In Response To: Re: Problem with disk ownership (Art Kagel)

[root@oran1 rules.d]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.4 (Santiago)

[root@oran1 rules.d]# file /dev/dm-20
/dev/dm-20: block special

[root@oran1 rules.d]# ls -l /dev/dm-20
brw-rw---- 1 root disk 253, 20 Jan 12 22:06 /dev/dm-20

[root@oran1 rules.d]# cat /etc/udev/rules.d/60-raw.rules|grep informix
ACTION=="add|change", KERNEL=="dm-20", OWNER="informix", GROUP="informix",
MODE="0660"

[root@oran1 rules.d]# udevadm trigger

[root@oran1 rules.d]# ls -l /dev/dm-20
brw-rw---- 1 informix informix 253, 20 Jan 12 22:08 /dev/dm-20
