Question about fsck when rebooting

I've got a Solaris 9 (Intel) box that doesn't have a monitor or
keyboard hooked up to it. Sometimes it gets power cycled by accident
(well stupidity on my part). However, when this happens it can't
recover unless I hook up a keyboard and monitor and manually run
fsck.

Is there some way to get it to just do it without me having to go
through that?

Thanks

Joe

Enable logging on your UFS filesystems.

man mount_ufs

# find / -name mount_ufs -print
#

Man pages aren't named that way. You'd need to either do
-name "mount_ufs*" or
grep mount_ufs /var/sadm/install/contents

/usr/share/man/sman1m/mount_ufs.1m

Part of package SUNWman, which is found on Software CD 2/2.

Well, as I said above, "although the man page is there"...

I gave the find command as an example that I couldn't find the command
on my machine, not the man page.

The find command line I posted isn't looking for a man page (as I
said, I found that), I'm looking for the mount_ufs command itself.

Thanks

there is no mount_ufs command (the man page is there to differentiate
between different modes of operation of the command for different filesystem
types). The command that you would use would be something like (the special
device name is probably different on x86 based machines);

# mount -F ufs -o logging /dev/dsk/c0t0d0s6 /export/home

Having said that you are best served specifiying this in the /etc/vfstab
file to ensure that the filesystems are logging on a reboot.

If you read the synopsis section carefully, you'll see the command is
named mount, and if it's not there, your system won't boot.

THere's no command called "mount_ufs"; it's just a manual page; the
command is /usr/lib/fs.d/ufs/mount.


Just add "logging" to the options field in /etc/vfstab.

Sorry. I interpreted your query as "I could read the man page, but I
couldn't find the man page in the filesystem".

There are many man pages that do not have the same name as any program
or file in in the filesystem. Often like mount, there is a separate man
page for special subsets of the command.

mount_*
fsck_*
share_*

None of the above items exist as an independent command, all are
explanations of subsets of the shorter command.

In each case the SYNOPSIS section of the man page should detail the
needed command (including path if it is uncommon).

(Plus there's the man page for 'boot'... good luck finding that one)

FWIW yes they do, in most cases (though you're right if you're saying
that those are not their exact names). The UFS-specific mount command,
(manpage mount_ufs) for example, is /usr/lib/fs/ufs/mount while the
UDFS-specific labelit command (manpage labelit_udfs) lives in
/usr/lib/fs/udfs/labelit and so on.

This probably comes under the heading of Completely Useless Information :-)

Sorry for the confusion, and thanks to all. I think I've got it
working now.
