Yes, I understand. I was thinking more of an offline utility for doing

So I guess it doesn't really work. This is why I ask the experts. I'll
keep experimenting because due to the requirements of needing to
physically move disks around, being able to move the log back and

from internal to external would be extremely helpful.
Thanks!
Just out of curiosity, what is your use case? Why do you need/want to
move logs around?
Every so often I rotate certain drives from production servers to
semi-offline servers for testing and verification. The production
servers have SSD for cache and the fast external journal but the testing
servers do not. The testing servers need to be able to test and verify
the filesystem and do periodic synchronization/mirroring but obliviously
can't use the original filesystem without the journal. Also some of
these drives are moved offsite so being able to put the journal back to
its internal position would simplify things.
Of course it would be possible to have extra drives in the testing
environment that the logs could be moved to but the testing servers are
very physically limited as to what can be hooked up to them so there
really isn't enough room or ports for those extra drives. Plus the whole
offsite thing.
It's more of a "want to help make life easier" than a hard requirement.
