DEBUG read_smb_spool: Directory created: / WARN read_smb_spool: Failed to create directory about greyhole HOT 1 OPEN

It shoudln't be a permission problem, since read_smb_spool executes as root, and thus should be able to create any folders it wants.

Does the folder /var/spool/greyhole/mem exist?

The read_smb_spool action is what reads the spooled files from /var/spool/greyhole/*, and insert those in MySQL as tasks for the daemon to execute.

If it finds a mkdir spooled task, it should log Directory created: $share/$path, then it should mkdir this folder on two storage pool drives identified as the metadata store backups, as $storage_pool_drive/$share/$path

So maybe check the folder in question, and try to mkdir that on all you storage pool drives manually, see if it works.
