Re: [go-nuts] Re: mount remote storage without FUSE

['Axel Wagner' via golang-nuts]

Yeah, NFS would work as well (similar tradeoffs as 9P, though the linux
kernel driver might perform better because it's more widely used).

nbd is not suitable for the use case, I think :) I'd also recommend against
using my nbd package if performance is the goal - it is not at all
optimized, I wrote it mostly as a tool to test filesystem implementations
and things that depend on certain filesystem semantics.

[go-nuts] Re: mount remote storage without FUSE

[Didier Spezia]

One possibility is to use the 9P client of the kernel and implements a 9P 
server in Go - there are a few 9P libraries for Go around.
I doubt it will be more efficient than FUSE though, and btw FUSE is largely 
based on the ideas promoted by 9P.

Another possibility is to use the ndb client of the kernel and implements a 
ndb server in Go. See Axel's ndb package at https://github.com/Merovius/nbd
Now ndb exposes a block device, not a filesystem. I think I would be quite 
difficult to emulate the format of one the filesystems supported by the 
kernel and implements it in this Go ndb server.

Regards,
Didier.
