Server outage, file sync/self-heal doesn't sync ALL files?!

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

 



hi Martin,
      Could you please send the output of -m "trusted*" instead of "trusted.afr" for the remaining 24 files from both the servers. I would like to see the gfids of these files on both the machines.

Pranith.

Hi all!

We have another incident over here.

One of the servers (pserver12) in a pair (12 & 13) has been rebooted.  
pserver13 showed 63 files not in sync after the outage for 2h.

Both server are clients as well.

Starting pserver12 brought up the self-heal mechanism, but only 39 files 
were triggered within the first 10 min. Now the system seems dormant and 
24 files are left hanging.

On the other three servers no inconsistencies are seen.

I could trigger manually but why isn't the sync/self-heal not working on 
all files shown as inconsistent? Or am I assuming something wrongly here?!?

Best, Martin
