I found some similar threads to the message
Error while trying to start filesystem watcher for folder “xxx” (yyy), trying again in 1min: error while traversing zzz: permission denied
But no discussed solution helps finally.
The obvious solution with the Synology ACLs didn’t work either. It doesn’t matter whether with or without “+” at the end of the permissions, i.e. with or without Synology ACLs. The message mentioned appears anyway. But what amazes me:
- Only in some of the main directories, e.g. /volume1/subdirectory_1
- Only a few of the many main directories are affected, although they all have similar rights.
The corresponding main directories are also displayed as “current”. Everything seems synched.
