On its own, clvmd just allows you to use the LVM2 tools safely in a shared storage environment - e.g. preventing you growing an LV on one node while you shrink it on another - it doesn't address actually getting the data synced between devices on separate nodes. There's some discussion of cmirror in the paper here: http://developer.osdl.org/dev/clusters/docs/cluster_summit_mirror_paper.pdf (a bit old, but has some useful background) And CVS is in the cluster repository: http://sources.redhat.com/cgi-bin/cvsweb.cgi/cluster/cmirror/?cvsroot=cluster http://sources.redhat.com/cgi-bin/cvsweb.cgi/cluster/cmirror-kernel/?cvsroot=cluster Kind regards, Bryn. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iD8DBQFFv75U6YSQoMYUY94RAvV0AKDYsv7/03Md7xXfpxWLvJEBorsnkwCgpzBV ZDY+hYI4ndG8YepobkLXhyQ= =qL0X -----END PGP SIGNATURE----- -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
