Subject: JFS i-nodes summary
Keywords: jfs i-nodes filsystem
Date: 28 Aug 92 17:46:56 GMT
Organization: Utah Supercomputing Institute

Several people have asked me to summarize the information I received
concerning allocation of i-nodes in a journaled filesystem.
Unfortunately, I've received only one response and it basically a
re-phrasing of my post...  So it looks like there are plenty of folks
with questions but few with answers.

There has been another post here recently concerning where one might find
papers or informal documents on the jfs internals, and I too would be
interested in finding these, if they indeed exist for public consumption.

What I have determined heuristically (pure experience and
experimentation): 

	(1) i-nodes in a jfs are statically allocated.  I had hoped that
	even thought the i-nodes were preallocated, if you started
	exceeding dataspace and had plenty of i-nodes, the system would
	diminish i-nodes to compenstate...)  This was verified by using
	one of my 2 gig filesystems --- I calculated the size of the data
	blocks available by:

		X = Space available reported by df
		Y = Space in use reported by 'du -sk /fs'
		Z = Size of filesystem (2Gig) in K.

		Theoretical_File_Limit = Z - ( X + Y ) ;
		Test_File_Limit = Z - X ;

	Using a C program and dd I could create a file of
	Test_File_Limit.  I could not make it any larger, showing that
	I-nodes were not de-allocated dynamically and supporting the idea
	that they must then be allocated statically.

	(2) Given that i-nodes are 128 bytes, it became obvious from
	'doing the arithmetic' that AIX pre-allocates ONE I-NODE FOR
	EVERY 4K BLOCK.  In our situation, that means that roughly 65
	Megabytes of a 2Gig filesystem are used up in i-nodes.  We figure
	that, given our situation and needs, that is a waste of 55 to 60
	meg per 2 gig filesystem.  Since we have 8 of them, that means we
	are losing 440 Megabytes to 480 Megabytes of scratch file space
	for our applications... Ouch.


Can any Austin IBM'ers or others verify or refute these claims?  Is there
an alternative method for getting more out our filesystems?  Is there
away around static pre-allocation of i-nodes?

Before the flames fly, let me say that I am not complaining (really).  I
just want an accurate picture of the problem and anyone's input on
possible solutions.  We have a very specific need for large filesystems
with few files -- hardly a generic situation.  Most will find the 'i-node
per 4k block' acceptable (I assume) in the general case.

Looking forward to any feedback,

Subject: Motif oddity when using non-IBM xterminals
Date: 1 Sep 92 22:00:23 GMT
Organization: University of Texas at San Antonio

This question has been previously posted to comp.windows.x.motif and
received little feedback.  It seems to be RS/6000 specific, so I will
try this newsgroup.

We have an RS/6000 (AIX 3.2, X11R4, Motif 1.1) which is used with several
other workstations including Suns, and PCs running SCO.  We do a lot of
X/Motif development on the RS/6000, and I have come across this annoying
problem.  For any program which we compile on the RS/6000, the XmText and
XmTextField widgets do not display in the proper font if a display other
than the RS/6000 console or the IBM XStations is used.  The widgets just
come up in the default fixed font.  The fonts are definetly resident on
the other servers, they are even used by the same program for different
widgets.  If I compile the offending programs (any Motif program using a 
text widget) on the Sun or the PC, the problem goes away.  For this reason
I claim that it is RS/6000 specific.

If anybody has had similar experiences, I would like to hear from you.

Thanks for the response. We'll get the fix for 3.2, and see if that
helps. I find it rather disconcerting that 3.2 was shipped with such
major bugs: i.e. software that just plain doesn't work. Was it even
tested before being shipped?

Regarding tokens, It seems the O'Reilly & Associates, Inc book
"Managing NFS and NIS" (April, 1992) disagrees with AIX regarding
tokens. For example:


Token for		AIX		from O'Reilly & Assoc
				
passwd			+::0:0::	+:*:0:0:::
group			+:		+:*:*
aliases			<none>		+


So, which format is the "standard" NIS format? Is it relatively
vendorindependent, is Hal Stern (author of Managing NFS and NIS)
wrong and/or confused, or has AIX broken from the "standard"??

Thanks for your help,

Subject: IBM Color Monitor flakiness
Keywords: color monitor hardware high voltage intermittent
Organization: Worcester Polytechnic Institute, Worcester, MA
Date: Wed, 2 Sep 1992 18:43:40 GMT

Hello,

I'm having an intermittent problem with our color monitor.  It's an
IBM 6091 19, and it's hooked up to an RS6000.

It does two rather unsettling things.  Here are the symptoms:

1) Monitor momentarily brightens.  It's as if someone were pressing
that black button on the control panel for a half second to a second.
This wierd spell occurs for about 1/2 a minute, then everything goes
back to normal.

