File Storage (CephFS)
CephFS is a POSIX-compliant shared filesystem backed by your cluster. Many clients mount the same filesystem at once, which suits shared home directories, build artifacts, media pipelines, and HPC scratch space.
Mounting
Section titled “Mounting”Mount CephFS with the kernel client or via FUSE. With the kernel client:
mount -t ceph <mon-host>:6789:/ /mnt/cephfs \ -o name=<client>,secret=<key>The monitor host, client name, and key come from your credentials document. For Kubernetes, the Ceph CSI driver provisions CephFS volumes dynamically.
When to choose CephFS
Section titled “When to choose CephFS”- Many clients need shared, concurrent read/write access to the same files.
- You need POSIX semantics (directories, permissions) rather than object or block.
- Workloads such as HPC scratch, CI and build caches, or shared datasets.
