dtm
what version of FC will centos 4.4 be roughly equivalent to in terms of binary compatibility or whatever?
range
The same as 4.3, 4.2, 4.1 and 4.0
dtm
oic
someone was saying, though, that it would have some newer libs
is that not true?
range
Like what?
dtm
a newer libstdc++
i think they said 3.4.6
range
Yes. gcc seems to move from 3.4.5 to 3.4.6.
dtm
so why is that? is that an isolated account?
range
Ask RedHat.
Bugfixes, probably.
dtm
k
well they'd put bugfixes backported into 3.4.4, wouldn't they?
         

range
The reason should be in the release notes.
dtm
k
range: i find it quite odd that the rpm for jahshaka require glibc++ 3.4.4 or 3.4.6 and won't work with 3.4.5
so mean
and that even though these RPMs are made for FC4, fc4 doesn't come with 3.4.4 or 3.4.6
ChiTo
Hy everybody
I have a cluster with /var/lib/mysql shared with GFS but i cant start simultaneously mysql
i have read that i need enable --external-locking and disable the skip-locking from mysqld_safe
but i get InnoDB: Unable to lock ./ibdata1, error: 11
InnoDB: Check that you do not already have another mysqld process
InnoDB: using the same InnoDB data or log files.
does somebody have experienced an installation with GFS and mysql ?
Evolution
ChiTo: you REALLY don't want to do it that way.
ChiTo: your best option would be to set up a mysql cluster, rather than sharing the data files
table locking and other operations will make sharing the mysql data files a nightmare.
ChiTo
Evolution, even if i use GFS?
Evolution
has nothing to do with the filesystem. has to do with application operation and sanity.
ChiTo
Evolution, suppusly for that is GFS no? i can share my data with this filesystem
Evolution, mhh ok, then the locking is made by mysql and not by GFS
Evolution
correct.
ChiTo
Evolution, even if GFS can support flock() ?
Evolution
you're dealing with an application limitation I believe.
not a filesystem one.
ChiTo
Evolution, so the only environment i can make is failover with cluster suite from redhat or mysql-cluster is it right?
Evolution
I believe so. I don't do much cluster work beyond DB clustering.
bobnn
no cluster-f***ing?
you'll never convince me of that

dtm
my app wants GLIBCXX_3.4.4 so i installed libstdc++-3.4.4 from FC3 just for fun and ran 'ldconfig' and it still won't run. why is that?
is libsigc++ supposed to help that? coz libsigc++-2.0.6 doesn'.

i have installed new kernel on my centos server
my boot loader is lilo
how do i test new kernel for one time
because this is remote server
some thing like grub - savedefault --default=0 --once
same thing can be done with lilo ?
Horvath
Installed 4.3 server cd and everything was working fine, did a yum update and now when trying to boot I'm stuck at "ENABLING IO-APIC IRQs"
Something to do with 2.6.9-42.0.2.EL cause 2.6.9-34.EL works fine
Adding noapic to 2.6.9-42.0.2.EL seems to have worked. Still confused tho.
ZBandit
has anyone had and network issues with the new kernel release?
MiK[3]Zz
what i need to install centos? and what options do i have please?
ZBandit: can you help me?
Horvath
MiK[3]Zz: what is the problem you are having?
MiK[3]Zz
i dont know how to isntall centos, if download only server cd, or only a livecd, or all bin cds...
         

