Re: [CentOS] Restore the moved directory

[beklan]

Hi, 
I used the partedmagic cd to move the etc directory from /home/ to / . When
I reboot the system everything seems ok. But suddenly it shows an error like
this,



 (none) login: /bin/sh: invalid options -n
Try '/bin/sh --help' fore more information
INIT : Id "x" respawning too fast:disabled for 5 minutes

I think some files corrupted. Are there any way to fix  the corrupted files?

I would download Parted Magic, make a CD and boot from it.

http://partedmagic.com/doku.php?id=downloads

The Linux CD installs into RAM and allows you to mount drives and, I
assume, copy or move directories. I found it useful for correcting
errors in fstab and creating directories as well as partitioning drives.

Good Luck.

No worries.  Use the Net install CD and boot the system.   On another
system in your LAN,  mount the DVD ISO and export it via either http
or ftp.  I believe NFS/CIFS export is also an option but I am not 100%
sure.

On the "install" system that you have booted with the Netinstall Cd,
choose ftp/http install and point it to the local ftp/http server you
have setup in above step.

The Netinstall method from a "local" server takes care of this issue.

virt-manager now has the ability to setup/manage bridges.  I belive that
came in one of the early redhat 6.0 updates and was not in the original
6.0 redhat release, so I can't say weather it's available in centos at
this time.

You really need to make the script do its own locking so it doesn't matter if 
cron runs it or a dozen web users click the 'run now' buttons at once.

incron sounds promising. I could use the regular cron to push a signal (ie. 
touch a file) at the regular interval, whereupon incron launches the

I don't know if this relates or not, but attempting to install FC15 in a
VM with only 512M of memory, fails: the kernel / installer hangs.  It
looks like the minimum memory requirements to install FC15 (and it looks
like RHel / CentOS 6 as well) is something greater than 512meg and probably
something closer to 1G.

the high end enterprise SSDs have supercaps to give them time to flush 
their write buffers to flash in case of power failure events.

but these drives are way more expensive than the $200 120GB stuff you'll 
find in the whitebox market.

the whitebox stuff has fast writes because they buffer them, but in case 
of power failure with pending write operations, all bets are off on your 
data integrity.

Re: [CentOS] Clearlooks & Bluecurve icons missing from Centos 6

[Gary Gatling]

Hello,

I started making my own gnome theme with some of these icons added back. 
But sadly its not ready to share with anyone yet. But since centos 6 is 
out I have a renewed incentive to hurry up and finish this theme for 
myself. (I worked on this with RHEL 6 up until now)

It is a noarch rpm. My theme is more grey then blue though. But it has 
the old icons... Like for nautilus folders and $HOME and stuff. I'm 
working on installing a couple of more centos 6 boxes tonight.

I don't think it would be too hard to rename what I have made as bluecurve 
or clearlooks even though its a modified default theme and mine isn't 
called that. The trashcan looks different because it has to be a vector 
drawing instead of a png... Mine is grey. When I finish it I will try to 
post a url to a repo for people who care about that.

Cheers,

Gary Gatling  | ITECS Systems

lI hope your SSD isn't write buffering on commits. many (most?) 
consumer priced SSDs can corrupt file systems badly on power failures 
during active file allocation operations, and drop pending database 
writes on the floor.

If an SSD doesn't do write buffering, its brutally slow relative to its

This was a few years ago, but IIRC, I just created a 
temporary directory under my Apache DocumentRoot, and then 
mounted the DVD iso image in my downloads directory, with 
something like this:

[root]# mount -v CentOS-5.5-i386-bin-DVD.iso /srv/www/centos-5.5 -o loop

Then from the machine I was going to do the http network 
install on, I used a web browser to check that I could get a 
directory listing of the DVD's contents, mounted under 
/srv/www/centos-5.5

Give Anaconda the IP address of the machine you want to 
install from, and the directory and then it does the rest I 
think.

Hi David. I seem to remember doing an http:// install using 
the net installer CD. I did it via my LAN from my main 
machine to an old laptop that could not read the DVD media.

Is that an option on the Centos net installer CD, and will 
that work for you?

I think you just need to copy the OS installation files in a 
directory under your Apache Document_root, and the installer 
just grabs the files via http.

