[Gluster-users] [Centos7x64] Geo-replication problem glusterfs 3.7.0-2

[Kotresh Hiremath Ravishankar]

Hi Wodel,

Is the sync mode, tar over ssh (i.e., config use_tarssh is true) ?
If yes, there is known issue with it and patch is already up in master.

But it can be resolved in either of the two ways. 

1. If sync mode required is tar over ssh, just disable sync_xattrs which is true
   by default.

    gluster vol geo-rep <master-vol> <slave-host>::<slave-vol> config sync_xattrs false

2. If sync mode is ok to be changed to rsync. Please do.
    
    gluster vol geo-rep <master-vol> <slave-host>::<slave-vol> use_tarssh false

NOTE: rsync supports syncing of acls and xattrs where as tar over ssh does not.
      In 3.7.0-2, tar over ssh should be used with sync_xattrs to false

Hope this helps.

Thanks and Regards,
Kotresh H R
