The following tests must be run at least before releasing a new SRPT version:
|
|
|
|
* Make sure that SRPT compiles and installs without triggering any
|
|
compiler warning. Use the following command to compile and install SRPT:
|
|
|
|
for d in scst srpt; do make -C $d -s clean && make -C $d -s install; done
|
|
|
|
* Verify the output of run-regression-tests for kernel versions starting at
|
|
2.6.23 up to and including the latest released kernel.
|
|
|
|
* Verify that SRPT compiles, installs and works fine when following the
|
|
instructions in README.ofed for the latest released OFED distribution and
|
|
at the latest released CentOS, Ubuntu and openSUSE distributions.
|
|
|
|
* Verify that module loading and unloading works fine.
|
|
|
|
* Verify that rejecting logins does not trigger a memory leak, e.g. as follows:
|
|
* Run the following command on the target system:
|
|
${SCST_TRUNK}/scripts/monitor-memory-usage | tee memlog.txt
|
|
* Run the following command on the initiator system:
|
|
for ((i=0;i<100000;i++)); do echo 'id_ext=0002c9030003cca2,ioc_guid=0002c9030003cca2,pkey=ffff,dgid=fe800000000000000002c9030003cca3,service_id=0002c9030003cca3' >/sys/class/infiniband_srp/srp-mlx4_0-1/add_target ; done
|
|
|
|
* Verify that an I/O stress test runs fine by running the following command
|
|
where $dev1 and $dev2 are device nodes created by the SRP initiator and go
|
|
over different IB connections to the target:
|
|
|
|
for dev in $dev1 $dev2
|
|
do
|
|
fio --bs=4K --buffered=0 --rw=write --ioengine=psync --verify=sha256 \
|
|
--verify_fatal=1 --loops=1000 \
|
|
--name=partition1 --filename=$dev &
|
|
done
|
|
|
|
* Verify that the following I/O stress test runs fine:
|
|
|
|
mkfs.ext2 $dev
|
|
mount $dev /mnt
|
|
while true; do { sleep 30; killall fio; } & { rm -rf /mnt/test* && fio --verify=md5 -rw=randwrite --size=10m --bs=4k --loops=1000000 --iodepth=64 --group_reporting --sync=1 --direct=1 --norandommap --ioengine=psync --directory=/mnt --name=test --thread --numjobs=80; }; done
|
|
|
|
* Another I/O stress test:
|
|
(initiator) Write data pattern:
|
|
lmdd if=internal of=/dev/sdb opat=1 bs=1M count=1000
|
|
(target) Verify data:
|
|
lmdd if=/dev/exported-block of=internal ipat=1 bs=1M count=1000 mismatch=1
|
|
(initiator) Verify data:
|
|
lmdd if=/dev/sdb of=internal ipat=1 bs=1M count=1000 mismatch=1
|
|
for ((i=0;i<40;i++)); do lmdd if=/dev/sdb of=internal ipat=1 bs=1M count=1000 mismatch=1 & done
|
|
|
|
* Verify that a SCSI reset works properly by running the following command
|
|
on an initiator system:
|
|
|
|
sg_reset -d ${initiator_device}
|
|
|
|
* Run the following command on a target system:
|
|
|
|
while true; do /etc/init.d/scst stop; sleep 3; /etc/init.d/scst start; sleep 5; done
|
|
|
|
and the following commands on an initiator system:
|
|
|
|
target_id="id_ext=0002c9030003cca2,ioc_guid=0002c9030003cca2,dgid=fe800000000000000002c9030003cca3,pkey=ffff,service_id=0009030003cca2,ioc_guid=0002c9030003cca2,dgid=fe800000000000000002c9030003cca3,pkey=ffff,service_id=0002c9030003cca2"
|
|
while true; do date; rmmod ib_srp; modprobe ib_srp; echo "${target_id}" > /sys/class/infiniband_srp/srp-mlx4_0-1/add_target; sleep 2; done
|
|
|
|
and verify that nothing unexpected happens.
|
|
|
|
* Log in twice from an initiator system, and verify that the first session
|
|
receives a DREQ upon the second login:
|
|
|
|
target_id="id_ext=0002c9030003cca2,ioc_guid=0002c9030003cca2,dgid=fe800000000000000002c9030003cca3,pkey=ffff,service_id=0009030003cca2,ioc_guid=0002c9030003cca2,dgid=fe800000000000000002c9030003cca3,pkey=ffff,service_id=0002c9030003cca2"
|
|
dmesg -c
|
|
echo "${target_id}" > /sys/class/infiniband_srp/srp-mlx4_0-1/add_target
|
|
dmesg -c
|
|
echo "${target_id}" > /sys/class/infiniband_srp/srp-mlx4_0-1/add_target
|
|
dmesg -c
|
|
echo "${target_id}" > /sys/class/infiniband_srp/srp-mlx4_0-1/add_target
|
|
|
|
* Test low memory conditions: load SRPT, reduce the amount of available
|
|
memory by creating a large file on a tmpfs file system and run a stress test
|
|
on an initiator system.
|
|
|
|
* Test the state machine for SCST commands in SRPT by using SCST's error
|
|
injection mechanism. Add the following to scst/src/Makefile, log in from
|
|
an initiator system and trigger SRP I/O:
|
|
EXTRA_CFLAGS += -DCONFIG_SCST_DEBUG -g
|
|
EXTRA_CFLAGS += -DCONFIG_SCST_DEBUG_TM -DCONFIG_SCST_TM_DBG_GO_OFFLINE
|
|
|
|
* Test with multiple values of ib_srp_tablesize in the range 1..128.
|
|
|
|
* Verify that the initiator does not lock up while running the command:
|
|
|
|
fio --bs=512 --buffered=0 --ioengine=sg --rw=read --invalidate=1 --thread --numjobs=8 --loops=10 --gtod_reduce=1 --group_reporting --name=/dev/sdb --filename=/dev/sdb
|
|
|
|
when target processing is delayed by the following command:
|
|
|
|
echo 15 > /sys/module/ib_srpt/parameters/interrupt_processing_delay_in_us
|
|
|
