pve + sa6400 SA6400 DSM 7.2.1-69057-1

Hello. I used to use hdd drive, to improve performance I added M2 drive, so I re-installed the app and migrated the database to M2 drive (done in synology system), after running normally for few months, But a few days ago photo app database was lost inexplicably, and today cloudsync also lost its database, but I re-entered photo, and found that its database is back to the same level as the day I lost it.

I want to use this tool to back up the databases stored on both hard drives to overwrite and restore my cloudsync, but when I run the tool, I get the following error

PLS help me,Thank you!

I have no idea what pve is.

Can you run this test script and tell me what it outputs? https://github.com/007revad/Synology_HDD_db/blob/test/sam_issue_111.zip

Is nodejs an old syno community package? Synology's node.js packages are name Node.js_v18, Node.js_v20 etc.

Your nodejs package does not have displayname or package in it's /var/packages/nodejs/INFO file. It's an easy fix.

But I am curious what information /var/packages/nodejs/INFO contains. Can you tell what this command outputs?

while read -r line; do if [[ ! $line =~ description|package_icon ]]; then echo "$line"; fi done <  /var/packages/nodejs/INFO

[yilin101]

root@NAS:~# while read -r line; do if [[ ! $line =~ description|package_icon ]]; then echo "$line"; fi done < /var/packages/nodejs/INFO -ash: /var/packages/nodejs/INFO: No such file or directory

The file doesn't seem to exist.

root@NAS:~# cd /var/packages/ root@NAS:/var/packages# cd nodejs/ root@NAS:/var/packages/nodejs# ls conf etc home scripts target tmp var

[007revad]

I wonder if the nodejs folder and symlinks were left over from an old version of nod.js that was previously uninstalled.

What do the following commands return?

ls /var/packages/nodejs/target
ls -l /var/packages/nodejs_v16
ls /var/packages/nodejs_v16/target
ls -l /var/packages/nodejs_v18
ls /var/packages/nodejs_v18/target
ls -l /var/packages/nodejs_v20
ls /var/packages/nodejs_v20/target

[yilin101]

It could be caused by having uninstalled it before.

root@NAS:~# ls /var/packages/nodejs/target app bin lib var root@NAS:~# ls -l /var/packages/nodejs_v16 ls: cannot access '/var/packages/nodejs_v16': No such file or directory root@NAS:~# ls /var/packages/nodejs_v16/target ls: cannot access '/var/packages/nodejs_v16/target': No such file or directory root@NAS:~# ls -l /var/packages/nodejs_v18 ls: cannot access '/var/packages/nodejs_v18': No such file or directory root@NAS:~# ls /var/packages/nodejs_v18/target ls: cannot access '/var/packages/nodejs_v18/target': No such file or directory root@NAS:~# ls -l /var/packages/nodejs_v20 ls: cannot access '/var/packages/nodejs_v20': No such file or directory root@NAS:~# ls /var/packages/nodejs_v20/target ls: cannot access '/var/packages/nodejs_v20/target': No such file or directory root@NAS:~#

[007revad]

If you go to "Package Center > Installed" are any packages showing as broken or need repair?

Check if any other packages are missing the INFO file:

for p in /var/packages/*; do if [[ ! -f $p/INFO ]]; then echo "$p"; fi; done

[yilin101]

Sometimes it prompts need repair, but not currently

root@NAS:~# for p in /var/packages/*; do if [[ ! -f $p/INFO ]]; then echo "$p"; fi; done /var/packages/CMS /var/packages/Chat /var/packages/DiagnosisTool /var/packages/MigrationAssistant /var/packages/PDFViewer /var/packages/git /var/packages/itools /var/packages/nodejs

[007revad]

Sometimes it prompts need repair, but not currently That is really strange.

I would uninstall then reinstall Central Management System, Synology Chat Server, Diagnosis Tool, git, Migration Assistant, PDF Viewer, itools and all Node.js packages.

When you uninstall git and Synology Chat Server make sure you don't tick the option to remove the data.

After uninstalling and reinstalling those packages the syno_app_mover script should run okay.

[yilin101]

Okay, I'll test it.

[yilin101]

I found that chat app that I can't delete because I can't find it in the software center, but the app exists on the homepage, which is very strange, and I think it should be caused by this app, do you know how to delete this app with ssh please?

[007revad]

sudo synopkg uninstall Chat

[yilin101]

I'm using the same command, but it doesn't work.

NAS:~# sudo synopkg uninstall Chat {"action":"prepare","error":{"code":0},"stage":"prepare","success":true}

use synopkg list ，Couldn't find the app either, which is likely what caused it.

Do you have a Windows PC?

When rm -f cannot delete a file, folder or symlink I use WinSCP's ui to browse to the file, folder or symlink and delete them.

[007revad]

Lets delete the symlinks that are pointing to volume2:

rm /var/packages/PDFViewer/etc
rm /var/packages/PDFViewer/share
rm /var/packages/PDFViewer/target
rm /var/packages/PDFViewer/tmp
