Re: Start DB2 Connect at linux boot

[Tom Huegel]

 Last update.
Well it has been a learning experience - thanks to all the teachers.
Here is what I learned.
1) I didn't have to change anything it was all setup.
2) /etc/inittab is not in the picture in SUSE 12
3) All I really had to do was configure and start the DB2 Fault Monitor.

A) Start up the fault monitor daemon:
root@host01: /opt/ibm/db2/V11.1/bin> ./db2fm -i db2inst1 -U

B) Start up the fault monitor service:
root@host01: /opt/ibm/db2/V11.1/bin> ./db2fm -i db2inst1 -u

Note:
The above command may return a non-zero return code:
root@host01: /opt/ibm/db2/V11.1/bin> ./db2fm -i db2inst1 -u
./db2fm return non-zero rc, please see log file
'/opt/ibm/db2/home/db2inst1/sqllib/db2dump/db2diag.log'
This is because the DB2 instance is already started. Stopping the instance
and proceeding to run the same command succeeds.

C) Turn on the fault monitor for the instance:
root@host01: /opt/ibm/db2/V11.1/bin> ./db2fm -i db2inst1 -f on

I GOT IT!
I think these two files are the key.
 cat /etc/inittab

updated

[Unit]
Description=DB2 v11.1.2.2

[Service]
ExecStart=/opt/ibm/db2/V11.1/bin/*db2fmcd*
Restart=always

[Install]
WantedBy=default.target

Thanks EVERYONE

Start DB2 Connect at linux boot

[Tom Huegel]

I'm a LINUX novice. I need to have DB2 CONNECT autostart at LINUX boot
time. How do I do that? LINUX is SUSE.

Re: Redbooks Rumor

[Tom Huegel]

I too have been a long time redbook user and can't imagine what the
internal politics were to kill one of the best resources users had...
Although I have always wondered why BigBlue called them RedBooks instead of
BlueBooks.

KVM question.

[Tom Huegel]

This has probably been discussed quite a bit but I wanted to ask for some
real user feedback.

I have a customer that is interested a POC of z/VSE zLINUX VTAPE.
Unfortunately they do now have z/VM so the zLINUX would have to be in an
LPAR. So the question is 'do I gain/lose anything using KVM as the
hypervisor in the zLINUX LPAR?'.

Thanks
Tom

zLINUX and z/VSE

[Tom Huegel]

I don't know if this is really a question or just a thought.

I have a customer that recently installed a new z/14.
They are a relatively small shop, they currently run z/VM and a couple of
z/VSE guests.
The z/14 has an IFL.

The manager asked me 'what can we do with that IFL?'
I thought I'd ask here if anyone was using z/LINUX guests to support z/VSE
in some way. If so, what are you doing?

I'm just looking for ideas, I don't have an immediate problem that I am
trying to solve.

Thanks,
Tom

Re: The Mainframe vs. the Server Farm: A Comparison

Don't forget to consider the mainframe has a much smaller enironmental

The cost savings in power comsumption, air conditioning, and floor space
can be huge.

Re: UBUNTU on HERCULES

[Tom Huegel]

Thanks Mark I'll give that a try when I get the chance.
Also I was looking at Hercules 4.0 and there is a new parm 'ARCHLVL' that
is a replacement for ARCHMODE and has more options for setting the machine
architecture bits. The only binaries are for windows (I don't have a
windows machine) but maybe I can following the instructions and compile the
source for LINUX.
I probably won't get back to it until next week.

Re: UBUNTU on HERCULES

It looks like this is not a totally new problem. I googled STFLE and had
several hits the problem showed up in 2009 concerning z9-z10 machines.
Here is the link if anyone cares to read it. It is informative although not
conclusive.

Re: UBUNTU on HERCULES

Thanks Mark,
I'm telling Hercules it is s z13 (2964 N30) but I don't know that Hercules
does anything with that other than reflect it in the STSI instruction...
How does UBUNTU determine the hardware level?

UBUNTU on HERCULES

[Tom Huegel]

I am having a problem trying to install UBUNTU s390x on Hercules.
Hercules is 3.11 on OpenSuse LEAP 42.x 64-bit.
The error I get is "The Linux kernel requires more recent processor
hardware."
HHCCP011I CPU: Disabled wait state
PSW=0002 8000 BAD

Is there a minimum Hercules requirement?
Or is it something I might find in the Hercules config file? I have z/ARCH
specified.

