By changing the exit 1 to exit 0, the package center showed 'running', which allowed dependent packages to install. This wasn't happing in earlier version of DSM. Because MinimServer is running fine (only the reported status is wrong) I though about as a similar issue.

This appears to be a different issue. MinimServer has two states: "running" and "stopped". Python has a single state, which was previously set to "stopped" but has now been changed to "running".

in this thread they suggest that the python package should emulate that it is running. this is required due to the more restrictive dependency rules in the dsm 4.2 package center. btw, the more proper fix for the python package would probably be to set the startable key in the INFO file to false. however, this has nothing to do with your issue.

the minimserer package should report its status correctly. i'm running minimserer 0.63.4 with dsm 4.2 without problems. my guess is that you have a somehow corrupted minimserver installation and thus a fresh install might help. if not, we have to investigate this further.

4) install minimserver without the option to start it afterwards
5) restore minimserver.config
6) start/stop the package a few times and observe the status in the package center. also make use of the refresh button.

thanks!

Followed these steps exactly, but the status remains 'stopped'. With MinimWatch I see in the log that MinimServer works, so it's not a biggie.
Thanks.

Thanks for trying this! Unfortunately, I'm not able to reproduce this. However, I'm very interested in the reason for your specific problem. Please answer the following questions:

1) Which Synology NAS model do you have?
2) Did you ever try a manual MinimServer installation, this means without the package center?
3) Did you ever install MinimServer on a different volume than volume1, which is the default?
4) If you are famililar with telnet/ssh, please logon to your NAS as root and post here the output of the following command:

Code:

ps -w | grep minim

Many thanks!

Is it normal to run so many instances of minimserver.ja ?

Thanks!!!!!

Hi, thanks for this very helpful information and no, so many instances of MinimServer are not normal Smile

. In fact, there should be just one.

I wasn't even aware that there is an official package 'Java Manager' from Synology. This package isn't available for my NAS (DS211) and I dind't find much documentation for it. Am I right that this package is just about installing Oracle Java at the NAS?

Basically, the MinimServer package is optimized to work with the Java package by patters (please see the MinimServer installation guide for more information). However, it is designed to work with other kinds of Java installations also. Since you use an official package from Synology, this should definitely be supported, too.

The problem is that the status check is performed by matching the output of ps, just as you posted it and the current package requires the string 'minimserver.jar' to be there. Your output is truncated to '... minimserver.ja'. This is due to the longer path of the java executable with the 'Java Manager'. So, the package center always thinks that MinimServer is stopped and with pressing run you add another instance and you will get an error message like mentioned in your initial post.

This will be fixed in the next version of the package. To fix it yourself now, you have two options:

First option: Uninstall the Java Manager and MinimServer. Reboot your NAS. Install the Java package by patters and MinimServer.

Second option: Edit the file '/var/packages/MinimServer/scripts/start-stop-status' and change line 10 from

Code:

ps -w | grep "^ *[0-9]* minimser.*java -jar.*[m]inimserver.jar" > /dev/null

to

Code:

ps -w | grep "^ *[0-9]* minimser.*java -jar.*[m]inimserver" > /dev/null

Important: Reboot the NAS.

I recommend the second option. When you get it working with this, this confirms my presumption.

Thanks!

Edit: if you choose option two, you should also change lines 91, 130 and 150 from

Code:

PID=`ps -w | grep "^ *[0-9]* minimser.*java -jar.*[m]inimserver.jar" | awk '{print $1}'`

to

Code:

PID=`ps -w | grep "^ *[0-9]* minimser.*java -jar.*[m]inimserver" | awk '{print $1}'`

I've seen this when using old libraries (libc, glibc) that don't support pthreads. If LinuxThreads are being used instead of pthreads, you'll see a separate process for every MinimServer thread. Perhaps Java Manager contains some libraries that are based on LinuxThreads.

Thanks for this interesting pointer!

@Rairwave: you can test this by
1) rebooting the NAS.
2) pressing 'run' for MinimServer in the package center just once.
3) If the output of 'ps -w | grep minim' still shows several java processes, this confirms the assumption from Simon.

If this turns out to be true, there have to be applied more changes to the package scripts to make it compatible with the Java Manager. In this case we will provide you with a test package soon.

The first and second ps command were right after the reboot, the third was after I started minimserver.

The reason for making use of Synology's new Java Manager is because it allows for faster upgrades of Java which solve recent security issues.

Yes, from what I understand is that the Java Manager is just for installing Java on your NAS:
"Java Manager helps you to install JDK and JRE on your DiskStation to run business applications. .....
Java Manager and Tomcat are available on the models: RS10613xs+, RS3413xs+, DS2413+, DS713+, DS3612xs, RS3412RPxs , RS3412xs, RS2212+, RS2212RP+, DS1812+, DS1512+, RS812RP+, RS812+, DS712+, DS412+, DS3611xs, RS3411RPxs, RS3411xs, RS2211RP+, RS2211+, DS2411+, DS1511+, DS411+II, DS411+, DS1010+, RS810RP+, RS810+, DS710+."

I confirm these edits work. Package Manager is now showing MinimServer as running, straight after a reboot.
(Still with 29 java processes, but that is a different matter I know)

Thanks for your help on this one, I am happy!

Edit: line 91 should be 97, changed in above guideline.
