| Doc Text: |
The default values for the dev_loss_tmo, polling_intervals, fast_io_fail_tmo, no_path_retry and flush_on_last_del parameters resulted in slow path failover. The default values of these parameters have been updated in the current VDSM package as follows:
* dev_loss_tmo 30
* polling_intervals 5
* fast_io_fail_tmo 5
* no_path_retry fail
* flush_on_last_del yes
Path failover now behaves as expected.
