Re: [CentOS] Re: 6TB SCSI RAID vs. Centos

[Tim Nelson]

I'll second that... we recently put a system online with over 3TB of storage. 
The only way to create a storage medium that large was to use a gpt disk label 
and use parted to do the partitioning. mkfs had no problems formatting the 
partition and it's been working properly for quite some time now.

Did you try creating GPT partitions with parted? Fdisk won't do it.

In this case, it was about 7 minutes later. I know you are one of the
people on this list who use IPCop at work. One of the 3 updates
requires a reboot for the updated kernel. I told my wife and daughter
they were going to lose connectivity for several minutes. At work, you
do the reboot at  3 A.M.  or you have users who are furious, or you
send them a message the network is going down temporarily?

The phone company replaced our ADSL Modem and with the change to
opendns.com our Internet service is working *much* better. :-)

What Craig implies is that your system won't be available for quite a 
long time (relatively), while the relabel takes place.  The boot time 
with an autorelabel is very long, and you won't have access to the 
server until the relabel is completed.  So choose your time for the 
reboot with that knowledge.

That is with 2 dualcore XEON's at 2.2 Gh and 4 gigs and a SATA raid 5 (3ware)..

I have a spare, but not 3.

The average looks average.. with stats only collecting once every
10 minutes it's hard to say. I collect my stats using sar and pipe
them into cacti every minute.

If you get say into the 25-30% range I'd be concerned.

What kind of mail system are you running ? Is it simply a SMTP relay
or is mail being stored on the system and users accessing it? If
users are accessing it what type of mail storage(mbox, maildir, cyrus
etc).

You can try rescanning the bus:

But it sounds like despite what the qlogic app says the devices

What have you done to try to get it working?

http://www.cyberciti.biz/tips/fdisk-unable-to-create-partition-greater-2tb.html

Last I recall drives larger than 2TB weren't "officially" supported by
Red hat so it may not be perfect.

The last infortrend systems I used supported exporting logical drives
of smaller sizes which worked for me.

Last I heard you couldn't boot off of drives larger than 2TB with a
normal bios(with Intel's EFI I think you can?).

installed the latest (v8.02.14) drivers from Qlogic for the HBA


The issue I have is I am missing 2 of the 4 SDLT drives provided by the 
M1800 Library.  The DX30 provides 6 drives, which are listed in dmesg 
and assigned /dev/st0->5. I would expect the SDLT's to be st6->10 but I 
only see up to st7 and dmesg only lists 2


Using the QLoigic SAN Surfer software all the LUN's/devices are visible 
to the host.


FYI, I also have an old Sun220R connected to this same switch with a 
qlogic card; Solaris 9 has no trouble seeing all LUNs and devices.


I've "googled" for a fair while and have not see anything that helps. My 
FC knowledge on CentOS is limited so any help with troubleshooting this 
would be greatly appreciated.


TIA

[CentOS] 6TB SCSI RAID vs. Centos

[Milt Mallory]

I have an Infortrend RAID box I'd like to see as one big 6TB partition,
but I only can get 2.2TB partitions to work. I was trying to do this
with an Adaptec controller but apparently they are only (any of them) 48
bits wide. Does anybody have a working system for SCSI/Centos over
2.2TB?

Or you may be forwarding to an unpatched DNS server, or you may be behind a NAT
devices that remaps the source ports on outgoing requests.

[CentOS] Re: IPCop updates, Evolution Calendar rarely crashes now

[Scott Silva]

on 7-24-2008 2:41 PM Lanny Marcus spake the following:

I know a lot of you are using IPCop where you work. They have three
(3) updates posted, during the past two (2) days. The last one, I'm

Sometimes their updates take a while to hit the mirrors. I don't think they 
delay the announcements until the mirrors are synced.


The problem I was having, after the huge update to 5.2, with the
Evolution Calendar (which I do not use) crashing, when I exited from
Evolution, has almost
completely disappeared. One or more of the updates since the huge
update eliminated most of that problem. It seems to only happen now
when I am going
to log out of my Desktop or shut it down and only rarely.

They are now using OpenVPN instead, and are very happy with it.
I know openvpn is a better solution i'm using it to connect the branch offices

We use pptp because the easy configuration on the user's computer, there is no

You might want to take a look at joining up with rpmrepo for
distribution of packages. Folks are (sometimes with good reason)
reluctant to use packages from individuals. Rpmforge/rpmrepo are
respected repositories, and you'll be able to take advantage of plenty
of developer expertise.

[CentOS] You didn't give me some packages, so now I'm giving you some! R, TexLive, LyX, Gnumeric, etc.

[Paul Johnson]

I want up-to-dateish versions of TexLive, R, gnumeric, emacs, but on a
more-or-less stable base of Centos-5.2.  I asked for packages in this,
but got no answers. So now I've built them and will let you try them
if you want. I used the source packages from Fedora 8 and 9.

