those are potential issues with ANY high availability clustering

commonly use fencing technology to prevent split brain, dedicated

Re: [CentOS] centos 6.5 input lag

Is it under some type of ddos attack?

What's running on this machine? In front of it?

Subject: [CentOS] centos 6.5 input lag

I have a CentOS 6.5 x86_64 system that's been running problem-free for quite a 
while.

Recently, it's locked-up hard several times.  It's a headless server, but I do 
have IP KVM.  However, when it's locked up, all I can see are a few lines of 
kernel stack trace.  No hints to the problem in the system logs.  I even 
enabled remote logging of syslog, hoping to catch the errors that way.  No luck.

I ran memtest86+ for about 36 errors, no problems.

I've tried to strip away just about all running services.  It's just a home 
file server.  I haven't had a crash in a while, but I also haven't had it 
running very long.

But even while it's up, I have severe input lag in the shell.  I'll type a few 
characters, and two to 10 or so seconds pass before anything echoes to the 
screen.

I've checked top, practically zero CPU load.

It's not swapping - 16 GB of RAM, 0 swap used.  Most memory heavy process is 
java (for CrashPlan backups).

iostat shows 0% disk utilization.

Anyone seen anything like this?  Where else can I check to try to determine the 
source of this lag (which I suspect might be related to the recent crashes)?

Not yet, but I'm inventive.

BTW, the whole idea of "antivirus" is flawed. It is based on "enumerate

Good approach would be: enumerate good and ban everything else. Which we
usually do when configuring firewalls. Selinux (even though I have

it raises awareness of many admins as regards security of Linux systems and

always has been) a target in Linux systems. It may be Linux's "Code Red".
There are definitely more exploits out there.

Not all Linux admins are security aware, just as many are not backup aware.
Many think that Linux systems are secure by default. Many will "get around
to security" some time.

in this specific case, his threats of physical violence ( arguably,
death threats ) towards people are really not acceptable on this list;
and really content of that nature should not be acceptable in any sort
of group;

this is a technical list, largely self moderated, and very well
established + respected in the peer group. Lets try and keep content to
the technical conversations, ideally CentOS relevant.

Ah, yes, I missed the OP's reference to mysql.  Sorry about that!

mysql/mariadb replication is a reasonable way to go, and probably has
more eyes on it than lsyncd.  MariaDB's somewhat new GTID replication
might be more reliable than the old query/row/mixed replication scheme
they had before.

[CentOS] Conduct on the CentOS List

2014-10-09 Thread Karanbir Singh
-BEGIN PGP SIGNED MESSAGE-
Hash: SHA1

The recent anti-social content on the list including threats and
support of harassment needs to stop immediately. The CentOS Board
will work with the list admins to enforce moderation and if needed
removal and bans from the list should people continue this behaviour.
This is a large, diverse, and respected community and none of us
should need to tolerate any form of uncivilised behaviour, such as
harassment and threats.

The topic of harassment and online threats has been at the top of mind
lately, and in light of the conversation we would like to make it
clear that the CentOS Project is not a place for abuse or hostility.
There is no excuse for this behaviour, no matter what the intention.

Discouraging and banning anti-social behaviour in the CentOS Project
has been part of an ongoing effort for a while, and now we feel it's
time to come forward with a clear statement.

As with any open community, we have disagreements on technical
matters. It's part of the natural exchanges needed for a vibrant
community, but we must keep the discussions civil. Have consideration
and respect for other people.

The power of an open source project is in the community. If the
community gets broken, the project loses its fundamental
reason-for-being. Code alone does not make open source, and community
is made through people treating each other with respect.

* Do not make personal attacks
* Do not threaten people
* Do not harass people
* Do debate ideas on the merits of the idea alone
* Do help each other keep a civil tone while remaining civil
* Do treat others with respect

In your communication on CentOS Project forums such as IRC, mailing
lists, Web forums, or any other medium, we will not tolerate personal
attacks, threats, or harassment of any individual or group. We reserve
the right to moderate or ban anyone who violates our guidelines without
notice or discussion.

Thank you for your attention to this important matter.

Thanks for the reference. I follow FreeBSD Handbook, sorry I only looked

what I do by following Handbook. But thanks anyway. I guess, we need to
move this discussion away from this list before we are banned (and

Jails are great.  Although we had this great setup that worked up to 9.2
with jails on nullfs (that is, a bunch of jails sharing a template)  that
from 9.3 (maybe) and 10.0 (definitely) require an rc.local script to mount

 I was going to post about this earlier, but got distracted ...

 Add-ons are totally broken on C5/ff31. All of them download, some of them
 continue to install (without the installation progress bar showing any
 signs of it), and for most add-ons, nothing happens after that. Sometimes,
 the add-on will install when the manual installation option is selected and
 the downloaded /tmp/xxx.xpi file chosen, but most of the time this does not
 work either. This also prevents updating of add-ons.

