However, in the message log, we so a *lot* error messages continuously passing by: Sep 12 09:04:43 quentin kernel: device-mapper: multipath emc: long trespass command will be send Sep 12 09:04:43 quentin kernel: device-mapper: multipath emc: honor reservation bit will not be set (default) Sep 12 09:04:43 quentin kernel: device-mapper: table: 253:6: multipath: invalid number of priority groups Sep 12 09:04:43 quentin kernel: device-mapper: ioctl: error adding target to table Sep 12 09:04:43 quentin multipathd: root_joel: failed in domap for addition of new path sdg Sep 12 09:04:43 quentin multipathd: root_joel: uev_add_path sleep This repeats every second. How should we interpretate these loggings? How to stop it.
