Hello, AFR's selfheal maybe failed due to permission problem for example, a file on two node's permission is different, and need sync. a `lookup' will trigger this. But if the file's owner is root and you run `ls' with a normal user. Then the selfheal will be triggered but posix_chmod will fail because of the low permission. so `$ find /mnt/glusterfs -type f -exec head -c 1 {} \; >/dev/null' is not enough to sync the system, you need to run it as root. :) If any mistake, please point out, thanks.
