MAC Address, two IPs - DNS is out of sync with DHCP leases databases

2013-09-25 Thread Matt Rae
I see for precise-proposed, the patch is to add a 30 second lease for
pxe agents. This is resulting the lease during pxe being added to the
leases file with a 30 second expiration as expected, but the expiration
is not being honored.

We are seeing machines given the ip from the 30 second lease long after
it had expired.

It appears dhcpd is not respecting the 30 second lease and still giving
the wrong ip to nodes.

Example:

Below are the leases for a machine that came up with the wrong ip. The
lease for 172.21.66.24 is supposed to be for 30 seconds, but it appears
it was not being respected, since the node would come up with .24 after
rebooting long after the lease should be expired.

  dynamic;
  hardware ethernet 52:54:00:e3:1d:47;

[Bug 1023069] Re: Packages was corrupt

2013-01-17 Thread Matt Rae
Expected Behavior:

Installer continues without warning about a corrupt Packages file.


Behavior actually encountered:

During install a red warning screen appears with the following message:

[!!] Install the base system
Debootstrap warning
Warning:
http://192.168.0.1/ubuntu/dists/lucid/restricted/binary-amd64/Packages was 
corrupt
Go Back Continue

Pressing enter to continue allows the installer to continue installing.


Reproduction steps:


To reproduce this bug, create a pxe boot server and apt repo.

Build a vm with 2 nics for the server.

Configure the second nic (eth1) for a private network we will use to
test netbooting the installer on a separate vm.

Install Ubuntu with 10.04.04 amd64 alternate install cd for our server:
http://releases.ubuntu.com/lucid/ubuntu-10.04.4-alternate-amd64.iso

Boot Ubuntu and add the following lines to /etc/network/interfaces to
configure eth1 with a static address replacing gateway with your
internet gateway:

auto eth1
iface eth1 inet static
  address 192.168.0.1

Reboot Ubuntu so that the second nic is configured at boot.

Attach/insert the Ubuntu 10.04.04 cd to the vm so we can use it later.

Install dnsmasq for dhcp and tftp servers:

apt-get install dnsmasq

Edit /etc/dnsmasq.conf adding the following lines to enable dhcp and
tftp:

dhcp-boot=pxelinux.0
dhcp-range=192.168.0.50,192.168.0.150,12h
enable-tftp
interface=eth1

Restart dnsmasq:

service dnsmasq restart

Mount the Ubuntu 10.04 cd’s install/tftpboot directory under
/var/lib/tftpboot:

mkdir /var/lib/tftpboot
mount --bind /media/Ubuntu\ 10.04.4\ LTS\ amd64/install/netboot/ 
/var/lib/tftpboot

Create pxe boot config file /root/mydefault containing the following
lines:

TIMEOUT 50
PROMPT 1
default netboot
 nabel netboot
 kernel ubuntu-installer/amd64/linux
 append vga=normal local=en_US setup/layoutcode=en_US 
console-setup/layoutcode=us initrd=ubuntu-installer/amd64/initrd.gz 
ks=http://192.168.0.1/ks.cfg

Note above, ks=http://192.168.0.1/ks.cfg points to the kickstart file.

Mount mydefault under /var/lib/tftpboot:

mount --bind /root/mydefault /var/lib/tftpboot/pxelinux.cfg/default

To set up apt repo, mount the Ubuntu cd under /var/www/ubuntu:

mkdir -p /var/www/ubuntu
mount --bind /media/Ubuntu\ 10.04.4\ LTS\ amd64/ /var/www/ubuntu

Install apache to serve packages via http for apt repo:

apt-get install apache2

[Bug 1014872] Re: no debug symbols for mysql-server

2012-10-22 Thread Matt Rae
If there are at least any thoughts that could help me continue debugging
this problem that would be helpful.

I'd like to submit a full backtrace to report a crash in Mysql. If I can
build the debug symbols correctly without messing with the packaging, I
can go that route as well.

[Bug 1014872] Re: no debug symbols for mysql-server

2012-07-05 Thread Matt Rae
Any idea who might be able to help guide me with this?

I haven't had luck yet compiling mysql-server with debug symbols.
Although I've added -DWITH_DEBUG=1 to debian/rules build, when dh_strip
runs it says that the packages have already been stripped. ddebs are not
being built in /var/cache/pbuilder/result/. Based on that I think
-DWITH_DEBUG=1 isn't taking effect. I confirmed -DWITH_DEBUG=1 is the
correct option (http://dev.mysql.com/doc/refman//5.5/en/compiling-for-
debugging.html). Any thoughts?

Here's the steps I'm taking:

# apt-get source mysql-server

Add -DWITH_DEBUG=1 to debian/rules

# grep -C2 DEBUG mysql-5.5-5.5.24/debian/rules
-DWITH_ARCHIVE_STORAGE_ENGINE=ON \
-DWITH_BLACKHOLE_STORAGE_ENGINE=ON \
-DWITH_DEBUG=1 \
-DWITH_FEDERATED_STORAGE_ENGINE=ON \
-DWITH_EXTRA_CHARSETS=all ..'

[Bug 1014872] [NEW] no debug symbols for mysql-server

2012-06-18 Thread Matt Rae
Public bug reported:

Hi there, no debug symbols packages are available for mysql-server.
Neither a mysql-server-dbg package is available or mysql-server-dbgsym
from ddebs.ubuntu.com.

According to xnox in #ubuntu-devel:

12:32  xnox there was a bug about it or something somewhere
12:32  xnox mattrae: basically the buildsystem unconditionally strips them /
builds without them.

I wasn't able to find a bug, so I created this one to track the problem.

I've attempted 2 methods that work with other packages but not mysql.

steps from here http://askubuntu.com/questions/41610/how-do-i-rebuild-a
-package-to-include-debugging-information:

apt-get install devscripts fakeroot
apt-get build-dep mysql-server
export DEB_BUILD_OPTIONS=debug nostrip noopt
fakeroot apt-get source -b mysql-server

and with pbuilder, building packages after installing pkg-create-dbgsym
in the pbuilder chroot:

apt-get source mysql-server
pbuilder create --debootstrapopts --variant=buildd
pbuilder --update --extrapackages pkg-create-dbgsym
pbuilder build mysql-5.5_5.5.24-0ubuntu0.12.04.1.dsc

[Bug 844369] Re: Backup to Ubuntu One failed (SSLError: The read operation timed out)

2012-04-23 Thread Matt Rae
Hi, this problem is continuing to exhibit itself as of 4/22/2012.

Reviewing this bug, the problem doesn't appear to be pinpointed quite
yet. So far U1 servers have been restarted, the upstream bug linked to
in #14 includes a patch to increase the timeout, and #15 suggests a bug
when the folder synced is actually a symlink. Can anyone confirm?

Is anybody else continuing to see this? Should there be a cleaner error
message when the timeout occurs?

2012-03-09 Thread Matt Rae
Public bug reported:

Linux clients that use ldap authentication with nslcd and a long

reproduction steps:

modify entry for 127.0.1.1 in /etc/hosts so the example.com dc is used by slapd
EX:
x.x.x.x   server1
change to:
x.x.x.x   server1.example.com server1

apt-get install nslcd # set search base dc=example,dc=com. then select all 
for services use ldap lookups when configuring libnss-ldapd.
apt-get install slapd
dpkg-reconfigure slapd # dns name example.com
apt-get install migrationtools

turn on ldap authentication using pam-auth-update

stop nslcd and slapd. We'll start them in debug mode
