Few questions about setting up and using a proper external log:
I have a system whose only drive is a raid 5 array. I assume putting hte
log on the array itself, on another partition, would be pretty useless,
if the data is on the array also. So, I could put in anohter drive, but
what are the usual redundency requirements for the external log? I
assume if it fails, the entire partition fails also.
So, one would need two raid setups to use this effectively? How much
data does the log usually use?
Thanks
