[Gluster-users] Replica 2 cluster not replicating

[Marcus]

Some additional info:
I read somewhere that there has been a problem when the directory 
structures are too deep.
On my file servers there is a depth of 9-10 directories, is this still a 
problem?

The error I find in the error log is:
performing entry selfheal on 70764b1d-a022-4489-b7e1-df6073765d66
remote operation failed. Path: (null) 
(00000000-0000-0000-0000-000000000000) [No data available]

If I look in .glusterfs at the gfid on both machines I see that some 
files are missing on the second server.
But the content of .glusterfs matches what is stored in file structure, 
so there is not miss match there.

I have written a script that makes an ls on all files in the structure 
on a client.
This triggers a heal and the servers are busy working.
I am not done yet as this takes a while.
But this is not the way you are supposed to heal, right?

Best regarards
Marcus
