I agree with all Paul's points. On this one, something I notice as people
report problems with files is that we're asked to run very cryptic shell
utilities to check the state of the extended attributes. Why not wrap these
in some Python, along with a few of the ways that are suggested to trigger
self-heal? You've got a vastly simplified initial setup for Gluster,
compared to similar filesystems. But then for maintenance you're basically
asking people to do it by hand - with neither comprehensive documentation of
how to do that the hard way, nor simplified utilities do it more easily. If
it never broke, this would be fine. But filesystems - even more basic and
mature ones - break all the time.
So assume it's going to break, and make sure the tools to deal with that are
readily available and usable by a sysadmin at 4 in the morning, who may not
have time to go to this list, or file a bug report and wait for response,
before fixing the problem for users.
