[Ocfs2-devel] mount point is not unique among all nodes

[Sunil Mushran <sunil.mushran@oracle.com>]

The bug refers to a heartbeat2 issue.

So your qs is: Mount a ocfs2 vol on two nodes, A & B. Then on
node A, create a directory on the ocfs2 vol and then mount a
local filesystem on that dir. Then remove that dir on node B.

While I have not tested this, it will be a problem. We are relying
on vfs_rmdir() to call d_mountpoint(dentry) to nak the unlink.
But it is obviously not cluster-aware.

File a bugzilla. We'll have to think about a solution.
