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!!
