How to Change Owner and Group of Device-mapper Mutipath Device?
Issue
If you wants to install Oracle 11g R2 in RHEL5 with raw device through multipath.
By defaut, the owner of multipath device is root, and the group is disk.
# ll /dev/mapper/mpath0
brw-rw---- 1 root disk 253, 2 Jan 21 14:33 /dev/mapper/mpath0
But the installation of Oracle 11g R2 needs the owner and group of multipath device are both oracle.
So change owner and group of multipath device is necessary.
