Are you talking bearing in mind VirtualBox?

I've created a bridge on the host machine, and 2 VM's but br0 has no slaves:

[sergio@hope share]$ sudo brctl show  br0
bridge name bridge id   STP enabled interfaces
br0 8000.   no

yeah, you're probably right. but for some reason, Anaconda is still
telling me there's a gigabyte of unused space remaining (105x megabytes
where i've forgotten what the "x" was.) Might that be because I
didn't put swap on both drives (and I think I set up swap as a gig)?

should I put swap on both drives? should it be RAID1 also, or just
two swap partitions not in any RAID volume?

(I remember seeing a somewhat technical article in the last couple
of  years that talked of a potential corruption issue if one puts
swap into a  Linux software RAID-1 volume, but no longer recall
the details.)

Thanks, Jim.

If I knew who to email, I'd email his manager, and have this unqualified
incompetent fired... *after* they yanked his access and changed the
password.

Actually, *what* the password is makes me wonder whether he's actually
legitimately accessing that system as root

I have an original-label Infrant (now NetGear) ReadyNAS storage

I use it primarily as a backup device (via NFS) for a couple of Linux
machines, (via SMB) for a couple of Windows PC's, and (via ftp) for web
sites at my hosting provider.

SMART+ reporting shows ~75K hours operation, with zero sectors
reallocated, on each of the four disks.

I'm thinking I should be looking for a replacement, even with all this
good info/luck.

Would like to hear recommendations here.  Besides the ReadyNAS, I have
worked with a Thecus NAS (don't recall model). What are the features I
should look at?



Just closing the loop here.  Thanks for all the replies and 
recommendations.  As usual, discussion went far and away beyond what I 
needed for my decision--but I was interested to read all the messages.


For my home/home office solution, I've decided to stay with the ReadyNAS 
line (the Model 204, 4-slots, for $370, with four WD Red 2TB disks). Was 
tempted by the Thecus similar model N4800ECO ($100 more). The 
even-more-expensive QNAP TS453 Pro model seemed more than I needed, as 
did the Synology DS415+--and I was put off by a rather negative review 
of Synology service).

Also, it's worth mentioning that there's no such thing as CentOS 5.5
-- if you're running that, there are a large number of critical
security fixes which are not present. If you pay for RHEL 5.5, then
you'll have something much safer. With CentOS, you must stay with the
tip to be reasonably secure.

This is explained, somewhat confusingly, in

Two thoughts: one, as Gordon suggested, it might be making a /boot
partition. The other thought is that it might be trying to align the
partition optimal. Still, that's usually 1M or 2M, not 1G.

Btw, when I manually create partitions, with parted, I use
mkpart pri 0.0GB 100% (for data drives). Assuming I've gone in with parted
-a opt, it does the right thing. Hope this gives you some ideas.

[CentOS] Help with Intel 6235 Wireless on CentOS 7 (pointer to good reading?)

[Valeri Galtsev]

Dear Experts,

I would like to ask your advise on good reading about how to add WiFi
device, and how to control its settings on CentOS.

Sounds really dumb, but this is what I am NOT able to do on CentOS 7 what
I was able to do in the past, beginning somewhere since RedHat 5 or 6,
through Fedora and up to CentOS 6.

In brief: my card is Intel 6235; CentOS 7 (fully updatted), latest kernel
(3.10.0-229.20.1), relevant Intel firmware version for my card is in
/lib/firmware (together with large bunch of other Intel WiFi firmware),
relevant modules are loaded in kernel:

iwlwifi
iwldvm
mac80211
cfg80211

"/sbin/ifconfig -a" shows my device in the list renamed to wlp3s0
(according to PCI slot numbering I figure), dmesg shows device brought up
successfully detected and renamed as above. lspci shows device with its
correct full name (Network controller: Intel Corporation ... 6235"

Now comes the fun part (no, troublesome for me part). When I click on the
NetworkManager Applet in right top corner, there are no WiFi devices. I go
to Network Settings from there. My device is in the list under name "PCI
Unknown". I click on that, the device is described as "unmanaged", and
there is no way to make changes to the contrary to other devices (correct
MAC address is displayed).

OK, I assume I just need to declare device as NM_CONTROLLED. There is no
relevant /etc/sysconfig/ifcfg-wlp3s0 - where I know I can declare that. I
use "nmtui" to add configuration, then add to ifcfg-wlp3s0

NM_CONTROLLED="yes"

line. Reboot. Still the same.

