[Gluster-devel] Re-exporting NFS to vmware

[沈允中]

Hi, 
Thanks for the advice.
My problem is just like you said.
But is there any alternative way that I can solve my problem?
Because vmware really doesn't have the glusterfs protocol to mount.
I know that the Gluster.com may publish their VMStor product to improve this.
However, to tell the truth, I don't want to spend money.......:p

If the problem cannot be solved now, does anyone know other file systems which are similar to Gluster so that I can mount by nfs protocol without losing performance?
Thanks in advance.


Best Regards,
Sylar Shen

Are you saying you are mounting GlusterFS on an interim node, and then
re-exporting that via NFS? What are you using for the NFS export? Last I
checked kernel nfsd didn't work with fuse based file systems, so you'd
have to use something like unfsd (user-space) instead. You may, however,
find that if you do that, the extra performance hit from unfsd will undo
most of the speed-up you are hoping to achieve.
