[Gluster-users] "No space left on device" problem

[Julien Cornuwel]

Hi,

Maybe it's just a typo but your nufa volume refers to 'replicate3',
which doesn't seem to exist...

Anyway, I was wondering if it was possible to use nufa over replicated
volumes. It seems it is. I might set up such a cluster soon. Can you
tell me about the performances you get on it ?

Regards,