Thanks for any help or suggestions.
Tom

OpenSuse Available?

[Tom Huegel]

A colleague mentioned that OpenSuse was available for s390x but I can't
find anything on the OpenSuse website. Google searches were inclusive.

Is OpenSuse s390x available somewhere for download/installation on z/VM
system?

Thanks

If you are z/VM you can use TRACKWRITE (currently in the authors edition)

Re: Simple DASD question

[Tom Huegel]

So far I have failed with my feeble attempts to add the second disk dasdb
(0251) to the btrfs filesystem.
This is what I have fresh after my re-re-re-re-install.
It seems "btrfs device add /dev/dasdb1 /" would be a good thing to do but I
get message about dasdb1 not existing...

Re: Simple DASD question

[Tom Huegel]

I don't know.. I've done a couple of re-installs and I still don't
see dasdb (251) being used.
This is SLES12 SP1. I activate and format my two drives and then take all
of the defaults.

But I have no idea if 0251 is actually used.. How can I see if it has

Simple DASD question

[Tom Huegel]

I am sure the answer must be simple.
How can I tell if a disk (3390-9) is actually being used?

Background:
I just installed SUSE 12 specifying 2 3390-9 on the installation panel.
I tried to add a package and I get 'no space on DASD' condition.
I am guessing the installation only used the first disk, but how can I be
sure?
Assuming I can determine the second disk is unused I should be able to
extend the LVM to it and my problem would be solved. Right?

Thanks
Tom

Re: ? FTP permissions on FEDORA ?

[Tom Huegel]

I am just thrilled we got it working today . I have been working on this on
and off for about three weeks.
I'm an old z/VM (VM/370) guy and can get very confused with LINUX..

Again my thanks to everyone who helped.

? FTP permissions on FEDORA ?

[Tom Huegel]

Background:
I have FEDORA F23 running and it is working well.
I want to use this as a FTP server for installing other distros ,, RedHat
and SUSE.
I've downloaded the ISO's from the respective vendors.

On F23 I have started vsftp, stopped the firewall, created a directory in
/var/ftp/ called linins, mounted the ISO's there, chmod a=rwx
/var/ftp/linins

Everything looks good.
>From CMS I can FTP to the directory and download files.

The Problem:
When I try to install either of the other OS's I get this error message:
" server denied you to change to the given directory"

My path looks something like this:
inst.repo=
ftp://root:mypasswordt@172.17.51.126/var/ftp/linins/rhel-server-7.2-s390x-dvd.iso
 <==RedHat

Any ideas what I am missing?
Thanks
Tom

Re: LINUX SSH problem.

/etc/securetty: No such file or directory

This one didn't work.
we sent a password packet, wait for reply
debug1:* Authentications that can continue:

me?
Permission denied, please try again.

This one (to a different server) worked.
we sent a password packet, wait for reply
debug1: Authentication succeeded (password).

Re: LINUX SSH problem.

[Tom Huegel]

Yes I do login as root always have, it works fine everyplace else.

selinux=0 is in the boot messages.

A possible clue - I can start VNCSERVER from the VM console but again when
I try to VNC to the server, again it gets rejected.

Re: LINUX SSH problem.

[Tom Huegel]

I have the latest PUTTY, but just for kicks I downloaded a different SSH
client. Same results.

Re: LINUX SSH problem.

[Tom Huegel]

I wish I had some idea of what I might have changed. Intentionally I
haven't changed anything.
There are no new messages in the /var/log/messages file after a failed
logon.

Comparing /etc/parm.d/sshd to another system that allows SSH logons ...
they are identical.

LINUX SSH problem.

[Tom Huegel]

This seems strange to me (a LINUX novice) but I have FEDORA f21 system that
has been working fine until recently.
It seems strange LINUX starts up just fine but when I try to SSH
(Putty) into it I get the initial logon screen but the password is always
rejected.
>From the z/VM console I can logon using the same password.

I must have touched something *&&*&%.
Any idea how to fix it?
Thanks
Tom

When I try STARTX I get:

Use the -- option, or make sure that /usr/bin is in your path and
that "/usr/bin/X" is a program or a link to the right type of server
for your display.  Possible server names include:

Re: Curious about crash.

