Hi, I wonder is ocfs2 suitable for hosting OSD data? In ceph documentation only XFS, ext4 and btrfs are discussed, but looking at ocfs2 feature list it theoretically also could host OSDs: Some of the notable features of the file system are: Optimized Allocations (extents, reservations, sparse, unwritten extents, punch holes) REFLINKs (inode-based writeable snapshots) Indexed Directories Metadata Checksums Extended Attributes (unlimited number of attributes per inode) Advanced Security (POSIX ACLs and SELinux) User and Group Quotas Variable Block and Cluster sizes Journaling (Ordered and Writeback data journaling modes) Endian and Architecture Neutral (x86, x86_64, ia64 and ppc64) Buffered, Direct, Asynchronous, Splice and Memory Mapped I/Os In-built Clusterstack with a Distributed Lock Manager Cluster-aware Tools (mkfs, fsck, tunefs, etc.) ocfs2 can work in cluster mode but it can also work for single node. Just wondering would OSD work on ocfs2 and what would performance characteristics be. Any thoughts/experience?
