    You don't say what version of the client (version of kernel, if it's
    the kernel client) this is.  It would appear that the client thinks
    there are some dentries that don't really exist.  You should enable
    verbose debug logs (with fuse client, "debug client = 20") and
    reproduce this.  It looks like you had similar issues (subject:
    "problem for remove files in cephfs") a while back, when Yan Zheng
    also advised you to get some debug logs.
