Vikas, Thanks you for responding. I am recommending that the first thing we do before spending more time troubleshooting this is to upgrade. I found that someone else reported something quite similar back in January. Here the "selfheal complete" is acutaly "selfheal complete unsuccessfully". It does not heal the file and open returns error. The healing code detects a conflicting case if it sees that both the subvols say that they are the latest and other is outdated. We see this happen when there is a split brain situation (network between AFR servers is broken and different clients write to each AFR independently) or in a very rare case where one of the servers go down right when a write operation is happening. I think you have hit the 2nd case. Here AFR can not really decide on which subvol has the latest version hence it leaves is to the discretion of the user. Earlier 1.3 AFR did not handle the split brain situation hence you did not see this. Krishna It seems to me that this must be inherent in the concept of a split namenode, namely that the potential for splitbrain exists. Is this no longer the case with gluster v2? Or if one host becomes unreachable for long enough, then this type of scenario is unavoidable? It looks like to upgrade, there is a post-install script that must be run on the exported volumes to clean up extended attributes. I haven't spent much time look at any upgrade docs yet (which I fully intend to do), but are there any big gotchas? The gluster servers house our production data storage, about 1.7TB on the average.
