RE: [uml-user] filesystem size

[James W M. <mcm...@ju...>]

The easiest method I have found for enlarging filesystems has been to
create a new sparse file to copy into
e.g. dd if=/dev/zero of=new_file bs=1k count=1 seek=$(( 1024 * 1024 )) ;
mke2fs new_file
would produce a file of 1G with a ext2 filesystem and then either I would
mount it and the original with -o loop and just cp -a or if I had a COW
file I would put it on a spare ubd device and do the copy inside the UML

I noticed that you appeared to be running e2fsck on a reiserfs
filesystem? I would surprised if this worked.

Also if cp -a gives problems using tar or cpio to pipe a archive over
also works
cd srcdir ; tar cf - . | (cd destdir; tar xpf -) as I recall, the man
pages list several versions to copy whole trees from one place to
another.

Most filesystems used with UML do not have partition tables but you can
now use them.
mounting becomes strange as a offset (usually 16384) needs to be
specified when using loopback devices to skip the partition table header
in the image file
