Comment: #6 - GIRISH SHRIGIRI <gshri...@in.ibm.com> - 2015-02-23 11:23:04 == multipath command should show boot disk . == Comment: #14 - Brian J. King <bjki...@us.ibm.com> - 2015-02-25 13:26:41 == There is a real issue in this bugzilla, and its related to the boot device. The reason the boot disk is not showing up in the multipath output is because the system is booting off a single path rather than the multipath device: root@zop01:/tmp/out# df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sdq2 59214188 7307684 48875468 14% / It looks like grub.cfg is mounting the root device by UUID. /etc/fstab is saying the root device should be /dev/mapper/mpath0p2. So it would appear there may be a boot time init script issue here. I'm thinking what might be happening here is that the boot process is not waiting for the multipath device to proceed with boot and simply mounting by UUID before the multipath device gets created, which results in us grabbing a single path rather than the multipath device. This should probably get mirrored to Canonical for them to have a look... I'm thinking that their scripts/local file in the initrd may need some changes to better handle this. You could probably change the root= parameter in grub to point to /dev/mapper/mpath0p2 and that may work around the issue.
