+++ This bug was initially created as a clone of Bug #1225491 +++ Description of problem: Figured while reading code that the function afr_final_errno() does not treat op_ret > 0 as success. What that means is that in inode write fops (where this function gets called by __afr_inode_write_finalize()), op_ret could be > 0 on success. And if the inode write fop failed on one or more subvols, there is a remote possibility that AFR, instead of choosing the most severe errno from the set of errnos returned by the subvolumes that saw a failure, winds up picking junk errno from the subvol where the fop actually succeeded.
