ext3 + external journal -- Howto..




I am new to ext3 + external journal.  Is there any howto I can look at?


this is what I understand
1. mke2fs -O journal_dev /dev/md5
2. mke2fs -J device=/dev/md5 /dev/md0
3. mount /dev/md0 / -t ext3   ( hmm.. what do I need to put on fstab?? )

/dev/md5 is a two drive RAID 1 partition
/dev/md0 is a 4 drive RAID 5 partition.

questions:
1. I am running RedHat 9.0.  what extra software I need to use?  do I need to patch the kernel and recompile it?
2. what do I need to do on fstab when I use ext3 + external journal.
3. do I need to run "tune2fs -i 0 -c 0 /dev/hdb1 ?
4. do I need to modify LILO bootloader?


thanks!!
