How ot use

[A9515001]

First, I am very appreciate your guys' suggestiona and sorry for my poor English writing.

Now I found if I wnat to use shapshot, I must base on the ext3cow file system type. Is that right?

So if I want to create all file system based on ext3cow, How should I do ?

1. When install the Linux do not have ext3cow format type.

2. Just copy all the file to a new disk which formats by ext3cow.

I want to know you how to deal with.

Ext3cow is not a file system that comes as a deafult option in any
Linux distribution (that I'm aware of) so you're not going to be able
to install a fresh distribution onto an ext3cow partition right away.
Unless someone proposes a more clever trick, your proposed second
option of copying everything to a new ext3cow file system is probably
your best bet.

Good luck.

Gridnix will offer ext3cow as an experimental FS, it will be included in
the kernel but can't be selected as a primary file system (i.e. /
or /home) on installation.. since there is no fsck.

The best uses for ext3cow are compliant document storage or backing file
backed block devices for virtual machines that offer the same.

I will soon be releasing more tools for using ext3cow with xen,
utilizing xen's lower level (libxenctrl) library, I do not have an ETA
on these. They basically sync, pause, snapshot, unpause .. and repeat on
a schedule that you define in xenstore.