 What does seem to work is to log into a C6 box to install add-ons, no such
 problems there.

a cluster management package, such as the ones suggested by another

properly), if the master fails, it would 'activate' the slave, switch 
its IP[*] over to be the 'production' system, and mount its file 
systems, starting its services (mysqld, postfix, etc) per your 
configuration.

IP for each system, used only for management, and a 'service' IP used 
for the production accesses, which is held by the currently active 
system.   when the master fails, the slave adopts this service IP.

"human factor"  means it is extra work for someone who was already
using a linux distribution because it did what they wanted - which
doesn't seem good to me either.  And since I don't understand it, I
don't know how to prove that some arbitrary addition can't cause a
dependency loop when added to some arbitrary existing configuration.
Do you?

No, it is a very real scenario for me.  If I leave the upgrades for
someone else it will probably be the end of linux use here.

Assuming of course that you dont need any kind of performance from your
filesystem drdb is indeed the answer.

ZFS snapshots can however be run on a per second basis which is quite neat!
What ever you choose to do you would probably want to use mysql binary
replication anyway so having a completely sync filesystem replica is
probably not too much of a problem.

I must point out that virtualisation made these kinds of problems mostly go
away (assuming of course that you have cash for some kind of High
Availability iSCSI device or something.

An interesting idea, that was born in your head, right?

With databases you can not make sync of their data directories (on a
filesystem level) while the daemon is running and accessing them in
general. You may think of mysql redundant server or replication... Take a
look here:

Its not perfect if you don't want to lose all database transactions, new

drbd really is the best answer as its continuous in-order replication.

rsync is only safe to use on something like a database server if you 
stop the database each time you run rsync, otherwise the files will get 
out of sync.


I suppose you could setup mysql replication, and exclude mysql from the 
lsyncd/rsync, that would be one approach.

You can try lsyncd.

It's basically a daemon monitoring inotify events and sending them to an

drbd is the live replication system, this does block level replication 
of logical volumes.   rsync doesn't handle changing-on-the-fly stuff 
very well, especially stuff like a database file system which is

It is much simpler to run remote X sessions over a network for

Or a raspberry-pi for $50 if you don't have an old PC.

Umm, Wal-Mart?  Best Buy?  You do realize that AMD/ATI Radeon chips (for

Yes, "much too cavalier about bugs and compatibility" is exactly
right.   Never mind the fact that you break everything you existing
users have done, you might attract some people who like windows and
don't understand that it took decades of patches and reboots every
Tuesday to reach any kind of stability with its monolithic approach.

Car vendors might behave differently however.  Particularly if they obtained

If I'm not mistaken the "cost" of switching between processes also adds to

No, at the moment I run services in FreeBSD jails. Even a single host

go to different jails). But don't confuse me for an expert here...

refreshing update to Linux, and I welcome the fact that Linux is
becoming a little more Windows-like. 

whatever your opinion about Windows may be -- you can't argue its huge

Not that simple. Smaller things none of which on its own make you make
fundamental decision just accumulate, so after some critical mass you are
there, the decision is made. I probably will not remember all of them, and
definitely not in the order of their arrival.

1. SELinux (it doesn't not pass _my_ "security has been enhanced"
estimate. It can be turned off on the fly, therefore it is as if it
doesn't exist. It adds tens of thousands of lines of code to the kernel,
thus increasing chance of bugs and deteriorating security. And once my
estimate was confirmed: "critical security update of SELinux"...)

2. The need to reboot linux box often (on average every 45 days in my
observation...). I know, there are workarounds to patch on the fly...

3. Firewalld. I'm tempted to say: the philosophy it's based on is flawed.
Hey, this is our institutional internal network which is behind strict
firewall, so we consider it "safe" zone... Nope. Wherever is the machine
that _you_ do not administer, you better do not consider it "safe" or
"secure". It uses the same iptables kernel module, right? And you can
switch to using iptables instead if it, right? Only one day you end up
running distro with stripped this, stripped that... Small thing in itself
as I said.

4. Systemd. ("If it ain't broke, don't fix it"). I don't want to start
flames again...

And things add up gradually till you realize this. If I were willing to
run M$ Windows I would pay for it, and will curse it legitimately as I
paid for it and my money entitles me to curse it. Now I run free open
source system courtesy of uncounted number of generous developers. I
should be grateful to them and tolerate new routes they take - which is
usually their only reward for their work... So, when I can not tolerate it
any more (... accumulated above critical mass), I just go to another also
open source system, thank goodness, they still do exist...

