| Fixed In Version | device-mapper-multipath-0.4.9-94.el6 | |||
| Doc Text | Cause: Multipathd automatically reinstated Implicit ALUA devices in the GHOST state, which were not usable. Consequence: Multipath would continuously retry unusable devices, if they were the only ones present, instead of fail IO Fix: Multipathd no longer reinstates unusable Implicit ALUA ghost paths. Result: Multipath no longer continuously reties IO when only unusable Implicit ALUA paths are available. |

Result: Multipath no longer continuously reties IO when only unusable Implicit ALUA paths are available. | *device-mapper-multipath* no longer continuously retries I/O when only unusable Implicit ALUA paths are available Previously, the *multipathd* service automatically reinstated unusable Implicit ALUA devices in the GHOST state. As a consequence, multipath continuously retried unusable devices, if they were the only ones present, instead of failing I/O. With this update, *multipathd* no longer reinstates unusable Implicit ALUA ghost paths. As a result, *multipathd* fails I/O as expected in the described situation. |

As a result, *multipathd* fails I/O as expected in the described situation. | *device-mapper-multipath* now supports the `max_sectors_kb` configuration parameter With this update, *device-mapper-multipath* provides a new `max_sectors_kb` parameter in the defaults, devices, and multipaths sections of the `multipath.conf` configuration file. This parameter allows you to set the 'max_sectors_kb` device queue parameter to the specified value on all underlying paths of a multipath device before the multipath device is first activated. When a multipath device is created, the device inherits the `max_sectors_kb` value from the path devices. Manually raising this value for the multipath device or lowering this value for the path devices can cause multipath to create I/O operations larger than the path devices allow. Using the `max_sectors_kb` `multipath.conf` parameter is an easy way to set these values before a multipath device is created on top of the path devices, and prevent invalid-sized I/O operations from being passed down. |
