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!

NAME
native - native branded zone DESCRIPTION
The native brand uses the branded zones framework described in brands(5) to run zones installed with the same software as is installed in the global zone. The system software must always be in sync with the global zone when using a native brand. SUB-COMMANDS The following native brand-specific subcommand options are supported in zoneadm(1M). attach [-u] [-b patchid]... For native zones, zoneadm checks package and patch levels on the machine to which the zone is to be attached. If the packages/patches that the zone depends on from the global zone are different (have different revision numbers) from the dependent packages/patches on the source machine, zoneadm reports these conflicts and does not perform the attach. If the destination system has only newer dependent packages/patches (higher revision numbers) than those on the source system, you can use the -u option to update the attached zone to match the -revision packages and patches that exist on the new system. With -u, as in the default behavior, zoneadm does not perform an attach if outdated packages/patches are found on the target system. For native zones, one or more -b options can be used to specify a patch ID for a patch installed in the zone. These patches will be backed out before the zone is attached or, if -u was also specified, updated. install [-a archive] | [-d path] [-p] [-s] [-u] [-v] [-b patchid]... The native brand installer supports installing the zone from either the software already installed on the system or from an image of an installed system running the same release. This can be a full flash archive (see flash_archive(4)) or a cpio(1) or pax(1) "xustar" ar- chive. The cpio archive be compressed with gzip or bzip2. The image can also be a level 0 ufsdump(1M), a path to the top-level of a system's root tree, or a pre-existing zone path. With no options the zone is installed using same software as is running the global zone. To install the zone from a system image either the -a or -d is required. Either the -u or -p option is also required in this case. -a archive The path to a flash_archive(4), cpio(1), or pax(1) "xustar" archive, or a level0 ufsdump(1M), of an installed system. cpio archives may be compressed using gzip or bzip2. -b patchid One or more -b options can be used to specify a patch ID for a patch installed in the system image. These patches will be backed out during the installation process. -d path The path to the root directory of an installed system. If path is a hyphen (-), the zonepath is presumed to be already populated with the system image. -p Preserve the system configuration after installing the zone. -s Install silently. -u Run sys-unconfig(1M) on the zone after installing it. -v Verbose output from the install process.
