Alex Osokin:
|Finally I got such solution:
|Do disklabel and newfs on your new drive (you may type /stand/sysinstall
|as root then follow your intuition :))
|Then mount your / on new drive to /mnt for example and do
|
|tar cf - /etc | tar xvpf - -C /mnt
|tar cf - /.... | tar xvpf - -C /mnt
Aaron Jeremias Luz:
|Or you could just use
| tar -C / -cf - . | tar -C /mnt --exclude mnt/\* -xvpf -
|after you've mounted all your filesystems at the correct
A bit late jumping in on this thread, but I went through the same thing
this weekend myself :-)
A follow-up question. Is there a version of tar or cpio that stores
FreeBSD's extended file attributes (chflags(1)) and longer i-node numbers.
Seems like sometimes when I've used them in the past to copy root or data
UFS partitions I get some complaint (truncating inode number, etc.). E.g.:
cd $dir1; tar cvf - . | (cd $dir2; tar xpf -) OR
cd $dir1; find . -print | cpio -dumpv $dir2
On that thread, is dump(8) safe to use when copying files between file
systems if your target FS has a different geometry from your source FS?
For example, using:
cd $dir1; dump 0f - / | (cd $dir2; restore xf -)
I expect that handles FreeBSD extended attributes, so if there are no other
obstacles, maybe that's the way to go.
I ended up making my new root exactly the same size as my previous, and
used dump/restore to copy it over. I then used tar/tar to copy my other
data partitions (since there are no files with FreeBSD extended attribute
settings on those FSs AFAIK).
