description |
On the Precise default kernel, it is possible by executing zcat on a large file for an unprivileged user to disrupt I/O sufficiently that it causes serious disruption.
Serious disruption means (e.g.) a single MySQL update hangs for over 120 seconds on the default scheduler (cfq), and between 1 and 11 seconds on the deadline scheduler.
This is reproducible on 2 sets of hardware using:
root@extility-qa-test:~# uname -a
Linux extility-qa-test 3.2.0-29-generic #46-Ubuntu SMP Fri Jul 27 17:03:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
linux-image-3.2.0-29-generic 3.2.0-29.46
root@extility-qa-test:~# cat /proc/sys/vm/dirty_ratio
20
root@extility-qa-test:~# cat /proc/sys/vm/dirty_background_ratio
10
No such problems occur on Lucid OS running the Oneiric Backports kernel.
root@management-dev2:~# uname -a
Linux management-dev2 3.0.0-15-server #26~lucid1-Ubuntu SMP Wed Jan 25 15:55:45 UTC 2012 x86_64 GNU/Linux
linux-image-3.0.0-15-server 3.0.0-15.26~lucid1
In order to replicate, download (e.g.) this gzipped Lucid image (note this is not the OS we are running, this is just an example of the a file that causes the problem):
http://repo.flexiant.com/images/public/kvm/ubuntu10.04.img.gz
and as un unprivileged user, on a default, untuned Precise install, do
zcat ubuntu10.04.img.gz > test
Now in another window execute any trivial mysql update on any table. Note that this can take a hugely long time.
"show full processlist" in mysql console will show the time taken executing the command.
In kernel logs (with cfq) we see e.g.:
Oct 8 14:57:02 extility-qa-test kernel: [ 3840.268048] INFO: task mysqld:1358 blocked for more than 120 seconds.
