[Pacemaker] Cluster crash

[Hugo Deprez]

Hello,

does anyone have an idea ?

it seems that at 13:06:38 resources et started on slave member.
But then there is something wrong on server01 :

Feb  8 13:06:39 server01 pengine: [19469]: info: determine_online_status:
Node server01 is online
Feb  8 13:06:39 server01 pengine: [19469]: notice: unpack_rsc_op: Operation
apache2_monitor_0 found resource apache2 active on server01
Feb  8 13:06:39 server01 pengine: [19469]: notice: group_print:  Resource
Group: supervision-grp
Feb  8 13:06:39 server01 pengine: [19469]: notice: native_print:
fs-data    (ocf::heartbeat:Filesystem):    Stopped
Feb  8 13:06:39 server01 pengine: [19469]: notice: native_print:
nagios-ip    (ocf::heartbeat:IPaddr2):    Stopped
Feb  8 13:06:39 server01 pengine: [19469]: notice: native_print:
apache2    (ocf::heartbeat:apache):    Started server01
Feb  8 13:06:39 server01 pengine: [19469]: notice: native_print:
nagios    (lsb:nagios3):    Stopped


But I don't understand what fails if this is DRBD or apache2 causes the
issue.

Any idea ?
