possible gdb backtrace of seg fault?
not sure if I did this backtrace right...
Here is what I did to get running: 1. Patch sysfsutils with the patch located here (this solves the seg fault): http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=481015 2. multipath (or maybe libsysfs) can't find the "bus"... hack libmultipath to use "subsystem" instead. at least my paths are setup now and queuing io correctly for now: # multipath -ll mpath0 () dm-0 NETAPP,LUN [size=1.0T][features=1 queue_if_no_path][hwhandler=0] \_ round-robin 0 [prio=100][active] \_ 3:0:1:0 sdc 8:32 [active][ready] \_ 4:0:1:0 sde 8:64 [active][ready] \_ round-robin 0 [prio=20][enabled] \_ 3:0:0:0 sdb 8:16 [active][ready] \_ 4:0:0:0 sdd 8:48 [active][ready] I've put my hacked up packages here: http://shishz.fedorapeople.org/ Patch applied. Thanks. device-mapper-multipath-0.4.7-15.fc9 has been submitted as an update for Fedora 9 device-mapper-multipath-0.4.7-15.fc9 has been pushed to the Fedora 9 testing repository. If problems still persist, please make note of it in this bug report. If you want to test the update, you can install it with su -c 'yum --enablerepo=updates-testing update device-mapper-multipath'. You can provide feedback for this update here: http://admin.fedoraproject.org/updates/F9/FEDORA-2008-4375 device-mapper-multipath-0.4.7-15.fc9 has been pushed to the Fedora 9 stable repository.

yum upgrade from f8 to f9, device-mapper-multipath-0.4.7-15.fc9.i386 multipath, multipathd and multipath.static all segfault are there packages with debugging information? Paulo could you try: yum --enablerepo=updates-testing update libsysfs it looks like libsysfs-2.1.0-4.fc9 hasn't hit stable yet. If this fixes your problem could you increment karma on: https://admin.fedoraproject.org/updates/F9/FEDORA-2008-4290 Zing thanks, that did it! Will do! |
