I used to work on Solaris and usually when I have to transfer the
content of a FS to another FS,
I'm using this :

ufsdump -f - /dev/rdsk/c0t0d0s0 | ( cd /newfs; ufsrestore rf -)


Now I'm working on AIX and
I have to copy File Systems on an AIX machine,so my question is
how can I do it ?
Any suggestions should be welcome.

man pax and/or man backup
both programs support files even bigger than 2GB.

But tar is not the best way to copy files I think.
For example there are problems tarring files bigger than 2G .
Isn't there another way of copying FS?

With the backup and restore command. You can do it exactly the same
way as you show above, just read the manpages for backup and restore
for the exact options.

One caveat though: when using JFS2 filesystems and restoring from
standard input, you might encounter a bug in restore. It'll hang,
and entering Ctrl-D will cause it to exit with an error. What happens:
"restore" reads the first few bytes of input (from stdin), determines
that this is a JFS2 filesystem, and then invokes either
/sbin/helpers/jfs2/restbyinode or /sbin/helpers/jfs2/restbyname. The
problem is that "restore" closes stdin before it invokes the helper,
so the helper blocks reading stdin (now connected to your terminal).
The workaround is simple: instead of invoking "restore" invoke the
appropriate helper directly.

man cplv

man backup ( close to ufsdump )

or do a copy with backup by file name and restore

# Striped example from the backup man page
$ cd /MyDir
$ find . -print | backup -ivqf - | ( cd Targetdir ; restore -xvqf - )

Replace the -x in restores parameter list with -T in case you would
like to see what would be copied

I have been using cpio with the -p option, and it works just fine.

Example:

cd /srcdir
cpio -pvdmu /destdir
(edit /etc/filesystems to point to new file system)
umount /srcdir
mount /srcdir (now using the new file system)

This cat can be skinned 100 ways.  This just happens to be my favorite,
because it is portable.

afaik AIX cpio does not support files bigger than 2GB also. Furthermore
it cannot handle sparse files. Thus it might not be your first choice
with AIX.

Not being spiteful, but using the -p option is "passthru"; just copying
files from one location to another, preserving ownership and
permissions.  I just copied a couple of 400GB filesystems about a month
ago with it (converting JFS to JFS2).  I wasn't backing up to tape or
file, just copying from one location to another.  I learned it on NCR,
and it works on Solaris, SCO (excuse the profanity), linux, the bsd's,
and AIX.  Yeah, I could have done it with each OS's special way, but
cpio has always done it for me in this situation, and I have never had
problems.

there is someting wrong with your cpio command
it doesn't work.
