Each test in the performance regression test suite creates a pool and a dataset for use. Unfortunately, these tests do not cleanup the pool and dataset correctly once they complete. Each test now kills fio and iostat, destroys the dataset, and finally destroys the pool. Each test also now traps the SIGTERM signal to handle cases where test-runner kills a test. Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Giuseppe Di Natale <dinatale2@llnl.gov> Requires-builders: all Closes #5407

# Description:
|
|
# Trigger fio runs using the random_reads job file. The number of runs and
|
|
# data collected is determined by the PERF_* variables. See do_fio_run for
|
|
# details about these variables.
|
|
#
|
|
# The files to read from are created prior to the first fio run, and used
|
|
# for all fio runs. The ARC is cleared with `zinject -a` prior to each run
|
|
# so reads will go to disk.
