Description Shruti Sampat 2015-05-06 05:35:19 UTC

Description of problem:
------------------------

Running `ls' a directory that has some files with mismatching gfid's on both bricks of a replica pair, does not list anything. All entries in the directory should be listed regardless of them being in split-brain.

Version-Release number of selected component (if applicable):
---------------------------------------------------------------
glusterfs-3.7.0alpha0-0.17.gited96153.el6.x86_64

How reproducible:
------------------
Always

Steps to Reproduce:
-------------------
1. On a distributed replicate volume (with self-heal-daemon turned off), bring down one brick in each replica pair and create a file on the mount point.
2. Bring all bricks up and then kill the other brick in each replica pair (different from the one that was brought down earlier)
3. Create a file with the same name on the mount point.
4. Run `ls' on the mount point.

Actual results:
----------------

`ls' does not list any entries.

Expected results:
------------------

`ls' should list all entries in the directory.

commit 145f0ab3540fb922ecd109170a76c347c5dfad78

    afr: allow readdir to proceed for directories in split-brain
    
    Problem:
    afr_read_txn() bails out if read_subvol==-1. This meant that for
    directories that were in entry split-brain, FOPS like readdir, access,
    stat etc were not allowed.
    
    Fix:
    Except for getxattr, all other FOPS are wound on the first up child
    of afr.