Horvath
MiK[3]Zz: Depends on what you need.. If you want a desktop system with a GUI interface then download the 4 bin cds.
MiK[3]Zz
and no livecd?
Horvath
MiK[3]Zz: Not unless you want a livecd
MiK[3]Zz
ok
and server cd is ...?
ZBandit
for a server
Horvath
MiK[3]Zz: Text mode linux, for running a web/email/etc
ZBandit
meaning, you want to run a server.
MiK[3]Zz
so
if i download 4cds, it will be less security desktop, and when server cd, it will be a server?
i am not newbie, but dont understand these cds :)
Horvath
Server CD is a very minimal installation with no GUI
ZBandit
I just got to ask... if you're not a noob, why do you not understand the cd distro?
Horvath
and the packages you would find yourself running on a server like apache, samba, mail
ZBandit: I have not noticed any network issues with the new kernel but have noticed I need to run with noapic in grub boot options
ZBandit
I saw the apic errors as well.
my network error is rather strange.
the system will run fine, and at any given moment, the network connectivity simply stops. No errors in any logs. It's almost as if the gateway dies.
Horvath
mmm
ZBandit
it ran for 20 minutes, and it ran for 20 hours and it ran for 2 hours.
went back to the older kernel and no problems yet.
MiK[3]Zz
ZBandit: maybe due to that, i thought RHEL4 is a GUI
and centos should be the same as RHEL4 without support
Horvath
I'm using a gigabit RTL-8169, no problems as of yet but ill watch out for it.
ZBandit
I even switched to the other ethernet port thinking that maybe the port went bad.
MiK[3]Zz: yes.
I've got 2 machines doing the same thing. Both are fairly close in config.
MiK[3]Zz
ZBandit: btw, for example, now i am using gentoo, which uses 49M livecd, and i have created my server, which have no GUI and desktop with GUI, both from 49M
ZBandit
on the other hand, my other 6 machines are running fine.
MiK[3]Zz
so i am asking, sorry, if i am ...
ZBandit
MiK[3]Zz: gentoo isn't the best OS for someone that is fairly new to Linux.
MiK[3]Zz
huh?
am i new to linux?
Horvath
ZBandit: Check the bug track for anything on the network card you are using
ZBandit
if you want a good clean live cd, I suggest knoppix.
MiK[3]Zz
ZBandit: omg, i am not new to linux
ZBandit
Horvath: tried that too. I mean NO errors are reported.
MiK[3]Zz
check what i wrote
i am using linux at least 3 years and tried a lot of distros
i want centos/rhel/fedora only for testing due to the SELinux
ZBandit
MiK[3]Zz: centos is far more stable and fedora.
MiK[3]Zz
yes, yes, i know that
because of that, after downloading all cds of fedora, heh, i am here to download centos
;]
and in in my imagine, that RHEL4 is OS for server, which have GUI
and targeted policy then
or without GUI with strict policy
you can mix it, but it's more difficult then
i am just using SELinux on gentoo machine and want to try SELinux with new ref-policy to try strict and targeted at all...
klink
I recently downgraded my box from Centos 4.3 X86_64 to 32 bit...for some odd reason one I cannot use cpuspeed to throttle down the speed
OmiKrOn
hi all
any ideeas what is the number of CPU/RAM limitations on CentOS?
ZBandit
klink: and you want to slow down the cpu for what reason?
OmiKrOn
anyone?
donavan
OmiKrOn: there isn't really a limit
why the question?
OmiKrOn
because of this http://www.redhat.com/rhel/compare/server/#note4
Isaia
i need this hor dependencies for a software i need to install
OmiKrOn
i have to build a HA/Balacing cluster for a service that will have over 1 bil hits/day. AS RSs Del 6800 will be used with quad 64 bit d-core Xeon procs and 64 Gbs of RAM
Isaia
libcrypto.so.0.9.7
where i can het this ?
get
OmiKrOn
Isaia: isntall openssl
donavan
OmiKrOn: you'll be fine
Isaia
mysql-libs ?
AlienBlood
OmiKrOn: that's still only 8 CPU cores...you should be ok with Cent
Isaia
yum install openssl ..: Nothing to do
OmiKrOn
donavan: is that specified somewhere in the docs?
donavan
probably not
Isaia
http://pastebin.com/776983 i do not know where to get all those ... can someone help please...
donavan
learn to use yum
OmiKrOn
uhhh. why do you run a hub w/o having the slightest linux skills?
you have any ideeas the number of hack attempts/hour?
Isaia
hmm
thank you
i't wasn't the answer i was looking for .. but still :)
klink
ZBandit: heat, powersaving, etc...I'm running passive coolers on some CG stepping opterons...they used to sit happily at around 32C...now they're hovering around 55C
donavan
use the 64 edition of centos
findme
du -sk . reports 27340 , would i be right in saying that the files in the directory have a total size of 27 MB.
OmiKrOn
donavan: another question, can CentOS be used as a replacement for RHEL AS?
klink
ZBandit: It's quite odd, looking in dmesg it shows the second cpu with any throttling states
donavan
OmiKrOn: the restrictions RH places are purely licensing issues
CentOS is the for all intents and purposes the best of workstation and AS
OmiKrOn
hrm.. is that an official answer? are you an official? :)
donavan
findme: approimately 27M
ZBandit
I'm an office (pain in the ass) and I agree with donavan, hence the reason why I run 18 CentOS boxes.
donavan
OmiKrOn: not sure what you mean by official answer
only your situation can dictate if CentOS is a suitable replacement for you RH AS installs
OmiKrOn
Look, i need to be sure about this ok? I really do not have time to test back and forth, this sh*t just has to be moved from windoze allready it is way to costly to be maintained
s/to\ costly/too\ costly
donavan
centos will run on any box that RHEL 4 AS will run on and it should run the same
findme
donavan, ok thanks. ls -l lists 34 Gig files and there were about 10 of them so total should be 340 Gig, however du reported only 18 Gig, it was tru 64 though. Thanks .
OmiKrOn
donavan: thanks alot
