Everyone, I am putting together a new mail server for our firm using a SuperMicro with Centos 7.0. When performed the install of the os, I put 16 gigs of memory in the wrong slots on the mother board which caused the SuperMicro to recognize 8 gigs instead of 16 gigs. When I installed Centos 7.0, this error made the swap file 8070 megs instead of what I would have expected to be a over 16000

Yes to the first question, I'm not understanding the second

Thanks Chris for the detailed response! I couldn't understand the complex sentence about XFS and was almost convinced that XFS might offer a new way to spread across multiple disks. And in this case it's mainly me and not you. Now I understand how a md linear/concat array can be exploited with XFS! Not related directly but given that XFS has commercial support, it can be an advantage

Everyone, I recently added a 300gig Seagate sata drive on a Centos 5.0 and have a couple of questions. The drive was recognized with the device as /dev/sdc. The system came with some SCCI drives that are labeled as /dev/sda and /dev/sdb. I was surprised that the sata drives used sdc. Are the sata drives considered more like SCCI or IDE drives? The real problem occurred when I tried to

Everyone, I have installed Centos 7.0 on my homework machine in order to take a test drive with it, and am low on the learning curve with it at this point. I have a small Gateway SX2855-UB12P. I have a critical hurdle in that when I try a reboot or when I do a 'shutdown now -r' command the system will start a reboot process but hangs right after the os choices are presented. My

Centos 7 doesn't use runlevels set in inittab like previous versions did. I see that fact is actually noted in /etc/inittab, along with the expected way to do it. -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~

I have been playing around with customizing the centos to create a spin for my workplace. I am using centos 6.6 minimal, and trying to change the centos name to some random string. I have been able to change the name in the grub using grub.conf, but the name while the system is booting, I am not able to find a reference to that. Can somebody help me with that ? Attached screenshot. Anyhelp with

I have a lot of people whispering "zfs" in my virtual ear these days, and at the same time I have an irrational attachment to xfs based entirely on its lack of the 32000 subdirectory limit. I''m not afraid of ext4''s newness, since really a lot of that stuff has been in Lustre for years. So a-benchmarking I went. Results at the bottom:

Dear All, Probably a very basic question, but can't seem to work my way around it. I want to which row has the maximum value. But what if the row names do not correspond with the row numbers. In the example below, you'll see that the max of example is row 4, but the name of row 4 is "9". How do I get R to return "9" as value, instead of 4. example <-

On my 'older' systems that include Centos 5.5 and Fedora 12, vncserver is running on ports 580n where n is defined by userid in the /etc/sysconfig/vncserver I just spent a bit of time getting it working on my new Centos 6.3 server and found it listening on ports 590n. When did the change occur? And guess I should test out where it is on Fedora 17...
