Hi Peter, Thanks for picking this up.
Note: I ran an 'update-initramfs -u -k all' and rebooted just for good measure before proceeding. There's some output regarding a missing firmware file, I'm not sure it's relevant: root@rgrprod-pmdh-proc-03:/etc# update-initramfs -u -k all update-initramfs: Generating /boot/initrd.img-2.6.32-41-server W: Possible missing firmware /lib/firmware/ql8100_fw.bin for module qla2xxx Oddly, multipathd didn't log a single thing to stderr. ** Attachment added: "strace_mpathd.log" https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/1020436/+attachment/3218020/+files/strace_mpathd.log -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to multipath-tools in Ubuntu. https://bugs.launchpad.net/bugs/1020436 Title: Cannot read superblock after FC multipath failover To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/multipath-tools/+bug/1020436/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
