After moving ffp to a usb (at /mnt/usb/), certain things aren't working as they used to (when ffp was in /mnt/HD_a2/)

Specifically,
"crontab -l |sed -e '/rtc\ -c/d' -e '/daylight/d' -e '/rtc\ -s/d' | crontab -"

in fun_plug.local (full file below) doesn't remove the two lines in crontab.

As well as that, /ffp/start/editcron.sh, which used to add some lines to the crontab to enable regular time sync, doesn't work either.
It creates the file, but for some reason doesn't load it into crontab.

last but not least, alias ls='ls --color=auto' doesn't alias permanently as it did before - I have to run it each time. Putting that line into fun_plug.local doesn't work either.

Here's the kicker - if I run either of those commands/files mentioned above (the "crontab | sed" command, the editcron.sh or the alias ls command), they work. Just not in fun_plug.local or on start.

And yes, they have execute rights.

/ffp/etc/fun_plug.local

Code:

#!/ffp/bin/sh
PATH=/ffp/sbin:/ffp/bin
#PATH=/ffp/sbin:/usr/sbin:/sbin:/ffp/bin:/usr/bin:/bin
BINDIR=/ffp/bin
LOGFILE=/mnt/usb/ffp.log
ETCDIR=/etc


# Set local timezone
# For a list of timezone strings see:

# Australia - Melbourne, Camberra, Sydney
TZ=AEST-10AEDT-11,M10.5.0/02:00:00,M4.1.0/03:00:00
export TZ
echo ${TZ} >${ETCDIR}/TZ


# This removes firmware cronjobs that interfere with ntpd.
#crontab -l | grep -vw '/usr/sbin/daylight' | grep -vw '/usr/sbin/rtc' | crontab -
crontab -l |sed -e '/rtc\ -c/d' -e '/daylight/d' -e '/rtc\ -s/d' | crontab -

# executing the time protocol every boot to set correct time during boot up process
/usr/sbin/sntp -r -P no au.pool.ntp/org 1>>${LOGFILE} 2>&1 &

# added this in the hope that it would remove the necessity of aliasing ls with --color option each time. doesn't work.
alias ls='ls --color=auto'

/ffp/start/editcron.sh

Code:

#!/ffp/bin/sh

CRONTXT=/mnt/usb/crontab.txt

# start with existing crontab
/bin/crontab -l > $CRONTXT

# add a job to sync RTC with system time once per day
# and add a job that sets system time using SNTP hourly
/bin/echo "32 2 * * * /usr/sbin/rtc -w" >> $CRONTXT
/bin/echo "2 * * * * /usr/sbin/sntp -r -P no pool.npt.org &" >> $CRONTXT

# install the new crontab
/bin/crontab $CRONTXT

# clean up
/bin/rm $CRONTXT

Any ideas?

Cheers,
Klaus

This one should go into ~/.profile or /ffp/etc/profile: alias ls='ls --color=auto'

For the other mysterious issues, have a look at the end of ffp.log. Look for "* Running /ffp/etc/fun_plug.local ..."

From ./ffp.log (/mnt/usb/ffp.log) (not sure what this one is for...)

Code:

sntp: unable to locate IP address/number
sntp: Success
sntp: unable to locate IP address/number
sntp: Success
sntp: unable to locate IP address/number
sntp: Success
sntp: unable to locate IP address/number
sntp: Success
sntp: unable to locate IP address/number
sntp: Success
sntp: unable to locate IP address/number
sntp: Success

That's the whole log, which doesn't seem quite right to me.
as the line in fun_plug.local calling the sntp link (au.pool.ntp/org) is after the crontab line I'm not sure why that'd cause it to break?
(I am assuming that the line in fun_plug.local which calls the sntp update on boot is the one writing this error)

Meanwhile, in /mnt/HD_a2/.bootstrap/ffp.log

Code:

Aliasing ls works when put in /ffp/etc/profile, thanks for that

/etc/rc.sh starts crond well before it runs your fun_plug. But crond puts itself in the background and may run pretty slowly while the rest of /etc/rc.sh is running, including your fun_plug. It is possible that your crontab modification is happening before crond gets around to setting the default crontab. So crond is overwriting your crontab.

You probably changed the timing profile of all this by moving ffp to USB. The file access timing changed to the point where your fun_plug and crontab modifications beat crond. The read from USB may have been faster than off the hard disk, which may have been busy doing I/O for other tasks that were starting up.

This actually affects a lot of people, and it all depends on the timing and what fun_plug is doing.

Many people put a sleep for a few seconds in their script just before they modify the crontab, to let crond have a chance to get started.

Left /ffp/start/editcron.sh as is.

added "sleep 10" to /ffp/etc/fun_plug.local:

Code:

#!/ffp/bin/sh
PATH=/ffp/sbin:/ffp/bin
#PATH=/ffp/sbin:/usr/sbin:/sbin:/ffp/bin:/usr/bin:/bin
BINDIR=/ffp/bin
LOGFILE=/mnt/usb/ffp.log
ETCDIR=/etc

# sleep in order to let crond start properly so that it won't overwrite the changes made below
sleep 10

# Set local timezone
# For a list of timezone strings see:
# http://www.nas-tweaks.net/CH3SNAS:Tutorials/ntp#Appendix:_Example_Timezone_Strings

# Australia - Melbourne, Camberra, Sydney
TZ=AEST-10AEDT-11,M10.5.0/02:00:00,M4.1.0/03:00:00
export TZ
echo ${TZ} >${ETCDIR}/TZ


# This removes firmware cronjobs that interfere with ntpd.
#crontab -l | grep -vw '/usr/sbin/daylight' | grep -vw '/usr/sbin/rtc' | crontab -
crontab -l |sed -e '/rtc\ -c/d' -e '/daylight/d' -e '/rtc\ -s/d' | crontab -

# executing the time protocol every boot to set correct time during boot up process
/usr/sbin/sntp -r -P no au.pool.ntp/org 1>>${LOGFILE} 2>&1 &

result:

Code:

root@NAS:/mnt/usb/ffp/home/root# crontab -l
30  2  *  *  * /usr/sbin/stime&
*/60  *  *  *  * /usr/sbin/getdhcp&
32 2 * * * /usr/sbin/rtc -w
2 * * * * /usr/sbin/sntp -r -P no pool.npt.org &

= success!
Thanks Fonz & Karlrado
