Why bother with a clustering FS, then, if you cannot actually /use it/ as one? - jra On February 19, 2014 10:44:22 PM EST, Jimmy Hess <mysidia () gmail com> wrote:On Wed, Feb 19, 2014 at 2:06 PM, Jay Ashworth <jra () baylink com> wrote:----- Original Message -----From: "Eugeniu Patrascu" <eugen () imacandi net>[snip] My understanding of "cluster-aware filesystem" was "can be mounted atthephysical block level by multiple operating system instances withcompletesafety". That seems to conflict with what you suggest, Eugeniu; am I missing something (as I often do)?When one of the hosts has a virtual disk file open for write access on a VMFS cluster-aware filesystem, it is locked to that particular host, and a process on a different host is denied the ability write to the file, or even open the file for read access.
Ghods how I miss real tightly coupled clustering, shared hierarchical storage and true clustered filesystems like in VMS. Here’s a 35 year old OS that still is better than anything we have today. Secure, granular prigs, file versioning, multiple simultaneous cluster interconnect physical layers, POSIX compliance, heavy distributed networking and strong system services built in. When people tell me about clustering today and then add these caveats about how clustered files aren’t actually sharable or that you can’t have complete orthogonality. I guess I’m now old. -d ----- Dan Shoop shoop () iwiring net 1-646-402-5293 (GoogleVoice)
