http://bugzilla.kernel.org/show_bug.cgi?id=11646 ------- Comment #21 from grin@xxxxxxx 2009-02-27 08:17 ------- #20, enlighten me in the internals, please. Can multipathd actually _cause_ driver timeouts? As much as I understood directio checker does nothing more than reads first and last sector of the device by direct IO (O_DIRECT) calls, and if that fails it fires an uevent towards userspace to handle the situation. Can it do anything "below", like the qla driver, or the scsi device itself? I tried 'tur' checker in the past with mixed results, and I'm not sure it meant the path was really down that much or the checker failed, but directio seemed the most generic. I thought it's the other way around, eg. qla timoeuts which makes multipathd cry. -- Configure bugmail: http://bugzilla.kernel.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
