ROBUSTNESS TESTING
Basic stability assessments
- Run iozone for 2 weeks on basic client/server operations, using:
- Both data and metadata options
- Cached and direct I/O
- Various mount options
- Run automounter use case for 2 weeks on amd, autofs, and autong, using:
- Large number of maps
- Randomly mount and run workloads on an automounted partition
- use a variety of workloads, such as randomly chosen fs tests e.g. Crashme more
- Run NFS server for 2 wks with random configuration changes, using: Open OSDL
- Interrupt server in various ways (reboot, power cycle, lan fail)
- Change/reexport export rules at random
- Trigger a client workload at arbitrary times
- Analyze client recovery behaviors
- Run connectathon locking tests against NFS server for 2 weeks, using: New
- Multiple client machines
- Reboot at random
- Analyze client cache coherency behaviors
- Analyze locking behaviors
- Run fsstress 2 weeks on basic client/server operations, using: Done (1 week)
- Long list random operations (1000 operations)
- hight number of process (100)
- Run FFSB 1 day on basic client/server operations, using: Done (1 day)
- 1 200 000 files
- 100 directories
Resource limit testing
- Test stability of client in out of pid situation
- Test stability of client in out of disk space on server situation Done
- Test stability of client in out of inode situation
- Test stability of client in out of swap space situation
- Test stability of server in out of pid situation
- Test stability of server in out of memory situation
- Test stability of server in out of disk space situation Done
- Test stability of server in out of inode situation
- Test stability of server in out of swap space situation
Stress load testing
- Run LTP NFS fstress in a std config on each release fsx, fsstress (1hour), ffsb (1hour) In Progress
- Analyze load balancing, failure modes, etc. under different stress loads New
- Destructive testing by measuring point of failure for various loads New
Scalability (robustness)

- Find maximum file size on Linux IA-32 Fsstress, fsx New
- Find maximum number of mounted file systems on client Fsstress, fsx New
- Test robustness on NUMA when scaling CPU, mem, NIC, or disk count New
- Test robustness on SMP when scaling CPU, mem, NIC, or disk count New
- Test correctness of NFS client when backed by a large (>100GB) cachefs New
- Find maximum number exported file systems on server New
- Find maximum size of exported file systems on server New
Recovery from problems while under light/normal/heavy loads
- Test short & long term local network failure (unplugged cable, ifdown eth0, etc.) Open OSDL
- Test short & long duration remote network partition Open OSDL
- Test behavior during crash/reboot of server with clients holding various states Open OSDL more
- Test multiple clients using, locking, etc. same files New
- Test behavior of server with failed storage device New
- Test behavior during crash of client with open delegations and locks New
- Test recovery from denied permission New
- Test recovery from JUKEBOX/DELAY New
- Test recovery from ESTALE New