[Tom Huegel]

My ignorance overflows..
When I look on my INTEL LINUX I can find grub.cfg in boot/grub2 but I
cannot find it in the zLINUX.

ls /boot
bootmap symvers-2.6.32-573.8.1.el6.s390x.gz
config-2.6.32-431.el6.s390x System.map-2.6.32-431.el6.s390x
config-2.6.32-573.8.1.el6.s390x System.map-2.6.32-573.8.1.el6.s390x
grubtape0
initramfs-2.6.32-431.el6.s390x.img  vmlinuz-2.6.32-431.el6.s390x
symvers-2.6.32-431.el6.s390x.gz vmlinuz-2.6.32-573.8.1.el6.s390x
[root@tom129 /]# ls /boot/grub
ls /boot/grub
splash.xpm.gz


Two additional points: 1) I'll post my XCAT experience as best I can
remember, but probably not until I return from the holiday break in
January. 2) I wrote up the little exec (pipe trackread) I had mentioned to
compare raw dasd tracks but I couldn't determine the problem because there
were too many differences.. But if anyone would like the exec I can post it
here.. Someone may have a use for it.

Why these LINUX machines are setup the way they are is a mystery to me. As
part of the lab exercise I used XCAT to provision the machines..

Following what Rick said I was able to boot the failing machine.. I don't
know what to do next, but it is booted.

Re: Curious about crash.

[Tom Huegel]

Like I mentioned earlier this is not production system that is down. It is
just a lab system that can be re-installed easily. It would be nice to have
some idea of what killed it in the first place.
Using DITTO I was visually trying to compare the DASD from the working and
nonworking systems, but that was inconclusive. If I get a chance later I'll
write a quick PIPE to do trackreads and compare the two disks, maybe
that'll show something.
Thanks for all of the tips and comments.
Tom

Right the kernel appears to be different.

Curious about crash.

[Tom Huegel]

I have 2 lab z/VM guest machines both are RHEL 6.5, one registered one not
registered. I recently ran 'yum update' on both and all seemed to go well
until I did a reboot.
Now the registered machine fails to boot, the other one works fine.

I'm probably not going to fix it (unless someone sees an easy fix) I am
more curious as to whether I did something wrong, or any guesses as to what
happened.
Anyways here is the last few messages:

FEDORA 23 install issue

Re: FEDORA 23 install issue

[Tom Huegel]

Dan/Jan,

I tried Jan's suggestion and replaced
root=live:
https://dl.fedoraproject.org/pub/fedora-secondary/releases/23/Server/s390x/os/images/install.img
with:
inst.repo=
https://dl.fedoraproject.org/pub/fedora-secondary/releases/23/Server/s390x/os/

Now it is working..
Thanks

FEDORA F23 and KDE

[Tom Huegel]

When I try to do this:
[root@fedora ~]# dnf groupinstall "KDE Plasma Workspaces"

I get this:
Last metadata expiration check performed 2:55:39 ago on Tue Dec  8 14:04:18

I searched but can't find any clue as how to fix it.

Any ideas?
Thanks

Re: Changing SSI cluster name on z/VM

[Tom Huegel]

There is a package on the IBM VM download "RENSSI" that you might want to
take a look at. It's purpose is not to change the cluster names but to
change member names. There may be some useful information there.

Re: HYPERPAV problem RHEL6.5

[Tom Huegel]

Thanks for the responses.
My problem was with the sequence of events.
I was doing dasdfmt of the base after attaching the devices (base and
aliases).
Then I thought just chccwdev -d and then chccwdev -e would be enough.
What I needed to do was after dasdfmt to attach (detach first if necessary)
the aliases.
Then I see what I expected.

 Do you have both a base volume _and_ an alias from the same pool attached
 to the Linux guest?  Are they both online from the Linux perspective?

Re: Creating an accessible disk

[Tom Huegel]

Here is an example.
In your directory you have a MDISK statement similar to this one.
 MDISK 191 3390 2540 0020 USRVOL MR READPW WRITEPWMULTIPW
Your students will need the following.
LINK youruserid 191 192 RR   -- this can either be in their directory or
in their profile exec or they can enter it manually
  if it is in the
profile exec or entered manually they will need the readpw (READPW)

If entered manually they will also need to access it. ie ACC 192 D

Your requirements as far as mini-disk addresses and access mode may be
different.

I hope this helps.

 You will have an MDISK entry for the disk in your directory entry.  They

 If you ATTACH a volume to your ID, no one can LINK to it and no one else
 can ATTACH it.

