>> It looks like the quorumd max_error_cycles parameter it not taken into account.

>> All 3 cluster nodes have the following cqdisk configuration:
>> <quorumd device="/dev/iscsi/storage.quorum" interval="1"
>> log_facility="local5" log_level="7" tko="10" votes="1"
>> When I block access from the 3 nodes to the target server (iptables

>> server), I see the Quorum disk go offline but qdisk never gets stopped
