Split brain; which file to choose for repair?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all! 

Is there anybody who can give some pointers regarding which file to choose
in a "split brain" condition? 

What tests do I need to run? 

What does the hex AFR code actually show? Is there a way to pinpoint the
"better/worse" file for deletion? 

On pserver12:

# file: mnt/gluster/brick0/storage/pserver3-19
trusted.afr.storage0-client-5=0x3f0000010000000000000000

On pserver13:

# file: mnt/gluster/brick0/storage/pserver3-19
trusted.afr.storage0-client-4=0xd70000010000000000000000

These are test files, but I'd like to know what to do in a LIFE situation
which will be just around the corner.

The Timestamps show the same values, so I'm a bit puzzled HOW to choose a
file.