Re: Adding Memory Question

[Tom Huegel]

Just change the directory entry for your sandbox LINUX to something like
this.

USER zlinuxname zlinuxpass 4G 4G  G

Don't worry too much about the performance for now, that can always be
tuned later.

If you don't know how to edit the directory come back and I am sure someone
can walk you through it.

BTW you can use the INDicate command to see z/VM utilization and paging
numbers.

 Hi Matt,

 Couple of questions.

 1. You mention your servers were intended as a sandbox. Does this mean you
 can shut down the intended server?
 2. Does your z/VM LPAR have real memory to give?

 The easiest way to add more memory would be to shutdown the intended
 server, add more memory to the server's USER DIRECTORY on z/VM, and restart
 the server.

 There is a way to dynamically add more memory to a running server if you
 can't shut down the server and memory had already been set aside prior.
 The command 'q stor' on your z/VM system will show how much memory the
 LPAR has defined.

 Good luck

 Hi,

 Firstly a specific question:  I believe that the disk pool used by XCAT
 for its ISO images is completely different to the one used for housing the
 data used by the cloned guests.  In my case the first pool is called XCAT1
 and the second pools are LINUX27 and LINUX54 (mod-27 and mod-54
 respectively).  Am I right?  If so, a follow-up question - where do I
 specify the latter pools in XCAT?  Nowhere?  Somewhere?  I am missing
 something basic, I believe.  I have the XCAT GUI going and the IVP passes
 all the disk tests.  We are not using CMO yet but expect to do so if
 required (more later if appropriate).

 Now a general observation and a question:  the z/VM v6.3 documentation on
 OpenStack and XCAT is somewhat scattered and perhaps sparse, at least
 compared with the excellent and voluminous documentation on CP, CMS, etc.
  Can anyone recommend a good overview?  I'm reading the SourceForge pages,
 and the z/VM v6.3 manuals, but have yet to find an all-in-one
 zXCAT-Up-And-Running reference.

 SourceForge pages:

 http://sourceforge.net/p/xcat/wiki/XCAT_zVM/
 http://sourceforge.net/p/xcat/wiki/XCAT_zVM_Setup/
 http://sourceforge.net/p/xcat/wiki/XCAT_Documentation/

 z/VM v6.3 manuals:
 SC24-6248-01:  Enabling z/VM for OpenStack (Support for OpenStack Icehouse
 Release)
 SC24-6234-07:  Systems Management Application Programming

 For example, relating to my specific question above, there are references
 in both sets of documents to regions and groups where I was expecting
 terms like SFS disk pool and DASD volume, which I don't believe are
 interchangeable, and hence my need for a beginner-type doc.  If they are
 interchangeable, it's not obvious to a young player (not that I'm young,
 just a noob).

 As mentioned, these are very good and get one going, but appear a bit
 disorganised to this uneducated reader.  Maybe it's a case of DIY doco, but
 I'd like to think not.  Perhaps some training!  OK, enough dreaming.

 Best regards,
 Peter

Re: Iaas - SCO vs IBM Wave vs xCat vs zPro - ZPRO

[Tom Huegel]

If you want to play remember xCAT is a freebie. If you are z/VM 6.3 you
have xCAT and can jump right in.


On Tue, Jan 20, 2015 at 2:08 PM, Barton Robinson 
bar...@velocitysoftware.com wrote:

 zPRO has been out for about 4 years and was a project started almost 10
 years ago.  We had many customers create their own self service
 applications using our web technology, it seemed reasonable to take
 their ideas and make a common product.

 ZPRO V2 is built on ALL native z/VM functionality, meaning, we don't
 have any requirement for Linux servers, agents, SMAPI, JAVA and a lot of
 other things I find frustrating.  KEEP IT VERY SIMPLE (AND VERY
 INEXPENSIVE)

 With our webserver (ZVWS, formerly ESAWEB) being a native z/VM
 webserver, eliminating SMAPI (and anybody who has tried to use SMAPI
 knows that is a VERY GOOD thing) was easy.  No java agents mean any
 browser works.  Since ZVWS is already installed in a few hundred
 installations, most of those already have the full infrastructure
 installed - zPRO installation takes about 10 minutes by a junior systems
 programmer.  It is NON-INTRUSIVE, meaning that if it is there it works,
 if not there, everything functions.  I don't like system hooks or asking
 customers to rebuild lpars because of some software product.

