[Gluster-users] self-heal not working

[mabi]

Hi Ben,

So it is really a 0 kBytes file everywhere (all nodes including the arbiter and from the client).
Here below you will find the output you requested. Hopefully that will help to find out why this specific file is not healing... Let me know if you need any more information. Btw node3 is my arbiter node.