2) I hear a snap, and notice that one or two adjacent scan lines turn
black.  It seems to last for only the length of time it takes to scan
one or two lines, in other words, it happens so fast that I can't
really characterize it any better.  It has occurred 2-3 times in one
day, but usually only 1-2 times a week.  (ONLY?  It shouldn't happen
at all!)

Problem 1 is annoying because sometimes I can't tell if there's
something wrong with my eyes or not.  However, since I'm still under
warranty, I'd rather not wait until something actually burns out to
figure out what the problem was.

Problem 2 is more of a worry.  It seems to be a high-voltage problem.
IBM service guys just a week ago replaced the Low Voltage supply and
the Arc Suppression board.  They were pretty confident it was now
fixed.  I've noticed that it occurred once in the past six days since
they replaced things.

The service guys were pretty much at a loss as to what was wrong with
the monitor.  They were pretty good at reading the manual and
replacing boards, but claimed that the fluorescent lights might have
something to do with the intermittent intensity problem.

So, does anyone have any tale to relate that might help isolate the
problem?  If your suggestion works, you can send IBM a bill for your
services. ;-)  But seriously, I could use some suggestions.

Thanks a heap,

I'm rather fond of the -M option, but I don't use it the way you do.  I simply
have an "include x.u" in my Makefile (I "touch" x.u when I add the include),
and haven't had problems actually compiling. The -E option does produce stdout,
but, as you noticed, -M doesn't.

What level of AIX are you running?  3.1?  3.2?  I believe
you will be interested in picking up the fix for APAR ix24854.
For future reference, people with problems/questions should call
1-800-237-5511 instead of hoping that someone on the net has
the time or knowledge to answer serious questions like this.
Please don't take this statement as chiding.  But we care about the
quality of AIX and think the 1-800 number is the fastest way
to a problem resolution, rather than groping for answers on the
net.  Anyway, to order the fix, you gotta call the 1-800 number 
anyway.......

   if you want this to be handled, but not interpreted (displayed),
   use xdvi (from export.lcs.mit.edu);

   if you want PS graphics to be interpreted as well, you need a
   PostScript interpreter (you will then be previewing .ps files,
   however, and not .dvi files and the previewing task is not
   specifically related to TeX anymore);
   ghostview/ghostscript (from prep.ai.mit.edu) is reaonably good

Actually, I'm in the process of modifying a boot diskette so that I can
reinstall over the net using backups (full and incremental) made with
GNU tar.  This is not trivial.  Hence, I'm also trying to insure that I
don't have to do this again till at least 3.3, by having it make the
BLV from the restored kernel.

It would be very preferable, as you indicate, to be able to boot a
minimal system from which I can do whatever I please.  This became most
clear to me when the 3.2 installation completely failed on my machine
and I had to do it by hand.  (The even sadder part is that the bug
which caused it to fail will probably never be fixed, and it will
happen again next time, and I still won't have a "mini-root".  SIGH.
At least I know the ins and outs of the LVM now.)

I have never heard of this requirement before - and Ive heard many
about AIX deficiencies from customers and support personnel.
(at least more than I can count using my fingers and toes :-))

11 systems programmers independently changing the rootvg of 27 RS6000's
sounds like quite a unique environment to me. At first glance, the first
solution that comes to mind is to change volume group arrangements so
that rootvg is more static. IE rootvg should just have AIX stuff in it.
Or is this how it is already?  And I dont see how inode backups solves
your problem.

Bottom line is that I dont think the IBM designers are concerned about
this because it seems to be the first time that it has come up.

If any IBM'ers think I'm wrong , please correct me via email to save me
much public embarrasment.

If any customers think I'm wrong, please feel free to correct me here on

Anyone know the RS/6000 equivalent of syscall() (2)?

The real question:

We're trying to port the CMU cthreads library, which relies on being able to  
locally redefine the select() function.

Under SunOS, it's a breeze. Write the new select() func which calls the kernel  
select routine via syscall() - then link it early in your build.

Under AIX, we're lost.

Help appreciated.

Fellow AIXers,

	The directory /etc/vg contains a file vg<VGID> for each
of the VG in the system. What is this file for? Does'nt all the VG related
info reside in the ODM?

	Also if you exportvg a VG, the info for that VG gets removed
from the system, but the /etc/vg/vg<VGID> file fir that VG get left
behind. Is there a problem if this file is physically removed?

	Will there be a problem in a subsequent import of the VG?

	I would appreciate any responses to the above questions.

Thanx,

I need help in setting up a connection between AS/400 and RS6000/AIX on SNA.
are there any public domain software that let you do it ? what about 
commercial software ? what are the problems you faced in doing the
connection ? I haven't SNA programming , although I have done socket 
programming and understand TCP/IP.  Any help is greatly appreciated.
Thanks in advance.