[CentOS] Problem with net-install

[david]

Folks

I tried the net-install, because my computer has no DVD, only a CD.
The system has a USB connected keyboard, and it works just fine 
accessing the built-in BIOS.

However, when I booted the netinstall CD, the initial screen which 
asks for the type of installation did not respond to the keyboard.  I 
was therefore forced to wait the 30-seconds for the timeout, at which 
point the install screen showed up and the keyboard worked.

I fear that the net-install image may not support USB keyboards, 
which if so, is unfortunate.

The alternate of burning multiple CDs (as I've done with earlier 
versions) appears unavailable in CENTOS 6.

Furthermore, I was never given the choice of using a GUI or text 
install; I guess the old display device isn't supported in the 
install system.  Not being given any choices of packages during the 
install (a fact noted in the release notes) resulted, however, a 
system where a lot of the expected utility programs weren't there.:
   a)  "yum" worked
   b)  No SSH client appeared to exist, nor did YUM know about it.
   c)  Several useful utilities were not there, so they had to be 
installed via yum.

As a result, the process of bringing this system to a usable state 
consisted of:
   1)  Burn net-install CD
   2)  Answer the few questions.
   3)  For the net-install site, use 
http://mirror.centos.org/centos/6.0/os/i386
   4)  When it boots, use yum:
   yum install ftp perl unzip

It's possible--according to RH, it's streamlined and
simplified--accordingto everyone else, it's become a crippled thing.  
I know that there is no option for disk partitioning, and possibly no
option for custom package selection.

You may have to mount it, then copy all the files from it into another
directory--I seem to remember Fedora losing this ability 
awhile ago.  However, that's a vague memory and may be wrong.

I saw this in rhel 6 and newer fedora versions, the anaconda text 
installer comes with minimal options, to have full options you should 
use GUI or use kickstart.

[CentOS] 6.0 text-mode installer broken?

[Florin Andrei]

(I'm doing tests in a VirtualBox instance, so take this with a grain of 
salt.)

If you give the VM only 512 MB of RAM, the text-mode installer kicks in. 
It does not prompt you to configure anything related to the network or 
hostname. The system boots up without a network interface configured. 
Also, it won't let you choose the install mode, I guess it defaults to 
Minimal (which is fine by me, but still it's a bug).

If you give the VM 768 MB of RAM, the GUI installer is launched, and 
this one allows you to configure the hostname, the networking details, 
and choose the install mode. The system boots up with networking and all 
the niceties enabled.

Re: [CentOS] Installing from CD

[david]

Dear Gurus
Thanks for the responses.  I'll summarize what I've learned trying to 
install Centos6 on a Dell Optiplex GX 240

Review:
  a) I decried the lack of CD images for Centos6.
  b) I was informed that it's unlikely they'll be produced due to an 
upstream decision.
  c) I pointed out that the machine only had floppy, CD and HD boots 
capability.
  d) I got a suggestion to use the network method.

Results:
  1)  PXE boot might work, but it seems that it's a lot of trouble 
setting up a PXE server.  I'm still working on it.
  2)  The NET-INSTALL indeed did work, with the following gotchas:
2a) The URL to enter is not obvious.
2b) I tried the one at Stanford, and at uidaho, but they failed.
2c) Finally,
 http://mirror.centos.org/centos/6.0/os/i386worked.
  3) SInce I had only a text install, various interesting and 
important programs were missing:
ssh (which apparently is masquerading under the name 
"openssh-clients"), ftp and perl, which YUM got for me.

  4)  The module   perl-Digest-MD5  was not in the repository.  Was 
its removal intentional, or is it hiding in some other Centos6 repository?

  5)  The line-by-line notation during bootstrap is no longer 
shown.  This makes it difficult to detect where hangups occur during 
the bootstrap process.  Is there a way to display those notations in real time?

Conclusion:
   I'm still trying

I guess I'll have to do that as well.  I couldn't manage bridge network via the 
GUI anyway.  I might try installing NetworkManager and disabling NM control for 
the bridged devices, but for now it seems easier to just edit the files in 
/etc/sysconfig/network-scripts.

After all, they shouldn't be changing all that often on servers anyway...

Re: [CentOS] Updates... What? already?

