hi,
i noticed something odd with venti and i am just trying to see if this
is an issue and if this needs to be addressed.
i think, by default, plan9 installation sets localhost as the address
for venti in plan9.ini. but at some point i wanted venti to announce
any (*) address. for some reason, i simply started venti/venti -a
'tcp!*!17034' to make it so. after this, i did vac from another
machine and it archived data. after sometime, i realized i may be
running venti on the same venti data area twice. when i did 'ps', it
looked like that. then i rebooted the machine and then tried
'dumpvacroots.new' command (from contrib). i noticed that venti arena
was corrupted. this is what i remember and if required i can try to
reproduce the issue.
the question i have is, is there any protection that prevents someone
from doing this accidentally? something like the last active venti
arena is marked 'IN_USE' so that if another instance of venti is
started (with read-write access), it can check for this? i agree user
has to be careful but given that venti archive is so critical, we
should avoid any accidental damage.
please pass your views.
thanks
dharani
