I use multipath on RHEL 5.5 with RHCS clusters. The "multipath -l" should show you if your paths are available.

Problem is my fibre attached qdisk is dm-multipathed yet when I issue "mkqdisk -L" I don't see the /dev/mapper/mpath... but LUNs seen from individual fibre paths. In addition when I unplug cable (path B) for /dev/sdh1 (same as /dev/dm-13), that node gets fenced out. # mkqdisk -L mkqdisk v0.5.2 /dev/sdd1: Magic: eb7a62c2 Label: san_qdisk Created: Mon Aug 2 13:19:09 2010 Host: host1 Kernel Sector Size: 512 Recorded Sector Size: 512 /dev/sdh1: Magic: eb7a62c2 Label: san_qdisk Created: Mon Aug 2 13:19:09 2010 Host: host1 Kernel Sector Size: 512 Recorded Sector Size: 512 /dev/dm-13: Magic: eb7a62c2 Label: san_qdisk Created: Mon Aug 2 13:19:09 2010 Host: host1 Kernel Sector Size: 512 Recorded Sector Size: 512 Has anybody got dm-multipath working for qdisk on RHEL 4.8 cluster? -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