[David Lemcoe]

Yeah, I did a yum update as soon as my install finished, and there were
288MB of updates. Alain was right, in that RHEL 6.1 security updates deemed
important enough made their way into the 6.0 repos. The centos.org site
explains it:

"Since upstream has a 6.1 version already released, we will be using a
Continous [sic] Release repository for 6.0 to bring all 6.1 and post 6.1
security updates to all 6.0 users, till such time as CentOS-6.1 is released
itself. "

Re: [CentOS] Installing from CD

[David Lemcoe]

I have an old server I just put 6.0 on (about 2 hours ago) and it only has
CD drive. a netinstall CD works just fine. If you have a decent network
connection, some time on your hands, or you want a minimal installation,
that's the way to go.

Correct Ljubomir. But most of the repo installation packages 
install both yum and smart config files. Smart calls them channels, 
and it's not hard to convert a yum repo file to a Smart 
channel file.

you can see my PHP script for doing this here:

http://forums.fedoraforum.org/showthread.php?t=211956

but it's virtually redundant now.

Upstream has deprecated anything but NetworkManager.  There is still 
system-config-network-tui and the regular config files.  At the moment, if you 
want GUI network config you're needing NetworkManager and friends.  That's an 
upstream decision, not a CentOS one.

The CentOS 6 announcement says that a Live CD (which will allow
installation) and a Minimal Install CD are on the way "within a few
days." I don't know for sure, but I think I remember that "Upstream"
decided to no longer support multiple CDs when they went to version 6
of their product. You'll no longer find CD sets of version 6 at
Scientific Linux either -- although they also have various Live and
Minimal CDs available.

Try using mrepo from RPMForge. All you need to do is to configure it and 
  let it do all the work. Yell if you need help configuring it.

[CentOS] CentOS 6 system-config-network missing

[Emmett Culley]

The network configuration GUI is not to be found on any of the CentOS repos or 
on EPEL.  I am not interested in having NetworkManager installed on a server.  
Is there an application that takes the place of system-config-network?

I wish I could, but this machine can boot only from a CD, a diskette 
or a HardDrive.  USB is not an option.

Am I stuck on Centos 5.x forever, or will the multi-CD images appear 
eventually?

Yo! I want to do exactly that -- shift a machine running SL

my tweaks nor my data. 

But I'm confused. Your advice : 

 I would strongly suggest something akin to yum reinstall \* and leave it 
to chug away (backups first naturally) for a while to refresh all the 
packages and teh rpm database to be in sync with the centos build. 
requires matching, same build options for sure etc etc

is Geek to me.what is "\*"? What rpm database? The one on my machine? 
What's in the repos? Or ? What are build options? (I don't do things 
like make and install, because I'm not competent to recover from bloopers

[CentOS] Hard disk installation

[Timothy Murphy]

Has anyone installed CentOS-6 from the hard disk?
I just tried this without success.

I should say that I asked the question before about CentOS-5.6,
and while I got many suggestions in reply,
no-one actually said that they _had_ installed CentOS this way.

What I did was to "mount -o loop" the DVD iso (which I checksum-ed)
and copy isolinux/vmlinuz and isolinux/initrd.img ,
as well as the images/ directory, to /boot ,
and then added a simple stanza

title CentOS-6
root (hd0,1)
kernel /vmlinuz text askmethod
initrd /initrd.img


The machine - I should have said that
it is an HP MicroServer -
boots fine, until it gets to
"Waiting for hardware to initialize",
at which point the screen goes blank
and nothing appears to happen.

I should say that the machine is running under CentOS-5.6,
which I installed with a USB stick.
I'm trying to install CentOS-6 on another partition.
I shall try the USB stick method shortly.

But I would be interested to know if anyone has actually installed
CentOS-6 from the hard disk, and if so how.

Re: [CentOS] CentOS 6 and pxeboot

[Phil Gardner]

FWIW, I have this problem with 5.6.

Are you installing from a local repo? If you are, try rsyncing the repo 
again. See if it changes the repodata files at all.

I have yet to find why my repodata files are changing for the main repo 
(I didn't build our original repo servers, there are a bunch of random 
scripts that run that were created by a previous admin), but re-syncing 
the repos seems to stop that error from popping up during a kickstart.

