finally I had time to look at my fs.
seems I'm lucky: the fake worm is ok.
I've replaced the cache disk and recovered; I encountered
'panic: fworm: rbounds 13219302' (my fs kernel is a bit old (2003))
but the fix mentioned here a while ago (fix conf.firstsb) worked.
since I wanted a backup (and if possible: mirror) 'right now' even
though my /sys/src/fs is out of date and does not yet have copydev,
and I don't want to pull a lot of changes from sources right now,
I tried copyworm
from: filsys main cw0f(w5w1)
to: filsys output f(w2)
this seems to have worked, but I have not yet accessed the result
(just switched off the machine while it looped after copyworm).
now my real question is:
would it be ok to use the copy f(w2) as mirror,
as in filsys main cw0{f(w5w1)f(w2)} ?
