TCE Persistence; Why can't I find my apps after booting
« on: June 16, 2017, 08:13:30 PM »
I've been reading this article, but still not sure about this situation.

Persistence for Dummies, or "Why can't I find my apps and settings after booting?"
http://wiki.tinycorelinux.net/wiki:persistence_for_dummies

Since HAproxy is not available on TCL 7.2, I've downloaded it manually from TCL 8 repo.
Code: [Select]
wget http://tinycorelinux.net/8.x/x86/tcz/haproxy.tcz
I've no issue with other apps such as tcpdump.

This is the comparison between tcpdump and haproxy.

-rw-r--r--    1 1001     staff          0 Jun 17 11:43 tcpdump
user@box:~$

I notice that haproxy is not in /mnt/sda1/tce/optional/ directory as I downloaded it manually using wget to home directory. However, even if move haproxy.tcz to /mnt/sda1/tce/optional/, it still doesn't change anything.

I still can't make haproxy persistence even though it has already been listed in onboot.lst

user@box:~$ grep haproxy /mnt/sda1/tce/onboot.lst
haproxy.tcz
user@box:~$

Your advise in this matter would be highly appreciated. Thanks

onboot.lst  doesn't provide any persistence features. It just lists what shall be loaded when booting.

If you move your custom extension to the tce/optional directory, I can imagine only one situation where your custom extension would be gone after reboot. That would be the Cloud-Mode, where extensions are downloaded to a tce directory in /tmp, because, for example, the tce-dir wasn't found at boot.
Run
Code: [Select]
readlink /etc/sysconfig/tcedir
To find out if that's the case.

tc@box:~$

Installation Process: Before & After
Code: [Select]
tc@box:~$ haproxy
-bash: haproxy: command not found
tc@box:~$
tc@box:~$ tce-load -i haproxy.tcz
haproxy.tcz: OK

        -n sets the maximum total # of connections (2000)
        -m limits the usable amount of memory (in MB)
        -N sets the default, per-proxy maximum # of connections (2000)
        -p writes pids of all children to this file

So the extension is actually there but just not loaded.

If you still have it in your user's home directory, it will be loaded from there if you issue the  tce-load  command while in your user's home directory. It won't be found while booting.

If you have copied it to  /mnt/sda1/tce/optional  and removed it from your user's home directory, it will be loaded from the intended extension storage and it will be found at boot.

Maybe you made a typo in your onboot.lst file.
Also note the last line must be blank.

That's right. I've to manually run tce-load -i haproxy.tcz if I need to run the app.

If you still have it in your user's home directory, it will be loaded from there if you issue the  tce-load  command while in your user's home directory. It won't be found while booting.

If you have copied it to  /mnt/sda1/tce/optional  and removed it from your user's home directory, it will be loaded from the intended extension storage and it will be found at boot.

Maybe you made a typo in your onboot.lst file.
Also note the last line must be blank.

BEFORE REBOOT
1. I've moved haproxy.tcz from home to /mnt/sda1/tce/optional/ directory
2. There is no space in onboot.lst.

AFTER REBOOT
Weird, I did the same steps before but it didn't work.
Somehow it's working this time  :)
