LinuxFailSafe news

[Hergott, Jean-Philippe]

Hi 

You're absolutly right about GFS, I dowload fresh release 0.9.6
documentation and have a quick look inside. It seems now much more oriented
Fibre Channel and RaidArray boxes, anyway when I check supported hardware at
the present time. And fibre channel is an expensive technology. But more
awkward, for me, is that they are working know on new concept like 'scsi
export memory protocol' and I ask myself if they where ended, or at least
stable released, something.

What's about such a DLM, haven't you any idear about it in your ext3fs ?

Jean-Philippe.

DLOCKs are a necessary evil as long as we have no open-source
distributed lock manager.  With a DLM, we can toss DLOCKs.  (DLOCKs
have their own advantages such as platform-independence, of course, so
having the option of both is still good.)

GFS can already run its lock protocol over IP; it just lacks a proper
HA failover for that lock management right now.

It's definitely active --- look on the GFS mailing list if you want.
The people involved are now working under the auspices of a new
company, sistina.com, so if you mailed the old U.Minnesota addresses
the email may not have gone where you expeced...
