I have some trouble with my hard disc. After a "Contact support" problem I installed the disc builder image, run it, reinstalled the empeg 2.00b13 sw with hijack 3.40, preinit, mkprgpt and so on. But the hard disc does not work correct. See the follwing boot sequence:

Some files are not accessable (error: read-only) although I have set rw. Scripts are not executed, ...

When forcing a check media with jemplode I get the following:

When pressing CTRL+T during boot I get all O.K. with the hardware.

When trying to follow the hand work file check (as mentioned in the FAQ) I get errors with /dev/hdc4.

When setting the drive to rw I get an read-only error while accessing for instance config.ini, when setting the drive to rwm it works.

Does anybody have an idea with that problem?

Are they executeable? ls -l should show ..rwx... in the permissions if they're rEADABLE, wRITEABLE and ExECUTABLE. Try 'chmod 777 [filename'] to set them read/write/execute-able...

ext2fs_check_if_mount: No such file or directory while determining whether /dev/hda4 is mounted.

IIRC this is normal - it looks for the /etc/mtab file for which filesystems that are mounted, but the empeg doesn't have/use that file.

This might be an issue with swap space - not sure... Search the FAQ for 'swap'

When trying to follow the hand work file check (as mentioned in the FAQ) I get errors with /dev/hdc4.

Do you have two drives? According to the boot log only one drive /dev/hda is found. You can't fsck a drive you don't have or the system for some reason doesn't see.

When setting the drive to rw I get an read-only error while accessing for instance config.ini, when setting the drive to rwm it works.

I believe the config file lives on the music partition, which is mounted red/write by the rwm command, the rw command only mounts the system partition as read/write.

/Michael

Thanks for the response.

The scripts M10, M20, ... are not marked as executable and should not. But the scripts M30, M50 and N10 are marked as executable (chmod 755) but are not executed.

My configuration is a single hard disc.

With the swap file I have no idea, found nothing useful in the FAQ.

When trying to access files in the programs0 folder whether rwm nor rw helps. The error message is alsways read-only.

Anything else I could try?

Where is your programs0 folder?

I have used mkprgpt to create programs0, so it is at /dev/hda2:

mount -n -r -t ext2 /dev/hda2 /programs0

Fossi

Hmmm... Why does that mount -r bother me... I do not have a man page handy - is that a read only flag?

is that a read only flag

Yes.

I don't see any messages indicating hard disk problems in that log.

But it does look like "low memory" issues or something. Some app you have installed is taking too much memory away from the player. There's a config.ini parameter for "reserved cache" or some such thing, described in the FAQ, which will likely help here.

-ml

Now I set ReserveCache=30 and tried again.

The log while trying to force check media:

e2fsck 1.19, 13-Jul-2000 for EXT2 FS 0.5b, 95/08/09
ext2fs_check_if_mount: No such file or directory while determining whether /dev/hda4 is mounted.

Vital Signs says:
Cac: 1223,Buf:81,Fre:102


The problem remains. Scripts don't start, while trying to remove a file in programs0 directly after rw and rwm I get the error:

empeg:/programs0# rm gpsapp
rm: remove write-protected file `gpsapp'? y
rm: cannot unlink `gpsapp': Read-only file system

Fossi

Okay.

/programs0 is a filesystem that you created. If you look carefully at rw and rwm, they only cover the root and music partitions (unless you modified them). That is your likely problem for the read only aspect of things.

O.K., that worked (with rwp) - but I don't understand why it worked before with rw ...

But what does not work is still the executing of preinit scripts although they are located right and marked executable.

Any idea?

Fossi

Do me a favor. Go to /programs0, and do an "ls -al" and paste the results. Also, paste one of the scripts (if they are ascii). Thanks.

Here we go:

Fossi

Give this a shot:

(make your programs0 read/write)
cd /programs0/preinit.d
chmod 777 M*

No, don't do that - it'll increase your boot time somewhat as all the preinit scripts load, check whether their application exists and then bail.

preinit is clever enough to ignore unexecutable scripts, as shown by your log. At one point it wasn't - I assume that your running a recent version. I don't think that it has changed in ages though. so you probably are. We use permissions to decide what is going to run - this made it possible for mkprgpt to provide a bunch of scripts for various applications that could then be tweaked fairly easily, without anyone having to vi them from scratch. I would suggest that the M30emptriv permissions are wrong (based upon a previous post listing which scripts should execute) and need to chmod'd;

chmod 755 /programs0/preinit.d/M30emptriv


Aside from that, nothing in the log suggests that N10telnetd or M50gpsapp aren't executing. The log lists those scripts that didn't execute, and those weren't in that list.
Now, if you're testing in AC mode then gpsapp won't start. the 'incar' application is used to ensure that gpsapp only starts in DC mode. So you'll need to force DC power to see GPSapp on your hijack menu.
I suspect that telnetd is running. Why do you think it isn't?

Yep!

That was it. GPSapp does in fact only run when DC mode is forced (Didn't found it documented).

Telnet now also starts. After rebuilding my hard disc I didn't run "devs" which prevents telnetd from starting - this was documented, so my fault.

So both apps run again, many thanks for all your help.

The low memory issue was a very interesting one. Before rebuilding my player I had some mysterious effects which are reported sometimes here, like hang-ups of gpsapp in the long-run. Probably these effects are somehow linked ... we will see.
