[9fans] Growing a venti

[Dave Eckhardt]

It seems as if the steps to add data arenas are:

1. Format them with fmtarenas
2. Append them to the arena list in venti.conf
3. fmtindex -a

And the steps for adding index sections are:

1. Format with fmtisect
2. Add them to the list in venti.conf
3. fmtindex
4. buildindex

I assume that fmtindex and buildindex need to
be run with venti shut down... how do people
usually do this?  Boot against some other
file server, such as a TIP9UG account?

What size should be given to buildindex -B?
More or less all of physical memory?

What you describe is what what I understand you should do.

When I rebuilt my index I booted from cdrom; The ISO on sources
can boot as an install CD or as a standalone live system.
I didn't use the -B option to buildindex though it may
have completed faster if I had.

[9fans] dosmnt

[arisawa]

Hello,

dosmnt does not work correctly.
because
term% echo /dev/sd*/dos*
/dev/sdC0/dos /dev/sdC0/dos /dev/sdD0/dos /dev/sdD0/dos

current codes are:

term% cat /bin/dosmnt
#!/bin/rc

rfork e
if(! ~ $#* 2){
         echo 'usage: dosmnt N mntpt' >[1=2]
         exit usage
}

x=(`{echo /dev/sd??/dos*})
if(test $#x -lt $1){
         echo 'not that many dos disks' >[1=2]
         exit usage
}

if(! test -f /srv/dos)
         dossrv >/dev/null </dev/null >[2]/dev/null

mount -c /srv/dos $2 $x($1)
term%


The fix is to replace last line
         mount -c /srv/dos $2 $x($1)
to
         g=$x(1)
         for(f in $x)
                 if(! ~ $f $g) g=($g $f)
         mount -c /srv/dos $2 $g($1)

the real fix is not to bind '#S' onto /dev twice.
but i changed dosmnt anyway.

I agree.
But why Kernel shows same things twice?