 Next week, our demo system will be back online again with Version 2.
 We've been giving preliminary demonstrations of V2. Most installations
 are asking for self service so you will be able to clone a Linux
 server, a CMS guest, a 2nd level z/VM server AND logon to it.
 Can't provide an external IP address so no SSH in, i can't afford
 someone from say Ukraine or North Korea creating a server on my system
 and hacking the world.

 Watch this space, there is a lot of back ground activity now that will
 soon be very visible.

 And to answer your final question:  ZPRO can be configured to clone a
 server using disk pool A on LPAR1.  Installing WAS is not a mainframe
 thing - but having golden images of your target server means you have
 consistency and a lot less time diagnosing problems.

 Can wave/zPro/xcat be configured and automated to a level where user may
 just say give me redhat 7 created on  disk pool A and on  LPAR 1 and
 install WAS.


 If you would like a demonstration, please do contact me.

 Hello,

 more
 digging I do  then more I am lost.
 There are many presentations out there with big words like cloud,
 orchestrate, cut costs bla bla bla  but it is hard get to the bottom
 of it.

 Correct me if I am wrong but so far it seams that

 1. SCO is rather developed for project managers who can just click and
 deploy without understanding the platform at all. They can just chose
 images, create patterns, add scripts to be executed on top of an image.
 Patterns - who provide these? IBM provides these or user have to create
 their own (for example installation of WebSphere or Apache server after
 deployment).
 It does not support SSI and zFCP  (only edevices)

 2. IBM Wave seems to be more for system admins who are just tired of 3270
 and constant punching virtual kernels. User can do most of z/VM's tasks
 from a GUI and it looks awesome. Admin of IBM Wave have to understand Z
 and
 z/VM very well.  But on the other hand, I see that IBM Wave supports users
 and groups. You can create a non privileged user and give him access to
 only to specific projects.  For example web server. So it kind of looks
 like SCO. If that is the case - why bother with SCO, isn't IBM Wave
 better?
 Am I wrong?

 3.  zPRO. I wish I could find some demo videos about this one. From my
 understanding it is more like an IBM Wave. Designed for system admins not
 project managers. Not meant to be IaaS product right?

 4. xCAT. Also rather for system admins only right?

 When I try to sum it up in my head, it comes out that only SCO is an IaaS
 solution (a very limited but still) because only SCO allows someone who
 knows nothing about Z to deploy a virtual machine and add some software on
 top of it.
 And SCO seems to be using xcat for doing actual system work.

 Can Wave/zPro/xCat be used as an IaaS ? OR those are completely not meant
 to be an IaaS solution.
 I guess I should ask:
 Can wave/zPro/xcat be configured and automated to a level where user may
 just say give me redhat 7 created on  disk pool A and on  LPAR 1 and

Re: Performance Toolkit and zLinux

Although zVPS is a fine product and I am sure well worth the price it
provides much more than the basic information I am looking for.

All I need in my lab on the occasions when someone wants to run a zLINUX
guest is provided by the APPLdata and PTK.
Thanks Berry.

 The RMF agent that runs inside the Linux on System z guest was

 to update the Performance Toolkit handling of that interface as
 other things have changed since the introduction of the RMF agent

 earlier will point to information ont that) that supports z/OS as
 well. There was a statement of direction in 2011 for these changes.

 Performance Toolkit will report on the z/VM Appldata that Linux
 provides on all the current distributions. While this doesn't
 provide process level information, it does provide a Linux view
 of some important metrics. It is also very low overhead.

 Additionally, OMEGAMON XE for z/VM and Linux provides both the z/VM
 and the Linux agents. Perhaps not the first choice for a PoC, but
 wanted to mention for completeness.

Performance Toolkit and zLinux

IBM used to have the RMF module to download for zLINUX so it could be
monitored via Performance Toolkit.
Currently z/VM 6.3 SUSE11 that module no longer available. Is there a

Re: qeth.90d7eb---error SUSE11 install

[Tom Huegel]

Yea Alan, I kind of figured that something like that was going on. I don't
specify any MACID on the NICDEF or any SET NIC commands.
There must be something in the SUSE11 installation script.
I'm using xCAT (z/VM 6.3) to do the provisioning. It all seemed to be
working as shown in the xCAT tutorial (SourceForge) but something is going
on here.

