[Gluster-users] self-heal/possible split-brain problem...

[Thomas Besser]

Hi all,

have a gluster replica (3.1.4) over two servers.

client log says:

------------------------------------

The files on both server nodes looks like the same and both getting changed 
from the running VM on it! So perhaps only the extended attributes are 
wrong. 

Is there a way to change this manually? Without deleting the file on one 
side.

Also I'm confused about the last line of the client log, which telling me 
"data self-heal completed on /poolserver/hdb.raw". I would mean that this is 
a success message!?

Regards
Thomas
