Mark, I will try again using RO only in parmfile. I create tape using VM and followed instructions showed in IBM Redbook Linux Distributions.

Then, I went to ftp://ftp.us.debian.org/debian/dists/woody/main/disks-s390/current/vmrdr and got the kernel.debian file from there. That worked much better, since I am using VM. The other files there are simply symbolic links to the /tape/ directory, so the only thing that is different is the kernel. So, for VM usage, get the kernel from /vmrdr/. I don't really know why the kernel from /tape/ isn't working in LPAR mode. Mark Post -Original Message- From: Carlos A.

Re: SLES7 mmap problem on s390
Bob: Did you test this with one process accessing the file? In your description of the problem I got the impression that you didn't. The problem occurs when multiple processes have the file mmaped. What version is your kernel? 2.4.7-SuSE-53 kernel. In case you didn't know: the truncate will not cause any space to be allocated to the file. There must be more going on here then just marking the page dirty, otherwise there would be no place to write the dirty page. It is definitely the incorrect calling of writepage that is causing us problems. Like I said, we made a patch to ext2_writepage() and even without a file with a hole, linux writes to it when it shouldn't.. The more I think about this, the more I think this may be intentional. The mmap data may need to be backed someplace. When it's mmapped PRIVATE READONLY, it shouldn't. It doesn't on other kernels. Anyone: I would be interested in knowing if this problem can be reproduced on another architecture. Can anyone test this on a PC with the same version of the Linux kernel? I know it doesn't happen on a kernel.org 2.4.7 kernel on a PC. I haven't tried it with this specific kernel on a PC though... That would give me a clue if it's in the architecture dependent code or not. Good Idea.

I then use the insmod command to load qdio.o and qeth.o followed by ifconfig and route command to get the Linux virtual machine on the network. If you are using insmod on qdio then qeth then you are resolving the module dependencies yourself. I suspect if you tried modprobe qeth (without loading qdio) then you might run into the same problem. The table of module dependencies is per-kernel-version-tree. You'll need to run a depmod -a to rebuild the dependencies for a new kernel. You may need to fiddle with explicit options to depmod to ensure you build the dependencies for the right kernel and put them in the right place. Look at the man page for depmod for details. Often, distributions will run an automatic depmod sometime during boot. This normally removes the need to do a manual depmod but equally makes it easy to forget when one *does* need to do one. --Malcolm -- Malcolm Beattie [EMAIL PROTECTED] Linux Technical Consultant IBM EMEA Enterprise Server Group... ...from home, speaking only for myself
Re: SLES7 mmap problem on s390
Ext2 lets the stuff get written to disk because it assumes linux won't mark pages from files in a RO filesystem dirty. Since ext2 assumes this, it doesn't bother to check in ext2_writepage(), which is perfectly sensible. It just happens to be wrong in this case. -Ben On Thu, Jan 30, 2003 at 12:56:30PM -0800, Fargusson.Alan wrote: This is very curious.

Re: SLES8 Install problem
Ah! Success! My problems of not finding enough space are solved! At SuSE's suggestion, I tried to copy the CD to my windows machine and it failed. That led me to flip it over and notice some scratches. Some rubbing on my sweater fixed the problems. It's now mounted over Samba and installing away. I guess us mainframers need to get used to this new shiny media... SuSE is still having problem with registration codes which are not stuck to the install package anymore. They tell me that should be worked out soon and in the meantime aren't shipping any SLES8 CD's out unless absolutely necessary. Thanks Dave and everyone for helping! This list is great.

Umm, no.

Re: Network Configuration for Linux....
The problem is I tanked this guest by altering the modules.conf, route.conf, rc.config, and chandev.conf. By the way, we are running SuSE 2.4.7 under z/VM 4.3.0. The setup was running VCTC, but I somehow messed that up making the changes. I've been trying to find a way to edit via the 3270, since I can't get back in via telnet. I made a rookie mistake of not backing up the originals. Any assistance would be great.

LeMarr, Ok, first, check to see if the CTC driver is loaded: lsmod If not, load it: modprobe ctc Make sure it finds the correct device numbers, and assigns the read/write channels properly. If not, you'll be learning a few sed commands. :) dmesg | tail Set the ip address ifconfig ctc0 111.222.333.444 pointopoint 555.666.777.888 Set the default gateway: route add default gw 555.666.777.888 netmask 0.0.0.0 Theoretically, at this point you should be able to telnet in again.

Re: Network Configuration for Linux....
I'm able to login to the machine (Linux Guest) but only via the 3270. Meaning, I login at the z/VM Console as the Linux Guest. I can then logon to the machine as root, but you see this session is for 3270 and has problems when I try to vi and such. I can issue ifconfig and netstat, but I can not do any editing from this session - that I know of. -Original Message- From: Rob Schwartz [mailto:[EMAIL PROTECTED]] Sent: Thursday, January 30, 2003 6:02 PM To: [EMAIL PROTECTED] Subject: Re: Network Configuration for Linux Do you have a command line editor like ed???

Re: Network Configuration for Linux....
LeMarr, ed is a very simplistic line editor, with arcane syntax/commands. It will work on a 3270. If you have Linux installed on another system where you can do a man ed then go ahead and give it a try. If not, then I would seriously recommend using the commands I sent you previously to try to get your network back up, and then use YaST to make the fix permanent.

LeMarr, Don't forget to get back into YaST and make the corrections permanent. The commands you executed are dynamic, and will not persist across an IPL.

Re: Network Configuration for Linux....
LeMarr, ... The problem is not that you're on a 3270 session but that on that 3270 session you're getting line-mode interaction with the guest operating system. Linux/390 now has (thanks to the kind folks at UTSGlobal) a 3270 driver. Sadly, none of the full-screen text-mode applications have any way of using that interface. Many (most?) could be easily re-tooled to use a block mode subset of the ANSI X3.64 protocol (roughly what is used for VT100 and 'xterm' and many others) if only there were a protocol converter. We need the opposite of a 7171, something like a TNVT100 for local. So ... this much I'm sure you already know. It's as if you were on a DECWriter terminal. Use 'ed' or other line-mode methods. Another solution would be to attach this guests root disk to another Linux guest (one NOT having network trouble), mount it there, do your work, unmount it detach it then re-connect it to the troubled guest. -- RMT
