the SmartArray 110i is simply Intel "Matrix" fake raid.  The hardware is 
purely basic plain SATA JBOD, but the BIOS and driver implement the raid 
behind the systems back.

Configure the BIOS for AHCI native SATA, and use linux native raid.  See

[CentOS] Kernel panic - not syncing: Attempted to kill init! after installation of Driver Diskette for enabling Onboard RAID Controller Chipset

[Kaushal Shriyan]

Hi,

I have HP DL 180 G6 2U Rack Server with HP Smart Array Controller Card
B110i Onboard SATA Controller Chipset. This server has 4 * 500 GB SATA
HDD have configured RAID 1+0 and it shows Single Logical Drive of 940
GB Hard Disk in the RAID BIOS. Have created driver diskette using dd
command to enable this controller card to the CentOS 5.6 x86_64 arch
and it shows HP LOGICAL VOLUME of size 940 GB by the Anaconda
installer to load CentOS 5.6 on these server.

Below are the steps to enable driver diskette from HP
(http://h2.www2.hp.com/bizsupport/TechSupport/SoftwareDescription.jsp?swItem=MTX-253be2baaf684954a55b6680ad&lang=en&cc=us&idx=1&mode=4&;)

gunzip hpahcisr-1.2.6-7.rhel5.x86_64.dd.gz
dd if=hpahcisr-1.2.6-7.rhel5.x86_64.dd of=/dev/sdb (USB Flash Drive)

CentOS 5.6 Installation Procedure :- Boot up the System using DVD
containing CentOS 5.6 and type linux dd blacklist=ahci and then it
asks for load driver diskette and then point it to the USB Flash Drive
which contains the SATA Controller driver image. The driver gets
loaded during the installation and after OS Installation is complete
and then reboot it fails and says "Error 21: Selected disk does not
exist" and when i edit grub grub> root (hd0,0) and press b to boot it
works fine and later I get the below message on the Console with
Kernel Panic.

Mounting root filesystem.

All 3 DVD-s (2 x x86_64 + i386) are burned on K3B 0.12.17 on CentOS 5.6.

x86_64 is tested and works. i386 not yet tested but it passed K3B 
verification.

My successful burns (although not tried with CentOS 6 yet) have been
using growisofs directly:

  growisofs -speed=1 -dvd-compat -Z /dev/dvd=image.iso

I used K3B in Fedora 15 to burn the DVD image.  I changed the speed to
1x, but K3B reported the burn speed as 2.4x - I guess it couldn't go any
lower.

The newly burnt image didn't boot either.  The error was the same.

So sad. :(

The burner I'm using is a built in laptop drive. :/  However, I have
used it to burn LinuxMCE DVD images, and those have always booted on my
new machine without issue.

I think it's something specific to CentOS 6 and the particular hardware
I'm using.

Can you read other discs burned by that burner in the server machine?  I 
understand that it has a DVD/CD burner, but is a CDRW burner?  Can you 
attach this drive to a USB cable or move it to the affected machine to see 
if the problem follows the drive or the machine?

The drive in my little server is a DVD/CD burner, too.  So, that's not

By any chance is the drive that does not work *NOT* a CDRW drive? 
Sometimes CD-ROM drives do not like reading rewriteable media.

planning on about 5-10% hot spares in the array.   For example, my 
suggested layout for 192 disks is...

18 x 10 drive raid6, with 12 hot spares.   The 18 seperate raid sets 
would be merged into larger volume groups, probably as volume sets and 
NOT stripes so the idle disks could spin down, since most of this data, 
once written, will rarely if ever be looked at again.   With 3TB disks, 
this gives 18 x 8 x 3 TB == 432TB total usable capacity (really more 
like 400TB when you figure binary vs decimal, etc etc)

> What kind of discs and controllers do you intend on using?

