Dear all,
I was doing some testing regarding to GlusterFS link files (as they are created by a "move" operation). According to this document: https://www.gluster.org/glusterfs-algorithms-distribution/ If a link file is missing, it should be created after accessing the file.
However, I don't see this behaviour. If I delete (by hand) a link file on the brick, the file is still accessible, but the link file is never recreated. I can do an "open" or a "stat" on the file without getting an error, but the link file is not created.
Is this the intended behaviour? Or am I misunderstanding the above mentioned document?
You shouldn't access or modify the backend filesystems manually, you can accidentally create unexpected problems if you don't fully understand what you are doing.
That said, most probably the access to the file is still working because Gluster is using its cached information to locate the file. If the client mount is restarted, probably the file won't be accessible anymore unless you disable the "lookup-optimize" option (and this should recreate the link file).
Regards,
Xavi
best wishes,
Stefan
