Your Customers are unhappy because they don't know what you do.
The Release and QA Process seems recently to have become a mirracle.
There is nothing discussed where your Problems are in getting things
done.
So if nobody knows where you are stuck. (Who are the persons anyway
hidden in the secret labs?!) Nobody can step up and help out.
Where is this discussion maintained anyway? The Currents process is
untransparent. And for a COMMUNITY Enterperise Operating System
this fact is not acceptable.
We know that the big boys at RH changed the whole system, but the
community accepted that you need time for 6.0 to adept to these changes.
Since then we all thought the issues would have been solved. So what
now? What exactly is holding of the release of 6.1 and where can we as a
community step in and help?
If you aren't happy, well then we would recommend something else that
does make you happy.
Or give us the possibility to help becoming happy again. But doing it
like Dumbledore in secret regions of the Centos-Hogwards Terrertory is
an bad option as it seems.
Happy is important ... don't go through life unhappy because of an OS.
You seem very unhappy at the moment ;)
We just want you to be happy Les.

Re: [CentOS] LVM lvresize/lvextend requires some space in /etc to grow a logical volume?
Am Montag, den 19.09.2011, 19:15 -0400 schrieb Johnny Tan:
Anyway, here's the real issue with LVM, at least in CentOS-6:
You would deal with the same issues in older lvm versions.
[root@jttest ~]# df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/vg_main-lv_root
1548144 1548144 0 100% /
Do i read that correctly and 1548144 1K Blocks are about 1,5G of Root
File System? Please tell me you have a seperated /var for log files.
If not, for production use, install a tool which gives you a warning
when reaching the 5% Level.
[root@jttest ~]# lvextend -L 2G /dev/vg_main/lv_root
/etc/lvm/archive/.lvm_jttest.pp.local_5523_51321310: write error
failed: No space left on device
Volume group vg_main metadata archive failed.
/etc/lvm/cache/.cache.tmp: write error failed: No space left on device
So I can't extend a logical volume if there's no space in /etc?
lvm tries to be helpfull if you ran into a power failure and can then
recover due his tmp files in /etc.
Granted, I only need to delete like 2k worth of files in the same
logical volume as /etc to make the above work, but I don't recall
lvresize or lvextend requiring space in /etc to do a resize. Has this
always been the case? I don't have any 5.x servers handy to test this
with. Can anyone verify?
You will have the same problem, i think this procedure is the same in
all lvm2 versions, which seems a long time now.
If this is new, this seems less-than-ideal. /etc itself rarely fills
up, so, in theory, I could make it its own LV, but that's even less
ideal. For now, I'll stick to deleting just enough to do the
extend/resize.
This is why the older unix guys always seperate stuff from / which could
fill up the root file system. ;)

Maybe a specific ip in /etc/ssh/sshd_config ? And the Network is not up?

Re: [CentOS] Any chance to get a working, current openldap srpm/rpm for centos 5.5

IT-Koordinator:
Hello,
is there anyone out there, who has a current 2.4.23 srpm or good how to
compile it from src with supported db4?
Well, you would have to rebuild half of the system to do that.
If you try to rebuild db4 you should rebuild rpm and so on.
if you rebuild openldap all the ldap client software an dependend stuff
should be rebuilt to ensure everything is working.
What would you do with that rpm? Would it be for production?
Or just for some testing?

Re: [CentOS] nfs slow?
Am Mittwoch, den 10.12.2008, 20:07 +0100 schrieb Davide Cittaro:
Hi all, I'm migrating from Gentoo to CentOS... I'm experiencing a
rather low performance in NFS r/w (as client).
I am not the Linux Expert when it comes to the nfs implementation,
but you should try two things:
1.) Nail Linux to use nfs v3 (imho mount option nfsvers=3)
2.) Use TCP, UDP Transmits are often slow these days. (mount option tcp)
NFS server is solaris (which exports zfs volumes via nfs). The very
same exports were mounted with the same parameters (auto,nosuid,exec)
on gentoo and centos server (bot x86_64)... It happens that centos is
5-10 times slower either in read and write operations... Ok, I'll try
to tune rsize and wsize, but does anybody have an hint on this low
performance?
Maybe gentoo uses v3 per default. We have made great improvements at our
site with these mount options.

One Key Fact for UDP being much faster then TCP was
a.) The Lack of performant Hardware
(CPU Time was expensive and should not be shared for IO/Interrupts)
b.) The Lack of a performant Networkhardware
(Modern Hardware does offload TCP Flow to the Adapter, uses Jumbo uses
Jumbo Frames and so on, so the main argument for generating the TCP
Overhead is gone.)
Nowadays you most often have Gigabit Ethernet Cards and can use Jumbo
Frames with TCP. This often results in higher throughput rates.
On a High Performance Maschine NFS over TCP has the ability to have
somethling like Flow Control which helps when the Server is 1Gbit+ and
the Client only 100Mbit :) Or the other side around.
For us Jumboframes and TCP was the way to go.
Hmm, care to share any references for this?
I'd be reaching for NFS over TCP in a long-haul type environment,
but would run it over UDP otherwise.
