I found my Sync cannot work because of the problem "Folder not found".
My Sync version: "Resilio Sync 2.4.4 (732)".
I've read this article Sync > Errors & Troubleshooting> Errors > Folder Not Found, but my situation is different from what the article says. I neither delete nor move the folder.
Here is how the problem arise: I have a Windows and a Linux on my computer. I switched Linux to Windows and modified some files on the folder. Then I switched back to Linux then this problem arose.
Here is the information of the "rslsync" process:
$ ps -ef | grep rslsync
rslsync 5555 1 0 21:06 ? 00:00:09 /usr/bin/rslsync --config /etc/resilio-sync/config.json
"rslsync" is running under a user "rslsync", and it start automatically as the system is turned on.
The folder with problem is located on a NTFS disk, and it is mounted automatically on "/media"as the system is turned on. "rslsync" once had no permission to access the folder. To solve this problem, I use the following command, and I don't know whether this operation has any influence on the "Folder not found" problem.
chmod -R 777 /media
When I try to add folder in Sync, I can not found the folder mentioned above. But I can access the folder and the folder its father folder is "777".
If you have any idea, please help.
