Summary:Problem in ufsdump/ufsrestore and tar

Greetings,

Thanksn a lot for the replies. I did not test all the
options but i am attaching the response with
explanation which worked for me.

Problem
I am having problem in copying dir from one computer
to another.
Here is the error
UFSDUMP

ufsdump 0f - |rsh viper `(cd /export/home/sama;
ufsrestore xf -)`
Usage: ufsdump [0123456789fustdWwnDCcbavloS
[argument]] filesystem
Volume is not in dump format
tcgetattr: Invalid argument
ioctl I_PUSH ttcompat: No such device or address

TAR
tar cvfb - 20 /export/home/sama |rsh viper `(cd
/export/home/sama;tar xvfBbp -
20)`
tar: blocking factor must be specified with 'b' option
Usage: tar {txruc}[vfbFXhiBEelmopwnq[0-7]] [-k size]

a /export/home/sama/mkvol02.sh 1K
a /export/home/sama/mkvol02.out 1K
tcgetattr: Invalid argument

Please advice.

Solution


The "cv" can't work, you're feeding garbage into the
rsh, where
the tar x will see it.  Right?

Lose the block factors, they're not doing you any good
since
you're going over the net, not to a tape drive.

The tar c has is rooted (starts with "/"), don't do
this!

Backticks and parens on the rsh side again.

The tar x doesn't need B, that's on by default with "f
-".  Doesn't do
any harm, though.

Don't use the v option at all, you want to see if
there are errors.

You may have problems on viper's .cshrc; can you do a:

    % rsh viper echo ''
    %

...and get exactly *nothing* in reply (except a
newline and new 
prompt)?
That's what you want.

Try something like:

    % cd /export/home
    % tar cf - sama | rsh viper "cd /export/home; tar
xfp -"

Don't use the "p" option unless you're running as
root, it will get you
into trouble if you have any write-protected
directories.
