Ext3 users - Nov 2004 - Externalize journal

Hello

Is it possible to externalize the journal of an already existing 
(journal inside) ext3 FS ?

Here's what I did to create a new FS with external journal for 
/dev/emcpowerl2 on /dev/emcpowerl2
mke2fs -O journal_dev /dev/sda10
mke2fs -J device=/dev/sda10 /dev/emcpowerl2
it works perfectly , but can I do the same whitout reformating the 
original FS;  /dev/emcpowerl1 which is in production for exemple

thanks.

Use "tune2fs -O ^has_journal" on unmounted filesystem to remove the
existing journal.  Then "tune2fs -O has_journal -J device=/dev/sda10"
to add the journal to the new device (unmounted also of course).
