Hi again, I have another question for which I don't find any answer from documentation/man and on the net. I want to display the algorithm used by a multipath device (the "policy" as seen in multipath -ll). When doing a "show wildcards" in the multipathd shell, I can see there are wildcards for the "pathgroup" (last block): multipathd> show wildcards multipath format wildcards: %n name %w uuid %d sysfs %F failback %Q queueing %N paths %r write_prot %t dm-st %S size %f features %h hwhandler %A action %0 path_faults %1 switch_grp %2 map_loads %3 total_q_time %4 q_timeouts %s vend/prod/rev path format wildcards: %w uuid %i hcil %d dev %D dev_t %t dm_st %o dev_st %T chk_st %s vend/prod/rev %c checker %C next_check %p pri %S size pathgroup format wildcards: %s selector %p pri %t dm_st But a "help" command doesn't document any "pathgroup" target for a show command : multipathd> help multipath-tools v0.4.9 (04/04, 2009) CLI commands reference: list|show paths list|show paths format $format list|show status list|show daemon list|show maps|multipaths list|show maps|multipaths status list|show maps|multipaths stats list|show maps|multipaths format $format list|show maps|multipaths topology list|show topology list|show map|multipath $map topology list|show config list|show blacklist list|show devices list|show wildcards add path $path remove|del path $path add map|multipath $map remove|del map|multipath $map switch|switchgroup map|multipath $map group $group reconfigure suspend map|multipath $map resume map|multipath $map resize map|multipath $map disablequeueing map|multipath $map restorequeueing map|multipath $map disablequeueing maps|multipaths restorequeueing maps|multipaths reinstate path $path fail path $path paths count forcequeueing daemon restorequeueing daemon quit|exit map|multipath $map getprstatus map|multipath $map setprstatus map|multipath $map unsetprstatus So I don't know from multipathd -k how to get the policy of a multipath device. It would be really great if someone could explain it ;) Thanks a lot, -- Nicolas MICHEL -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