Just for comparison I booted Ubuntu 14.0.4 x86_64 live CD. Yes, it can see
my wireless, and I can connect to WiFi networks. Kernel is just a notch
newer (3.13.0.24) which shouldn't matter according to Intel information
which kernel versions this device is supported in. List of relevant kernel
modules loaded by ubuntu is exactly the same. I don't see anything weird
like the need to separately load firmware as kernel module (yes, indeed
I'm going nuts, that would be "freebsd-ism" I guess).

I do not want to have Ubuntu (or Debian which likely will work out of the
box too) on this laptop. So, apparently I need a pointer to good reading
on how do we do it on CentOS 7 "dirty way" - when "click here, choose in
menu that" doesn't work.

Thanks a lot for your advises!

Valeri

I really recommend using the fewest partitions possible, since md RAID 
operates on partitions (Anaconda won't create full disk md RAID 
volumes), and replacing a disk will require you to handle each partition 
individually.  It's probably best to do a small /boot on RAID1 and use 
the rest of the disk for a second RAID1 volume, with LVM on that.

There's no corruption.  If a write is canceled before it completes, you 
might end up with a block mis-match (or might have, I'm not sure if that 
still happens), but no corruption.  The mis-match is on a block that 
isn't mapped to anything, and will never be read by anything other than 
a RAID verify.  It's ugly because it means the verify operation is no 
longer useful, but it won't cause any read from the RAID volume to 
return bad data.

Re: [CentOS] Poor perfmance of bridged interfaces

[Gordon Messmer]

On 11/25/2015 07:18 AM, Sergio Belkin wrote:

Are you talking bearing in mind VirtualBox?



Actually, no.  I'd either missed that detail or forgotten it by that 
time in the conversation.  This might be the wrong list for VirtualBox 
questions, since it's not distributed with CentOS.  I've worked with 
VirtualBox only a little bit, and I'm not sure what you're trying to do 
is possible.  I think it is, but I can only really describe how to 
accomplish what you're trying to do with respect to libvirt/KVM (the 
virtualization platform that's distributed with CentOS).


Anyway, the first thing you'd want to do is create a bridge interface 
with no slaves, and then create two VMs.  They should be attached to 
that bridge device.  (In virtualbox you might be able to do that with 
"bridged networking" to br0, or you might be able to skip the virt host 
bridge and use "internal networking".  Try the former first.)  The two 
VMs will not be attached to the real network, but should be able to 
reach each other.  Now your topology looks like this:


 ---| Network |---| (eth0)-VM Host-(br0) |--+| (eth0)-VM1 |
\| (eth0)-VM2 |

...your virtualization host is connected to the real network on eth0. 
The two VMs are attached to its br0 interface.  They each have one 
"ethernet" interface and can communicate with each other.


Once you've set that up and verified that it works, set up a new bridge 
interface, br1.  Move the IP configuration from eth0 to br1, and make 
eth0 a slave of br1.  Make sure the virtualization host has network 
connectivity.  Your network topology looks exactly like it did before, 
except that the virt host uses br1 (with eth0 as a slave) to connect to 
the real network.


 ---| Network |---| (br1)-VM Host-(br0) |--+| (eth0)-VM1 |
   \| (eth0)-VM2 |

Next, you can add a second interface to VM1.  This one will be connected 
to br1.  (again, in virtualbox, you might be able to do this with 
bridged networking.)  Give VM1's new interface (it's eth1) an IP 
configuration appropriate for your real network, and verify that it has 
full internet connectivity.  Now your network looks like this:


 /--| (eth1)\
 ---| Network |---| (br1)-VM Host-(br0) |--+| (eth0)-VM1 |
   \| (eth0)-VM2 |


So, now VM2 can reach VM1, but not the real network, and VM1 can reach 
the real network.


Finally, you'll create a bridge interface in VM1, and make both of its 
"ethernet" interfaces slaves.  Move its IP configuration from eth1 to 
its new br0, and drop the IP configuration from eth0.  This will give 
VM2 connectivity to the real network, so update its IP configuration to 
be compatible with the real network.  Now your network looks like this:


/--| (eth1)\
---| Network |---| (br1)-VM Host-(br0) |--+| (eth0)-(br0)-VM1 |
  \| (eth0)-VM2 |

When VM2 transmits a packet, it will be sent out VM2-eth0, across VM 
Host br0 to VM1-eth0, across VM1-br0 to VM Host-br1, to the real network.


