Have anyone tried setting up a shared root cluster using OCFS2? There seems to be a lot of info etc. around doing this with GFS etc. but not much really with OCFS2... I got it to work sort of but I am running into an issue where rpm cannot open the rpm db (mmap fails)... Thanks -- WB
I tried it and had the same issue. Looks like there is no support for shared writeable mmap, and though a patch was floating around for a while, I never found it and I don't think it ever became officially supported. Last I knew, it was in the "someday" to do list. I was using debian, though, and my issue was with apt. But there are lots of programs that use shared writeable mmap so it became a show stopper for us. -----Original Message----- From: ocfs2-users-bounces@oss.oracle.com [mailto:ocfs2-users-bounces@oss.oracle.com] On Behalf Of Beukes, Wiekus Sent: Wednesday, October 24, 2007 4:31 PM To: ocfs2-users@oss.oracle.com Subject: [Ocfs2-users] Shared Root configuration Have anyone tried setting up a shared root cluster using OCFS2?

Hi, you should have a look at the open-sharedroot project (http://www.open-sharedroot.org/) . The purpose of this project is to provide an open and flexible filesystem based single system image (SSI) layer for linux clusters. Currently, GFS and NFS can be used as shared root filesystems. OCFS2 support will be added soon (as shared writable mmap support is available now :-) ). Keep checking for updates at http://www.open-sharedroot.org/news .