Seagate Constellation ES.2 3TB SAS drives, in (one of a couple major 
label vendors) SAS chassis, with (major vendors' rebranded) LSI SAS 
HBA's (configured for JBOD).   Using SAS disks rather than SATA to gain 
the path redundancy from dual porting.

with newer hardware, decent quality blank media, and current generation 
'16X' and '20X' burners, I find burning DVDs at 8X, which is the max CLV 
speed, gives me a very high level of player compatibility.   Better yet, 
it doesn't take hardly any longer than the 'full speed' burn.   faster 
than 8X, the drives use CAV mode where the burn speed goes up on the 
outer part of the disk, which makes the last 20 or 25% of a full disk 
much more prone to errors.

btw, I've found current generation Samsung fullsized SATA & ATAPI(IDE) 
burners to be very reliable and highly compatible with a wide range of 
playback gear.

My experience is, some players/readers prefer the DVD-R, others prefer 
the DVD+R, but most anything newer than first generation ancient DVD 
doesn't care.   DVD-R has slightly more capacity which is important 
here.   I think the differennce in reliability is a red herring.

And make sure the assembler wires it all up correctly, I have a JBOD box, 16 
drives in a supermicro chassis,
where the drives are numbered left to right, but the error lights assume top to 
bottom.

The first time we had a drive fail, I opened the RAID management software, 
clicked "Blink Light" on the failed drive,
pulled the unit that was flashing, and toasted the array. (Of course, NOW it's 
RAID6 with hot spare so that won't happen anymore..)

Oh, and one more thing.. if you're going to use that many JBODs,

I suppose it depends on which option you prefer :)


But, I think if your crontab has many lines then it's a bit easier to
use the method I suggested.


For example:

MAILTO="root"
line1
line2
line3
.
.
line9


MAILTO="support-dept"
line10
line11
line12
..
..
line13
line14



MAILTO=""
line15
line16
etc

Why not simply do one of the following:

30 6 * * * /path/to/job 2>&1 | mail -s " output" user at domain
.com

Or

Within the script that runs the job, send the output of the to a file,
then cat the contents of the file through

mail -s " output" user at domain.com

Hello Devin. I heard that about audio CD's as well. Some 
that are burnt on a PC at home will not play properly on a 
car CD player. The answer was to burn at a lower speed as 
possible.

I try to burn my data CD's and DVD iso's at a low speed as 
possible.

Kind Regards,

Keith Roberts

Easy:


MAILTO="root"
30 2 * * * echo "this should be mailed to root"
MAILTO="james@harte.x.x"
30 4 * * * echo "this should be mailed to James"
MAILTO="bob"

MAILTO=""

It sets the MAILTO for all entries that follow that MAILTO.  You can 
have multiple MAILTO entries in your crontab, as well as other variables.

If you only have one or two entries that need non-default mail handling, 
you can put them at the end of the crontab.

Dear KB:

You are right-on.  It turns out that the BIOS has a setting "USB 
Emulation", which if turned on, lets a USB keyboard/mouse behave like 
the PS2 version.  With this option turned on, the USB keyboard worked 
throughout the install process.  With this option turned off, the USB 
keyboard was not visible to the first net-install screen, although 
apparently some native USB drivers came into play later.

So here's one "problem" that has evaporated.  On to the next one.

I have had much better luck with DVD data portability if I always 
burn DVDs at 1x (or as close to it as the DVD firmware will allow),
particularly when it comes to burning on one system and reading on
another.

Re: [CentOS] really large file systems with centos

[Devin Reade]

Two thoughts:

1.  Others have already inquired as to your motivation to move away from
ZFS/Solaris.  If it is just the hardware & licensing aspect, you
might want to consider ZFS on FreeBSD.  (I understand that unlike
the Linux ZFS implementation, the FreeBSD one is in-kernel.)

2.  If you really want to move away from move away from ZFS, one 
possibility is to use glusterfs, which is a lockless distributed
filesystem.  Based on the glusterfs architecture, you scale out
horizontally over time; instead of buying a single server with
massive capacity, you buy smaller servers and add more as your
space requirements exceed your current capacity.  You also decide
over how many nodes you want your data to be mirrored.  Think
about it as a RAID0/RAID1/RAID10 solution spread over machines
rather than just disk.  It uses fuse over native filesystems,
so if you decide to back it out you turn off glusterfs and you
still have your data on the native filesystem.

