Joe,
I don't think we have to accept this as this is not acceptable thing.
I understand your unhappyness with it. But its "free" and you sometimes
have to accept what you get for "free".
I have seen countless people complaining about this problem for a
while and seems no improvements have been done. The thing about the
ramdisk although might help, looks more a chewing gun. I have seen
other distributed filesystems that don't suffer for the same problem,
so why Gluster have to ?
This goes to some aspect of the implementation. FUSE makes metadata ops
(and other very small IOs) problematic (as in time consuming). There
are no easy fixes for this, without engineering a new kernel subsystem
(unlikely) to incorporate Gluster, or redesigning FUSE so this is not an
issue. I am not sure either is likely.
Red Hat may be willing to talk to you about these if you give them money
for subscriptions. They eventually relented on xfs.
