There was some noise made about it a while back, but I haven't seen any announcements. Could have missed it, though. Be aware that both AFS and GPFS take significant planning and implementation is not trivial for either. On the other hand, there are significant benefits for non-Z systems for both. > 2) is anyone doing any significant file system sharing across > FCP-attached disk on z/VM? if so, what are you're experiences, good , > bad, otherwise? We've done some with OCFS and some with GFS (as you well know...8-)). OCFS seems to do OK for small (2-3 node) clusters that are connected to or near the same segment. Same with GFS. AFS does better with distributed systems, but has some semantics differences that can cause some applications problems. I think the support for AFS is better than for OCFS or GFS (naturally); most of the distribution vendors don't understand any of the three very well. ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
