Description Ben Turner 2013-10-31 18:59:07 UTC

Description of problem:

Our BVT and FS Sanity tests are currently failing on the latest 2.1 u1 build with:

[2013-10-31 14:52:53.727404] W [client-rpc-fops.c:1170:client3_3_fgetxattr_cbk] 0-testvol-client-11: remote operation failed: No data available

All the failed tests that I saw had similar logs on the clients.  On the server side I see:

[2013-10-31 15:35:49.675693] W [posix-helpers.c:788:posix_handle_pair] 0-testvol-posix: Extended attributes not supported (try remounting brick with 'user_xattr' flag)

Has anything changed with how I need to mount bricks or is that warning a red herring?

Version-Release number of selected component (if applicable):

glusterfs-3.4.0.37rhs-1.el6_4.x86_64

How reproducible:

Every time I have ran automated tests on this build.

Steps to Reproduce:
1.  Compile the linux kernel on a glusterfs filesystem.
2.
3.

Actual results:

Compile fails.

Expected results:

Compile is successful.

For records:

This is indeed a glusterfs regression. Bad patch is a quota related commit which has broken rename() and link() calls:

    cluster/dht: instruct marker whenever it shouldn't do accounting

    This is needed for two reasons:
    * since dht-linkfiles are internal, they shouldn't be accounted.
    * hardlink handling in marker is broken. link/unlink of hardlinks
      present in same directory can break marker accounting. Hence, if src
      and dst are in same directory in case of rename, dht - if it breaks
      rename into link/unlink operations - should instruct marker to not to
      do accounting.

Comment 5 Ben Turner 2013-11-01 16:18:10 UTC

Verified on glusterfs-3.4.0.38rhs.  To note, I did see BZ 1025604 which still needs to be addressed, but the issues this BZ were opened for are resolved.