And most importantly, no bridge connects two interfaces to the same 
broadcast domain.  VM Host's br0 creates a collision domain spanning the 
two VMs.  VM Host's br1 creates a collision domain spanning the physical 
network and VM1's eth1 interface.  And VM1's br0 bridges those two 
collision domains.  No loops.


I don't know what performance will look like under VirtualBox, since I 
don't use it for this sort of thing.  However, under KVM/libvirt, 
performance should be fairly good.

Sorry for the delay.

I grabbed libvirt-python-1.2.15-1.el6.x86_64.rpm from:
http://buildlogs.centos.org/centos/6/virt/x86_64/xen/

rpm installed fine. After that virt-manager and virt-viewer installed fine too. 
virt-manager seems to start/run fine aswell. I'll play with it more now.. 

So the main issue seems to be fixed with that libvirt-python build!


Thanks a lot,

So, one thing to keep in mind : sending the same mail to the same list

I've been looking in various ways, and I just checked another Windows
system - this one is a single users (as opposed to a server), and it's the
same: a) it seems to have completely flattened the directory structure,
such that everything is visible in one directory, and b) not just from one
user, but all of them.

*sigh*

I was just trying to restore one single file... but as I said, I can't
even find it.

[CentOS] SOLVED: Help with Intel 6235 Wireless on CentOS 7 (pointer to good reading?)

[Valeri Galtsev]

My original problem is solved: it turns out that I just needed to install

NetworkManager-wifi

rpm (which adds WiFi plugin to network manager). Now I'm back in happy GUI
world in which everything "just works". Like on Macintosh... only better
;-)

Valeri

PS beats me why I needed to install it separately though, i.e. why it
wasn't installed with "development workstation" (plus bunch of extras) rpm
set...

Are you sure that you're running CentOS 7 and not some kind of VPS
(using a shared kernel, and on which you can't modify iptables rules) ?
What about "modinfo ip_tables ; uname -a " ?

Which should be under
/lib/modules/3.10.0-229.20.1.el7.x86_64/kernel/net/ipv4/netfilter/ip_tables.ko
... so something else is broken on that node.
Back to the initial question : which kind of setup is that :
bare-metal, or a VM, VPS ? how was it installed, etc .. (because that
ip_tables kernel module is there *by default*)

The more details you can give, the better, as at first sight that
doesn't seem to be a normal setup

OK, well in the absence of testing, it works for me, so I've tagged it
to go to the main repo, and Johnny will be pushing the updated
centos-release-xen to centos-extras tonight or tomorrow.

Re: [CentOS] Poor perfmance of bridged interfaces

[Sergio Belkin]

Perhaps I don't explain myself enough.

I don't want to "bridge" physical machine with virtual machine, my idea was
create a transparent bridge in  a VM for example to demonstrate a proxy
with no need of topology change.

[CentOS] About CentOS Marks

[Takuya Yamamoto]

Hello

https://www.centos.org/legal/trademarks/

According to above, I found following message.
--
Notwithstanding anything to the contrary provided in these Guidelines, the 
following are examples of unacceptable uses:

1.Use of the CentOS Marks in connection with commercial redistribution of 
CentOS software
--

I have a question.
What means "Use of the CentOS Marks"?

For example,
While CentOS is booting up, CentOS show the CentOS logo on Full screen.
Is it unacceptable? Or acceptable?
If commercial redistribution of CentOS software, Developer have to hide this 
logo?

For example,
CentOS System is working, user can show the "CentOS" text words on console.
Is it unacceptable? Or acceptable?

Well, usually pricing is ~about 100-250 dollars/hour, depending on how
complex case and contractor.

How about learning the basics? Commercial support is also available, if you
really need some one to fix your server.

if he agreed to you opening (or backing) the case that would be great. I just 
became aware that my developer account is not entitled to raising issues :-(

I can send you the reply of RH offline if you want to handle this further.

[CentOS] Regional CentOS Specific Meetup groups

[Karanbir Singh]

Hi,

Just a quick post to say that I've setup a CentOS users group in the UK
at http://www.meetup.com/CentOS-UK - aim to start organising regular
demos and meetups face 2 face around the country. If you are based in
the UK, I encourage you to come join the group.

Also note that we have a CentOS group in India at
http://www.meetup.com/CentOS-India/ and another group for the
Netherlands at http://www.meetup.com/CentOS-Netherlands/

Regards and hope to see you at one of these meetups soon,
