That is my intention, 2 or 3 NICs on the host, to 2 or 3 physical
switches for each dedicated VLAN, then to the iSCSI servers with 2/3
NICs. Would doing so eliminate the impact of using RAID 5 across the
network though? Considering the trade-offs since it is increasingly
expensive to add more storage with RAID 1.

if you can use 2 dedicated ethernet adapters to 2 iSCSI servers  for 
this mirror, its probably a win.

I've spent more time thinking about this and reading over my
research.The crux here seems to be that while RAID does impose
additional write IOPS costs, it may be more than offset by the read
advantage. According to my own notes (which I overlooked in my first
reply), the increased performance from scaling was part of the
original reason I was thinking of using RAID on top of iSCSI.

Searching more on this, the consensus seems to be that RAID 1/10 on
iSCSI is quite okay and may provide read performance increase but RAID
5's iops penalty will probably be a killer.

Re: [CentOS] Affordable KVM over IP switch

Try this 8-port one from LevelOne:

http://global.level1.com/Business-Products/KVM-Switches---Extenders/Rackmount-KVM-Switches/KVM-0831/421.html

It has an expansion slot which accepts a IP module:

http://download.level1.com/level1/manual/ACC-2000v1.0_UM.pdf

I use the base KVM, without the IP module, and it is very stable. It 
connects a USB keyboard and a USB mouse to USB and/or PS2 ports on the 
servers.

It is also cascadable.

I hope this helps.

Read further down, and read the grub man page (from a good system);
'grub-install' is not recommended. I generally go through the manual
process, and suggest you do the same.

Take your time, read things carefully. You're messing with a core bit of
your server.

Not that I've seen in the last 10 years. They're pretty darned
expensive. That's why Dell's "DRAC" and HP's "Sitescope" utilities add
so much cost to the systems.

Hi John,

You would not have to create "dummy" machine records. The
servicePrincipalName attribute on an AD account is multi-valued and
clients can request and get a ticket for ANY principal in that list.
So you only need one account.

And you do not need special permissions if you have an existing keytab
because you can use the keytab to authenticate with AD and add
servicePrincipalName values to the account itself. At least in theory
you can. I don't know if Samba's routine for adding HTTP SPNs is smart
enough to know that it needs to not just add servicePrincipalName
values but that it will also need to rebuild the keytab.

And of course you do not have to use the Samba keytab at all really.
In fact, if you're doing a lot of HTTP virtual hosting (which is
really what we're talking about) you're probably better off just
creating a separate service account, adding SPNs using setspn.exe and
then build a keytab with principals for all of the SPNs with some tool
like ktutil (ktpass.exe will not work though because it only sets one
HTTP principal last I checked - it's a useless program).

In our Plexcel product we have a routine that just queries AD for the
latest KVNO and servicePrincipalName attribute and then generates a
keytab with an entries for each servicePrincipalName value:

  http://www.ioplex.com/api/plexcel_gen_service_keytab.html

This is largely used by the "setup" program of the Plexcel software
for itself but it would be no less useful for just about anyting that
needs a keytab from AD.

With all respect, it is even strange to compare RHEL and OpenSUSE
because OpenSUSE is for SUSE what Fedora is for RHEL (fast lifecycle,
community driven/influenced development platform for the SLES product,
which costs for subscriptions as well).

Yes this will work, dm-multipath and mdraid use different subsystems.

Configure open-iscsi to log into the two targets with two sessions each, setup 
the dm-multipath to arrange the sessions as either a round-robin or fail-over, 
then create a mdraid RAID1 out of the two multipath targets (use their 
multipath identities not their raw identities).

There may be timing issues on system shutdown/startup, so test that fully and 
tweak it until it starts up properly without requiring a resync.

[CentOS] Duplicate Mails

[Ralph Angenendt]

Hi,

due to some idiot not being able to configure his Exchange server
correctly, this list has been swamped by loads of duplicate mails.

There were still several hundreds of mails awaiting delivery to this list.

I have removed all of those from the mail queue - so if you are missing
a mail you have sent, please resubmit it, it probably was lost while I
cleaned the queue as I had no way of telling those apart from the
reinjections.

I am sorry that I had to do that, but I am sure that you'd rather
resubmit than receiving close to 1000 duplicate mails.

The user reinjecting the mails has been identified and shot^Wbanned from
the mailing list, he cannot resubscribe.

Apologies if this caused any inconveniences.

[CentOS] Admin stuff

[m . roth]

Is there something odd going on? The question about the errors in mcelog
just showed up *again*, and it's the original that I answered this
morning. The question about something - was it the md? - original seems as
though it's shown up more than twice today, with the same timestamp, I
think.

Is anyone else seeing this, or is it my host's mailserver?

When I said opensuse, I was referring to suse. Sorry.

