Nagios 3 RPMs
Is anyone working on Nagios 3.x RPMs? If not, perhaps I'll whip some up and
submit them to some appropriate repository.

Setting up Linux File Servers in a University Environment
Hello Everyone
I work for a University Department that has a high number of Linux
Desktop Users. Currently we provide a users home directory via NFS from
a file server. Generally it works well for us, but I have been asked to
look at our options for expanding the storage we have available.
So I thought one of the first things I had better do is consider are
there alternatives to the way we

dm-multipath use
Are folks in the Centos community succesfully using device-mapper-multipath?
I am looking to deploy it for error handling on our iSCSI setup but there
seems to be little traffic about this package on the Centos forums, as far
as I can tell, and there seems to be a number of small issues based on my
reading the dm-multipath developer lists and related resources.

centos IDM + sogo
Hello,
We are testing the Centos LDAP Directory Server but are running into issues
with applications (SOGo) authenticating against the LDAP system. The crux
of my question is, can I just treat the Centos Directory Server as a generic
OpenLDAP configuration on the client side?
In more detail when I try to add account via ldapadd:

OT: SysAdmin Stories
Hello,
I'm compiling a collection of stories from the systems administrator
trenches. They can be short or long, funny or about a particularly
challenging problem or period, or even something that appeared very
technically challenging and ended up being something very simple. Stories
which are more political would be ok so long as they do not have an agenda
or can be interpreted as a

device driver useage
Under Centos 5.X, how can I determine with 100% certainty what driver is
associated with a given device other than referencing dmesg? For example,
what tool can I use to tell for sure what driver is attached to my eth0
device?
I have searched the web, but could not find anything that answered my
question.

commercial support page
So we had that nice long thread about the commercial support page a week
ago. There were a few recommendations on changes to the page. What next?
It is not clear to me if any recommendations were accepted or are being
debated internally or if this fizzled out somehow. Is there any process to
this kind of thing other than a few developers agreeing it a good thing and
then just doing it?

Have folks been using Cmake on Centos5 without issues? I have installed
an RPM for it, but I've been running into some apparent configuration
issues.

NFS exporting a GFS mount point
Hello,
I have a storage offering some 11 TB of space. I'd happily use ext3
and NFS export to 4 client machines, but 8 TB seems to be the tested
maximum. I'd really like one mount point for the whole 11 TB. Since
GFS offers lock_nolock option for local mounting, I'm assuming it's not
so out of line to NFS export this GFS mount point.
Thoughts and inputs appreciated.

German Centos/Linux Group in Cologne/Bonn/Aachen
It seems there are a number of Centos users in the Cologne/Bonn/Aachen area
of Germany. If there is not one already (and please let me know if there
is!) I'd like to start a Linux User Group (including Centos) for this area.
I'm way down in Blankenheim, though. Would someone like to volunteer a
location? I envision alternating meetings between the three cities if

GFS performance under heavy traffic
Hi David,
Also consider using the mount option to specify backup server via 'backupvolfile-server=server2:server3' (you can define more but I don't thing replica volumes greater that 3 are usefull (maybe in some special cases).
In such way, when the primary is lost, your client can reach a backup one without disruption.
P.S.: Client may 'hang' - if the primary server got

Server packet loss and becomes unresponsive
?
Does "ifconfig" or "dmesg" show any errors??? If the answer to those is
no, I'd start running sar to see if there is abnormal behavior which could
indicate a hardware problem.?? Of course, another possibility is a
DDOS.? Do you have any kind security monitoring or protection in place?

Dovecot and SATA Backend
Hi all,
I plan to run a dovecot IMAPS and POPS service on our network. We
handle about 3 000 mailboxes. I thought first buying a topnotch server
(8 cores and 16 Go RAM) with equalogic iSCSI SAN SAS 15K for storage
backend.
On second though (and after a comprhensive read of dovecot features),
I saw in http://wiki.dovecot.org/MailLocation that index files can be

iSCSI best practices
Hey folks,
I had some general questions and when reading through the list archives I
came across an iSCSI discussion back in February where a couple of
individuals were going back and forth about drafting up a "best practices"
doc and putting it into a wiki. Did that ever happen? And if so, where
is it?
Now my questions :
We are not using iSCIS yet at work but I see a few places

zfs list extentions related to pNFS
Hi,
I am soliciting input from the ZFS engineers and/or ZFS users on an
extension to "zfs list". Thanks in advance for your feedback.
Quick Background:
The pNFS project (http://opensolaris.org/os/project/nfsv41/) is adding
a new DMU object set type which is used on the pNFS data server to
store pNFS stripe DMU objects. A pNFS dataset gets created with the

Xen, GFS, GNBD and DRBD?
Hi all,
We're looking at deploying a small Xen cluster to run some of our
smaller applications. I'm curious to get the lists opinions and advice
on what's needed.
The plan at the moment is to have two or three servers running as the
Xen dom0 hosts and two servers running as storage servers. As we're
trying to do this on a small scale, there is no means to hook the
