A reader (M.R.) contacted me asking about running Symform on his Synology DS3611xs. He later uninstalled it and found that the SymformContribution folder was getting recreated at every reboot.
After a number of email exchanges, he was able to get Symform to confirm it was a bug:
Thank you for contacting Symform support. I understand that you are having an issue with the SymformContribution folder being re-created after you have un-installed Symform, and rebooted the DiskStation.
I have been able to reproduce this issue, and found that it is re-created due to the folder listed as a Shared folder in the Synology Shares section.
I have sumbitted an internal bug ticket to my developers to look into this issue. From what I found, it is just re-creating the folder, and the Symform services are not present, or running.
The commands to fix it follow, but I’ve updated step 3 to an absolute path:
1. Here is the command to view the Synology shares table:
/usr/syno/sbin/synoshare --enum ALL
2. If you see the SymformContribution folder listed, enter in the following command:
/usr/syno/sbin/synoshare --del TRUE SymformContribution
3. Then, to remove the folder from the Volume1 folder, enter in the following:
rm -rf /volume1/SymformContribution
Adjust the path in step 3 if your contribution folder is on another volume.
Thanks again to M.R. for the information and legwork getting this resolved!
