[Gluster-users] NUFA + replicate

[Gururaj K]

Hi Dave,

Please note that there is an error in your config file. The volumes "replication" and "cluster" are unused. (Note the error messages in your client logs about the volumes "dangling"). It is indeed possible to have either server side or client side replication with nufa.

Thanks,

Subject: Re: [Gluster-users] NUFA + replicate

I am using the following config, but replication does not appear to be
taking place between the nodes. If I take down the node the file was
created on, the other nodes can not see it. My only idea is that once
it sees the nufa translator, it does not recognize the other volume
types. If this is so, is there any way to have replication with nufa?

Anyone have thoughts? Config below:

Thanks in advance.
