- When using device-mapper-multipath, the devices appear in three different places. Which device should I use for creating Physical Volumes for the Volume Groups and Logical Volumes?
- multipath
/dev/dm-xnames are getting changed after reboot,dm-xdevice names are not remaining persistent across system reboots. - Need to change default path of a multipath device. I am using multipath and it looks like the default is to create the device under
/dev/mapper/mpath#. Then there's a symlink created under /dev/mpath#. I would like to change the default so that the device is created as /dev/mpath# and NOT a symlink?
