4.2.2. 根​​​​​​​据​​​​​​​设​​​​​​​备​​​​​​​名​​​​​​​称​​​​​​​将​​​​​​​设​​​​​​​备​​​​​​​列​​​​​​​入​​​​​​​黑​​​​​​​名​​​​​​​单​​​​​​​

您​​​​​​​可​​​​​​​以​​​​​​​根​​​​​​​据​​​​​​​设​​​​​​​备​​​​​​​名​​​​​​​称​​​​​​​将​​​​​​​设​​​​​​​备​​​​​​​类​​​​​​​型​​​​​​​列​​​​​​​入​​​​​​​黑​​​​​​​名​​​​​​​单​​​​​​​，以​​​​​​​便​​​​​​​在​​​​​​​配​​​​​​​置​​​​​​​文​​​​​​​件​​​​​​​ blacklist 部​​​​​​​分​​​​​​​的​​​​​​​ devnode 条​​​​​​​目​​​​​​​中​​​​​​​指​​​​​​​定​​​​​​​不​​​​​​​要​​​​​​​将​​​​​​​它​​​​​​​们​​​​​​​分​​​​​​​组​​​​​​​到​​​​​​​多​​​​​​​路​​​​​​​径​​​​​​​设​​​​​​​备​​​​​​​中​​​​​​​。​​​​​​​

以​​​​​​​下​​​​​​​示​​​​​​​例​​​​​​​显​​​​​​​示​​​​​​​了​​​​​​​配​​​​​​​置​​​​​​​文​​​​​​​件​​​​​​​中​​​​​​​可​​​​​​​将​​​​​​​所​​​​​​​有​​​​​​​ SCSI 设​​​​​​​备​​​​​​​列​​​​​​​入​​​​​​​黑​​​​​​​名​​​​​​​单​​​​​​​的​​​​​​​行​​​​​​​，因​​​​​​​为​​​​​​​它​​​​​​​的​​​​​​​黑​​​​​​​名​​​​​​​单​​​​​​​中​​​​​​​有​​​​​​​ sd* 设​​​​​​​备​​​​​​​。​​​​​​​

blacklist {
       devnode "^sd[a-z]"
}

blacklist {
       devnode "^sd[a-z]"
}

您​​​​​​​可​​​​​​​以​​​​​​​使​​​​​​​用​​​​​​​配​​​​​​​置​​​​​​​文​​​​​​​件​​​​​​​ blacklist 部​​​​​​​分​​​​​​​的​​​​​​​ devnode 条​​​​​​​目​​​​​​​指​​​​​​​定​​​​​​​要​​​​​​​列​​​​​​​入​​​​​​​黑​​​​​​​名​​​​​​​单​​​​​​​的​​​​​​​每​​​​​​​个​​​​​​​设​​​​​​​备​​​​​​​，而​​​​​​​不​​​​​​​是​​​​​​​指​​​​​​​定​​​​​​​特​​​​​​​定​​​​​​​类​​​​​​​型​​​​​​​的​​​​​​​所​​​​​​​有​​​​​​​设​​​​​​​备​​​​​​​，我​​​​​​​们​​​​​​​不​​​​​​​推​​​​​​​荐​​​​​​​使​​​​​​​用​​​​​​​后​​​​​​​一​​​​​​​种​​​​​​​情​​​​​​​况​​​​​​​。​​​​​​​除​​​​​​​非​​​​​​​根​​​​​​​据​​​​​​​ udev 规​​​​​​​则​​​​​​​的​​​​​​​静​​​​​​​态​​​​​​​映​​​​​​​射​​​​​​​，我​​​​​​​们​​​​​​​无​​​​​​​法​​​​​​​保​​​​​​​证​​​​​​​在​​​​​​​重​​​​​​​启​​​​​​​后​​​​​​​每​​​​​​​个​​​​​​​设​​​​​​​备​​​​​​​的​​​​​​​名​​​​​​​称​​​​​​​是​​​​​​​一​​​​​​​样​​​​​​​的​​​​​​​。​​​​​​​例​​​​​​​如​​​​​​​：重​​​​​​​启​​​​​​​后​​​​​​​，某​​​​​​​个​​​​​​​设​​​​​​​备​​​​​​​的​​​​​​​名​​​​​​​称​​​​​​​可​​​​​​​能​​​​​​​从​​​​​​​ /dev/sda 变​​​​​​​为​​​​​​​ /dev/sdb。​​​​​​​

By default, the following devnode entries are compiled in the default blacklist; the devices that these entires blacklist do not generally support DM-Multipath. To enable multipathing on any of these devices, you would need to specify them in the blacklist_exceptions section of the configuration file, as described in 第 4.2.4 节 “黑​​​​​​​名​​​​​​​单​​​​​​​之​​​​​​​外​​​​​​​的​​​​​​​设​​​​​​​备​​​​​​​”.

blacklist {
       devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"
       devnode "^hd[a-z]"
}

blacklist {
       devnode "^(ram|raw|loop|fd|md|dm-|sr|scd|st)[0-9]*"
       devnode "^hd[a-z]"
}
