RHEL 6 rawdevices service configuration using raw device
rhel5.0-5.3 canceled rawdevices service, then rhel5.4 over in support rawdevices service, now rhel6 not support, and many of them are using the Internet to do the bare udev device, rawdevices configure it a lot simpler. To study how to use under the following service on rhel6 rawdevices to create a raw device First Study
1. In rhel5.4:
[Root @ tanyangxf ~] # uname -a
Linux tanyangxf 2.6.18-164.el5 # 1 SMP Tue Aug 18 15:51:48 EDT 2009 x86_64 x86_64 x86_64 GNU / Linux
[Root @ tanyangxf ~] # cat / etc / redhat-release

[Root @ tanyangxf ~] # rpm -qf / etc / sysconfig / rawdevices
initscripts-8.45.30-2.el5
[Root @ tanyangxf ~] #
We found that the raw command from util-linux package, while /etc/init.d/rawdevices and / etc / sysconfig / rawdevices initscripts these two documents from the package, we look at the situation on rhel6
[Root @ node1 ~] # uname -a

Similarly, raw command also belong util-linux package (in fact, nonsense), in accordance with the above reasoning, the rhel6 actually less only two files, verify that:

These two documents are not the rhel6

Through this startup script we can find that this script is actually to read / etc / sysconfig / rawdevices information in this file is then used to create a raw device since the device can be created by udev naked through the raw command, that prove the core of nude equipment is supported, but this service redhat will rawdevices removed it, we can also verify the kernel supports raw
In rhel5.4:

crw-rw--. 1 root disk 162, 0 Mar 9 19:02 rawctl
The kernel is the support of that have to do now is simple, copy /etc/init.d/rawdevices and / etc / sysconfig / rawdevices these two files from the rhel5.4 to rhel6 system, then you can register at the service a.

# Enter raw device bindings here.

# An example would be:
# ACTION == "add", KERNEL == "sda", RUN + = "/ bin / raw / dev / raw / raw1% N"
# To bind / dev / raw / raw1 to / dev / sda, or
# ACTION == "add", ENV {MAJOR} == "8", ENV {MINOR} == "1", RUN + = "/ bin / raw / dev / raw / raw2% M% m"
# To bind / dev / raw / raw2 to the device with major 8, minor 1.
#ACTION == "Add", KERNEL == "/ dev / sdb1", RUN + = "/ bin / raw / dev / raw / raw1% N"
#ACTION == "Add", ENV {MAJOR} == "8", ENV {MINOR} == "17", RUN + = "/ bin / raw / dev / raw / raw1% M% m"

Restart rawdevices
[Root @ node1 ~] # /etc/init.d/rawdevices start
Assigning devices:
/ Dev / raw / raw1 -> / dev / sdb1
/ Dev / raw / raw1: bound to major 8, minor 17
done
Check whether the binding is successful
[Root @ node1 ~] # raw -qa
5. Add to the boot
[Root @ rac1 ~] #chkconfig --add rawdevices
6. Restart the server OK
reboot