Hi Gary,

>From the release notes for CentOS 6.0:

The i386 DVD is just a bit too large to fit on normal single layer DVD+R 
media. It can be burnt succesfully on DVD-R. 

So if you have a DVD-R around.. try it!

According to clause 37.1.4.4 "User Configuration with Auto-Negotiation" of IEEE 
802.3-2008, auto-negotiation with 1000Base-X is optional, but encouraged.

In contrast, for 1000Base-T, we find the following information in clause 40.5.1:
"40.5.1 Support for Auto-Negotiation
All 1000BASE-T PHYs shall provide support for Auto-Negotiation (Clause 28) and

'Shall' being legal language for 'absolutely without a doubt must' in this 
case.  Overwise the PHY wouldn't be able to determine which PHY is the clock 
MASTER.

Because 6.0 is in fact 8 months old (from RHEL 6.0 release). I don't

Or stuck with >550m multimode fiber links (we have a few of those; longest is 
over 1km, and only multimode ran to that location).

The 10Mb/s standard is (heading from IEEE 802.3-2008):
16. Fiber optic passive star and medium attachment unit, type 10BASE-FP

802.3-2008 clause 41 provides for a half-duplex 1000Mb/s repeater, but it is 
noted that no maintenance changes are being accepted since May 2007 for that 
clause.

And then, of course, there are EPON and GPON, but that's passive full duplex 
using WDM technologies with the passive splitters and combiners (typical fiber 
to the premises gear).  GBIC's and SFP's are available for media converters and 
switches; if a GigE NIC has an SFP slot it might be possible to support those 
technologies at the workstation or server.

No, switching isn't mandated; while the 802.3 standard is pretty dense, it is 
now freely available from IEEE for anyone to download and look at.

I'd go for Smart Package Manager if it's available on Centos 
6?

On Centos 5.6 I'm running xfce4, which is reasonable.

Or even boot Parted Magic from the UBCD disk here:

http://www.ultimatebootcd.com/

New features in UBCD V5.0 include:

* New! The Linux-based distro Parted Magic is now 
included with UBCD V5.0. This should be the method of choice 
when you need to resize/rescue partitions, access NTFS 
filesystems or work with USB storage devices.

* New! UBCD V5.0 now supports both syslinux/isolinux and 
grub4dos. This helps improve the chances that UBCD will boot 
on any particular machine.

When you boot up from the CD, a text-based menu will be 
displayed, and you will be able to select the tool you want 
to run. The selected tool actually boots off a virtual 
floppy disk created in memory.

That will give you a full Linux desktop rescue system 
with nice GUI for mounting partitions, and also Midnight 
Commander for doing the stuff you want to.

Well worth the effort to download and burn to CD. It has 
100+ utilities for sysadmin and system setup/repair jobs.

HTH

No, but GUIs are important.  Don't you read distrowatch, and note how,
if a sytem doesn't have a GUI installer, the reviewer faults it?

My own impression, and it is nothing more than that, is that Fedora
being a testbed/devel platform, or whatever for RH has made it, in
certain ways, worry more about the desktop user---on the other hand, RH
with its reliance on GUIs, has also made me sometimes think it's more
for those who dislike Windows than those who like Unix, and the server,
et al, GUI-less installs were a pleasant surprise.  On the other hand, I
also wondered, cynic that I am, whether it was in part, influenced by
Ubuntu server, (which is also  sans GUI).

I'm afraid you missed the point I was making: I run CentOS at home, and
I'm not upgrading my own personal machine to 6 (it'll be 6.1), and that
will be semi-nervous-making, though not that bad, since I have separate
LVM partitions for things... and I hadn't done any of it here at work.

Actually, I'll be doing that this afternoon, and see how it goes.

[CentOS] centos 6 boot and install on hp dl380 G4

[Florian]

Hello List,

i downloaded centos6 x86_64. With DVD-iso1 i made a booteable usb-stick
(universal usb installer 1.8.5.7).
When i boot my HP ProLiant DL380 G4 from the stick, the CentOS boot
screen comes up and and the message
"Automatic boot in xx seconds..." appears.
* When i do not hit any key, the seconds are counted to zero an then it
starts again at 10 seconds - again and again.
* When hitting return, a boot menu appears:
 1) Boot
 2) Boot (text mode)
 3) Network Installation
 4) Memory-Test
 5) Boot from local drive
Only Options "Memory-Test" and "Boot from local drive" work.
When choosing Option 1,2,3 i'm always pushed back to the menu.

