This is because, the inode cache at node1's VFS is not flushed after node2
deletes the file. Hence when you cat, it does a lookup for the file, (with
the inode cache of vfs), but it got ENOENT (file not found) error, and the
inode cache is flushed after this.

AFR with NUFA ? I am not sure how did you managed to get schedulers working
with AFR. Schedulers are meant for scheduling creat(), and used *only* by
cluster/unify translator as of now.

Its a paranoid logging. We are working on reducing number of such logs.
