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!

quotarestore

QUOTARESTORE(8) 					    BSD System Manager's Manual 					   QUOTARESTORE(8)

NAME

     quotarestore -- restore dumped quota information to a file system volume

SYNOPSIS

     quotarestore [-d] file-system [dump-file]

DESCRIPTION

     The quotarestore program restores dumped quota information to a file system.  The file dump-file should be in the format produced with
     quotadump(8).  The quotas, expiration times, and configured grace times listed in the dump file are loaded into the named file system.  The
     file-system argument should be a file or directory on the (mounted) file system, not a device special file.

     If the -d option is given, quota entries on the file system that are not mentioned in the dump file will be deleted.  Otherwise, they are
     left alone.

     If the dump-file is not specified, standard input is used.

SEE ALSO

     quota(1), libquota(3), fstab(5), edquota(8), quotadump(8)

HISTORY

     The quotarestore command appeared in NetBSD 6.0.
