Dear centos community, I was in the process of loading the latest 5.5 release of centos in a VMWARE ESX 4.1 host as my first virtual machine, suddenly while booting I got a panic error with the following on screen. Can someone point me in the right direction. This machine has 24 cores and I allocated 1 for Centos to use with 1024MB of memory. Any clues or workaround to solve this problem? Thank you in advance.

Tru, you nailed it right. I will load Ubuntu and Debian and will report back, this may be a bug in the loading process. I did install this system with Centos by itself and it load ok, but the virtual machine its not loading and it just keep crashing with the same error as the bug you provided/posted. Maybe someone can shine some light on this. Thank you.>>> Tru Huynh 12/17/10 6:47 PM >>>On Fri, Dec 17, 2010 at 06:23:52PM -0500, Lisandro Grullon wrote:> Dear centos community, > I was in the process of loading the latest 5.5 release of centos in a VMWARE ESX 4.1 host as my first virtual machine, suddenly while booting I got a panic error with the following on screen.

Tru, looks like a bug in centos, I just loaded RHEL 6 without any issues. I dont think it has something to do with the actual image file, but in any case maybe I should re-download the entire DVD again just to make sure.

As stated in the KB articles quoted in the bug report: https://access.redhat.com/kb/docs/DOC-31516 https://access.redhat.com/kb/docs/DOC-38013 the patch is in the kernel-2.6.18-194.3.1 and onward. CentOS/RHEL 5.5 comes with kernel-2.6.18-194 which has the bug. RHEL-6's kernel is much newer at 2.6.32-71, so it does not have this bug. Therefore to get around this issue, as suggested in one of the KB articles, you first install CentOS *5.4* and then update it to the current kernel thus skipping the problematic kernel. Akemi
Akemi, I went through the different mirrors and was unable to locate the ISO as it is stated as deprecated or unsupported, is there any plans to fix this issue in 5.6 or rather 6.x release. It appears that the latest build from Centos was built back in may, lots of bugs have emerge since them including this one relating to a kernel panic. Please advise in the location of 5.4, i am willing to try it.>>> Akemi Yagi 12/17/10 7:56 PM >>>On Fri, Dec 17, 2010 at 4:26 PM, Lisandro Grullon wrote:> Tru, looks like a bug in centos, I just loaded RHEL 6 without any issues.

Akemi, Why is the vault download like a snail, I usually download 2-3MB/s from the mirrors, but this one your provide only getting 12-15Kbps.

This was very helpful Akemi...I was loading centos in two other identical servers today and was having such a hard time loading it from DVD, DVD appears to be crashing, I even re-downloaded the image 3 times from three different mirrors and burn them with different applications (Nero, Roxio, and poweriso), worse case scenario it must be something with the Memorex DVD Media. Anyway, after two hours of trying I decided to do a network install and everything went flawless. Good to have many options, Centos rocks!>>> Akemi Yagi 12/17/10 8:13 PM >>>On Fri, Dec 17, 2010 at 5:11 PM, Lisandro Grullon wrote:> Akemi, > I went through the different mirrors and was unable to locate the ISO as it > is stated as deprecated or unsupported, is there any plans to fix this issue > in 5.6 or rather 6.x release.

I downloaded a bunch of times from different mirrors and instead of burning to CD, I loaded the CD to a USB key. After the first downloaded image failed, and after downloading others, I did an MD5 checksum on all of them, and sure enough, none of them checked out. Errors did not exist in consistent places. I too fell back to netinstall with a kickstart script, so all went well in the end, but I find it's odd that both CD and DVD downloads from different mirrors did not transfer correctly (?) . What could be going on? Rob

I have had very bad experiences with Memorex tapes, floppies and CDs over the years. I won't use them any more. There is also a Euro brand with a similar track record for me that I wlil no longer use either, but I can't remember the name at the moment.

