Re: [CentOS-virt] Cannot remove lvs associated with deleted vm guests

2012-01-30 Thread James B. Byrne

This problem was finally resolved with the generous help
of Bryn M. Reeves on the inux-...@redhat.com list.

The difficulty was that the utility kpartx had the lvs
opened via their mappings.  Further, the mappings were
created with the -pp option of kpartx and that option had
to be provided to the delete action in order for that to
work:

# kpartx -d -pp /path/to/logical/volume/name

Once the mappings were removed then the lvremove also
worked and the volumes were removed.

A small point, failure to provide the -pp option to the
kpartx -d action does not raise an error.  Nor does it
remove the mapping however.

Despues de unos dias testeando creo que kvm+qemu és una gran herramienta de
virtualizacion. Vaya, de momento me parece muy buena.
He provado algunas mas proxmod, virtualbox y vmware y de momento me gusta

El unico problema es que para algunas acciones es necesario emplear la
consola. Però bueno, gracias a Maykel Franco ( esta en esta lista) he
conocido una buena herramienta de gestion de guest. Esta herramienta es el

[CentOS] CentOS 6.2 KDE desktop with KDM - need guidance

2012-01-30 Thread Arun Khan
I want a CentOS 62 (amd64) KDE desktop with KDM as the GUI login manager.

My system environment is as follows:
Host OS: openSUSE 11.4 .(amd64) with VirtualBox (64 bit)
GuestOS: CentOS 6.2 (amd64)  10GB virtual disk

I chose the Customize Now option in the installer and chose KDE
group w/o the Desktop group.   The system boots to a CLI console.  I
can login and see that the KDE rpms including kdm are installed but
startx gives no joy [1].

I figured that the Desktop group is required so chose it in the 2nd
try.  This time system boots with the GDM login manager; I can choose
a GNOME or a KDE desktop from the GDM.

Searched around but could not find the GUI switcher applet to switch
from GNOME to KDE.

Tried the method in this link (albeit it is for 5.x)
http://www.centos.org/docs/5/html/5.1/Deployment_Guide/s2-sysconfig-desktop.html

In 6.2 the file /etc/sysconfig/desktop does *not* exist, so I
created it with the two variables - still no joy.

Finally, I hacked the script /etc/X11/prefdm and changed the order
of the two lines in the Fallback to put kdm before gdm as shown below.

code
 snip 
[ -n $preferred ]  exec $preferred $@ /dev/null 21 /dev/null

# Fallbacks, in order
# order of GDM/KDM lines, changed by akk to initialize KDM
exec kdm $@ /dev/null 21 /dev/null
exec gdm $@ /dev/null 21 /dev/null

 snip 
/code

With above change I am getting a KDM login manager.

To be noted that line [ -n $preferred ]  exec $preferred  ...
does not work since my preference is KDE/KDM (it should have
initialized to KDM) but instead it goes into the Fallback section
wherein gdm (the original Display Manager) is initialized irrespective
of what is in /etc/sysconfig/desktop.

Although, I have achieved my objective with this hack, I think I am
missing something (a CLI/GUI utility) which would have allowed me to
change to KDM w/o hacking the script.

Also, I noticed that the KDE menus did not list any item to
install/remove and update the software packages on the system.  I

Are the gtk apps. Add/Remove Software and Software Update the only
tools for this tasks?

I need a minimalist KDE desktop environment with the minimum of gtk
libs and GNOME apps.

Thanks for any guidance/pointers to be able do so.

[1] The installer should have automatically selected the Desktop
group if it is essential for a graphical desktop.

TIA

[CentOS] confidence in partitioning tool (6.2)

2012-01-30 Thread Larry Martell
I have a Windows 7 laptop that I want to make dual boot with CentOS
6.2. My plan was to use the Windows Disk Management tool to partition
the disk, but I do not have the needed admin rights on the box to use
that. Has anyone used the partitioning tool that comes with 6.2 to do
this? Can I have some level of confidence that it will not mess things
up so that I cannot boot into Windows? if it screws up and makes
Windows unbootable that would be a Very Bad Thing.

Thanks!

First make backup of the MBR (some Linux software save them elsewhere on 
the disk.)

I used CentOS 6.2 DVD to partition Windows 7 partitons, amongst all 
others. But take notice that regular CentOS DVD/LiveDVD has no ntfs 
support so you will not be able to format them with NTFS. You can 
however create them as FAT32 and re-format them from windows.