The problem I have is that RHEL and SLES are different enough that it's no
small thing for a business to make the change.

I'm guessing RHEL 6 and SUSE 11 are at least equal in quality. (I haven't
tried either of them) Cost of subscription for each seems close.

So it doesn't make sense that a business would switch - unless maybe the
support from Red Hat wasn't great, or if RHEL 6 wasn't great.

I do know that centos 5.5 is great, which in my mind, reflects on Red Hat's
ability to produce an excellent product. And they certainly provide releases
and updates in a timely manner. So Red Hat isn't resting on its laurels.

Are there that many Red Hat customers ready to jump ship? Does their support
suck?

I think both companies should concentrate on providing a good product and
decent service, and not waste time on trying to thwart the competition's
efforts to provide service to customers.

If they all start trying to hinder each other, it seems the beginning of a
war. And the only ones to suffer are IT and the communities. (in other
words, the innocent)

Sorry for my ambiguity, I meant that mdadm would be on the host machine.

e.g. Using just a 2 node, raid 1 situation
Storage 1
-> Disk exported on 192.168.1.10, 192.168.2.10

Storage 2
-> Disk exported on 192.168.1.20, 192.168.2.20

Host
-> mdadm multipath md0 = 192.168.1.10, 192.168.2.10
-> mdadm multipath md1 = 192.168.1.20, 192.168.2.20

Since your exporting the storage as iSCSI, the host machine will see
it as a raw disk, irrespective of how it's setup on the exported
server. So, yes, you can do this.

Rocks 5.4 is not a recompile of CentOS 5, it uses CentOS as its base
distribution, and add configuration, database, tools, MPI, batch job
scheduler etc..., for HPC calculation.

As a yum update may break the configuration, /etc/yum.repos.d/ is empty
by default.

I use myself Rocks, an I populate /etc/yum/repos.d/ by copying what I
have on other CentOS workstations, but avoid to do any update.

With Rocks, you do update by upgrading to the newest version (which
would be Rocks 5.5, based on CentOS 5.6...).

Same page. They're not installing SUSE, they're offering to support
and update RHEL installs.

I know a company that has a few RHEL installs whose RHN subs have
expired and which they're updating through CentOS repos. Not anything
that I'd be willing to do or support but if Oracle's charging to do
something similar to that, they must've tested and tested and tested,
and decided that they have a way of doing it reliably.

matured to where one can reasonable select either on CentOS and our

actually get feature requests accomplished and the authors of the

Novell is essentially offering to help you while you switch existing

Novell's offer may have a lower cost or offer better value then RHEL

Did we read the same page? When you buy Novell (SUSE) support for RedHat
EL, you will still run your original RedHat EL installation but then
update packages rebuilt by Novell. Technically that's the same like adding

Please read the previous posts again carefully and the link that was 
provided:

 http://www.novell.com/products/expandedsupport/faq.html

Novell apparently provides (own rebuilt) updates to RHEL3, RHEL4 and RHEL5 
for the purpose of supporting your setup for up to three years while you 
are migrating those systems.

I guess this is a free service so you can stop paying Red Hat as soon as 
you plan to migrate to SLES. But they expect you to migrate to SLES in the 
next three years...

So this is not related to OpenSUSE.

And maybe the excludes should be written as "exclude=php*5.3.6*".
There is no package called "5.3.6". The way yum presents the RPM
package names can be confusing, but the syntax I just described, with
the wildcards, should work.

Why are you doing this when you can grab the php53 SRPM's from our
favorite upstream vendor and rebuild them for local use? They're
admittedly hung up for CentOS release behind the CentOS 5.6 release,
but these should resolve your dependencies for a more recent PHP.

(See the old thread with me in it for commentary about why it is, or
isn't, in in the CentOS channels yet.)

The only thing that shows there (when it shows, since sometimes it doesn't
seem to) is a hardware error. You *WILL* be replacing hardware, sometime
soon, like yesterday.

"Normal" is not: *ANYTHING* here is Bad News. First, you've got DIMMs
failing.  CPU 53, assuming this system doesn't have 53+ physical CPUs,
means that you have x-core systems, so you need to divide by x, so that if
it's a 12-core system with 6 physical chips, that would make it DIMM 8
associated with that physical CPU.

Bad news: you have *two* DIMMs failing, one associated with the physical
CPU that has core 53, and another associated with the physical CPU that
has cores 32-35.

Talk to your OEM support to help identify which banks need replacing,
and/or find a motherboard diagram.

problem

[CentOS] Cant find out MCE reason (CPU 35 BANK 8)

[Vladimir Budnev]

Hello community.

