UDEV rules with GROUP setting do not change device's group in RHEL 6

Solution Unverified - Updated -

Issue

  • Example rule is as follows:
KERNEL=="dm-[0-9]*", PROGRAM="/sbin/dmsetup info -c --noheadings -o UUID -j %M -m %m", RESULT=="mpath-3600c0ff0001187d84ef7925401000000", NAME="oracle_data", OWNER="oracle", GROUP="oinstall", MODE="0660"
  • Notice the Group permission:
[root@localhost ~]# ls -l /dev/oracle_data
brw-rw---- 1 oracle disk 253, 11 Mar 27 13:14 /dev/oracle_data
  • Device is owned by user "oracle" as defined, but by group "disk" not "oinstall" as defined. This works in RHEL5, but seems to not work in RHEL6.

Environment

  • Red Hat Enterprise Linux(RHEL) 6.6
