Is there a package for zoneminder in the std repos (base, rpmfusion, epel), or just on rpmforge? mark "unless someone's got a security DVR to loan us for testing...."

Application Hang issue in RHEL6.4

UEFI booting
by Jerry Geis 06 Feb '14

06 Feb '14

Hi All, I received a Intel Nuc D34010WYK. nice and small. I installed 6.5 x86_64 on it in LEGACY boot mode on the mSATA disk. All worked except sound. In process of trying to get that working I saw posts about Need to not use LEGACY boot mode for HDMI sound to work. I am trying to find a document on how to use the UEFI boot on 6.5 Any great resource out there for that? Thanks, Jerry

yum update tries and fails to install libreswan
by Fred Smith 05 Feb '14

05 Feb '14

On 6.5, I've got openswan installed, but yum update is wanting to install libreswan. If libreswan is intended to replace openswan, wouldn't the appropriate yum transactions have been created to remove opnswan first? I'm stumped. Advice appreciated.

Read only nfsroot and diskless booting CentOS 6?
by David C. Miller 05 Feb '14

05 Feb '14

Does anyone have any good how-to's or documentation on setting up read only root NFS for pxe booting diskless computers? A few months ago I stumbled upon an official Redhat doc through a google search(not hosted by redhat and I cannot find it anywhere on the Redhat site) written by Dave Kline named "Configuring diskless clients with Red Hat Enterprise Linux" from 2011. It seemed to be a work in progress but the steps in it did work for doing nfsroot for one diskless client only. It did not have any explanation for doing read only nfsroot or how to deal with /var for multiple systems. I know there is a file in /etc/sysconfig/readonly-root but I could not get it working correctly. I did kludge together something for /var where during the init process I created a tmpfs for /var and rsync'd a copy of /var from an nfs mount. This worked, but again I felt it was a kludge to a proper solution. Although I got this working for booting an old bios based Dell and a VM via PXE boot, I don't know if it will work for newer UEFI based computers. I'm just looking to boot about 20 or so small modern PC's into a stripped down gnome desktop with a few apps installed. I still have not decided on the diskless clients I want to use. I was thinking either something like the low end intel NUC or one of the small AMD APU based PC's. David C Miller.

Experience with BTRFS?
by Lists 05 Feb '14

05 Feb '14

Was wondering if anyone here could weigh in on using BTRFS for CentOS 6 in a "near production" environment? I've been using ZFS on Linux and am very happy with the results so far, but don't particularly want to put all my eggs in one basket. Our application architecture allows us to have multiple, concurrent filesystems in mirror so I have the option of running a system under production-like environment without risking actual loss of customer data. In any event, we will be triple redundant at the application level, with ZFS on one file store, RAID/LVM/EXT4 on another, and possibly BTRFS on the third. Of course, I would want to use AT LEAST "release candidate" quality filesystem, but the ability of ZFS and BTRFS to check for errors and fix without downtime hold a tremendous amount of weight. The file stores are big enough that it is a days-long process to bring an offline file store back online. It would seem that BTRFS is slightly more flexible than ZFS, EG the ability to add RAID-levels for improved redundancy after initial creation without taking the system(s) offline. Anybody using BTRFS for real, sustained-load, 24x7 environment? -Ben

Scheduler Elevator Deadline
by Matt 05 Feb '14

05 Feb '14

In past on my machines with single drive or software RAID I have always had to change elevator to deadline. Mainly due to fact I was running email server with a great deal of I/O. Switching from CFQ to Deadline made a huge difference. I am wandering if with a hardware RAID controller should I still switch too Deadline or does the RAID controller do reordering etc. for me? Likely best answer is to try it. Doubt it would hurt anything to still switch too Deadline if I have plenty of CPU to spare. I am also trying to move all my servers to OpenVZ for hardware independence. When I need more disk space, CPU, etc. I just backup and move it. Perhaps there are gotchas there? Thanks.
