HAST and CARP

[hiroshi at soupacific.com]

HI folks !

I finished to run HAST with CARP and ifstated.

Question I haove now.

SERVERA is master for CARP and HAST
then boot SERVERB

ServerB is using CARP and ifstated.
First CARP state is INIT then BACKUP
Similar to ucarp's method, vip-down.sh is called.
vip-down.sh calls carp_down.sh

Inside is almost same to ucarp_down.sh except delete ucarp staff.

if I do not put hastctl create xxxx, then hastd refuse connection and 
message says
Split-brain detected secondary !


I put debug call but I can not figure out what kind value is correct.

	} else if (res->hr_secondary_localcnt > res->hr_primary_remotecnt &&
	     res->hr_primary_localcnt > res->hr_secondary_remotecnt) {
		/*
		 * Not good, we have split-brain condition.
		 */
//hiroshi debug
pjdlog_error("secondary_remotecnt %lu, primary_remotecnt %lu", 
res->hr_secondary_remotecnt, res->hr_primary_remotecnt);
pjdlog_error("secondary_localcnt %lu, primary_localcnt %lu", 
res->hr_secondary_localcnt, res->hr_primary_localcnt);
		pjdlog_error("Split-brain detected, exiting.");
		nv_add_string(nvout, "Split-brain condition!", "errmsg");
		free(map);
		map = NULL;
		mapsize = 0;
	} else /* if (res->hr_secondary_localcnt < res->hr_primary_remotecnt ||


hastctl status return perfect as secondary.
Only looks like connection error.

When using ucarp with debug
Booting as secondary

vip-up.sh
then
vip-down.sh

But CARP,
only calls vip-dwon.sh directly.

Once I put hastctl create xxx before hastctl role secondary. Things 
works fine.

Do I need hastctl create xxx or split-brain secondary is wrong?

My complete files are here.

Anybody to try HAST with CARP, please try! but any mistake I made, All 
risk is your own please.

My HAST, CARP and ifstated works fine!
