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 number of connections to Linux IA-32 server Fsstress, fsx New
- Find maximum number of files for Linux IA-32 exported file system Fsstress, fsx
- 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
