[CentOS] Sword Project for centos 5

2007-10-15 Thread fred smith
Hi!

Anyone know of RPMS for the Sword Project (and Bibletime and/or
GnomeSword) for Centos5/RHEL5?

Latest RPMS I've found have a ton of dependencies, some of which are older
than packages I've already got.

Thanks!

CentOS-5 kernels are all smp-enabled but they work on uni-processor
systems just fine.
If you, for some reeason, must use a UP-kernel, you'd have to rebuild
it from the source.

Yes ... there is only an SMP kernel shipped.  It works with 1 or more
processors.  It does not have SMP in the kernel name, it does show SMP
in uname -a.

I forgot to mention 


if you are interested you can safely run vmware on an openvz kernel. 

Openvz is more like solaris zones/containers.

Guys, 

you can't do this. 


If you try and run vmware on a Xen kernel you will panic/crash the box as soon 
as you try to startup a vmware vm. 


Both Xen and vmware run in ring 0.

Not without patching a lot of stuff. When someone asked this a while 
back.. there was a lot of conflicting code and when they got past that 
it just crashed. To put it another way, both are ball games that look 
alike: Cricket, American Baseball.. beyond throwing a ball, hitting,

Did you try their management software to see if you could view the
health and status of the array?

It may be marked offline internally from the previous failure and
needs manual intervention to bring it back online.

Try installing and configuring the status monitor software from:

The way I understand it:
Is that the external array or DAS can be serve as a storage device for two
servers.
So I should have to migrate it over to the B channel.

Did you go from a SmartArray to a standard u-320 SCSI controller?
The reason I asked is:
Could my problem be because the the DAS was originally partition and

so give "tune2fs -l /dev/sda" a try. Maybe you'll find a nice ext3 fs,

maybe

no. It's a non-destructive operation so go ahead.


That yielded :'(
tune2fs 1.39 (29-May-2006)

Couldn't find valid filesystem superblock.

And know they didn't backup their data, under the advice of their developer.
Advice to everyone if you care about your data BACK IT UP!!! even a raid 5
with hot spares can fail.
I feel bad for them. Thier developer screwed them and then left them.

If any has any other advice please share.

Any decent rescue disk should have testdisk 
(http://www.cgsecurity.org/wiki/TestDisk)

Run it against the array and see what it can find.

The smartarray sees it as a raid0 with one drive because that is how its bios

drive and it would show up as a raid0 stripe with one drive.

Well,

  from this I'm thinking you didn't need another SmartArray, but it looks
like the A channel from your DAS is the problem... Try look on the DAS manual
for the configuration options (how the RAID drive are made) and try to search
a way to migrate the RAID from channel A to B. Look for a way to acquire as much
info on the DAS configuration you can before trying it. I already had changed 
RAID disks from one controler to another (SmartArrays by the way), and the RAID 
disks are found without problem. But, if it didn't work and the DAS "rebuild" 
it's
RAID the data on the disks are gone :(

  another way is trying to contact the DAS maker and their tech assistant.


Antonio.

you don't need regex:

sed \

-e 's/,/ \& $/' \
-e 's/\./,/g'  \
-e 's/e/ \\cdot 10^{/' -e s'/$/}$/' \

now, the exercice is to read the input file directly with LaTeX using

Is there a way I can get the data off the array with my Centos server?

Try "mount -oro /dev/sda /mnt/tmp" (or whatever) or just see if

No..
He said he had a sata to scsi raid array in a box that connects multiple sata 
drives to a single scsi port. Looks like a single drive to the connected system.

you don't need regex:

sed \

It might be extremely useful to combine this with the Centos

Not without patching a lot of stuff. When someone asked this a while
back.. there was a lot of conflicting code and when they got past that
it just crashed. To put it another way, both are ball games that look

The array that I'm tyring to recover is a SCSI-toSATA 2U external Raid
device.
It connects to any u320 controller and is suppose to show up to Linux as 1
SCSI drive.
Quote from the manual:
"These host interfaces are host O/S independent and will operate on any
system that has a working SCSI or Fiber interface
The DAS is made up of several components including a RAID controller,
backplane board with intelligent environmental monitoring, chassis, power
supplies, fans, front control
panel with LCD display and hard drive bays."

>Are all drives from the old array
> connected?  Without having the drives attached to the original
All the drive are in the external array, and it says the Array is
functioning properly.

The Smart Array card that it was originally connected to doesn't recongize
it.
The SmartArray is in a working server and is currently running an internal
Raid 5.

My guess is there was some hardware failure on the external side of the
controller or the external array.
My reasoning for this, is if I connect the A Channel of the external array
to my Centos server
my SCSI card doesn't recognize it. But if I connect it to the B channel side
it does

I would love to be able to connect the external array to another SmartArray
controller and see if it recogizes it, but I don't have one.