CentOS 6.2 DVD can also align partitions for new 4k sector HDD's

If you have space somewhere to save a backup, you can boot a
clonezilla-live CD and do a disk-image copy that will save your
current partitioning and content.  It can connect to the image storage
via nfs, windows file sharing, or ssh, and it knows enough about most

Two things: on the one hand, you're familiar with the std. instructions to
use Windows' defragger before you resize the partitions, correct?

 First make backup of the MBR (some Linux software save them elsewhere on
 the disk.)

OK, I'll research how to do that and give it a shot.

 I used CentOS 6.2 DVD to partition Windows 7 partitons, amongst all
 others. But take notice that regular CentOS DVD/LiveDVD has no ntfs
 support so you will not be able to format them with NTFS. You can
 however create them as FAT32 and re-format them from windows.

 CentOS 6.2 DVD can also align partitions for new 4k sector HDD's

Not sure that either of these things will be an issue to me.

No, I'm really not familiar with anything in Windows. I've managed to
have a 30 year career in software development without ever spending
very much time on Windows.

This machine was given to me by a client, and I was asked to set up
the dual boot with CentOS. I asked for admin rights under Windows, but
I was told it was against corporate policy to grant them to me. I told
them I was hesitant to try this without first partitioning the disk
under Windows, as I did not want to render it unbootable. They said
they didn't care if that happened, and if it did, just send it back to
them and they'd reinstall Windows (don't ya just love that corporate
mentality ;-)  But that will be a pain, and without the machine I
cannot VPN into their network and get my email and do other things I
need to do.

 No, I don't think there's space for that.

The space could be on just about any drive - local/external or
anywhere you have network write access.  It's not likely you will
break things with the CentOS installer, but backups are always a good
thing.

As someone else mentioned, VMware is also a good alternative and has
the advantage that you don't have to stop running windows to boot
Linux.   I think VMware Player is the free version instead of
workstation, though, unless something has changed recently.  But
Player is now capable of creating VMs so it is suitable for that kind
of use.  With a little extra work you can combine a dual-boot with
VMware Player so you can run it either way - my own laptap is set up
that way, but I've forgotten the exact details.

[CentOS] mod_rails under Apache under Ceontos 6

Hello listmates,

For some reason we don't seem to be able to launch a Ruby-on-rails
application ( http://www.redmine.org/ ) on a CentOS 6 machine under Apache.
Nor can I find a mod_rails as a separate package for it. Would anyone have
any idea what we might be doing wrong?

Thanks.

[CentOS] One of my servers wont boot today

2012-01-30 Thread Jason T. Slack-Moehrle
Hi All,

One of my servers upon a restart today comes up with an error 

checking filesystems:

fsck.ext3: no such file or directory while trying to open 
/dev/VolGroup-1/Logvol00.

/dev/VolGroup-1/LogVol00. The superblock could not be read or does not describe 
a correct ext2 filesystem. If the device is valid and it really contains an 
ext2 filesystem (and not swap or ufs or something else), then the superblock is 
corrupt, and you might try running e2fsck with an alternate superblock: e2fsck 
-b 8193 device

I dropped into the shell and tried mounting:

mount -t ext3 /dev/VolGroup-1/LogVol00 

I tried booting to media and do 'linux rescue' but it could not mount file 
filesystems either and nothing at all ends up in /mnt/sysimage.

I think this was caused by installing quotas and changing /etc/fstab to add 
,usrquota,grpquota.

There are 2 x 1tb drives, software raid, mirrored.

Can anyone provide advice on how to solve? I would think if I could get 
/etc/fstab edited back to normal I would be all set.

mod rails is 'passenger' which is typically installed as a gem and then 
finished by executing the bind code (as root)

gem install passenger
passenger-install-apache2-module

but CentOS 6 might have a package that does this but it is certain to be out of 
date at any given time which makes the gem more suitable.

well, a few differences: if you run a VM you won't be needing to load any

Can't help there - I did mine long ago, probably with a Knoppix or

Then you may need to mount it in some created folder (mkdir -p

Check if your system had any updates (kernel in particular) between

the most reliable method for us has been to pre-partition the drive into at

My suggestion, and I am assuming you are not very proficient with Linux 
partition/backup tools . So, download Hiren's Boot, go to Windows XP 
environment and create ghost image of the entire disk. You should be 
able to do it with DriveXML app. Reserve solution is DOS mode and 
running some other backup app. Make sure you also backup MBR.

Make sure created backup is safe on some external storage.

