problems with openrc

[saturnus]

Hi,

I keep getting the following messages at boot-up:

error: fopen (/var/log/messages) failed read-only filesystem

warning: temporary log file left behind /lib/rc/init.d/rc.log

What does it mean and how do I solve the problem

Regards,

Saturnus

looks like your /var/log directory is on a partition that is mounted read only .. check your fstab settings .. or you have incorrect directory permissions .. change them to allow root to write

Hi again,
These are my fstab settings

I just realized that /var/log/messages is the standard name used by the system loggers.. not a directory .. did you change the default log file name in /etc/rc.conf ? maybe there is an error in your choice of name

[saturnus]

Hello again,

yes I did. First I did some settings (maybe they are not right?) and then I got these messages. I also removed rc.log and as a result a new rc.log file was created.
Thank you for taking your time with this problem.

These are my settings in rc.conf:

# Global OpenRC configuration settings

# Set to "YES" if you want the rc system to try and start services
# in parallel for a slight speed improvement. When running in parallel we
# prefix the service output with its name as the output will get
# jumbled up.
# WARNING: whilst we have improved parallel, it can still potentially lock
# the boot process. Don't file bugs about this unless you can supply
# patches that fix it without breaking other things!
rc_parallel="YES"

# Set rc_interactive to "YES" and you'll be able to press the I key during
# boot so you can choose to start specific services. Set to "NO" to disable
# this feature. This feature is automatically disabled if rc_parallel is
# set to YES.
#rc_interactive="YES"

# If we need to drop to a shell, you can specify it here.
# If not specified we use $SHELL, otherwise the one specified in /etc/passwd,
# otherwise /bin/sh
# Linux users could specify /sbin/sulogin
rc_shell=/sbin/sulogin

# Do we allow any started service in the runlevel to satisfy the dependency
# or do we want all of them regardless of state? For example, if net.eth0
# and net.eth1 are in the default runlevel then with rc_depend_strict="NO"
# both will be started, but services that depend on 'net' will work if either
# one comes up. With rc_depend_strict="YES" we would require them both to
# come up.
#rc_depend_strict="YES"
# By default we do not allow hotplugging.
# A hotplugged service is one started by a dynamic dev manager when a matching
# hardware device is found.
# This service is intrinsically included in the boot runlevel.
# To disable services, prefix with a !
# Example - rc_hotplug="net.wlan !net.*"
# This allows net.wlan and any service not matching net.* to be plugged.
# Example - rc_hotplug="*"
# This allows all services to be hotplugged
#rc_hotplug="*"

you have a duplicated entry in /etc/rc.conf two references to rc_log_path="/var/log/rc.log" plus compared with mine it is missing stuff ..

Looks like one of your edits went a miss .. the default rc.conf is as follows:

I rolled back to the default values in rc.conf, but I still get those messages.

Try

[krinn]

As your root file system is mount RW
As your file set as RO is message

I then think you use syslog-ng, and that you have install syslog-ng in the boot process instead of the default one. Next to that syslog-ng is start before your root is remount RW and cannot then write to message.

Please check you get answer like this :

[RazielFMX]

I also get /var/log/rc.log not found on shutdown (and that I supposedly have an orphaned file under /lib64/rc/init.d called rc.log). I think the message is a code bug as I have nothing under that directory called rc.log:

[tristen]

Upon startup I get:
* Error fopen(/lib64/rc/init.d/rc.log) failed: No such file or directory

I have no idea why it's even trying to open that file. It doesn't exist on my machine,
nor is it specified in any of my config files in /etc.

[azmulx]

Is it possible that those kind of messages are caused by full filesystem?

[poncho]

Maybe related:

Bug 390645 - sys-apps/openrc: /var/log/rc.log is written before fsck/localmount

[RazielFMX]

I think openrc should dump the shutdown log prior to file systems being unmounted; whatever happens after that just won't be logged. Given the data in previous posts, it appears that the log is trying to be dumped even after the root partition has been remounted RO so even if rc.log is on the rootfs we will still see this issue. Thus, I think the only viable option is to sacrifice the last few lines of shutdown and dump the log prior to dropping the mounts and remounting rootfs readonly.

[hujuice]

Messages could also be stored in a temporary file and appended to /var/log/rc.log during the next startup.
Cold management (e.g. with a live) should be aware of this, but it would be complete.

That's the actual solution (/lib64/rc/cache/rc.log, the error message is wrong).
Simply, openrc could restore that content in the usual file.

HUjuice

FYI,

I was facing this problem, I solved by adding localmount & mtab to sysinit

rc-update add localmount sysinit
rc-update add mtab sysinit

[wcg]

Keep in mind that "/lib/rc/init.d/" (or /lib64/rc/init.d) is a tmpfs mount
where openrc keeps state information on the running system. When
you shutdown, the contents simply disappear, and when the system
boots again, they are created anew. If the system dumped a temporary
copy of a log file to that filesystem during shutdown, it would be gone
when the system rebooted.

[hujuice]

[wcg]

Consider also what happens if openrc finds itself running on a kernel
that has not been compiled with tmpfs support enabled. Then the
data in /lib/rc/init.d/ will likely find itself on persistent storage, and
that would work as an alternate log location.
