setting up crypto softraid
I have found myself replicating a tiny script that sets up crypto on most of my recent machines, either in rc.local directly or calling it from rc.local. Is this the right way to do it, or is there some support for it in rc(8) already that I missed? Jan #!/bin/sh RAIDPART=/dev/sd0o CRYPTOFS=/dev/sd1a MOUNTDIR=/crypto bioctl softraid0 | grep CRYPTO \ || bioctl -v -c C -l $RAIDPART softraid0\ && fsck $CRYPTOFS \ && mount -v -s -o rw,nodev,nosuid,noatime,softdep $CRYPTOFS $MOUNTDIR

Re: setting up crypto softraid
Or you can try this, also in /etc/rc. # Configure raid devices. until bioctl -c C -l /dev/sd0d softraid0; do done for dev in 0 1 2 3; do if [ -f /etc/raid$dev.conf ]; then raidctl -c /etc/raid$dev.conf raid$dev fi done On 07/29/10 22:04, Jiri B. wrote: > On Thu, 29 Jul 2010 13:38:18 +0200 > Jan Stary wrote: > > I use following, right after swapctl in /etc/rc, I'm happy with that ;) > > for try in 1 2 3 ; do > bioctl -c C -l /dev/sd0d softraid0 2>/dev/null ; rc=$? > if [ $rc -eq 0 ]; then > break > elif [ $try -eq 3 ]; then > halt -qp > else > : > fi > done

For example if you have a umass(4) connected when you boot things will get mixed up. Earlier today I thought about writing a script based on the hw.sensors.softraid0.drive0 sysctl value which will tell you whether it has been attached correctly and what device was attached.

What I was asking is whether there are variables I could set in rc.conf.local, as with other features. Probably not, so I will continue using my tiny scripts.

Without touching rc, I use this tiny bits in rc.securelevel:
for TRY in 1 2 3; do
bioctl -c C -l /dev/sd0m softraid0
if [ $? -eq 0 ]; then
DRIVE=$( expr "$(sysctl -n
hw.sensors.softraid0.drive0)" : 'online (\(sd[0-9]\)), OK' )
fsck -p /dev/${DRIVE}d \
&& mount -o softdep /dev/${DRIVE}d /home
break
fi
done
Ciao,