Some backup apps are outdated for W7 NTFS, but Hiren's will warn you if 
you choose such app.

P.S. Hiren's CD also has Linux mode, with Parted and few backup apps, 
for linux.

If you need to resize NTFS partition, do it from Windows/DOS app from 
Hiren's Boot. Linux without NTFS support will not be ableto do it, and 
even with support I would avoid such solution. That same App can create 
free space you need for CentOS and boot partition.
Linux boot partition must be one of the primary partitions (first 3 if I 
recall correctly), so create a boot partition (best size is  500 Mb, 
just to be on the safe side and have root for the future. absolute 
minimum is 200MB in my opinion). Then you can create Extended partitons. 
Even Win7 now uses separate ~100MB sized partition and other partitions 
can be Extended ones.

P.S. I also like to create Windows swap partition and move sap file 
there, for smaller fragmentation of the file system.

[CentOS] Quantum scalar i40 tape partitions

2012-01-30 Thread Xinhuan Zheng
Hi All,

I have a Quantum scalar i40 tape library. I need to configure it to TWO tape 
partition libraries, e.g., library_a and library_b, so that each library has 
its own tape drive. Then connect this physical tape library to two different 
CentOS servers so that each server can see its own media changer and tape 
drive. I once had a successful configuration on one host but NOT on the other. 
One host sees the media changer and one tape drive, while the other host only 
sees the tape drive. After I delete tape partitions and re-create them both 
servers are totally screwed up. This is CentOS 5.7 kernel 2.6.18-274.

You can Ghost the partition with the software that allows to reduce the

[CentOS] lm_sensors

2012-01-30 Thread Fajar Priyanto
Hi all :)
Using lm_sensors, I can see few temperature indicator.

M/B Temp:+39°C  (low  =   +15°C, high =   +40°C)   sensor = thermistor
CPU Temp:+33°C  (low  =   +15°C, high =   +45°C)   sensor = thermistor
Temp3:   +53°C  (low  =   +15°C, high =   +45°C)   sensor = diode

What is that Temp3? It's the hottest.
Which one is the best to use if I want to use lm_sensor as a general
indicator of my server room temperature?
(my request to buy a Mini Goose temperature monitor is still pending).

Thank you.

Yes, that works with Ghost, if you have space for the image copy.  Are
there any free tools that know how to shrink an NTFS image on the fly

I usually use Acronis TrueImage ($$) to do this for Windows NTFS 
volumes.make a partition image on a seperate device, then delete and 
repartition the disk into whatever you want, then restore that partition 
image to the resized volume.note that in TrueImage (and in Ghost), a 
'partition image' is more like a exfs 'dump', its really a file by file 
backup, done at the NTFS equivalent of an inode level.


I strongly dislike and distrust any tool that attempts to do in-place 
partition resizing, the results are rarely optimal and if anything goes 
wrong, you lose the whole mess.   With the image, repartition, restore 
technique, every step is restartable and you have a full backup.

I did  vgchange -a y VolGroup00

and it activated 3 volumes

So I am trying to fsck and it comes up with the same super block error I had 
but I dont see how to fix it.

It says:

/dev/VolGroup00/. The superblock could not be read or does not describe a 
correct ext2 filesystem. If the device is valid and it really contains an ext2 
filesystem (and not swap or ufs or something else), then the superblock is 
corrupt, and you might try running e2fsck with an alternate superblock: e2fsck 
-b 8193 device

So I tried e2fsck -b 8193 /dev/VolGroup00 

and it seems I get the same error coming up over and over

I tried:

fsck -y b=8193 /dev/VolGroup00 as well

Any thoughts?

 ah, ok. so you need to get centos working on the bare-metal hardware of the
 laptop. VMs will not help you there ;)

 I didn't come here to debate VM's. I was just looking for someone to
 say Yeah, I used the CentOS partitioning it and it worked like a
 charm or I used it and it was a disaster.


 sorry if i sounded cross; i am not trying to be argumentative.

No problem. The discussion was just veering away from what I was
trying get out of it.

 it's just
 that from my experience dual-booting has not been worth the effort unless
 it is truly needed for the hardware performance, and running CentOS on a
 laptop (depending on the model) may prove challenging to get all the
 hardware to work.

 as for partitioning, i have not had success using any linux installer to
 resize an existing Windows partition. supposedly gparted on a livecd can do
 this (though it has not worked for me when i tried it, possibly because i
 didn't defrag windows first):
 http://www.micahcarrick.com/resize-ntfs-partition.html

 the most reliable method for us has been to pre-partition the drive into at
 least 2 partitions, then install windows into the first partition, then
 install centos (letting it use the free space to auto-create partitions for
 /boot and LVM, and correctly set up grub in the MBR.)

