bare-metal backup before update--options?
by Fred Smith 12 Feb '19

12 Feb '19

Hi all! I'm a "nervous nellie", I have not yet updated my 7.5 desktop to 7.6 because (1) it has an Nvidia card, and (2) I've heard of problems upgrading on top of software RAID (using RAID1 with 2 drives). I need to upgrade it to stay secure, and I want to do a bare-metal backup first (so I can put it all back as it now is, in case it explodes in my face), so I'm trying to figure out the safest way to do that. Here are the choices as I see them, I'd appreciate comments/thoughts: 1. boot from live DVD and manually reassemble the RAID array (how would I do that?) 2. degrade the array (with appropriate commands) so that it is running on just one drive, then boot a live DVD and use dd to back up that drive. 3. Other choices you can suggest? then after successfully getting a bare-metal backup, reboot it with the full RAID array and run the update. Thanks in advance!

time --verbose not working
by Robert Moskowitz 11 Feb '19

11 Feb '19

I can't seem to get the verbose mode of time working. I am trying to compare the compute cost of sha256-crypt to sha512-crypt: time doveadm pw -s sha256-crypt -p secret real 0m0.128s user 0m0.081s sys 0m0.040s time doveadm pw -s sha512-crypt -p secret real 0m0.162s user 0m0.105s sys 0m0.047s But all attempts to add --verbose fail: time --verbose doveadm pw -s sha512-crypt -p secret -bash: --verbose: command not found Googling gives different recommendations, none work for me.

Latest kernel crashes X and gnome
by Rob Kampen 10 Feb '19

10 Feb '19

Hi, Anyone else having problems with kernel 3.10.0-957.5.1.el7.x86_64? After my yum update today a reboot hung. A quick look at the Xorg.0.log shows two of my graphics cards appear to be working okay but the third one (I have two nvidia cards with a monitor each and then use the inbuilt intel one for the third monitor) gives: <cut> [ 14.246] (II) Loading sub module "fb" [ 14.246] (II) LoadModule: "fb" [ 14.247] (II) Loading /usr/lib64/xorg/modules/libfb.so [ 14.247] (II) Module fb: vendor="X.Org Foundation" [ 14.247] compiled for 1.20.1, module version = 1.0.0 [ 14.247] ABI class: X.Org ANSI C Emulation, version 0.4 [ 14.247] (II) UnloadModule: "vesa" [ 14.247] (II) Unloading vesa [ 14.247] (EE) modeset(G0): drmSetMaster failed: Invalid argument [ 14.247] (EE) Fatal server error: [ 14.247] (EE) AddScreen/ScreenInit failed for gpu driver 0 -1 [ 14.247] (EE) [ 14.247] (EE) Please consult the The X.Org Foundation support at http://wiki.x.org for help.

Closing log file. </end> So a reboot to kernel 3.10.0-957.1.3.el7.x86_64 and all is well. I note that the update also updated : Updated xorg-x11-drv-ati-18.0.1-1.el7.x86_64 @base Update 18.1.0-1.el7_6.x86_64 @updates Updated xorg-x11-server-Xorg-1.20.1-5.1.el7.x86_64 @updates Update 1.20.1-5.2.el7_6.x86_64 @updates Updated xorg-x11-server-common-1.20.1-5.1.el7.x86_64 @updates Update 1.20.1-5.2.el7_6.x86_64 @updates Before I start trying to solve this by myself, just wanted to see if anyone else has had issues. TIA Rob

firefox-60.5.0-2.el7.centos.x86_64 and Netflix
by Bernard Lheureux 09 Feb '19

09 Feb '19

Hi all, Since the last upgrade to firefox-60.5.0-2.el7.centos.x86_64 on my CentOS 7, it is no longer possible to watch Netflix with my Firefox, it always says that "Firefox is installing components needed to play the audio or video on this page. Please try again later." But nothing happens and Netflix is no longer readable with Firefox... I tried downgrading to firefox-60.4.0-1.el7.centos.x86_64 and al is now correct with Netflix... Anyone had experienced the same behavior ? -- (°- Bernard Lheureux //\ Linux System Administrator v_/_ MailTo:bernard@lheureux.be

CentOS 7, rsyslog and redis
by Pete Biggs 09 Feb '19

09 Feb '19

TL;DR: Is there a sensible way to get rsyslog to talk to redis on CentOS 7. The official way is to use the omhiredis plugin, but that doesn't seem to exist in the CentOS 7 repositories? (It's how I do it on my Fedora box.) The long version: I'm trying to rationalise logging and am using an ELK stack. When I've done this in the past it has suffered badly from congestion at peak times with messages being dropped and various issues on the clients. The sensible thing seemed to be putting redis between the clients and ELK - that works in my test setup from a Fedora box. My problem though is ingesting the logs from my CentOS servers. By far the easiest thing is to get rsyslog to send things directly to redis, but that needs the omhiredis plugin. The second choice is to use filebeat to scan the log files - but if I want to have things like facility and severity logged, I have to use custom rsyslog templates and it's a pain trying to get filebeat to parse them (and the filebeat redis output seems a bit flaky as well). I can see that syslog-ng has redis support, but I would prefer to keep rsyslog since that is the default. So, what do people do to ship their logs to ELK (or, specifically, logstash). Is there some magic, neat solution? Or do I keep just hammering away at filebeat -> redis -> logstash until I get something that's reliable? Or do I go down the syslog-ng route? P.

CentOS 7.6 update with gettimeofday()
by david allan finch 08 Feb '19

08 Feb '19

In my app compiled on another linux I am getting Assertion 'clock_gettime(clock_id, &ts) == 0' failed at src/shared/time-util.c:34, function now(). Aborting. when calling gettimeofday() on an update CentOS (did not fail in 7.5). Is it possible that the update has changed the size of the types in the timeval struct and causing the crash? Or has there be some for of bug fix etc? Regards
