Thanks Vikas, but how does it know that it's the first access for the file? Also what happens when somehow a file got deleted or corrupted on one of the servers? At what point will gluster replicate that file again?Before any operation can be performed on a file by an application, the kernel sends a 'lookup' call to the filesystem. The 'lookup' is what I meant by first access. Self-heal of a file also happens on a lookup if replicate detects that there's an inconsistency among the subvolumes.
