Subject: [9fans] new arenas from the same disk
Topicbox-Message-UUID: c98b2214-ead0-11e9-9d60-3106f5b1d025

i have a disk with two plan9 partitions (plan9 and plan9.1). the  
first one already hosts a 60 gig venti, fossil and all major  
necessities for a running plan9 system and is indeed working  
flawlessly. i would be very happy if anyone can point me towards any  
documentation on how to add the second plan9 partition to the running  
venti, increasing its size.

what i've done so far:

-create arenas.1 and isect.1 partitions on plan9.1;

-venti/fmtarenas arenas-two /dev/sdC0/arenas.1

-venti/fmtisect index-two /dev/sdC0/isect.1

what i'm thinking should be done next (according to my understanding  
of the man pages):

edit venti.conf and add isect-two and arenas-two thusly:

index main
isect /dev/sdC0/isect
isect /dev/sdC0/isect.1
arenas /dev/sdC0/arenas
arenas /dev/sdC0/arenas.1

- venti/fmtindex

reboot

from browsing the code it seems that fmtindex is for _new_ (therefore  
empty) arenas. is what i'm trying to do at all possible? what am i  
missing?
