Basic stability assessments

ID	test	tool test	status	owner	notes
III.A.1	Run iozone for 2 weeks on basic client/server operations, using: Both data and metadata options Cached and direct I/O Various mount options	IOzone	done	BULL	Now testing with fsstress and FFSB
III.A.2	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	New
III.A.3	Run NFS server for 2 wks with random configuration changes, using: 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		OPEN	OSDL
III.A.4	Run connectathon locking tests against NFS server for 2 weeks, using: Multiple client machines Reboot at random Analyze client cache coherency behaviors Analyze locking behaviors		NEW
III.A.5	Run fsstress 2 weeks on basic client/server operations, using: Long list random operations (1000 operations) hight number of process (100)	fsstress	DONE	BULL	1 week
III.A.6	Run FFSB 1 day on basic client/server operations in stress configuration, using: 1 200 000 files 100 directories	ffsb	DONE	BULL	1 day
