When a write request comes, EC internally reads some blocks using anonymous fd. This read will fail as the file has already been unlinked. Solution: To solve this issue, we are using .unlink directory to keep track of unlinked file. If a file is to be unlinked while its fd is open, move this to .unlink directory and unlink it from .glusterfs and real path. Once all the fd will be closed, remove this entry form .unlink directory.
