CentOS-7-x86_64-GenericCloud.raw very unusual format

Hello! Is anyone aware why CentOS-7-x86_64-GenericCloud.raw has such unusual format ? root@test-srv:~# wget http://cloud.centos.org/centos/7/images/CentOS-7-x86_64-GenericCloud.raw --2016-03-21 13:16:31-- http://cloud.centos.org/centos/7/images/CentOS-7-x86_64-GenericCloud.raw Resolving cloud.centos.org (cloud.centos.org)... 162.252.80.138 Connecting to cloud.centos.org (cloud.centos.org)|162.252.80.138|:80... connected.

Firefox and Chrome - dicking about with my volume.
by Gary Stainburn 14 Oct '16

14 Oct '16

I have Centos 7 installed on my laptop which works perfectly fine. I use a variety of music apps including VLS, mplayer and squeezelite. They all work fine, and using the KDE mixer app I have the levels set just as I like them. Why is it then that if i start up either Firefox or Chrome, whichever I start up first creates a new sound device which appears in the mixer, and then changes my master volume level. Firstly, why the hell does a web browser have to create a new sound device, and why the hell does it alter the master volume? Secondly, can anyone tell me how to take back control of my own music volume, and prevent both programs from messing with it?

Disable hybernate/suspend in CentOS 7
by Valeri Galtsev 14 Oct '16

14 Oct '16

Dear Experts, Could someone point me in the right direction: how can I disable hybernate/suspend in CentOS 7? I get workstations for graduate students with decent amount of RAM (32 GB), and for machines with large RAM I either do not have swap at all of have some small (4 GB) swap. As I remember from older manuals, one has to have at least twice amount of swap compared to physical RAM for hybernate/suspend to work. This probably is what bit me: new Dells came with keyboard that has sleep button, when one hits that button the machine locks up. (it stays powered on, does not respond mouse, keyboard, does not respond ping). I would like to disable that sleep button on keyboard. (I'm kind of trying to avoid replacing keyboard with the ones that do not have "sleep" key). Thanks a lot for all your help!

Backup Suggestion on C7
by Alessandro Baggi 14 Oct '16

14 Oct '16

Hi list, I'm building a backup server for 3 hosts (1 workstation, 2 server). I will use bacula to perform backups. The backup is performed on disks (2 x 3TB on mdraid mirror) and for each hosts I've created a logical volume with related size. This 3 hosts have different data size with different disk change rate. Each host must have a limited sized resource and a reserved space. If a server needs more space to perform backup, It must be enabled and provisioned. My first solution was put each host pools on different logical volumes, like: host1 -> lv1 host2 -> lv2 host3 -> lv3 and store pools/volumes on specified storage daemon that uses a specified device for each different hosts. host1 -> storage1 -> device_lv1 host2 -> storage2 -> device_lv2 host3 -> storage3 -> device_lv3 Unfortunately, I can't define on bacula-sd.conf multiple storage definition but only multiple devices. To use different storage I must run 3 bacula-sd on same host (I can?), run a bacula-sd on a vm/host. Ah, I must use only one physical server. With one single machine and the current state I can't use multiple storage daemons. There are other ways to store host volumes on different devices? My second solution was, use only one storage daemon (on the same host) with a single device LVM over mdraid, create pool for each hosts and limit the size for each volumes on related pool. Suggestions? Thanks in advance.

C7 and WOL
by Alessandro Baggi 14 Oct '16

14 Oct '16

Hi list, I've encountered a problem with wol. I'm not new to this but this time I found unwanted behaviuor. I'm triyng to wol another c7 machine. When I run ether-wake @mac the system is started. When I shutdown the system after 3 seconds it start again and again and again. To block this wol-loop I must disable wol on uefi or shutdown the switch. I don't know what check. Any suggestions? THanks in advance

gigE -> 100Mb problems
by John R Pierce 14 Oct '16

14 Oct '16

I've got a pair of identical CentOS 6.7 servers, with SuperMicro X8DTE-F motherboards, these have 2 each Intel 82574L ethernet ports. The eth0 ports are plugged in with 10' runs of brand new cat 5e cable to a Cisco Nexxus 9000 switch (provided by the data center). These servers keep coming up at 100baseT rather than gigE. I've swapped ports and cables with a different server, that server gets gigE but these supermicro's are stuck at 100baseT regardless of the port or cableused. 'ethtool eth0' says its gigE, but 'mii-tool -v eth0' says its 100baseT and doesn't even list gigE as an option, and the cisco switches see it as 100baseT too. anyone else run into anything like this before? -- john r pierce, recycling bits in santa cruz

Flash player beta

13 Oct '16

Has anyone tried the new flash player beta for Linux? http://labs.adobe.com/downloads/flashplayer.html I can't get it to work on CentOS 6.8, ff 45.3.0-1, all x86_64. ff's pluginreg.dat shows the plugin is [INVALID], which is often a sign of bitness-mismatch, but that's not the case here. $ tail -n 3 pluginreg.dat [INVALID] /usr/lib64/flash-plugin/libflashplayer.so:$ 1474541270000:$ $ file /usr/lib64/flash-plugin/libflashplayer.so /usr/lib64/flash-plugin/libflashplayer.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, stripped $ strings /usr/lib64/flash-plugin/libflashplayer.so | grep FlashPlayer_23 FlashPlayer_23_0_0_179_FlashPlayer $ rpm -q firefox firefox-45.3.0-1.el6.centos.x86_64 $ I have it working on a different Linux system, not CentOS, with ff 48.0.1.
