[gentoo-user] root (/) read-only?

[gentoo-user] root (/) read-only?

Hey guys,

Quite often if I leave my computer on for a few hours, I come back and try
to do something and I find that my system has all of a sudden changed from
rw to ro on my root partition... Has anyone else experienced this? One thing
I noticed is that I get an error message upon sstartup about not being able
to find fsck.xfs upon startup for /dev/hda4 (my root partition). could this
have anything to do with it? I am running into a lot of problems beacuse of
this since a lot of programs rely on writing tmp files to /tmp on my root
partition. A lot of programs freeze or crap out and I have to do a hard
reboot, which I know will cause a problem one of these days....

Thanks in advance!

Dave

Check your filesystem. Linux will remount filesystems ro if it finds any 
errors.

Install it, asap. But before, boot into a LiveCD and fsck.xfs /dev/hda4 from 
there.

Make /tmp a seperate filesystem (if you have enough ram, you could use 
tmpfs).

HTH...

It wouldn't do much

[nelz@hactar iso]$ whatis fsck.xfs
fsck.xfs [fsck]      (8)  - do nothing, successfully

You need to use xfscheck for this. emerge xfsprogs and check out your
filesystem.

[gentoo-user] Named problem, I'm beyond my depth and need a little help here

[Bob Young]

Installed 2.6.11-hardnend-r15 to use as a secondary DNS server for the
four domains I have. I can get named to start but it's by brute force,
and I want to understand/fix the problem with it not starting via the
default init script.

Here is what the start{} section of /etc/init.d/named looked like
originally:

start() {
        ebegin "Starting ${CHROOT:+chrooted }named"
        checkconfig || return 1
        start-stop-daemon --start --quiet --pidfile ${PIDFILE} --exec
/usr/sbin/named -u named -n ${CPU} ${OPTIONS} ${CHROOT:+-t $CHROOT}
        eend $?
}


With that init script, here is the result I get:

ns BYoung # /etc/init.d/named start
 * Starting named ...
usage: named [-c conffile] [-d debuglevel] [-f|-g] [-n number_of_cpus]
             [-p port] [-s] [-t chrootdir] [-u username]
named: extra command line arguments                [ !! ]
ns BYoung #


*******************************************************************


If I change the start{} section of /etc/init.d/named to this:

start() {
        ebegin "Starting ${CHROOT:+chrooted }named"
        checkconfig || return 1
        /usr/sbin/named -u named -n 1
        eend $?
}


Then I get this result:

ns BYoung # /etc/init.d/named start
 * Re-caching dependency info (mtimes differ)...
 * Starting named ...                            [ ok ]
ns BYoung #



1. Why does the original version of the init script not work?

2. What I can change so that it will work?

Please don't hesitate to ask for further information if there is
something I've left out that would be relevant or helpful.

Thanks for any Help
Bob Young

Try setting "set -x" somewhere at the start of the init script and look
at the verbose output.

I figure it's something to do with ${OPTIONS} ${CHROOT:+-t $CHROOT}
which I presume would be in /etc/conf.d/named(?)

[glumtail]

This happens offen in my system.

My root filesystem is reiserfs and /home is ext3, when i extract tar
packages it says it is a readonly filesystem.

Fix your /etc/fstab - it thinks your root partition is xfs, when it
isn't. You either: a) didn't change it during installation; or b)
overwrote it in a recent update.

Since his root filesystem is read-only, he needs a bit more help I guess 
because he can't simply use his favourite editor to edit fstab. Well, he can 
but he can't write the changes to his harddisk. ;-)

You boot from a live cd (any actually). If it is a gentoo live cd you mount 
your root partition under /mnt/gentoo. If it is some other cd you have to 
find out where to mount. Now you cd to /mnt/gentoo/etc and edit fstab. Write 
it back and reboot the box without cd.

Or from the running read-only system:

# mount -t reiserfs -o remount,rw /dev/xdx# /

The type and/or block device may not even be necessary.
