I noticed that the %{_libdir} is set to /usr/lib (rather than

Am I right in that this is wrong ?
I was confused... the real thing is in the s390x-linux/macros file
underneath.
Hi,
sometime ago Mark appended to this forum the attached note (Sharing

I was not going to do the copies from a live system. I am going to mount
the target volume at /mnt and the source volume at some other point but I
think the tar method might be better.
As to the /usr and /var file systems being placed on to root.

On one of our servers we run the Ext3 file system and today a DF command
showed the root filesystem was 96% full. I ran some FIND commands
looking for files updated today and large. My goal was to find some
logs that I could maybe erase. What's interesting is that after a

William:
What filesystem are we talking about here? What kind of files?
One of the most common instances that is similar to what you describe is when an
open file is removed. If a file, say an application log file, is removed while
the application still has it open, the inode and it's status

It's quite possible that a large file was unlinked, but not closed, so
space was being held by it. After the reboot, that file would have been
closed, freeing the space.
I've seen this happen before, so it seems likely.

You might be able to track these down using lsof.
Don't know if this has already been suggested, but the du command can be
used to show the
hogs on the system. From within the /usr directory, I ran the following
command. This will show
directories where large files exist. In this case, my current directory,
represented by the '.' is
eating up
Fuser is a good command to run to check to see if a process has a lock on a
file. This could be scripted
to read in a filename, run fuser against, output results, next file, etc.

We're trying to work with Websphere and Oracle 9i as Linux guests (one
for each) on an MP 3000 H30 running z/VM 4.4 as a hypervisor.
Admittedly, this is a small box (1 GB of storage, and one CPU that's not
even running at full-power for an MP 3000), but we're seeing horrible
inconsistent response
What are your SRM settings?

Most disturbing have been a couple of episodes in which the Websphere
guest just simply stops responding to terminal inputs. Our terminal
sessions are via ssh, but these sessions seem to just hang. New
connections time out, and logged in
Nick,
We had the same episodes with un-responsive guests. These virtual
machines ended up on the E3 list. We've adjusted our LDUBUF and STORBUF as
show below. This allows users not to get stuck on E3. You can see if
users are on E3 by doing the indicate load command.

Paging rates are sometimes several hundred pages a second to both
e-store and disk. Ugly, but true, and adding the volume seemed to remove
a bottleneck that had kept us from maxing out the CPU.

Yes, but if you're not seeing anything in E3 then I guess those settings
aren't problematic (although they are set for a more CMS intensive
environment). Do you use QUICKDSP? What else is running? What does IND Q and
IND Q EXP report?

since we're running the CPU at 100%, we don't think the problem is all
page waits, although there have been some kernel messages from the
Websphere machine in particular that memory allocations for Java
processes (tasks?) are failing.
Check the max heap size for the JVM. If you're running

James,
Just keep in mind that when a system goes into heavy use, /var can get a lot
bigger pretty quickly, particularly if an application decides to do a lot of
logging. I recently had an Intel Linux system fill a 3GB /var for just that
reason.
Your /usr partition shouldn't grow at all, unless
Steve,
I'm kind of at a loss here. I don't really know what to suggest next.
Is there some reason you want to use a CTC connection, specifically? It
might be a whole lot easier to give the Linux system a connection to an OSA
card, or CLAW device, or a real HiperSocket to talk between the two
I'll work with the IBM support center on resolving it. Thanks Mark.
