Generating Core Dump

vinayan — Tue, 29 May 2007 07:27:39 GMT

When I exected the command
#fstyp /dev/vg00/lvol25

It terminated with a coredump

/dev/vg00/lvol25 is a addon swap

fstab entry follows
/dev/vg00/lvol25 ....swap pri=1 0 0

In swapinfo -t command it saying that 16% of that particular swap getting used.

Can anybody suggest what is wrong with the server ???

How many swap devices have you configured in the system? and can you post the output of the following here:

# swapinfo -mat

First of all, you are running fstyp on a LVOL that does not contain a filesystem. I suppose that it is possible that a swap area (especially if that swap area once housed a filesystem) contains enough data to get fstyp in a confused state (ie, it could read part of what was a superblock and then do more tests that would trigger a segmentation violation). I suppose the first thing to do would be to look for and install the latest fstyp cumulative patch. Since you didn't bother to identify your OS version, I have no idea what that patch might be.

What in the Wide World of Sports is vg00 doing with 25 (or more) LVOL's? That is a recipe for an extremely poorly organized system.
