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. I've been asked to make 2 linux LPARS into 4

File Space Utilization

2004-03-25 Thread Scully, William P
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 graceful

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. Eric Rossman Linux on 390 Port [EMAIL PROTECTED] wrote on 03/25/2004

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. Chris Cox [EMAIL PROTECTED] mm.com

Processor starvation

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

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. Rich Smrcina wrote: You indicate that you are adding paging volumes. What is VM's paging rate when

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? -Original Message- IABIAS : INTENSITY=90%; DURATION=2

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
