Full uninstall ?

[SyncoveryLG]

Ive been struggling for months on end to keep Sycovery on my Synology NAS stable. It runs for a short while and then it stops running jobs, and I can't login. Have to restart the task on the NAS then sometimes I can log in and jobs are running again, but within a day they stop again - rinse repeat. Sometimes I have to reboot the NAS. About a week go that procedure stopped working for me and I can no longer login. I can get to the NAS on port 5000 just fine but 8999 no longer lets me login. Restart/reboot - no help anymore. Task is running fine on the NAS. Dobule-checked Syncovery user was setup right. Upgraded a few minor revisions from 9.49e to 9.49g. No help. Even tried uninstalled the app on the NAS and reinstalling it. Still can't log in. It's a constant ERR_CONNECTION_REFUSED. Tried Edge (which I never use) instead of Chrome. Same thing. At wits end.

Oh - turned off all Chrome extensions. Disabled firewalls, etc etc. No problems getting to port 5000 but can't login to port 8999 in same browser different tab.

Is there a procedure to do a full uninstall of Syncovery on the NAS, other than just going into package manager and uninstalling it? I don't know what else to try. If I can't get it functional again I'll have to try other software which I really don't want to do as I really like Syncovery. It's ran for me great on Windows 10 desktops.

Or perhaps I can try resetting the Syncovery user password. I can SSH to the root but I can't find the program folder the app is installed in to be able to do the reset.

So did find my way to SyncoveryCL:
/volume1/@appstore/Syncovery/usr/bin
Have tried
bin/SyncoveryCL SET /WEBSERVER=localhost /WEBUSER=Syncovery /WEBPASS=mynewpassword

20:29:20 SyncoveryCL v9.49g
Reading config file /volume1/@appdata/Syncovery/SyncoveryCL.conf
Temp folder from /volume1/@appdata/Syncovery/SyncoveryCL.conf: /volume1/@apptemp/Syncovery
20:29:20 Initializing
20:29:20 Log folder: /volume1/@appdata/Syncovery/Logs
20:29:20 Configuration File: /volume1/@appdata/Syncovery/Syncovery.cfg
20:29:20 Storing global settings:
20:29:20 Configuring web server for localhost, port 8999.
20:29:20 Web Docs Path: /volume1/@appstore/Syncovery/usr/bin/WebDocs
20:29:20 Username: Syncovery
20:29:20 Password: (hidden)

That hasn't helped, either. ERR_CONNECTION_REFUSED continues.

Hello,
do you have DSM 6 or 7?

In an SSH connection, to fix the web GUI, please follow these steps:

Code: Select all

sudo killall -9 SyncoveryGuardian
sudo killall -9 SyncoveryCL
cd /volume1/@appstore/Syncovery/usr/bin
./SyncoveryCL SET /WEBSERVER=localhost /WEBUSER=Syncovery /WEBPASS=mynewpassword

And next, we will run SyncoveryCL in the terminal session to see its output:

Code: Select all

./SyncoveryCL

The output should be like this:

Code: Select all

02:33:56 SyncoveryCL v9.49e

If your output contains an error instead, please post it here.

Now you can try it. If it works, that's one step forward. But since you don't want to leave the terminal open all the time, we do need to stop SyncoveryCL once more (this was just a test) and start it as a daemon.

Hit q and Enter in the Terminal. Wait until the shell prompt appears.

Enter

Code: Select all

./SyncoveryCL start

This starts SyncoveryCL as a daemon and you can now close the SSH connection.

On the other hand, if you want to make a full uninstall, please make a copy of your Syncovery.cfg first (/volume1/@appdata/Syncovery/Syncovery.cfg) and then uninstall it using the Synology app center.

Then you can use SSH to remove any remaining files:

Code: Select all

rm -R /volume1/@appstore/Syncovery
rm -R /volume1/@appdata/Syncovery
rm -R /var/packages/Syncovery

You can import your old profiles from your copy of Syncovery.cfg using the web GUI by right-clicking in the profile list area.

DSM 7

When running ./SyncoveryCL "If your output contains an error instead, please post it here."

Looks like it's having trouble reading from the SQL db? I'm suspecting it's the password. I used a random 16 character with special characters and I see it has an & in it, which throws SSH command line when I tryu and set it, as in this example:

./SyncoveryCL SET /WEBSERVER=localhost /WEBUSER=Syncovery /WEBPASS=pass&word

I tried escaping it with the & hex code but did not work

./SyncoveryCL SET /WEBSERVER=localhost /WEBUSER=Syncovery /WEBPASS=pass%26word

I tried to set it to something simple, like this:

./SyncoveryCL SET /WEBSERVER=localhost /WEBUSER=Syncovery /WEBPASS=mypassword

but it's still dying on the SQL access.

Perhaps a full uninstall is next. I have the profiles saved as exported files so not a big deal to reconstruct.

Hello,
yes, it could be that your Syncovery.cfg file is corrupt. The full path is:
/volume1/@appdata/Syncovery/Syncovery.cfg

If you rename this file, Syncovery will use the previous backup. It might be sufficient to get it working. Unless the backups are also broken, in which case you may need to rename or remove the whole folder /volume1/@appdata/Syncovery. If you do that however, I would recommend installing the Syncoverey package again with DSM7 so that all the initialization is done properly.

