We haven't had time to try the new AAP, but it's on our TODO stack, and
this would be ane addon for that testing.

Re: Ansible Tower (AAP)

[Philip Tully]

Mark,

The Ansible tower is a UI and dashboard on top of multiple ansibles, it
also provides restful api's.
The current versions only run x86.
The challenge I have is RH has declined to port it to s390x because  "
nobody ever asks for it on s390x", luckily CITI has enough cloat to push
for a port.

Martin Schwidefsky

[PHILIP TULLY]

To all,

Today I learned that Martin Schwidefsky has died in a parachute 
accident.(see attached url for translated news story).


Martin was a deeply technical person, with Linux kernel expertise.  He 
presented at many technical conferences and was always willing to 
discuss and dig into the Linux puzzles.


I have worked on multiple technical issues with Martin, and while he 
could overwhelm my linux technical knowledge easily, he was always 
willing to help me learn.


Martin’s intelligence, wit and good nature will be missed.

Regards
Phil Tully

Re: Docker on Z

[PHILIP TULLY]

Paul,
The fall over works..  Our current test has 100 containers running in 
each of 5 nodes.  One node fails the other nodes now have 125 
containers.  This works but if we fail another node, the additional 42 
nodes might not fit on the remaining 3 nodes, so I could issue commands 
to grow the memory of these nodes, but i am not receiving any 
notification that the remains 3 nodes must grow to accommodate the 
additional workload

Docker on Z

[PHILIP TULLY]

We are looking to implement Docker on Z, as we have begun the testing
part of the issue is to be able to grow a docker engine and growing it
dynamically based on it's current needs especially when a node in the
Docker cluster fails.

So the question is does anyone see a way for the VM system to see the
memory resource grow, which would allow me to add more dynamically.

brtfs -u issue

[PHILIP TULLY]

According to the documentation to change the uuid of a btrfs filesystem 
in SLES 12 s390x, we should be using the  btrfstune with the  –u 
option, but this doesn't seem to work.   The result is we are unable to 
mount a duplicate copy of a disk with BTRFS in two different mounts on 
the same system.


Does anyone have any suggestions?

SLES12 migration finally

[PHILIP TULLY]

Hello All,

We are finally beginning to work on a SLES12 deployment for general use, 
this of course mean I (and more importantly my team) needs to get up to 
speed on systemd. 


The first item we would like to modify is our auto log on of root at the 
virtual console and iucv connectivity.  Currently we have the following 
configured:

For  iucv:
i1:2345:respawn:/usr/bin/iucvtty adpterm

For root at console:
1:2345:respawn:/bin/login -f root

Where is this configured with systemd?

TIA

Re: pid swap space used

[PHILIP TULLY]

Rob/Shane,

I appreciate your overnight assistance, I did modify the script to look
at all pids, with the same result.

I do realize that linux memory mgmt is lazy (delayed cache writes) and
that is why I was wondering if I can't find which current pid
has swap allocations, is there a way to run the swap chain to see what
process held it in the past.

From the looks of this system, I suspect an overnight backup process
utilizing the full memory allocation and populating swap.  That process
then finishes but swap doesn't' clear because of it's lazy attributes.

 Phil

No, by lazy in this context I meant that freed memory (pages) are not

If memory pressure ramps up sufficiently, kswapd will get kicked to

In addition to what Rob mentioned, there is de-dup and compressed
swap cache
out in the wild already. How does the mug end user figure out what's
what ?.


Hmm... when I add things up from smaps, my number is higher than what
free says. I see VMA's like

3fffd5d3000-3fffd5d7000 r--p 0017c000 5e:01 98592
  /lib64/libc-2.11.3.so

Rss:   8 kB
Pss:   6 kB
Shared_Clean:  4 kB
Shared_Dirty:  0 kB

Private_Dirty: 0 kB
Referenced:0 kB
Anonymous: 8 kB
AnonHugePages: 0 kB
Swap:  8 kB
KernelPageSize:4 kB
MMUPageSize:   4 kB
Locked:0 kB

With 22 processes having this mapped, I would count it as 22 times 8
kB while it really is just 8 kB on swap? And how come part of this is
private when it's read-only?

Re: pid swap space used

[PHILIP TULLY]

It appears my script was not good for a sles10 system as I was informed
by IBM tonight that Determining swap space used by a particular process
from smaps doesn't
appear to be available until SLES11 kernels


So I'm still looking for a way to see this but that isn't the way.

pid swap space used

[PHILIP TULLY]

I have a couple servers which show 100% swap space used but when I look
I can't find which pids are have pages in swap.

 free -m
   total   used   free sharedbuffers
cached
Mem: 12061  11410650  0152
6425
-/+ buffers/cache:   4832   7228
Swap: 1129   1128  1

I was using the following to show how much swap space was being used it
is either not working or there is nothing allocated to swap.

for pid in `ps -ef|grep  ora| awk '{print $2}'`; do echo -n Pid: $pid
; cat /proc/$pid/smaps |grep -i swap| awk '{SUM += $2} END {print SUM:
 SUM  kB ( SUM/1024  MB)}'; done


Does anyone have a different method for finding which pids are actually
using swap?

TIA

Migrating Linux on zFCP to new cpu

[Philip Tully]

Sue,

I just had the fun of moving 32 linux guests with allocated fcp luns.  When
it comes down to it this really depends on what is changing to your
connection to the san switch.  The SAN team will have to rezone the luns to
the wwpn's of the new cpu chpid (to the san team this is an HBA).  If you
are lucky and he new cpu connects to the same switches the linux side may
not need to change, but if the luns are connected through different wwpn's
on the switch side the  zfcp config must reflect this.

Phil Tully

vswitch name in sysfs

[PHILIP TULLY]

I was looking for a place within Linux that the vswitch name is stored
for each virtual nic.

I can query the nic information.
# vmcp q v nic
Adapter 0350.P00 Type: QDIO  Name: osatest Devices: 3
  MAC: 02-00-06-00-00-C5 VSWITCH: SYSTEM ESNET1

If you look at the data in this list, all of it is stored under
/sys/bus/ccwgroup/drivers/qeth
the only info I can't find is the vswitch name.

Does anyone know if it is stored with linux?

vswitch name in sysfs

[PHILIP TULLY]

 why would you want Linux to have that info?  You really don't want
to (IMO) build operational dependencies on VSWITCH names. 


With all due respect there are other places VM info is stored, I suggest
doing cat  /proc/sysinfo  as and example which
has LPAR and CEC level info stored.


I am not creating operational dependencies on this, I am merely looking
for stored info as a reporting method.

Suse after.local

[PHILIP TULLY]

We use the after.local file to run some initialization scripts.  When I
do a chkconfig, after.local shows up as off, yet it still runs.  Is
this correct behavior ?

The network_setup seems to obey the chkconig setting.
