If they are 4 independent disks then you should just see them as standalone disks, if they were in RAID 1 or RAID 5 there would not be 4 disks, there might be 2 for 2xRAID 1s, or 1 with RAID 5. Assuming your using hardware raid of course. If you are using hardware raid depending on the controller/driver you can query it for it's configuration. If your using software raid it should be pretty easy to determine it's configuration as well(last I ran software raid I would just cat /proc/mdstat) > Second question - A newly installed server consisting of CentOS 5.2, > straight > off the DVD, I invoke a command by hand, realize I want to kill it soon > after > (logged in as root).

Is the process state "D" or "Z" ? Frequently either of these states can trigger an unkillable process. Sometimes "Z" (zombies) can be killed but often times they can't be directly killed. And if the process is in "D" then it is stuck waiting for I/O(most often) and you have to wait for it to complete, or reboot, sometimes going to single user mode and back again works as well, and sometimes killing other processes that the stuck one depends on can sometimes free it up so it can die. If the process is zombied you can try to find the parent process (if there is one) with ps -efx, and kill that sometimes that can cause the child to die as well, doesn't always work though. nate _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
