[Linux-cluster] Cluster Failover Failed

[dOminic]

Hi Balaji,

Yes, the reported message is harmless ... However, you can try following

1) I would suggest you to set the filter setting in lvm.conf to properly
scan your mpath* devices and local disks.
2) Enable blacklist section in multipath.conf  eg:

blacklist {
       devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"
       devnode "^hd[a-z]"
}

# multipath -v2

Observe the box. Check whether that helps ...


Regards,