I wanted TexLive because many of us have jumped ship to Ubuntu Linux
8.04 and it does offer TexLive, and the compatability across systems
became an issue.  With Centos5.2 shipping the years-out-of-date tetex,
we were seeing things compile differently across systems. Making
TexLive compile and install required a re-build with a newer version
of poppler, but not with the absolutely newest version of poppler.
Replacing poppler required a rebuild of evince.  After emerging from
dependency hell, it all seems OK.  I uploaded the src.rpm files for
the packages that I actually had to re-configure, even in the
slightest.  Otherwise, everything is in Fedora 8 or Fedora 9.

We use LyX to edit LaTeX, so I had to have a newer version, along with
pybliographic (which required recode).  We also use Emacs and auctex
to edit LaTeX, so those had to be built as well.

All of these packages were built on a stock Centos 5.2 system, with
all components as usual EXCEPT for the ones I provide below or the
packages that can be downloaded from EPEL.  As far as I can tell,
everything works as well as it does on Fedora, no better.

When I had a request recently to implement pptp on CentOS 5.x,
and found that it was not supported in the standard kernels and
repos, I took that as a great opportunity to get the customer
away from PPTP (the work of Kindergarten Cryptographers according
to at least one well-know security site), to something better.

They are now using OpenVPN instead, and are very happy with it.

I doubt it will make a BIG difference, but you might be looking for 
trouble running a highly active server of any kind on a single spindle.




I have a Communigate mail server that was running on a single WD 200 
Gigs IDE (7200 RPM).  Communigate uses separate mbox files for storage, 
very easy for backup / restore.


I was monitoring it with SAR and there was very high level of IOWait, 
meaning the drive was having a hard time.


Context:

35 Users Running Outlook with Communigate MAPI Plugin
80 Gigs dataset (Total)
Public folder with about 50 Gigs of stuff

We replaced the server with a Tyan Transport TA-26.  We put an Adaptec 
3405 (4 ports Unified SATA/SAS adapter) and 4 Seagate 15K SAS 73 Gigs 
drives (RAID 10).  No more iowaits even if now there is 50 users.


I don't know about your context but running on a single drive is 
dangerous for data loss anyway.


Hope this helped!

if you just turned selinux on after running the computer with it
disabled, you really need to relabel the entire filesystem, which does
take some time. The reason is that files have been installed/created
without the appropriate contexts and relabeling fixes that.

Suggest that you make sure you are fully updated, then
'touch /.autorelabel' then reboot (reboot at a time you choose because
it may take a long time to relabel every file on your system -
especially if you have a lot of files).

[CentOS] pptp server configuration

Hello all,

i'm using the poptop server with centos 5.2 to give the vpn service at the 
company i work for. Some people are using the same account to use the service.

've been searching in google and the poptop site but i have not found any 
information about blocking multiple connections using the same account. The 
goal is to restrict only one connection per account.

Any suggestions or pointers to documentation will be really apreciated.

[CentOS] selinux & httpd & portmap

[Toby Bluhm]

Having problems starting httpd & portmapper

#service httpd start
/usr/sbin/httpd: error while loading shared libraries: libm.so.6: cannot 
open shared object file: No such file or directory


and I traced it to selinux, which I had just turned on for the first time:

# sestatus
SELinux status: enabled
SELinuxfs mount:/selinux
Current mode:   enforcing
Mode from config file:  enforcing
Policy version: 21
Policy from config file:targeted

I can

#setsebool -P httpd_disable_trans on

and httpd starts - but there's zero enforcing now as I understand it.

Further digging & I get to:

# cat /var/log/audit/audit.log | audit2allow -m local

module local 1.0;

require {
type portmap_t;
type httpd_t;
type file_t;
class lnk_file read;
class file { getattr read execute };
}

#= httpd_t ==
allow httpd_t file_t:file { read getattr execute };
allow httpd_t file_t:lnk_file read;

#= portmap_t ==
allow portmap_t file_t:file { read getattr execute };
allow portmap_t file_t:lnk_file read;


Other stuff like postfix, postgrey, amavisd are working fine since 
turning selinux on.


Before I make a mess of things with trying to make a new policy, 
shouldn't two basic services like portmap & httpd already be allowed to 
run out of the box by selinux?


If not, am I going down the right path to get it working?

Thanks

I doubt it will make a BIG difference, but you might be looking for trouble
running a highly active server of any kind on a single spindle.


Some decisions made in past are hard to undo down the road.  Would
like to move to CentOS 64 5.x with RAID but moving everything too a

You could easily move to a software raid1 with very little downtime and a few 
reboots. It might also help slightly with read latencies, but wouldn't help 
with writes.