I can't install Windows - I don't have the disks, and this is a
corporate install with all sorts of their own stuff.

So my plan is to defrag as Mark suggested, use clonezilla as Les
suggested, and back up the MBR as Ljubomir suggested, then give it go
with the CentOS partitioning tool. Thanks much everyone for the help!
I'll let you know how it goes.

You need to fsck each logical volume, not the whole volume group, e.g.

e2fsck -b 8193 /dev/VolGroup00/LogVol01

or whatever.  
Look under /dev/VolGroup00 to see what's there.

 This is a new system, but yes, it will be deployed on laptops running CentOS.


 My suggestion, and I am assuming you are not very proficient with Linux
 partition/backup tools .

The last time I did that was in 2003 - I was installing Mandrake on an
XP system that I had admin on, and I used Partition Magic to partition
the disk. Since then I've been working on Mac's, Solaris, and RHEL
systems that someone else was administrating.

 So, download Hiren's Boot, go to Windows XP
 environment and create ghost image of the entire disk. You should be
 able to do it with DriveXML app. Reserve solution is DOS mode and
 running some other backup app. Make sure you also backup MBR.

 Make sure created backup is safe on some external storage.

 Some backup apps are outdated for W7 NTFS, but Hiren's will warn you if
 you choose such app.

 P.S. Hiren's CD also has Linux mode, with Parted and few backup apps,
 for linux.

 If you need to resize NTFS partition, do it from Windows/DOS app from
 Hiren's Boot. Linux without NTFS support will not be ableto do it, and
 even with support I would avoid such solution. That same App can create
 free space you need for CentOS and boot partition.
 Linux boot partition must be one of the primary partitions (first 3 if I
 recall correctly), so create a boot partition (best size is  500 Mb,
 just to be on the safe side and have root for the future. absolute
 minimum is 200MB in my opinion). Then you can create Extended partitons.
 Even Win7 now uses separate ~100MB sized partition and other partitions
 can be Extended ones.

 P.S. I also like to create Windows swap partition and move sap file
 there, for smaller fragmentation of the file system.

Thanks much for the pointers!

http://www.hirensbootcd.org/download/ , even though I'm not convinced 
that all the programs on the CD can be freely redistributed.

Then boot from the System Rescue CD, start X, and use GParted to resize 
the Windows partition, making it smaller and creating free space for 
CentOS. Then reboot from the CentOS installation DVD, making sure to 
create a custom partition layout so as to create a new Linux partition 
in the space you freed up.

 Maybe a little different answer than you're looking for

 But why not install VMware Workstation (free)?

 Unless there's some specific reason,

The OP does not have admin rights to the Windows OS.  I presume he
would need it to install any piece of software (I use Virtual Box).

In a way it is good that you don't have admin access for Windows 7
(which BTW can be solved with many of the system rescue CDs out
there).

On one install of Windows 7, the partition manager of the Windows 7
installer left a gap of about 70MB in the middle of it's 100MB admin
partition and the main C: partition.  I  don't know the rationale
behind it but there was a 70MB of disk space of not much practical use
to anybody.Some may argue that 70MB may be small change in a 500GB
disk but to me it is 70MB of wasted space that could be part of some
other partition.

Use it at your own risk.

I realigned the partitions with Gparted.  Windows 7 complained the FS
needed to repaired.  I popped in the Win 7 DVD, repaired it's FS and
it booted fine.

Oh, yes, I wanted to mention this: don't ask GParted to align the

You might try

Then from this output - if you can get any - use one of the backup
superblocks with

#e2fsck -b number from above output /dev/VolGroup00/logical volume

Re: [CentOS] One of my servers wont boot today

2012-01-30 Thread Paul (GPR Support)
Another possible way of getting backup superblock info is with

# mke2fs -n /dev/your device

And then use this with

#e2fsck -b backup block /dev/your device

mke2fs with the -n switch, runs as though it would create a new filesystem
without actually writing anything to disk. So it tells you where it would
put the backup superblocks if it were to run in full filesystem creation
mode. This means that if you use different parameters from the ones used in
actually creating the file system to begin with, you may get the wrong
backup superblock info. Nothing should break by doing this anyway.
