Does the storagenode log contain anything about trash-cleanup-filewalker or trash-filewalker. You can search this with grep -E "trash-cleanup-filewalker|trash-filewalker", if you have grep installed.
There could be few reasons that it’s not working, e.g.
- there’s some file that’s preventing the folder being deleted
- there’s some program that’s preventing it from deleted
- there’s some disk issue
- there’s some issue starting the program that cleans the trash folder
- there’s some bug/issue related to deleting the trash
- probably something that I cannot think of at the moment
And yes, trash that’s older than 10 days is safe to delete. However, this may happen again.