Isn't there something like disk i/o ladder in the linux kernel that

[CentOS] Possible bug in ifup-eth script of Centos 5.2 (combination of bond and bridge)

[Marco Fretz]

Dear CentOS,

I think i found a "bug" in the /etc/sysconfig/network-scripts/ifup-eth script 
of CentOS 5.2. i can post the my changed ifup-eth script if you want. 
Am I the first one with this problem?

Situation: 
- eth2 and eth3 should be in bond1 interface
- bond1 should be an interface of bridge named "iscsi"

the problem is that the brctl addif command in ifup-eth gets executed before 
the slave interfaces of a bonding are enslaved.

brctl addif fails if you are trying to add a bonding interface to a bridge and 
the bonding interface have no slaves.

my solution was to switch the order in the ifup-eth script:
- to the bonding (slave interfaces) stuff before the bridge stuff

and its working... the bonding interface gets his slaves and can be added to 
the bridge without any errors.


best regards
 Marco

Consider  using djbdns instead of BIND. It sounds like an excellent alternative

We have been using djbdns for years on a variety of Linux platforms and

But I also know Vixie etal quite well and I stay with BIND.

As for not having it supported on CentOS, I really don't care about that as
the majority of the server software we use is built under the OpenPKG.org
portable packaging system, independent of the underlying OS vendor's
packaging system.

Thanks for the responses. Grepping for VMware in /proc/scsi/scsi or

[CentOS] OT: backup media options

[Monty Shinn]

Greetings.

Sorry for the OT, but I'm looking for some advice regarding archiving.

I've always been a tape archive believer, but with SATA drives becoming 
more reliable and much larger, I'm wondering if it is time to change my 
opinion.


What are the benefits/pitfalls to begin archiving to "enterprise" level 
SATA drives?  Is it possible to use Amanda or Bacula to archive to a 
drive, and maintain a archive regimen?


Archive to the drive, when the drive is full put it in an anti-static 
bag, and place it in storage.  Possibly archive to a mirrored pair if 
one is really concerned.


We are considering using LTO4 as an archive medium.

With the tape densities these days, it appears the tapes are rather 
fragile, and that head gap seems awful small.


Any thoughts are greatly appreciated.

Again, I'm sorry for the OT, but I figured I'd get knowledgeable 
responses from this list instead of sales pitches...


Thanks in advance for your time.

This script does the trick for me on ESX 3 by looking at the (virtual) hardware 
description. But it probably is not foolproof.

if ( `/sbin/lspci | grep -qi vmware` ) || \
   ( `grep -qi vmware /proc/scsi/scsi` ); then
echo "This is a Virtual Machine."

Alternatively, grep the output from dmidecode for VMware:

dmidecode | grep VMware

You'll get output from VMware Server, I've not tested with other VMware 
products.

This script does the trick for me on ESX 3 by looking at the (virtual) hardware 
description. But it probably is not foolproof.

if ( `/sbin/lspci | grep -qi vmware` ) || \
   ( `grep -qi vmware /proc/scsi/scsi` ); then
echo "This is a Virtual Machine."

This paper show some very interesting tricks:

http://handlers.sans.org/tliston/ThwartingVM*Detection*_Liston_Skoudis.pdf

One simple (but not really foolproof, and only for VMWare) is testing
the MAC address, and look at the OUI bytes; these are assigned to VMWare:

 00-05-69
 00-0C-29
 00-1C-14
 00-50-56

[CentOS] How to detect whether running on VMware?

[Tony Mountifield]

Does anyone know how a program, script or shell user can best determine
whether the machine is running on bare metal or is a VMware guest?

Cheers

maybe it's memory problem, becuase of the ( out of memory), how much ram you
got there?
was it working before rebooting? if yes, did you installed any new services
before the reboot?

The firewall is the same, IPtables. The front end interface can be different. 
I like FWbuilder because it give the most flexible of any front ends I have 
seen.

Re: [CentOS] Help recovering from an LVM issue

Hi People

I just updated a CentOS 5.2 Server that is a Guest inside VMware ESX 
3.50 Server using  "yum update".  As far as I can tell the only three 
packages were updated


Jul 24 16:37:49 Updated: php-common - 5.1.6-20.el5_2.1.i386
Jul 24 16:37:50 Updated: php-cli - 5.1.6-20.el5_2.1.i386
Jul 24 16:37:50 Updated: php - 5.1.6-20.el5_2.1.i386

But when I rebooted the Server one of my Volume Groups VolGroup01 
would not mount.  By removing all references to VolGroup1 in 
/etc/fstab I was able to get a system that boots.  Unfortunately I am 
not that familiar with LVM but using the following commands it looks 
like all the information about my logical volumes on VolGroup01 is 
gone is this correct?  Is there likely to be any chance of recovering 
from this ?

Thank you for any advice you may have relating to this.

Please Ignore this message.  The /etc/fstab on the system was 
incorrectly modified by a vmware related script and I was too tired / 
stupid to spot what happened and have spent the last while chasing a 
problem that doesn't actually exist.


Apologies for the noise.