How to install CentOS vom the stick? Please help me to find my  mistake.
Please tell me, if i can provide any information.

Bye,
Florian

it was my understanding that 'hubs' were only supported on 10baseT and 
100baseT ethernets, and of course, have to be half duplex, and all 
devices have to be the same speed.   the so-called dual speed 10/100 
hubs were really a 10baseT hub and a 100baseT hub with a switch between 
them (and were really really awful).GigE mandates switching and full 
duplex.   Anyone using fiber for 10 or 100baseF is stuck in the last 
century.

You can make/get passive fiber hubs that act like old thinnet.  They aren't 
common, and I don't recall if any GigE ones exist.

You can actually make these if you have a fusion splicer with enough manual 
controllability.

So, yes, you can have a true CSMA/CD fiber hub, where the hub is a totally 
passive fiber device.

I recently got some quotes on some HP DL servers, the HP p410 w/ 1GB 
flash-backed cache (no batteries to replace ever) PN 572532-B21 was MSRP 
$750 before any corporate discounts.   this is a 8 channel 6gbps SAS 
controller (2 internal 4-channel connectors)

my configuration also came to about $6K/box but that was a mighty 
powerful box (25 2.5" SAS bays, 12 core 2.8Ghz 48GB ram, and said raid 
controller)

I stand corrected in that area. Tho, even upgrading to a LSI MegaRAID
9260 w/ BBU only brings you into the $1000 price range so unless
you're buying $1000 pizza boxes from Supermicro (not knocking the

Have you done this with CentOS/RH/OLE 6?  They've crippled it.  In a
marketing move that, again in my arrogant opinion, ranks up there with
Windows Genuine Advantage, they'll tell you that they've streamlined and
simplified it.   

I think the rationale was that they decided to put their efforts into a
GUI install and it was too much work to continue the functionality of
the text mode.  You'd have to dig through the Fedora testing list, I
think.  

However, kickstart functionality remains, so you can always use a
kickstart file, and that will enable you to do partitioning, and package
selection.

you want BBU (or flash-backed cache) if you want write-back cache, and 
not mandate write-through. This is quite independent of the RAID type.  
It greatly speeds up 'committed' random writes such as are generated by 
a transactional database.

Which is funny because Intel's SASUC8i (rebranded LSI3082E-R) is true

Date: Sun, 10 Jul 2011 19:51:21 +0100
From: Karanbir Singh 
Subject: [CentOS-announce] Release for CentOS-6.0 i386 and x86_64
To: CentOS Announcements List 
Message-ID: <4e19f4a9.1050...@centos.org>
Content-Type: text/plain; charset=ISO-8859-1; format=flowed

We are pleased to announce the immediate availability of CentOS-6.0 for 
i386 and x86_64 Architectures.

CentOS-6.0 is based on the upstream release EL 6.0 and includes packages 
from all variants. All upstream repositories have been combined into 
one, to make it easier for end users to work with.

There are some important changes to this release compared with the 
previous versions of CentOS and we highly recommend reading this 
announcement along with the Release Notes at 
http://wiki.centos.org/Manuals/ReleaseNotes/CentOS6.0

There are no CD images being released with CentOS-6, however we have 
some CD variants in the pipeline. Details for these are mentioned below.

Since upstream has a 6.1 version already released, we will be using a 
Continous Release repository for 6.0 to bring all 6.1 and post 6.1 
security updates to all 6.0 users, till such time as CentOS-6.1 is 
released itself. There will be more details about this posted within the 
next 48 hours.

+++
Upgrading from CentOS-4 or CentOS-5:

We recommend everyone run through a reinstall rather than attempt an 
inplace upgrade from CentOS-4 or CentOS-5

+++
LiveCD and LiveDVD

LiveCDs and LiveDVDs for i386 and x86_64 will be released within the 
next few days. These will bring in the ability to directly install from 
the livemedia.

+++
Minimal Install CD

We have also created a minimal install CD, that would bring up a base 
machine with just enough content to have a usable platform. This CD 
image will be released in the next few days.

