[ruslan usifov]

hello

I run pacemaker on ubuntu (Ubuntu 10.04.1 LTS) with corosync, i installed it
from apt, and my pacemaker version is:

root at storage0:/var/log# dpkg -l | grep 'pacemaker'
ii  pacemaker                           1.0.8+hg15494-2ubuntu2          HA
cluster resource manager


and have follow problem with pacemaker, with follow configration:
root at storage0:/var/log# crm configure show
node storage0
node storage1

        params drbd_resource="web" \
        op monitor interval="10s" timeout="60s"

When i shutdown node storage1, node storage0 doesn't  accept Master drbd
role, so output from crm_mon -1 lokks like this:
============
Last updated: Mon Dec  6 15:04:18 2010

============

Online: [ storage0 ]
OFFLINE: [ storage1 ]

     Slaves: [ storage0 ]
     Stopped: [ drbd_web:1 ]

Started storage0 FAILED

Failed actions:
    iscsi_web_target_lun1_start_0 (node=storage0, call=91, rc=1,
status=complete): unknown error


and when try to promote node got folow error:
crm(live)resource# promote ms_drbd_web
Error performing operation: Remote node did not respond


and periodicaly in /var/log/messages, i see folow error:
Dec  6 14:49:35 storage0 kernel: [ 5048.618562] pengine[8584]: segfault at 8

ip b7751094 sp bfe1ccb0 error 4 in libpengine.so.3.0.0[b7746000+32000]



Why pacemacker doesn't switch role of live node to master? And why segfault
happens?
Please help
