I am amazed by how unconstrained are the imaginations of some other people. That is a truly astonishing setup. > I have a very big concern of stability.

But OCFS2 is meant to work with local physical storage on a local phyical machine. What's your current setup? > maybe ocfs2 just isn't stable on Ubuntu 16.04.3? I am using > version 1.6.4-3.1 OCFS2 has been extremely stable for many years on very high load share-disk clusters for many users. OpenStack and perhaps newer kernels not necessarily so. Also OCSF2 requires a storage subsystem with specific features and a high degree of reliable operation. It is astonishing but fairly typical that this reports contains no mention of the setup or of the state of the storage subsystem. _______________________________________________ Ocfs2-users mailing list Ocfs2-users@oss.oracle.com https://oss.oracle.com/mailman/listinfo/ocfs2-users
