Re: [Linux-cluster] using lacie ethernet disk raid as shared storage



Hi Gordan, 

thanks for your answer, 

I can mount this disk with NFS (also with CIFS but I´m not using this protocol) 

My idea was to mount the disk with NFS on the 2 nodes of a red hat cluster, but I don´t know if it is a good idea. (perhaps no :-( )

The cluster are going to serve a HA httpd service (I know, with this disk I have a SPOF, but that is all I have, no money for more .-(( )

any suggestion with this scenario?

Thanks again, 

ESG

I don't imagine for a moment that any of those would be supported,
considering the target audience is unlikely to ever have heard of those
protocols. It's likely to give you SMB/CIFS and nothing else. There's no
reason why you couldn't use it for shared storage, but that is in no way
related to RHCS.

Also remember that a single SAN/NAS of whatever description is still a
single point of failure, which makes a mockery of the concept of HA. This
is also (shockingly) a point (willfully) overlooked by most administrators
and architects.
