------- Comment From [email protected] 2015-03-16 15:48 EDT------- Per the internal discussion, this may be a duplicate of LP 1429327 / LTC BZ 122037.
During early boot (initramfs), the multipath command may run *before* the completion of the SCSI scan over FC ports, but the mount of root filesystem will wait for it. As a result, the SCSI disks over FC are not assigned to multipath devices, and the UUIDs will be assigned to them (because no mpathX devices will be created). Thus, the system boots off the one-path device rather than the multipath device, due to the root=UUID specification. If the bug reported run the multipath command after the system booted, there will be the mpathX devices for the SCSI disks over FC, but those were not present at the time the initramfs assigned UUIDs & pivot'ed the root filesystem. I'll be looking at this when the system is available for debugging. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1425773 Title: multipath command not showing boot disk information To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1425773/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