From the client perspective the server cluster looks like a single
logical entity, either over NFS or the native client software.
(The native client is configured with info on all the server nodes,
the NFS client depends on round-robin DNS to connect to *some* node
of the cluster.)



Caveat:  I've only used glusterfs in one small deployment in
a mirrored-between-two-nodes configuration.  Glusterfs doesn't
have as many miles on it as ZFS or the other more common filesystems.
I've not run into any serious hiccoughs, but put in a test cluster
first and try it out.  Commodity hardware is just fine for such
a test cluster.

True. For your kind of usage, I too think (and recommend) you should stick

[CentOS] Chroot issue with username to uid

[Trey Dockendorf]

I'm setting up a chroot environment on a shared web server to allow users to
modify their web roots within a secure chroot, but am having a problem.
 Right now when I log in with test accounts I get this...

Last login: Thu Jul 14 09:04:14 2011 from 
id: cannot find name for group ID 507
id: cannot find name for user ID 506
[I have no name!@webserver ~]$

I've verified that the UID / GIDs are correct in the chroot's /etc/passwd.
 Is there possibly something I may have not put in the chroot that is needed
for id->name mapping?

Here's how I setup the chroot...I'll provide a full write up once I get this
last issue fixed...

cd /home/
mkdir chroot
cd chroot/
groupadd chrootusers
useradd treydock
usermod -a -G chrootusers treydock

mkdir -p ./{dev,etc,lib,lib64,usr,bin,home}
mkdir -p ./usr/{bin,libexec}
mkdir -p usr/libexec/openssh
mknod -m 666 dev/null c 1 3

cp -R /etc/skel home/treydock

/bin/bash /home/chroot/bin/

cp /usr/bin/ssh /home/chroot/usr/bin/
cp /usr/bin/vim /home/chroot/usr/bin/
cp /usr/bin/id /home/chroot/usr/bin/

cp /usr/libexec/openssh/sftp-server /home/chroot/usr/libexec/openssh/

cd /usr/local/sbin/
wget -O l2chroot http://www.cyberciti.biz/files/lighttpd/l2chroot.txt
chmod +x l2chroot
vim l2chroot


for i in `ls /home/chroot/bin/`; do l2chroot /bin/$i; done
for i in `ls /home/chroot/usr/bin/`; do l2chroot /usr/bin/$i; done
l2chroot /usr/libexec/openssh/sftp-server


vim /etc/ssh/sshd_config

What is the reason to avoid ZFS ? IMHO for such systems ZFS is the best.

If it doesn't have to look exactly like a file system you might like 
luwak which is a layer over the riak nosql distributed database to 
handle large files. (http://wiki.basho.com/Luwak.html) The underlying 
storage is distributed across any number of nodes with a scheme that 
lets you add more as needed and keeps redundant copies to handle node 
failures.  A down side of luwak for most purposes is that because it 
chunks the data and re-uses duplicates, you can't remove anything, but 
for archive purposes it might work well.

For something that looks more like a filesystem, but is also distributed 
and redundant: http://www.moosefs.org/.

Remember Solaris ZFS does checksumming for all data, so with weekly/monthly ZFS 
scrubbing it can detect silent data/disk corruption automatically and fix it.

[CentOS] CentOS 6 x86_64 DVD doesn't boot

[Kanwar Ranbir Sandhu]

Hi Everyone,

I downloaded the CentOS 6 x86_64 DVD ISOs and burned the first image to
a rewritable DVD.  When I tried to boot my new home server off it, it
didn't, and then this was printed to the screen:

ETCDisolinux: Found something at drive = EF
No DEFAULT or UI configuration directive found!
boot:

The same disc works fine in my 4 year old HP laptop, and when installing
CentOS 6 as a KVM.