I have.  And I know how to.  Ascii sort order is a straightforward
concept for both humans and computers.  I knew how to deal with
scenarios with subtle issues like the network service 'completing'
startup even though the connected switch was still doing spanning tree
and the next network operation would fail.  And now I don't know how
to tell how introducing some new arbitrary service will interact with
an existing arbitrary set.

I have.  And now those won't work the same way.  So why was using that
abstraction good?

I read them at the important times.  When things aren't working.  The
ones shipped with the system have already had years of breakage
gradually fixed in fedora.  Our local apps will have to start from
scratch.

You are just deferring the pain unless you plan to retire before EOL

Are you serious? Do you provide manually the links for the sysV fs? 
Or do you use an "wrapper/helper" (e.g. ntsysv, chkconfig)? So why 
not using the same work-abstraction for a different boot process? 

And about readability - do you read all configuration files on every 
system boot? No - but the system does and therefore xml is more suitable. 

Please don't misunderstand me. As I tried and mentioned before - the 
whole disarmony here is more based on human and not on technical factors. 
I am on your side but for sure for different reasons. EL7 has changed
to much not only the boot process. The cluster stack, IPsec implementation 
and httpd config syntax is different, NM for network, gnome-shell, missing 
TB and so on. Further investigation and adaptation of our deployment processes

I have a similar Intel card on a machine (not near it right now) which has the 
same kind of text issues.
The trick I learned was to log out and log back in.
i.e., you have to know which " ys em" and " og O t" menu items get you to  log 
out and do that.
When GDM comes up the next time it will be good.

Be glad your GDM comes up so you can see it for the first login, Mine was a 
black screen with a pointer.

Wish I knew how to tell X to just restart itself after initializing the card.  
BTW if I recall correctly, telinit 3 && sleep 5 && telinit 5 ;  will return me 
to broken text so no help there.

Even when this disclaimer is not here:
I am not a contracting officer. I do not have authority to make or modify the 
terms of any contract.

The feature of advantage is fast boot. As Linux like Windows needs reboot
often, it is awfully important. And all of you, dinosaurs (who saw years
long uptime of Linux machines) who don't care that boot takes 60 seconds
now instead of 4 minutes should just shut up.


Let me second what you said. I also would add: In my opinion it is not
clever to keep settings that are expressed by plain ASCII text being
marked up, "dressed into junk", XML. For human to read them you need
"undress" them (you GUI guys may forget that your GUI does that - not
literally of course), and to pass them to systemd itself one has strip the
junk (XML markup). The same goes about firewalld.

But what am I doing. The World passed that point...

[CentOS] removing menus

2014-10-09 Thread Jerry Geis
I am attempting to get no menus on the desktop... for CentOS 7.

I did:
rpm -e --nodeps gnome-shell-extension-apps-menu
rpm -e --nodeps gnome-shell-extension-places-menu

But now I get an "Activities" menu at the top... instead.

Any idea how to remove that package... I cant find what it is called.

I had to use --nodeps above as gnome-classic (I think) needs to be
installed or nothing works.

Thanks,

Jerry

Really?  What application could you not start with sysv init syntax?
What CPU has become too slow to start things serially?  What feature
do you need that could not have been added without breaking other
existing work?

Although, this is already in there:

"We can reproduce this parser bug.  But we treat this as a regular bug,
not a security bug, because of the fixes mentioned in comment #1."

So, I would imagine that statement means that they are going to fix the
segfault  issue as a RHBA, not an RHSA.  This likely means it will
happen, but the QA and regression testing will be longer and more
thorough as it is not a time critical security issue.

Well, the upstream patch, at least as it is written now, would require
them to back out their patches to apply.

But regardless if whether or not they fix the segfault issue, that is
NOT a security issue or exploitable.

It might possibly be a Denial of Service mechanism, I guess.

The place to address this is on the bugzilla entry though.  We will
publish the changes Red Hat rolls into the source and the upstream
bugzilla is how to make that happen.

If I understand it correctly they think it's not exploitable anymore. 
Still think it should get patched immediately as there is an upstream 
patch available and it avoids any more questions and confusion about this 
problem.

 resp., are still vulnerable to CVE-2014-6277. In fact, on CentOS6, abrtd will
 send you a nice report about it. Does anyone know if upstream is working on a
 fix?

I wonder why personal implications are communicated without explained reasons 
(because all are screaming doesn't mean its valid). "Changes" have inherent 
implications by it self - it doesn't matter what was the change. Take a look 
back (or step) and try to see what is being ignored, changes all over the 
community projects (e.g. kernel, gui, distros, wm, nfs, config syntax). So 
whats 
the point and why bothers other, if the problem [1] lies in our selfs? BTW, 
you have the choice.

[1] problem definition: actual state = EL6, goal = EL7 and something that 
is preventing the transition (and that is for sure nothing technical).

PS: I'm not taking a position for systemd - just seeing some kind of structure.
