Thanks. I'll try to upgrade to b105. That'll only happen probably in a few
months time.
The zfs files contains Oracle and oracle tablespace files.
When I did the send command Oracle was shutdown.
I just did a receive as well recently and the 20gig file only took about 15

Thanks for the response. Being a laptop I don't have other pools to choose from
- just the rpool:)

I've been searching without success if this has been done or even discussed

Would it be possible now or in the future to use an SD Card on a laptop as a
cache for ZFS?
I've been trying to do this with OpenSolaris 1108 on a Dell XPS M1530 laptop.

I've been told we got a BugID:
"3-way deadlock happens in ufs filesystem on zvol when writing ufs log"
but I can not view the BugID yet (presumably due to my accounts weak

Perhaps it isn't something we do wrong, that would be a nice change.

Given this is a key area of interest for zfs at the moment, seems like it
would be a useful resource.

Niels,
I do this all the time, to a USB connected external drive. And I have

I don't see why you could mount an NFS mount from the service where you
want to backup too. I wonder if windows does something bad to the file,
is it larger then 2 Gb?
