Hi, I have an ext3 file system on top of LVM and i use journaled mode. I would like to make a snapshot of my filesystem while the application is running in order to backup on another physical storage. For that i have to create an LVM snapshot and then to mount it in read-only for copying the content. This is not possible as far as ext3 needs to do a log replay at mount time ( AFAIK). I would like to know how do that : when is the VFS lock patch needed ? what does it change in the VFS behavior ? and what is the effect on my application ( on the journal usage and the performances for instance) ? The next question will be to know whether an ext3 snapshot feature is planed or if i need to use EVMS rather than LVM.
