[Bug 1214085] [NEW] LXC + BTRFS: creating many containers simultaneously can cause system corruption
Public bug reported:
Using lxc with a btrfs filesystem can lead to system corruption and
containers which are unable to boot when many containers are created and
started simultaneously.
Packages involved:
- btrfs-tools
- ubuntu-lxc/daily from http://ppa.launchpad.net/ubuntu-lxc/daily/ubuntu
`lsb_release -rd`:
ubuntu@ip-10-91-30-131:~$ lsb_release -rd
Description: Ubuntu 12.04.2 LTS
Release: 12.04
Here is the relevant discussion thread: http://www.mail-archive.com/lxc-
users@xxxxxxxxxxxxxxxxxxxxx/msg05472.html
And here is a key excerpt regarding reproducing the problem:
The general system state is something like:
N containers already running happily
Launch N+ more containers in rapid succession (in parallell, not serially).
Here is a test script which closely reflects what my application is
actually doing. It slowly launches 10 containers and then uses "&" to
rapidly fork an additional 10 clone/start operations. I have it doing 2
cycles of this, and running the script many times (2-6 times) eventually
triggers the problem.
test.sh:
#!/usr/bin/env bash
prefix=$1
test -z "${prefix}" && echo 'error: missing required parameter: prefix'
1>&2 && exit 1
path=/mnt
sudo lxc-destroy -n c1 2>/dev/null
sudo lxc-create -t ubuntu -B btrfs -n c1
for i in `seq 1 10`; do
sudo lxc-clone -s -B btrfs -P $path -o c1 -n $prefix$i
sudo lxc-start -d -n $prefix$i
done
for i in `seq 11 20`; do
echo $(sudo lxc-clone -s -B btrfs -P $path -o c1 -n $prefix$i; sudo lxc-start -d -n $prefix$i) &
done
sleep 10
# Create even more.
for i in `seq 21 30`; do
sudo lxc-clone -s -B btrfs -P $path -o c1 -n $prefix$i
sudo lxc-start -d -n $prefix$i
done
for i in `seq 31 40`; do
echo $(sudo lxc-clone -s -B btrfs -P $path -o c1 -n $prefix$i; sudo lxc-start -d -n $prefix$i) &
done
stop.sh:
#!/usr/bin/env bash
prefix=$1
test -z "${prefix}" && echo 'error: missing required parameter: prefix'
1>&2 && exit 1
sudo lxc-destroy -n c1;
for i in `seq 1 40`; do
echo $(sudo lxc-stop -k -n $prefix$i; sudo lxc-destroy -n $prefix$i) &
done
bash ./test.sh x
bash ./test.sh y
bash ./test.sh z
If it doesn't manifest at first, try starting/stopping/destroying
varying quantities of containers for several cycles. Eventually I
consistently end up not ever getting ip addresses or being able to even
successfully start a container:
