Subject: My pseudo worm is getting crouded ...

Hi,

My main file system resides on a cached pseudo worm device which 
currently has a 1GB disk for the worm part.  I suspect it may be 
getting full.

I'd like (very much) to add a new disk to the SCSI chain, go
into config mode, redefine `filesys main' and be merry.

Can this be done?  Did anyone do it and survive?

My source browsing brought me to the (maybe wrong) conclusion that
redefining the filesys in config mode seems to be feasible.
config() will add the drive to the list of `main' and devinit()
it, which will write an empty bitmap at the end of the drive.

The question is: will the fake worm gracefully overflow into the
newly added drive?

Any hints will be mightily appreciated!  Loosing my `main' ain't
a happy prospect.

thanks

blumzi
