Ext3 users - Mar 2004 - Journal file location

Hi,

Is there any way that one can change the location of the journal
file when the file system is created ? For eg., instead of using inode# 7
and the blocks at the beginning of the file system, I'd like to use an
inode at a different cylinder group and some other set of blocks. Even if
I'm allowed only to use one of the reserved inodes, is it possible to put
the journal file somewhere in the "middle" of the file system rather
than
at the beginning ?

Thanks,
Vijayan

You can use any blocks in the filesystem, assuming you can set up a file as
you want it.  For example, if you allocate inodes until you get one in a
block group of your choice, then create a large enough file there and rename
it to "/.journal" in the root of that filesystem, umount, delete the
old
journal, and then run e2fsck on the filesystem.