[SyncoveryLG]

I ended up having to delete everything I could find. I figured at this point sinc eI have the profiles backed up, I may as well start with a clean slate.

rm -R /volume1/@appconf/Syncovery
rm -R /volume1/@appdata/Syncovery
rm -R /volume1/@apphome/Syncovery
rm -R /volume1/@appstore/Syncovery
rm -R /var/packages/Syncovery

Then a fresh install of latest version got it going again

I'll add these procedures to the operations manual for future reference. Appreciate the help!

[tobias]

Hello,
thanks for the information.

I have released Syncovery 9.49i for Linux today, which includes a fix for a possible internal lock-up / hang. Maybe this was part of your problem. It may have caused the web GUI to become inaccessible.

I recommend updating Syncovery once more. You can just install the new package over the existing one.

Thanks!

[SyncoveryLG]

OK. I'll update to the latest. So far almost everything seems stable

There are profiles that run every 15 minutes that have been running fine. However, I have 12 profiles set to "Run Every Day" at 07:00:00 that are acting odd. They are all behaving the same way. They work just fine, it's the profile status screen that is off.

The Last Result or Progress / Last Run stats on the overall profile screen do not reflect the most recent actual run.

I logged out and back in and refreshed.

On the status screen it currently says:
Last Result or Progress = "Nothing to do" - correct
Last Run = "Yesterday, 20:42:31" - correct, I manually ran it last night.
Next Run = "Tomorrow, 07:00" - correct

I open the log for it and it cleary shows that it ran. I would think the status screen would now show:
Last Result or Progress = "1 copied, 1 renamed"
Last Run = "Today, 07:00:15"
Next Run = "Tomorrow, 07:00"

Some highlights from the log (a bit sanitized):

Did you try the "Refresh" button?

Usually I recommend not keeping the Syncovery web GUI open.

[SyncoveryLG]

I've gone through the full uninstall procedure again after it started acting up again after I imported my original profiles.

This time I completely started from scratch, making one profile from scratch each time and testing as I went.
So far things have been running smoothly and I am up to 18 profiles.
This NAS had McAfee AV on it and I uninstalled that completely before this latest attempt. I'm thinking that may be a contributing factor in my woes. The only other thing I have not done is go beyond 20 jobs to force the web gui to need to deal with more than one page. Wanted to wait on that hail mary until all of the logs were clean and things were stable.

That being said I left town for the weekend and came back, logged back into the web gui, and checked the logs. Things were still running so that's good

Some of the logs are experiencing a "database is locked: bad parameter or other API misuse" error hitting the SQL database so now I'm trying to figure out what that is about. Those five jobs all run once an hour at 45 minutes after the hour

I did not leave the web gui open. In fact, the PC I had been using to manage Syncovery had been totally asleep and I had logged out of Syconvery when I left it.

I don't have any of the Special/Database tab entries in the profile configuration filled in.

It does not seem to effect what appears to be the first job (they seem like they are running in alphabetical order). The fifth job looks like it experiences the error the most but not always. I'll guess that if one of the jobs is already running when another one kicks off it has this problem, which is odd considering sql databases should be multi-user.

Here is one of the (sanitized) logs:

One other thing I have been experiencing is, sometimes when I edit an existing profile and save it, or simply just click the REFRESH button, the profile screens shows blank for all profiles and the "Loading" progress icon comes up. Usually the refresh happens right away. I let it sit at "Loading" for several minutes before finally closing the tab and logging back in, and then it comes up with a blank profiles screen "No data to display" (see screenshots)
After a number of attempts to log back in I eventually got all of the profiles displaying.

Then it happened again and this time it too a lot longer to get back to displaying the profiles.

I've also tried refresh.

Now it's back to not being able to save a profile - argh! All I did was enable the schedule on it. wtf - this is beyond frustrating

Maybe it's related to this rather constant Syncovery.cfg dance that I'm seeing in those logs in my prior post.

15:45:12 Copied /volume1/@appdata/Syncovery/Syncovery.cfg to /volume1/@appdata/Syncovery/Syncovery.cfg.bak (180224 Bytes)
15:45:12 Copied /volume1/@appdata/Syncovery/Syncovery.cfg to /volume1/@appdata/Syncovery/CfgBackups/Syncovery.cfg (12-25-22 15.45.12) (180224 Bytes)

So I poked around in /volume1/@appdata/Syncovery and there's a crapload of Syncovery.empty.bak... files (see attached SyncoveryEmptyBAK.jpg). I think this may be important. At some point that Syncovery.empty.bak.old.old.old..... filename length will be a problem,. The last entry is 253 characters long so I am thinking another .old will make it 257, and once we hit 256+ we've got a problem, Houston.

BUT, THOSE ARE ALL FROM YESTERDAY, NOT TODAY and it was running ok until just a little while ago. So maybe not
Still, whatever is causing that, doesn't look good.
