3.5.1

Release Notes for GlusterFS 3.5.1

This is mostly a bugfix release. The Release Notes for 3.5.0 contain a listing of all the new features that were added.

There are two notable changes that are not only bug fixes, or documentation additions:

1. a new volume option server.manage-gids has been added This option should be used when users of a volume are in more than approximately 93 groups (Bug 1096425)
2. Duplicate Request Cache for NFS has now been disabled by default, this may reduce performance for certain workloads, but improves the overall stability and memory footprint for most users

Known Issues:

• The following configuration changes are necessary for qemu and samba integration with libgfapi to work seamlessly:

  1. gluster volume set server.allow-insecure on
  2. restarting the volume is necessary

     gluster volume stop <volname>
     gluster volume start <volname>
     

  3. Edit /etc/glusterfs/glusterd.vol to contain this line:

     option rpc-auth-allow-insecure on
     

  4. restarting glusterd is necessary

     service glusterd restart
     

  More details are also documented in the Gluster Wiki on the [Libgfapi with qemu libvirt](../Feature Planning/GlusterFS 3.5/libgfapi with qemu libvirt.md) page.

• For Block Device translator based volumes open-behind translator at the client side needs to be disabled.

• libgfapi clients calling glfs_fini before a successfull glfs_init will cause the client to hang has been reported by QEMU developers. The workaround is NOT to call glfs_fini for error cases encountered before a successfull glfs_init. Follow Bug 1091335 to get informed when a release is made available that contains a final fix.

• After enabling server.manage-gids, the volume needs to be stopped and started again to have the option enabled in the brick processes

      gluster volume stop <volname>
      gluster volume start <volname>
