7.5.00.23: [bug in db_adddevice LOG] - Do additional data volumes need corresponding log volumes?

[v7.5.00.23 on 64-bit Linux]

I have 2 data and 2 (mirrored) log volumes (created at install time) and
then the autolog activated. I had to add 2 more data volumes on the fly to
deal with the temp space saturation problem while I was running a data
import but I cannot add their corresponding log volumes no matter what state
it is in due to the page size being converted incorrectly which yields a
-3017 error.

The 3rd & 4th data volumes have data so I cannot delete them, will having
only the 2 original 50MB mirrored log volumes with a 50MB autolog=on be ok
for a 4GB data volume array? (under heavy usage?)

Let me know if you want the utility log.

Thanks,

Kevin
