Gluster users - Aug 2013 - No active sinks for performing self-heal on file

Hello,

I'm seeing a lot of these in the logs. Can anyone explain what it means 
and how it can be fixed?

hi,
   Could you post the getfattr output for any of these files. If the afr
changelog xattrs are zero then this means that at the time of accessing a file
there were some pending transactions in progress, but by the time self-heal is
attempted, the transactions are completed so so need to self-heal.

Pranith.

Thanks for the logs Nux. Now that the issue is fixed, let us try to figure out
what lead to this situation for those two files.
Could you let me know when the server is rebooted.
