I just built a CentOS7 system on a Zotac NANO PC. I used a 320GB 2.5" HD I had sitting around and installed with Standard Partitions on XFS. The drive is spinning, nonstop. How can I monitor if there is actually disk i/o to warrant this constant spinning. So noatime for all partitions work with XFS?? I did some browsing and the claim is XFS uses realtime which is better? than noatime?

Hi all, When I ran the experiments to compare an application''s execution time in both a domU (named cctest1) and a native Linux machine (named ccn10), I noticed the application executes faster in domU. The host of the domU (named ccn9) and ccn10 are two nodes of a cluster and they have same hardware configurations. domU (cctest1) is created by exporting loopback files from dom0 on

I'm trying to work out the kinks of a proprietary, old, and clunky application that runs on CentOS. One of its main problems is that it writes image sequences extremely non-linearly and in several passes, using many CPUs, so the sequences get very fragmented. The obvious solution to this seems to be to use SSDs for its output, and some scripts that will pick up and copy our the sequences

HI, I am trying to find out why an old slower machineis faster than a new faster machine. I have a RedHat 6.2 server installation, it runs samba and I have been very happy with it. Filesystem is:- [darryl@keg darryl]$ df -h Filesystem Size Used Avail Use% Mounted on /dev/hda6 1.2G 735M 387M 66% / /dev/hda1 40M 3.0M 35M 8% /boot /dev/hdc1

What F/OSS does "secure erase"? And does it do

Hi Gang, I recently rented a server at a datacenter with Centos 5.7 X64, Q9550 Processor, 8GB Ram, and dual 250GB SATA HDs (with 16mb cache). They had loaded it with KVM, and installed a 30-day trial of Virtualizor as the front-end for KVM. I was so impressed with how fasts the guests ran that I want to build a few of these machines for myself. I just installed one: same Q9550 processor, 4GB

Hi All, just a quick question I could not figure out. Is there a way to export a PCI device to multiple VMs (para) keeping it available to dom0? Xen version is 3.0.4.

I'm having a wireless connection issue with an HP laptop and a Zotac media server after the 6.4 package updates from CR repository. Nothing changed with wireless config as far as I can tell. Both have been working fine with previous releases of 6.x. Oddly, if a cat 5 cable is connected for a few seconds and then disconnected the wireless works fine and survives a 'service network

Hi folks, I would appreciate it if someone can help me understand some weird results I''m seeing with trying to do performance testing with an SSD offloaded ZIL. I''m attempting to improve my infrastructure''s burstable write capacity (ZFS based WebDav servers), and naturally I''m looking at implementing SSD based ZIL devices. I have a test machine with the

Hello, can CentOS 6.8 be run on a mini-PC like this? https://www.zotac.com/product/mini_pcs/zbox-ci323-nano would like to configure this as a Firewall, and this should be instead of my router (integratet firewall, NAT) and wlan-ap Thanks, Walter

DBAN is obsolete. NIST 800-88 for some time now says to use secure erase or enhanced security erase or crypto erase if supported. Other options do not erase data in remapped sectors. Chris Murphy

I have a Dell PowerEdge 2950 and am looking to add more storage. I know a lot of factors can go into the type of answer given, but for present and future technology planning, should I look for a rack of SATA, SCSI, or fibre channel drives? Maybe I'm dating myself with fibre channel, and possibly SCSI? I may be looking to add a few TB now, and possibly more later. What are people

hi All, I''m new on the list. System: Distributor ID: Ubuntu Description: Ubuntu 13.04 Release: 13.04 Codename: raring Linux ctu 3.8.0-19-generic #30-Ubuntu SMP Wed May 1 16:35:23 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux The symptom is the same with Saucy 3.9 kernel. ii btrfs-tools 0.20~git20130524~650e656-0daily13~raring1 amd64 Checksumming Copy on

I am use to low random entropy on my arm boards, not an intel. On my Lenovo x120e, cat /proc/sys/kernel/random/entropy_avail reports 3190 bits of entropy. On my armv7 with Centos7 I would get 130 unless I installed rng-tools and then I get ~1300. SSH into one and it drops back to 30! for a few minutes. Sigh. Anyway on my new Zotac nano ad12 with an AMD E-1800 duo core, I am seeing 180.

At the present moment, my guest is running inside qemu and host is kvm intel, running Ubuntu 14.04, kernel is 4.3.0 stable. From within the guest, when I run "hdparm -i /dev/sdb" on the guest, I get: HDIO_GET_IDENTITY failed: Invalid argument as the error,but on the host, I will get the full harddisk/SSD info. Can I know how to resolve this so that the output is the same for both

Hello friends, I am trying to test NAS I/O performance over a network and trying to see the numbers for write and read speed. I have successfully configured and ran a lot of tests. However the numbers have not increased, I have reached a bottleneck. I tried playing around with the smb.conf file including all possible variations like, socket options = TCP_NODELAY SO_RCVBUF=(tried values like
