Description Xavi Hernandez 2015-01-30 10:58:59 UTC
+++ This bug was initially created as a clone of Bug #1187474 +++

Description of problem:

On a RHEL6.6 client, created two mounts, fuse and nfs. All the files and directories are created using fuse mount and when tried to list them using NFS, it doesn't show anything. But if absolute path of the file or directory is given it lists that.

It seems EC is receiving an OPENDIR request and before it has been completely processed, it receives a READDIRP request that fails with EINVAL.

I'll check what's the cause.

I tried this patch on release-3.6 and master, but can not write date in NFS client.Like this:

cp: failed to close ‘/mnt/glusterfs/xlators/cluster/ec/src/.deps/ec-helpers.Plo’: Unknown error 527

    ec: Special handling of anonymous fd
    Anonymous file descriptors need to be handled specially because
    they can be used in some non standard ways (i.e. an anonymous fd
    can be used without having been opened).
    This caused NFS to fail on some operations because ec always
    expected to have a previous successful opendir call (from patch
    This patch treats all anonymous fd as opened on all subvolumes.
    This is a backport of http://review.gluster.org/9513/