I've found one post from a Fedora 14 user that was having the exact same
problem, but no one replied to him.  Other articles, posts etc. around
the net reference something different for the "EF" part.

Does anyone know what's going on? I've never seen this problem before.

Regards,

Ranbir

After and bit of digging, it appears to be down to a change of a default 
setting in yum with CentOS6

The yum config option multilib_policy is now 'best' in CentOS6 - in 
CentOS5 it is 'all' - which means CentOS6 will only install the x86_64 
version if both a x86_64 and i686 RPM exists in the repo

I guess if I want to revert this back to 'all', I'll need to hack 
anaconda to add 'multilib_policy=all' to the temporary yum config file.

I've also looked into the differences between DVD-R(W) 
disks, and the DVD+R(W) disks. It appears that the DVD+R(W) 
disks are more reliable, as they have better error 
correction methods that their DVD-R(W) counterparts.

So for that reason I only use DVD+R(W) media to burn things 
to.

[CentOS] Is anyone using the Orca screenreader?

[John J. Boyer]

Orca is a daemon written in Python and C which presents the contents of 
a Gnome screen to a blind person in speech or braille. It is on the 
CentOS 5.6 disks. Has anyone on this list used  it? If so, what was your 
experience? I am developing the BrailleBlaster tactile literacy 
application. Since I am both blind and deaf, I will be using a braille 
display. I also need to make sure that the application is usable by 
other blind people.

Thanks,
John

that is one sweet little tablet and I'm seriously struggling with 
whether or not to place an order for one!

Most of solutions concern WINDOWS.
But I will try to find a BIOS-Update.
Perhaps this will solve my proplem.
Or I will update to CentOS 6.

Re: [CentOS] really large file systems with centos

Dev names double, sdaa etc.

My use of XFS has been with great success in 5.x. I have never scaled that
large though.

>C) Is GFS suitable for this, or is it strictly for clustered storage systems?

Unless you plan on mounting the fs by more than one server at once, I
most certainly would not add that layer of complexity, its also slower.

>D) anything important I've neglected?

If I understand, it's not your only backup system, so I don't think it's that
critical, but the rebuild time on each array versus the degraded IO
capacity and its impact on serving content would be something interesting.

Do you plan on making hotspares available? That many discs will likely
have a higher rate of failure...

What kind of discs and controllers do you intend on using?

It might make sense to ask the guys who actually build them?

I think you meant, /etc/ld.so.conf? Anyway, there’s no need to add. But if 
you’re going to add something, it’s a better practice to add a file in 
/etc/ld.so.conf.d instead.

It is. Did you check with “ldconfig -v”?

>  4. Why it is "--with-jpeg-dir=/usr" but not "--with-jpeg-dir=/usr/lib64"?

That worked because you have both i386 and x64 RPMs installed. 

As already pointed out, you could have fixed that by using 
“--with-libdir=lib64”. 

So, if you want to use /usr/lib64, try the following instead:

./configure --with-libdir=lib64 --with-jpeg-dir=/usr/lib64

HTH,

this was a bit unfortunate, for 6.1 we might need to split i386 into 2 
DVD's as well ( there are some more rpms added to the distro at 6.1 stage )

My guess of the culprit would be:
Non-zero Async Control Character Maps are not supported!

Also thing to investigate:
Warning: can't open options file /root/.ppprc: Permission denied

Also try this from Ubuntu Forums:

Re: Can't connect to PPTP VPN
What PPTP settings are you using? I've had this problem for a long time 
as well, although I did manage to find a combination that worked. Give 
it a try:

Tick
- Refuse EAP
- Allow Deflate compression
- Allow BSD compression
- Require MPPE encryption
- Require 128 bit MPPE encryption
- Enable stateful MPPE
- Use peer DNS

Do not tick
- Authenticate peer
- Refuse CHAP
- Refuse MS CHAP
- Require MPPC encryption
