netstat, /etc/hosts

2004-11-02 Thread Istvan Nemeth
Hi!

I have suse9 and suse8.
Internal ip adresses are resolved with /etc/hosts, not nameserver.
In suse9 the netstat can find these hostnames, but in suse8 it doesn't
works, except when I write ::: prefix to every IP address in the
/etc/hosts file!

Why is it so, and how can I shut down ipv6??

Thx
Istvan

Re: Installation of SLES9 hangs on 'creating initrd'

2004-11-02 Thread Michael MacIsaac
Doug,

 After using these scripts my installation continues to hang on 'creating
 initrd' at 62%.  Did I do something wrong?

Hmm, if you got past the copying of the RPMs from the install tree to your
new system, then I would guess the problem with creating the RAMdisk is
not related to the install tree.

How large of a virtual machine do you have?  256M or better for install -
smaller than that may be an issue.

Another thought is what type of network connection are you using?  Most
people are not running into this problem, so somehow your install might be
adding different modules to the RAMdisk, which might be causing the
problem.

Also, what hardware are you using?

Determining what tasks own pages in swap?

Is there a way to determine what is allocated to swap? I have an WebSphere
image where it behaves itself for a while, but typically seems to grab
300-400 meg of swap space over night. Not consistently also. I've bumped
the memory a couple times but that only seems to increase the amount of
cache that is being allocated. Problem isn't happening during the work day

 Using option 2 OSA Ethernet
What type of OSA card is it (OSA express Fast Ethernet)? Is the OSA
defined as type OSD or type OSE? If it is type OSD which is more common
for recent OSA cards, did you try using option 3?

Actually the question may be moot, because you probably cannot use the
qdio driver (for type=OSD OSAs) with a type=OSE CHPID (which uses the
lcs.o driver). If this is the case, there may be a bug in installation
process.

Has anyone else installed SLES-9 successfully with option 2 and a type=OSE

I hope you already sorted this out - my reply is a bit late now.

 I don't know how to set back the local time automatically.

Things will work automatically. The /etc/localtime file defines the
time zone, the offset to UTC for each of the time zones, and then
moment where you cut over. The /etc/localtime is normally a copy of
the correct timezone from /usr/share/zoneinfo.

 I don't want to set the time manually (or with network tools): Linux can
 keep the right time, and so LPAR-s times are the same.

You hardware clock runs UTC, and does not get changed with DST. Linux
obtains the TOD clock with the STCK instruction and computes local
time from that UTC timestamp using the /etc/localtime definition. It
will automatically do the cut-over. I had a loop run 'date' each
second and look what happens:
Sun Oct 31 02:59:57 CEST 2004
Sun Oct 31 02:59:58 CEST 2004
Sun Oct 31 02:59:59 CEST 2004
Sun Oct 31 02:00:00 CET 2004
Sun Oct 31 02:00:01 CET 2004
Sun Oct 31 02:00:02 CET 2004
My loop was also creating a small file each second, and even that works:
linux10:~ # ls -l --time-style=full-iso file*
-rw-r--r--1 root root   30 2004-10-31
02:59:57.0 +0200 file60.tmp
-rw-r--r--1 root root   30 2004-10-31
02:59:58.0 +0200 file61.tmp
-rw-r--r--1 root root   30 2004-10-31
02:59:59.0 +0200 file62.tmp
-rw-r--r--1 root root   29 2004-10-31
02:00:00.0 +0100 file63.tmp
-rw-r--r--1 root root   29 2004-10-31
02:00:01.0 +0100 file64.tmp

So it looks like the filesystem is nicely keeping track of the
timestamp and the time zone when the file was created.

Re: Best Practices EVMS FCP Multipathing

Hi Cameron,

you definetly want to do multipathing with FCP. Unlike with FICON, your
adapter (and your physical fibre) will be a single point of failure if you
don't. In order to maximize performance, you can combine multipathing with
raid0 striping to gain further.

Greetings,
Just a few Questions reguarding FCP Multipathing. I have installed
multiple systems with a 5 GB LUN for the / system and am wondering if it
is a good idea to define this with multipathing, or is it better to add
more disks to the mix and multipath those that are only  used for say
databases and such? What is the best practice for this. Is it a good idea
to have multipathing on your root volume or not? Novell does not seem to
know either. They are hinting at the idea a bit that there would be more
problems if you had the root volume setup with multipathing. Any ideas?
What do you think? Has anyone had any experiences with this that they
would like to share?

Re: Determining what tasks own pages in swap?

2004-11-02 Thread Carsten Otte
Hi Jim,

I think you may be mislead by the statistics that Linux shows. A lot of
allocated  swap does only mean that part of your application got swap
slots assigned to it. This can happen for example when your application is
idle (does nothing) while updatedb runs at night. The swap slots remain
assigned although the application resides in memory again, therefore a lot
of swap used being reported does not always mean that large parts of
your application does not fit into memory.
What you really want to look at is the swap rate when workload is running
(vmstat reports it for example). If your swap-in and swap-out rates are
low during the workday, you do not have a problem at all.

with kind regards
Carsten Otte

A generic suggestion to check is that nothing has duplicate IPs.  I've done
this before by accident and caused no end of confusion until I tracked it
down.  You'll see intermittent behavior like that due to ARP wars where
each system tries to own the IP, and it depends on the local ARP cache of
the system you're connecting -from- which one gets picked.

This is also relevant for gateways - if you bring up two gateways with the
same IP, everything on the network that routes through that GW is going
to have the same intermittent issue (but not, of course, the same systems

My experience may be of help here.
I have seen lock-ups in my Linux LPAR. In this case it was drastic and I
had to bounce (ouch!) Linux. I found that there was a perl script that was
gobbling memory, forcing other processes to be swapped and the swap space
ran out. When the LPAR had 1GB memory, this problem was masked. When the
memory was reduced to 256MB (we gave the rest to IFL) this problem was
unmasked.

I used the 'top' to track the rouge process.

 Greetings,
 I am having a strange issue with my linux guests. When i login to one
and start working on it for awhile it then stops responding. It is like
someone unplugged a network cable from me and i cannot communicate. Then
when i login to another system it works just fine, but after a bit it does
the same thing, but then when i go back to the first one that failed it is
back online again. What is happening here? Has anyone had this issue
before? I think i am having this issue explained in this document here
from IBM.

 What do you all think?
 Is this the same issue?
 We don't have these PTF's applied and we are running z/VM 4.4.

How big are your Linux guests?  How much real storage do you have?

How big is each guest?  My guess is that your guests are way too big,
and they're getting stuck trying to all get paged in at once.
