There should not be any mountpoint on a subdir in a brick. We can add a check in the fuse client to prevent this. The check would see if the mountpoint or any of its parent directories have the 'trusted.glusterfs.volume-id' extended attribute set. If so, that directory is the root of the brick and mounting should be prevented. This can get implemented in one, or both of: - xlators/mount/fuse/src/fuse-bridge.c - xlators/mount/fuse/utils/mount.glusterfs.in This has been fixed in mainline and 3.6 already. Bug 1040348 introduces additional warnings in the mount.glusterfs script. The patch at http://review.gluster.org/5931 can probably get backported easily. Maybe we should include some related improvements introduced by other patches as well. The version that this bug has been reported against, does not get any updates from the Gluster Community anymore. Please verify if this report is still valid against a current (3.4, 3.5 or 3.6) release and update the version, or close this bug. If there has been no update before 9 December 2014, this bug will get automatocally closed. |
