Description of problem: Anaconda to enable multipath configuration Additional info: Necessary feature would be: (assuming dm-multipath) - Discovering multipath (e.g. by using scsi_id) and present it as a dm-multipath device (Underlying devices may be hidden or shaddowed to disallow operation.) - UI to manually configure/deconfigure a multipath device (Manual configuration may be needed in case there is only a single path at installation time and extended after installation. Deconfiguration may be necessary to undo it.) - Present partitions on the multipath device (e.g. by using kpartx) - UI to edit partitions on the multipath device (transparent to normal device) - mkinitrd support for multipath root volume - Properly handling combination with other dm devices (LVM2, dmraid) (IMO, they are stacked as LVM2, md, dmraid, multipath from top to bottom. I'm not sure there is a device which has both multipath capability and dmraid support) There was a request for RHEL4 which was not accepted as of U3. I'm opening this for FC5/FC6, hoping the support in RHEL5.
Here here! I'm trying to do a boot-from-SAN install proof-of-concept and the installer is cripped in this respect - even a driver disk we could use with the multipath personality on it would be a good solution for now.