I'll keep digging.
Thanks

 Something is trying to override the CP-assigned unicast MAC address with
 MACPROTECT ON.  Do you have a MAC address specified in your configuration?
  If so, remove it.

Re: qeth.90d7eb---error SUSE11 install

[Tom Huegel]

Thanks Alan you got me thinking.

Here is what I ended up doing.
There is a table in xCAT for mac addresses. What I did was to manually
change that address to match the z/VM assigned address from the NICDEF ..
Then it all worked.

I suppose another, maybe better way would to use the xCAT generated mac
address in the NICDEF statement.

Whatever works..

 Not surprising, as other platforms don't protect the MAC address.

 If MAC addresses are to be assigned, then they need to be specified in the
 NICDEF or via COMMAND SET NIC during the vNIC manufacturing process, not
 at the whim of a some random guest.  Only trustworthy guests that have a
 specific documented need to set their MAC address should be permitted to
 do so.

 IMO, of course.

Re: Which DASD is free

[Tom Huegel]

I wrote a REXX program that reads through a disk (any disk that can be
attached or linked to a CMS vm) and reports what is finds. i.e. VOL1
labels, CMS1 labels, CMS files, gaps between labels, overlaps etc.
It is not the first defense, but I find it helpful to answer the question
'What's On MY Disk?'.
I summited it to the VMWORKSHOP, I don't know if it has been uploaded yet
to their tools page. It's called WOMYD (What'sOnMYDisk).

If not you can contact me and I'll give it to you.

  I spent a LOT of time doing AIX support-- both before p5 hypervisors and

  Is it a physical volume?  (Which, using a hypervisor, may be mapped into
 a
  logical volume, or, via a SAN, is declared physical also despite being
  mapped across one-- or more-- actual physical devices.)
 
  Is it a logical volume?  A logical volume at the hypervisor level looks
  like a physical volume to the instance which likely contains multiple
  logical volumes.
 
  With the abstraction of volumes the way they've been of late, the
 word, I
  believe, is becoming more and more ambiguous.
 
  Though, really, the query for free DASD -- devices -- implies physical
  volumes.
 
  Mind you, with the expanded use of SANs, all bets are off as to where the
  LUNs really map to.

Re: FEDORA F20 boot HCPGIR453W CP entered; program interrupt loop

 Testing the hypothesis on an all-on-LVM F 20 setup, I added

 Then after rebooting, the unit restarts without any

 One has to think the initrd is not getting properly fixed up,
 to be able to access the LVM only setup, so it probably makes
 sense to revise:
 http://s390.koji.fedoraproject.org/test/ks/f20-lvm.ks
 accordingly, pending a fix.  Dan, is there a bug number on
 this?

 ...
 logvol /boot  --size=500 --name=Boot --vgname=Fedora
 logvol swap  --fstype=swap --size=2048 --name=Swap
 --vgname=Fedora
 ...

 Looking at the KS I see also that the swap is going through
 another layer of redirection through LVM, rather than natively
 being placed on the disk.  There are two schools of thought
 here (having swap on LV permits resizing, vs. assumed more
 robust access and performance) but it may make sense to
 migrate it out of the LVM as well

 I moved to a 'file based' swap at '/' but on the LVM thus,
 which permits resizing:

 cd /
 fallocate --length 1GiB RPHswapfile
 mkswap /RPHswapfile

 and amended the fstab and rebooted, without incident

 [root@clef01 ~]# grep swap /etc/fstab
 # /dev/mapper/Fedora-Swap swap  swapdefaults0 0
 RPHswapfile   swap  swapdefaults0 0

 so permitting me to reclaim that swap LV space

  all-on-LVM setup.

 Testing the hypothesis on an all-on-LVM F 20 setup, I added
 to: yum.conf
 a line: exclude=kernel
 and ran updates

 [root@clef01 ~]# grep exclude /etc/yum.conf
 exclude=kernel

 Then after rebooting, the unit restarts without any
 intervention.

 One has to think the initrd is not getting properly fixed up,
 to be able to access the LVM only setup, so it probably makes
 sense to revise:
 http://s390.koji.fedoraproject.org/test/ks/f20-lvm.ks
 accordingly, pending a fix.  Dan, is there a bug number on
 this?


 2. from the ks.cfg:

 ...
 logvol /boot  --size=500 --name=Boot --vgname=Fedora
 logvol swap  --fstype=swap --size=2048 --name=Swap
 --vgname=Fedora
 ...

