Hello Pranith, Thanks for your reply. I'm using 3.5.2.
Is it possible that Windows doesn't release the files after a write happens? Because the self-heal often never occurs. Just this morning we discovered that when a web server read from the other node, some files that had been changed days ago still had content from before the edit. How can I ensure that everything syncs reliably and consistently when mounting from SMB? Is Samba VFS more reliable in this respect?
