How dose angel do in MMM2.0.9? need special configure for it ?

[Tomas]

Dear experts,

I am working on a 2.0.9 setting up right now, I am quite curious what
does angel do in this version?

Do we still need a angel configure file for it? how it works? I try to
kill an agent process manually, but seems it is not restart by angel,
what should I do to configure angel ?

Thanks a lot

Yours Tomas

Hi Tomas,

theres no special configuration needed for the angel functionality in
MMM 2.x. All daemons fork at startup and the parent process keeps
looking after the child and restarts it if needed.

I think you killed the parent/angel process instead of the child.

Hi Pascal,

As I check ,there are 2 mmmd_agent running, either which is killed,
all gone.

root 25830 1 0 17:38 ? 00:00:00 perl /usr/sbin/
mmmd_agent
root 25831 25830 0 17:38 ? 00:00:00 perl /usr/sbin/
mmmd_agent

I do it several times, using kill , is that designed to act like
this ?

Thanks a lot.

Yours Tomas

Hi,

Is it necessary to have odd/even auto increments for synch to be re-established in case of write node going down?

If yes, I think this should be in the documentation for mmm configuration.

Hi Tomas,

Depends on which signal you send. SIGINT, SIGTERM and SIGQUIT will
lead to a normal shut down if sent to the child process (the one with
the higher pid in your case).

Try sending SIGSEGV, SIGKILL, SIGPIPE for example.