That yielded :'(

tune2fs: Bad magic number in super-block while trying to open /dev/sda
Couldn't find valid filesystem superblock.

And know they didn't backup their data, under the advice of their developer.
Advice to everyone if you care about your data BACK IT UP!!! even a raid 5
with hot spares can fail.
I feel bad for them. Thier developer screwed them and then left them.

So thats why I connected it to a SCSI non-raid controller which does.

The external array has it's own built in raid controller.

I not sure why the SmartArray sees it as that because the external array is

What do you mean by connected it?  Are all drives from the old array 
connected?  Without having the drives attached to the original 
controller you may not be able to get much from it, Linux would still 
see the individual SCSI drives but that doesn't help if you want the

You may want to take the old RAID card out of the other server and 
install it, that is the only way you're going to get anything from it.

Since he only mentioned one device on his centos, there are centainly 
plausible ways this could work. The original cciss array could have been a 
single drive, could have been a raid1, could have been a misunderstood hwraid 
just tunneled through the host adapter as a single driver, etc.

We'll just never know until he either tries or gives us more info.

If you plan to run CentOS 5, why not install it directly? If you want a
smaller installation medium, you can download the
os//images/boot.iso ISO image and do a minimal netinstall. You
could also use just the first CentOS 5 CD and do a minimal install
(disable all software groups).

This is great!  Been looking for this for a while.  Just created a

I would like to point out that this MIGHT be how we build the livecd for
CentOS-5.1 (I would even say PROBABLY will be) ... however it was not
how the livecd for CentOS-5.0 was produced.

It might help you in your particular efforts though.



Does anyone have any suggestions for persisting configuration changes  
to floppy or other media like USB stick?  I don't want to create a new  
image every time a firewall rule changes, and I need changes to  
persist after a reboot.


I'm having a hard time finding information on this subject.  I was  
hoping for something a little more elegant than mounting a floppy via  
fstab and using symlinks to relocate configuration files like  
"/etc/sysconfig/iptables".  I'd like to use a single image for several  
machines.  Each hostname, firewall rules, ip addresses, etc would be  
saved on a floppy that's specific to that machine.

The partition table could be hosed. You might want to consider sending the 
unit out for recovery if it is critical data and you have no backups.

You might be able to scan it with testdisk and see if it finds anything.

Or try the tools from the array manufacturer if they have any.

In centos5, there is no longer a separate smp kernel. It's supported
directly within the main distribution kernel now. If you're using an
smp system, you'll see SMP listed in uname -a.

This was a change in the main kernel tree as well, though I don't
recall the exact version this started. I think around 2.6.16 or so.

what do you think ?

I have had systems so overloaded that I couldn't log in on an ssh session, but 
when the load cleared, there weren't any ECC errors. I still think you have a 
hardware problem, and just because it takes a high load now doesn't mean that 
it is OK. A faulty timing capacitor on the motherboard can cause all sorts of 
corruption in memory, and it will probably deteriorate over time. You need to 
methodically test the memory by running memory tests, and then moving ram and 
testing again. Or replace the hardware if it is mission critical.

[CentOS] is there an smp kernel?

2007-10-15 Thread Chuck Campbell

I have a dual xeon, dual core box running the xen x86_64 kernel.
I've decided against running any guest OS'es most of the time, so I'd like
to install an smp kernel, that would hopefully allow me to install and
use the nvidia drivers for my quadro FX1500 graphics card.

I did a yum list kernel* but I don't see any smp kernels.

Do I need to do a full reinstall w/o virtualization, or does the plain
kernel.x86_64 0:2.6.28-8.1.14.el5 support smp?

I spent an hour or so googling and didn't find any clear answer, but I may
not have looked in the right place.

This is an odd dep chain. It would seem that exim requires mysql for
some odd reason. mdadm doesn't, but does require that the system have
an smtp-daemon, which is a dep satisfied by exim, postfix, or
sendmail.

mostly, install sendmail or postfix, and you can then remove exim and
mysql without fear.

[CentOS] mdadm exim mysql

I installed a CentOS-5 core OS (using --nobase in my kickstart).

For some reason, it included mysql-5.0.22.

When I do "yum remove mysql", it says it will also remove 
exim and mdadm for dependencies.


I don't care that exim will be removed, but I need mdadm as 
I'm doing software RAID.


But why are these even related? When I do:
rpm -q --requires mysql
neither exim or mdadm is listed as being a requirement.

Craig,

php-pecl(memcache) should be provided by
php-pecl-memcache-2.1.2-1.el5.centos that is in the extras repository.