 Looking at the KS I see also that the swap is going through
 another layer of redirection through LVM, rather than natively
 being placed on the disk.  There are two schools of thought
 here (having swap on LV permits resizing, vs. assumed more
 robust access and performance) but it may make sense to
 migrate it out of the LVM as well

 I moved to a 'file based' swap at '/' but on the LVM thus,
 which permits resizing:

 cd /
 fallocate --length 1GiB RPHswapfile
 mkswap /RPHswapfile

 and amended the fstab and rebooted, without incident

 [root@clef01 ~]# grep swap /etc/fstab
 # /dev/mapper/Fedora-Swap swap  swapdefaults0 0
 RPHswapfile   swap  swapdefaults0 0

 so permitting me to reclaim that swap LV space

Re: FEDORA F20 boot HCPGIR453W CP entered; program interrupt loop

[Tom Huegel]

By it worked I meant the HCPGIR453W error went away and I was able to boot
the Linux Kernel.

 Based on your note some 45 min later, I have to ask: it worked means
 what worked?

 As Russ reports, kickstart installation (to EXT4 on top of LVM) works.
 Problem is that when one applies service, _and the kernel is updated_,
 reboot fails.
 In VM speak,  new IPL text is stamped on the minidisk, and it goes wrong.

 So ... you would do well to use _EXT4+LVM and then defer updating your
 kernel_ until the problem is fixed.
 OR ... if you can install so that _/boot has its own partition_ (or even
 its own disk), that would be safer still.

 --- snip ---

 Filesystems ... Think CMS EDF, the stuff you see when you eyeball your
 191 with DITTO. That's all there is to it. Different ideas, different
 requirements, and other factors have led to many filesystems being
 created over time. Linux supports more filesystem types than any other
 op sys. BTRFS and EXT4 are just two of them.

 BTRFS and ZFS do some of what LVM does, so people often dispense with
 LVM when using BTRFS or ZFS.

 The most common filesystem used in new Linux installations (I state w/o
 proof) is presently EXT4. Before that it was EXT3. At one point,
 ReiserFS had some traction. (long sordid story - not going there) Going
 back further, EXT2 was common on Linux before journalling was recognized
 as vital.

 LVM is the logical volume manager which can host any supported Linux
 filesystem. Think of it as an alternative to partitioning. (But most
 people still render individual disks as one large partition, even when
 it's not strictly required.) Feed disks or partitions into LVM as PVs
 and then mount filesystems on the other side of LVM as LVs. Some links
 which may help ... good bedtime reading ...

 and the plymouth (and maybe other) crashes are also results of the

Reproduced! I get dozens of these, similar, but different addresses
and instructions. I tried starting over and reinstalling, but to no
avail.
  
   when does it happen? after the installation? what application is it?
   looks as the getent tool, maybe run in a scriptlet during installation

  one more idea - the address looks as a wrap over kernel memory
  pages when there is no page allocated for 4A7A2ED000, but a page
  is there for 4A7A2EC000, where the target is being copied, it can
  be an over-optimized version of memcpy() or something like that
 
  I already debugged this kind of crash with older glibc in RHEL.
 Good point. Can this be reproduced with the command running in gdb?
 If so, what is in /proc/pid/maps at the memory location?

 cheers,
 Carsten

Re: Fedora 20

[Tom Huegel]

Just an update on this problem. It was my fault (no surprise there) I had
my install machine defined at 1G when I defined storage to 2G the install
worked as it should.

  I was trying to install FEDORA 20 on my z196 yesterday and it failed.
  I can't get back to the system until tomorrow or Friday to get more
  details, but I thought I'd ask if anyone else has had any problems.
 
  I had 2 failures One was when I tried to install with KDE I failed the
  software check missing requisites.

 ah, it could happen, KDE is not the primary desktop environment and we
 don't have the capacity to fix all problems during the development
 cycle. But you could be able to install a Minimal system first and then
 add KDE. The installer requires all dependencies for a group to be
 resolved at installation time.

  The other (I took GNOME this time) happened about an hour into the
  install when my CPU utilization went to 100% and I/Os went to zero...

 hm, more details would be needed here for a better answer, but
 installing GNOME should work. You can try XFCE too.


 Thanks

 Dan

  I know that is not much to go on but any insight would be helpful.
 
  Thanks
