Package: multipath-tools
Version: 0.4.9+git0.4dfdaf2b-4
Severity: important
This could happen if you have no dm understood root device.
rrs@champaran:~/Community/Packaging/pkg-lvm/multipath-tools (master)$
sudo /etc/init.d/multipath-tools stop
Device does not exist.
Command failed
If a user's setup is direct access to scsi device, be it either sd
naming scheme or persistent names, it appears that no entry for it is
created in /sys/block sysfs hierarchy.
In this scenario, the multipath-tools' stop target fails thusly breaking
all upgrades.
Current resolution is to run the init script to survive errors, i.e. "!sh
-e"
