To see how easy it is to move from one to the other: this creates an ext3 from ext2: tune2fs -j <device> and this the other way round: tune2fs -O ^has_journal <device>; e2fsck <device>
While you could move from ext2 to ext3 with a running writeable mounted partition without any problems, the other way round is more problematic and should only be done with unmounted partitions. regards On Tue, Sep 9, 2008 at 4:32 AM, Edgar D' Souza <[EMAIL PROTECTED]>wrote: > On Mon, Sep 8, 2008 at 6:08 PM, Bernhard Schauer > <[EMAIL PROTECTED]> wrote: > > Hi Ed, > > > > as ext2 is a subset of ext3 it is also mountable as ext2 (but then > without > > journalling).