Hi,
When I make DVDs of Centos and any others for that matter, I take the
following steps:
1. Find an official torrent if possible. (Centos has torrents for the
DVD. Unfortunately no Jigdo so far as I know.)
1.1 Torrents come with checksums and the torrent app I use will check
the downloaded file against the checksums. Otherwise find a stable
mirror close to where you are for better speed.
1.2 If you cant get a torrent find out if the distro vendors offer any
other options. IE: Jigdo, zsync etc. etc. I usually try for one of
these before going for a strait FTP download. FTP downloads often fail
and are not always recoverable in the event of an interruption. Jigdo
is my favourite as each and every package and file is downloaded and
verified and then the DVD image (.iso) made up from all the packages.
It is basically a self checking system and has proven to be very reliable.
2. Once the file is downloaded do a binary checksum using the official
checksums found on the vendors homepage or mirror you downloaded from.
Information on how to call sha512sum or any checksum tool to make it do
a binary level checksum can be found in the man pages. (sha512sum -b
filename.iso)
I always go for the largest checksum algorithm provided. IE: SHA512SUM
if available otherwise SHA256SUM, SHA1SUM or as a last resort MD5SUM.
If this passes proceed to step 3.
3. Burning the DVD. This step is the trickiest part to get right.
3.1. Find **reliable** media. Always choose DVD-R. Go with a named
brand. I usually go for spindles of 50 or less. I have found that the
100 unit spindles get a bit heavy on the ones at the bottom and I am
unsure of the effect shipping and handling has on them.
3.2. Use the following wodim command:
"/usr/bin/wodim dev=/dev/sr0 driveropts=burnfree fs=14M speed=4 -dao
${ISO_FILENAME}" where /dev/sr0 is your DVD device and ${ISO_FILENAME}
is your iso you are trying to burn.
to burn the DVD at the slowest possible speed your DVD burner will go
for. Use DISK AT ONCE (dao) to write the whole file in one go. Wodim
will close the disk session after burning. I know nothing about using
windows tools to burn DVDs as I do this on Linux.
4. Check the media against the official checksum you used in step 2.
Here are my steps for doing this. Again this has to be done right.
Sometimes you will get different results if you try to simply call
sha512sum -b /dev/sr0 where /dev/sr0 is your DVD drive.
4.1. Use the isoinfo tool to retreive the blocksize and blockcount of
the DVD you are checking. (/usr/bin/isoinfo -d -i /dev/sr0 where
/dev/sr0 is your DVD device.)
4.2. Use dd to read the disk using the correct blocksize and blockcount
settings and pipe through the checksum tool.
IE: "/bin/dd if=/dev/sr0 bs=${blocksize} count=${blockcount}
conv=notrunc,noerror status=noxfer | sha512sum -b" where ${blocksize}
and ${blockcount} are the numbers you retrieved from using isoinfo.
conv=notrunc,noerror come from another post I found once. So far so
good... The dd man page explains that notrunc means do not truncate the
output file and noerror means continue after read errors.
status=noxfer is just to keep the whole thing a little quieter by not
displaying transfer statistics. You can play with these settings if you
like. They have done me fine for over 400 burns since I started doing
this over 2 years ago.
This will produce a checksum you can visually compare with the official
checksum you retrieved from the mirrors to confirm if your disk is good.
I do not know of a better way, without actually installing the OS, of
verifying that the media is good.
I have all this scripted so complete all these steps every time I ship a
DVD to any customer who orders one.
Best regards
David Latham

Don't know too many places outside of their community > using it. It seems to be a cross between bittorrent and rsync...Except for Fedora (for example) which is a Redhat project and Centos is a Redhat clone so it can't be only Debian. I know a developer debian started for debian and it works very well for debian due to their package naming conventions, but other distros are picking it up. Its far better than bitrorrent or rsync in that jigdo downloads the individual packages and then makes the iso images from these packages. This means that every package and file on the iso image is verified at the point of download allowing for a much safer download. Also, it is possible to mount an existing ISO and tell jigdo about this mount so that any packages which are duplicated exactly in the new iso do NOT need to be downloaded again. This is handy in Fedora for example when one wants to create the CD Set after already having downloaded the DVD. Why download the same thing twice. In my experience, the DVD provides all 6 CDs and approximately 10 small files are needed to be downloaded to complete the whole CD set. Here is the link to the Fedora all formats page showing the jigdo option nicely highlighted. http://fedoraproject.org/en/get-fedora-all Regards David Latham www.thelinuxcdstore.com
