Title:
installing multipath-tools 0.5.0 on trusty leaves the system unable to
boot
Status in initramfs-tools package in Ubuntu:
Incomplete
Status in multipath-tools package in Ubuntu:
New
Bug description:
In order to test the fix for bug #1468897 on trusty on a POWER8 system
(PowerNV mode), Mike installed the multipath-tools package from wily.
This results in a system that fails to boot, dropping to the
initramfs. The reproducible failure is:
Begin: Running /scripts/init-premount ... done.
Begin: Mounting root file system ... Begin: Running /scripts/local-top ...
Begin: Loading multipath modules ... Success: loaded module dm-multipath.
Failure: failed to load module dm-emc.
done.
Begin: Discovering multipaths ... done.
done.
Gave up waiting for root device. Common problems:
- Boot args (cat /proc/cmdline)
- Check rootdelay= (did the system wait long enough?)
- Check root= (did the system wait for the right device?)
- Missing modules (cat /proc/modules; ls /dev)
ALERT! /dev/mapper/mpath0-part2 does not exist. Dropping to a shell!
