2.2. Use of journaling file systems on loop device
Don't use a journaling file system on top of file backed loop device. Device
backed loop device can be used with journaling file systems as device backed
loops guarantee that writes reach disk platters in order required by
journaling file system (write caching must be disabled on the disk drive, of
course). With file backed loop devices, correct write ordering may extend
only to page cache (which resides in RAM) of underlying file system. VM can
write such pages to disk in any order it wishes, and thus break write order
expectation of journaling file system.
im going to use loop-aes from loop-aes.sourceforge.net to make an encrypted filesystem image.
am i right, in thinking that the about, is telling me that after i have setup the encrypted loop (pointing to /home/user/filesystemimage)
i should format it as a NON journalling file system (like ext2)
im sure last time i did this i used ext3 !
or maybe its saying dont make a jourrnaling file ssytem withing the encrypted file system ?