+++
The LightWeightServer (LWS) CD

In order to bring back the CentOS-4 Server CD style single iso image, we 
are creating a LWS varient of the main distro. Details for this will be 
posted in the next few days with release happening after the live media 
and the minimal cd editions.

+++
Downloading CentOS-6.0 for new installs:

When possible, consider using torrents to run the downloads. In most 
cases you will find its also the fastest means to download the distro. 
There are currently over a thousand  people seeding CentOS-6 and it's 
possible to get upto 100mbps downloads via these torrents.

Torrent files for the DVD's are avilable at :
http://mirror.centos.org/centos/6.0/isos/i386/CentOS-6.0-i386-bin-DVD.torrent
http://mirror.centos.org/centos/6.0/isos/x86_64/CentOS-6.0-x86_64-bin-DVD.torrent

You can also use a mirror close to you :
http://www.centos.org/modules/tinycontent/index.php?id=30

Most mirrors will allow direct DVD downloads over http, ftp and rsync.

Please keep in mind that not all mirrors are currently updated, some 
might take upto another 24 hours before they have all the content.

Sources and Debuginfo packages:

SRPMS and debuginfo packages are still making their way to the CentOS 
mirrors and should be available within the next 24 to 48 hours. We are 
prioritising the centos modified packages.

+++
Getting Help:

The best place to start when looking for help with CentOS is at the wiki 
( http://wiki.centos.org/GettingHelp ) which lists various options and 
communities who might be able to help. If you think there is a bug in 
the system, do report it at http://bugs.centos.org/ - but keep in mind 
that the bugs system is *not* a support mechanism.

+++
Contributing and joining the project:

We are always looking for people to join and help with various things in 
the project. If you are keen to help out a good place to start is the 
wiki page at http://wiki.centos.org/Co

Huh? I always use the text-based install, and check the select packages
(or whatever it is) box, and the next screen's where I go down its list,
and go into each, and (un)select what I want on the machine.

I regularly run ssh -X server, and run firefox remotely.

I agree. However, in those situations, I typically run these apps headless 
using X forwarding over SSH.

What caught me out (_doesn't_ sounds like it did you though), was that the 
CentOS 6 x86_64 installer chose to do a text-based
install, through lack of support for the graphics card, I guess (this is inside 
VMware Server 1.0!).  The text-based install does
not give you a choice of the kind of stuff to install, you just seem to get 
'minimal'.

I had much better luck after reading through the install guide (here:
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Installation_Guide/index.html
 ).  Booted off the iso, hit 
and then at the boot prompt: linux vnc.  I could then use a VNC client to do 
the nice graphical install.

that is an Intel ICH10 SATA controller, which is purely JBOD hardware, 
it supports Intel's 'Matrix' fake-raid.

I highly recommend you use it in AHCI mode (thats a BIOS setting) and 
configure raid in linux with mdraid

If you want harwdare raid in a DL180G6, you should have gotten one of 
the optional 'real' raid controllers such as the P410i w 1gb flash 
writeback cache.

I have to agree with Scott.

A "lightweight" server option is a
long-awaited-and-much-deserved-feature but it would be nice if we
could still get a very lightweight X - even if it doesn't run
automatically. I often need to use X for odd stuff which only works on
X - like using Firefox to check if a specific feature on a website,
hosted on the server works fine. Or like using gparted to get the
extra features which fdisk doesn't offer.

Just a thought...

If I'm not mistaken, (not making fun of Emmanuel, just the same caveat),
neither server nor web server have a GUI by default.  IMLTHO (less than
humble) this is something they should have done a long time ago, (though
I would like to see either flux or openbox available as alternative--on
the other hand, that's purely personal preference, and can be safely
ignored--just, if I do, for whatever reason, want a GUI on a server, I'd
much prefer a *box (or other--twm is available actually, but I don't
like it), I'd like something light.

Hi,

Thanks everyone, yes server has no GUI by default, so should have added a 
install time, now working by adding later

Thanks

If I'm not mistaken, the "Server" option does not include the GUI so
you'll have to install the GUI group manually as others have
suggested.

Try discarding the array and rebuilding, perhaps using a different RAID level, 
see if that makes any difference. I have vaguely similar machines and have 
not encountered this type of problem, and I'm pretty sure all this range are 
certified for RHEL.
