Hi,
on a current i386 system I have almost all filesystems (incl. /) on a
RAIDframe (level 1). The RAID set is automatically configured.
I don't understand why the rc.d raidframeparity check is done so late:
$ rcorder -s nostart /usr/src/etc/rc.d/* | tail 
/usr/src/etc/rc.d/smmsp
/usr/src/etc/rc.d/raidframeparity
/usr/src/etc/rc.d/poffd
/usr/src/etc/rc.d/ndbootd
/usr/src/etc/rc.d/moused
/usr/src/etc/rc.d/mixerctl
/usr/src/etc/rc.d/inetd
/usr/src/etc/rc.d/identd
/usr/src/etc/rc.d/cron
/usr/src/etc/rc.d/Makefile
Shouldn't parity be checked (and possibly be rewritten) before filesystems
are checked and mounted?
I applied the attached patch which fixes what I think is wrong. It results
in raidframeparity executed earlier:
$ rcorder -s nostart /etc/rc.d/* | head 
/etc/rc.d/raidframeparity
/etc/rc.d/wdogctl
/etc/rc.d/raidframe
/etc/rc.d/cgd
/etc/rc.d/ccd
/etc/rc.d/swap1
/etc/rc.d/fixsb
/etc/rc.d/fsck
/etc/rc.d/root
/etc/rc.d/mountcritlocal
and in waiting for 'raidctl -P' to complete before continuting startup.
Any comments are welcome.
TIA, Jukka
