EXT3 on raid with external journal...

Tue Apr 13 11:05:08 UTC 2004

I have a raid5 array on my web server for which I am currently 
considering a move to ext3.  I want to use an external journal to 
improve performance.

Since the external journal would reside on a drive  that is not 
participating in the raid array, I'm wondering what the behavior of an 
ext3 filesystem is should the device an external journal is on should 
fail.  If it reverts to ext2 behavior upon failure, then I can justify 
using a non-raid device for an external journal.