It seems that you are trying to update that file (php-pecl-memcache)
with one that does not provide "php-pecl(memcache)".

Specifically, looking at the one in RPMForge repo, it (for some reason)
does not provide "php-pecl(memcache)" ... so it would seem to me that
you are trying to upgrade your php-pecl-memcache with one from RPMForge
... if so, try using yum-priorities and giving the [extras] section in
/etc/yum.repos.d/CentOS-Base.repo a priority that is higher (a lower
priority number) than RPMForge.

You may add those devices to fstab, much like partitions:

/dev/sda2 /mnt/pendrive2 vfat noauto,users,rw,umask= 0 0

the key is that "users" param, to allow normal users mount and umount 
filesystem; I very often use static mount points and edit fstab instead 
of using HAL for this, but HAL itself respects fstab configuration too


all parameters are listed in mount docs, but since those are removable

Ann,

Depends on what you are going to use your Linux box for, home box it's
not that critical. On a large scale environment that network card
would be more interesting since it can scale I/O interrupts in a way
that require less work for the CPU in high traffic environments
compared to a conventional network card etc. It is indeed a huge
difference between desktop and server hardware as you will also notice
on the price tag.. ;)

However, if you look at that script and follow it through into mkimages

I would like to point out that this MIGHT be how we build the livecd for

how the livecd for CentOS-5.0 was produced.

It might help you in your particular efforts though.

Jerry,

Just an idea, what about using LVM as a partition manager and ext3,
reiserfs, jfs or xfs where you can extend partitions on the fly (no
unmounting so no downtime for DB's etc). Works fine for me with 2 TB
partitions (not needed to go beyond 2TB yet..) on SAN storage.

What do you mean by "transferring data from other storage to this one"
?These are main memory (RAM) ECC errors and have nothing to do with
disk storage, networking, or anything else.

and, 'writing data to it', its not clear what the 'it' is referring to.

Storage - anything that can store data. ECC is a generic term and 
covers all kinds of checksumming algorithms. I was talking pretty 
generic - don't care if ram, caches, nand-flash, ficon or anything else.
I was trying to get across that its hard to pinpoint where your bits 
flipped - in the storage device, on the transmission there or back.   
if they flipped in a disk storage device, you would have gotten a disk 
storage related error, typically reported as a "CRC" error even tho 
modern disks haven't actually used CRC since the 80s. 
systems don't tend to transmit and store the ECC across different 
device domains.
if they had been read off the disk in a 'flipped' state, then they 
would have been written to RAM just as they were read, and the RAM 
would have created its own ECC on the 'wrong' data quite happily.


anyways, the error in question...

> : EXCEPTION: ECC Error Interrupt (Two or more Bit Error)
> 0C18:00020001 0C68: Lcause:74630001 Lerr:1C855F82

is almost certainly a RAM ECC error, so I was asking the original 
poster just what he meant by 'transferring data from other storage to 
this one' as it sounded like he was thinking in terms of overall 
server operation rather than the specific component level.



if he was talking about copying files from one disk to another, then 
that data has to be read from the source disk and written into ram, 
then read back from ram and written to the other device.  in fact, its 
possibly been copied a few times in ram in the process too, so talking 
about transfering between storage really isn't very helpful here.

Fix your /etc/fstab so it does not check your FAT32 partitions on bootup.

[CentOS] Re: Using XEN VMs with non-US keyboards?

2007-10-15 Thread Felix Schwarz




I'm seeing the same problems on Fedora 6+7. I don't think there is a real 
solution (btw: using a German keyboard layout, shift+6 gives me "/" in the 
graphical vnc console). I use SSH for virtual console management as much as 
possible.

Could you also please learn on how to not abuse a mail program -
meaning: Teach your program to *not* break all quotations from previous
mails into a single line (2008 characters in this mail)? It makes
reading your replies quite a PITA - for all of us.



IOW: Please do not use Hotmail.

Use http://rpm.pbone.net/ to get src.rpm, and rebuild it for your version of
CentOS.

[CentOS] zebra-0.95 rpm

2007-10-15 Thread Indunil Jayasooriya
Hi,

I want to run zebra on CentOS 4.5 box acting as a firewall and router. I 'd
rather like to user RPM. So I am lokking for a proper RPM.

I now googled. But I could not find any for EL4 for CentOS 4.

YOUR IDEAS?

I would like to do so but the things I want to add are very specific for
our companies operations department and have less or no value at all for
the public domain.

Gr.,
John

while not really an answer to your question, I would like to ask you to
file an 
issue report about things that you consider should be on the livecd but
are not 
( http://bugs.centos.org ) - so that we can actually do something about
it for 
the next livecd release.
