[Pacemaker] Cluster Volume Group is stuck

[Karl Rößmann]

Hi David,


startup-fencing is true
stonith is enabled
stonith-timeout is 60s
stonith-action is reboot

We have a Fibre Channel SAN with multipath driver as common device
for the Volume Groups.

I have SBD Stonith
--------------- This is the SBD Setting: --------------------------

multix244:~ # sbd -d  
/dev/disk/by-id/scsi-3600a0b8000420d5a00001cf14dc3a9a2-part1 dump
Header version     : 2
Number of slots    : 255
Sector size        : 512
Timeout (watchdog) : 60
Timeout (allocate) : 2
Timeout (loop)     : 1
Timeout (msgwait)  : 120

on a similar cluster with iSCSI device and no multipath driver
there is no problem.
