  • File Storage
    • Network File System
      • Supports NFSv3 (network file system) and NLM (network lock manager)
      • POSIX compliant
      • Multiple copies in AD
    • Can be accessed from BM, VM, Container Instance in VCN or On-Premise VPN (DRG)
      • Accessible from all ADs in a region
    • Attached to AD
    • Components
      • Mount Target
        • NFS endpoint (IP or DNS name). Used when mounting the file system
        • Single mount point can export many filesystems
        • Has an export set (multiple exports/filesystems)
      • Export
        • File System is exported (made available) through mount target
      • Export Path
        • Uniquely identifies a path to a filesystem within mount target
    • Limits
      • Max filesystem size 8 exabytes
      • 2  Mount Targets per tenant per AD
      • 100 File Systems per tenant per AD
    • Security List
      • Stateful Ingress: TCP 111,2048-2050, UDP 111,2048,2049
      • Stateful Egress: TCP 111, 2048-2050, UDP 111
      • Best practice: create security list but apply to all subnets in VCN
    • Steps
      • Create VCN
      • Create Subnet for FSS
      • Create security list with ingress/egress rules and apply to all subnets in VCN
      • Create subnets for compute instances that will access (NFS clients)
      • Create Mount Target
      • Export File System to Mount target
      • Add Export Options READ, READ/WRITE
      • Mount on compute instance
        • sudo mount 10.0.0.6:/example/path /mnt/mountpointA
