Solaris 10 - ufsdump hangs

Anyone ever see an issue where ufsdump 'hangs' after the IV Pass?
Normally, it will update with an estimate of how long it will take to complete...and update the info every 20 minutes.

I'm running the following command:

root# ufsdump 0f - /fsmount | ( cd /zfs/newfsmount ) ; ufsrestore rf - )

(we are moving from UFS to ZFS - on Solaris 10!)

I've got 2 UFS file systems that just won't work with ufsdump. I've run fsck with no issues found, ran the ufsdump while mounted (apps and database down), ran it while it was mounted read-only (with apps and database down), ran it while file system was unmounted (with apps and database down). Nothing works.

Yet I'm using ufsdump on more than 10 other UFS file systems with no issue.

No error messages from ufsdump, nothing in messages file...

DUMP: Date of this level 0 dump: Sat Sept 27 14:16:16 2014
DUMP: Date of last level 0 dump: the epoch
DUMP: Dumping /dev/rdsk/c14t600015D000236B00000340200111052Cd0s2 (server004:/fsmount) to standard output.
DUMP: Mapping (Pass I) [regular files]
DUMP: Mapping (Pass II) [directories]
DUMP: Writing 32 Kilobyte records
DUMP: Estimated 441443448 blocks (215548.56 MB).
DUMP: Dumping (Pass III) [directories]
DUMP: Dumping (Pass IV) [regular files]
(this is where it should update with how long it will take...but I get nothing...left it running for 12 hours and still nothing)

If I control-C the dump, it ask if I want to abort...last night was the first time I said no. It finally started showing/updating the status...
DUMP: 0.12% done, finished in 19962:24

It continued showing updates until completed - but it never copied one file! It did create some of the directories on the new disk (13 of the 99 top directories)
and a total of 382 directories, but NO data, ascii, text, non-directory files.

Solaris 10 1/3 - generic 147147-26

One of them I finally ran tar against to get the copy completed - with no issues.
The last one I'll have to do the same but it will take a whole weekend to complete. FS is only 504G (where I've had 2TB FS convert with ufsdump with no issues). Plenty of free space, plenty of free memory, no issues with inodes on old UFS FS, new ZFS pool has enough space....

Hopefully someone has seen this before and knows what it is...thanks!

LEARN ABOUT OSX

lwp-dump5.16

LWP-DUMP(1)						User Contributed Perl Documentation					       LWP-DUMP(1)

NAME

       lwp-dump - See what headers and content is returned for a URL

SYNOPSIS

       lwp-dump [ options ] URL

DESCRIPTION

       The lwp-dump program will get the resource indentified by the URL and then dump the response object to STDOUT.  This will display the
       headers returned and the initial part of the content, escaped so that it's safe to display even binary content.	The escapes syntax used is
       the same as for Perl's double quoted strings.  If there is no content the string "(no content)" is shown in its place.

       The following options are recognized:

       --agent str
	   Override the user agent string passed to the server.

       --keep-client-headers
	   LWP internally generate various "Client-*" headers that are stripped by lwp-dump in order to show the headers exactly as the server
	   provided them.  This option will suppress this.

       --max-length n
	   How much of the content to show.  The default is 512.  Set this to 0 for unlimited.

	   If the content is longer then the string is chopped at the limit and the string "...
(### more bytes not shown)" appended.

       --method str
	   Use the given method for the request instead of the default "GET".

       --parse-head
	   By default lwp-dump will not try to initialize headers by looking at the head section of HTML documents.  This option enables this.
	   This corresponds to "parse_head" in LWP::UserAgent.

       --request
	   Also dump the request sent.