We are running, Centos 4.8 on SuperMicro SYS-6026T-3RF with 2xIntel Xeon
E5630 and 8xKingston KVR1333D3D4R9S/4G

For some time we have lots of MCE in mcelog and we cant find out the reason.
"Ordinary" mce message looks like:

CPU 51 BANK 8 TSC 8511e3ca77dc
MISC 274d587f6141 ADDR 807044840
STATUS cc005501009f MCGSTATUS 0

decode with mcelog --ascii --cpu p4(cause there is no xeon56xx in list):

HARDWARE ERROR. This is *NOT* a software problem!
Please contact your hardware vendor
CPU 53 BANK 8 TSC 1982d8f72b1f
MISC e1742eac6242 ADDR 7ffd78a80
MCG status:
MCi status:
Error overflow
MCi_MISC register valid
MCi_ADDR register valid
MCA: MEMORY CONTROLLER RD_CHANNELunspecified_ERR
Transaction: Memory read error
STATUS cc000201009f MCGSTATUS 0

The global question is it possible to find out the exact hw which causes
those messages?
First we thought that according to

/* A machine check record */
struct mce {
__u64 status;   /* bank status register */
__u64 misc; /* misc register (always 0 right now) */
__u64 addr; /* address or 0 */
__u64 mcgstatus; /* global MC status register */
__u64 rip;  /* Program counter or 0 for silent error */
__u64 tsc;  /* cpu time stamp counter */
__u64 res1; /* for future extension */
__u64 res2; /* dito. */
__u8 cs;/* code segment */
__u8 bank;  /* machine check bank */
__u8 cpu;   /* cpu that raised the error */
__u8 finished; /* entry is valid */
__u32 pad;
};

cpu is the cpu rised the exception, but we have 2 quadro cpus with HT so
maximum cpu number should be 16 and in logs we see 53 etc.
So no we r not sure about what cpu value is :)Does anyone know what the CPU
number means exactly?

One more interesting thins is the following output:
[root@zuno]# cat /var/log/mcelog |grep CPU|sort|awk '{print $2}'|uniq
32
33
34
35
50
51
52
53

Those numbers are always the same.

Ok.Supposed we have problem in RAM, since i dont really know what those cpu
numbers mean we suppose that cpu+bank can point the problem hw.Is it
possible?
According to our "broken ram theory" we suppose that those numbers
32,33,34,45 and 50,51,52,53 indicate some simetric problem with ram/or slots
or smth else.Is it correct?

Thanks in advance.

RHEL and opensuse are different - defferent kernels, different config files
and slightly different locations for some config files.

It's not like one is a drop in replacement for the other, so it doesn't make
sense to me that a business would buy RHEL support and then switch to
opensuse.

Rocks 5.4 is not a recompile of CentOS 5, it uses CentOS as its base 
distribution, and add configuration, database, tools, MPI, batch job 
scheduler etc..., for HPC calculation.

As a yum update may break the configuration, /etc/yum.repos.d/ is empty 
by default.

I use myself Rocks, an I populate /etc/yum/repos.d/ by copying what I 
have on other CentOS workstations, but avoid to do any update.

With Rocks, you do update by upgrading to the newest version (which 
would be Rocks 5.5, based on CentOS 5.6...).

Well, that *would* explain it. It's not CentOS, it's a rebuild, and
those components haven't been rebuilt.

You'll need to work with the Rocks packagers to provide access to that
tool, or perhaps even strip out a copy of the files from the
centos-release package, particularly
/etc/yum.repos.d/CentOS-Base.repo, mark its repos disabled, and enable
them only has necessary to get specific software packages such as xfig
and transfig.

Re: [CentOS] syslog.conf - how to redirect messages by a program name?

Thank you for your replies.

I've ended up doing the following for my PHP and Drupal logs:

Uncommented error_log = /var/log/php/php_errors.log in /etc/php.ini
# mkdir /var/log/php
# chown -R apache.apache /var/log/php

Appended following line to /etc/syslog.conf
local6.*   /var/log/php/drupal.log

In Drupal modules screen enabled Syslog module
and diabled Database Logging module

In Drupal settings screen changed Syslog to LOCAL6

(And later I'll add rotation scripts under /etc/logrotate.d )

Right. The php53 package is in the upstream vendor's updates, all of
which are held up for CentOS release behind the 5.6 release. I'd like
to see it get somewhere into the CentOS 5.5 releases, even if it's one
of a select few components in the "updates" that are published in the
5.5 release.

It's hard to consider CentOS "equivalent to the upstream vendor's OS"
if the updates are so far behind that commonly available packages are
incompatible with it.

As the faq states
(http://www.novell.com/products/expandedsupport/faq.html) Novell simply
rebuilds the RHEL source rpms and sells them to RedHat customers.

So, it's like CentOS, but only with updates, no full distribution, no
installer, but you can pay for it :)

As far as I understand (I don't have first-hand knowledge of this aspect
