On another note, you seem to have doctored with the rootvg because it is quite unusual to have a 1GB PP-size. Usual PP-sizes in rootvgs are indeed 64MB and 128MB. I don't know what exactly you did, but: might it be that this has something to do with it?

I hope this helps.

I figured out the problem. Yes I had already used sysdumpdev to verify that I was actually using the devices in question. The rootvg is fine, the reason it has a 1GB PP size is because the disks it was installed on are 4TB disks. So I believe it defaulted to 1GB PP size.

The problem was with the dumpcheck script. I ran it with debug on and found that it was reporting the block size for the dump device as 512 bytes. When I knew in fact that the block size was 4k. I found that it was an old version from 2010 that was missing a lot that the version on on most of our other servers were using. I copied the later version of the script, which correctly specified the block size of the dump device, and voila. So really, the dump device was fine, just the dumpcheck script was reporting the wrong size.

Thanks for your reply!

yum-debug-dump

yum-debug-dump(1)														 yum-debug-dump(1)

NAME

       yum-debug-dump - write system RPM configuration to a debug-dump file

SYNOPSIS

       yum-debug-dump

DESCRIPTION

       yum-debug-dump is a program which creates a gzipped file containing a lot of information useful to developers trying to debug a problem.

       By default it will output a file to the current working directory named yum_debug_dump-<hostname>-<time>.txt.gz. This file contains no pri-
       vate information but does contain a complete list of all packages you have installed, all packages available in any  repository,  important
       configuration and system information.  You can view this file using the 'zless' command.

       You can use the coresponding program yum-debug-restore to act on this file and restore a set of packages (much like dump/restore).

FILES

       As  yum-debug-dump  uses YUM libraries for retrieving all the information, it relies on YUM configuration for its default values like which
       repositories to use. Consult YUM documentation for details:

       /etc/yum.conf
       /etc/yum/repos.d/
       /var/cache/yum/

SEE ALSO

       yum-debug-restore (1)
       yum.conf (5)
       http://yum.baseurl.org/

AUTHORS

       See the Authors file included with this program.

BUGS

       There are of course no bugs, but should you find any, you should first consult the FAQ section on  http://yum.baseurl.org/wiki/Faq  and	if
       unsuccessful  in  finding a resolution contact the mailing list: yum-devel@lists.baseurl.org.  To file a bug use http://bugzilla.redhat.com
       for Fedora/RHEL/Centos related bugs and http://yum.baseurl.org/report for all other bugs.
