[Postgres-xc-developers] gtm_ctl couldn't stop gtm_standby immediately

[Tomonari K. <t.k...@gm...>]

Hi,

I found a odd behavior with gtm_standby(gtm_sby).
When the network to gtm_master is broken, gtm_ctl couldn't stop gtm_sby
even if I add an option "-m i".

I simulates the situation with iptables command.
(gtm_sby access to gtm_master via eth1)
# iptables -I INPUT -i eth1 -j DROP
# iptables -I OUTPUT -o eth1 -j DROP

And then, I start and stop immediately with these commands.
$ gtm_ctl -D <gtm_sby-PATH> -Z gtm start
$ gtm_ctl -D <gtm_sby-PATH> -Z gtm stop -m i

The last command left below message.
-------
waiting for server to shut
down............................................................... failed
gtm_ctl: server does not shut down
--------

But actually gtm_sby has stoped while the last command.

In my opinion, stopping with "-m i" should stop gtm_sby immediately.
Because vanilla-PostgreSQL do so.

Should we resolve this problem?
