Dear Maintainer,
*** Reporter, please consider answering these questions, where appropriate ***
* What led up to the situation?
wheezy to jessie upgrade
* What exactly did you do (or not do) that was effective (or
ineffective)?
learn about systemd
* What was the outcome of this action?
systemd's extream parallelism delays the startup of mysql server
beyound that expected previosuly
* What outcome did you expect instead?
for mysql to wait until started, or to report a proper error code.
*** End of the template - remove these template lines ***
The patch which works for here is to extend the wait for mysql start to 90
seconds as follows:
/etc/init.d/mysql from line 111:-
# 6s was reported in #352070 to be too few when using ndbcluster
# 14s was reported in #736452 to be too few with large installs
# 30 is far to short in the jessie systemd rush Berni 3/1/15
for i in $(seq 1 90); do
sleep 1
if mysqld_status check_alive nowarn ; then break; fi
log_progress_msg "."
done
Perhap instead there should be some serialisation introduced into the systemd
startup to maximise the resources available to a critical service such as a
database startup. If I find out how I will follow up. Meantime please feel
free to close the bug.
