Instead of the current soft target, it would help if there was an option available in blktests to test against a NVMe-oF block device provisioned from a real target array (like say an ONTAP array).
I have run block/005 test with a device over Infiniband.
block/005 executes random read 1G that takes more than 30 minutes.
I think it would be better to read less for the network device.
CKI reported nbd/002 failure recently on 6.10.0-rc4, it also can be reproduced on 6.9.

Hi,
Because Android doesn't support pvsync2. Can this test case use another IO engine?
I'm not sure the purpose of the test case. Could you give me some suggestion ?
test_device() {
echo "Running ${TEST_NAME}"
blockdev --getro "$TEST_DEV"
xfs_io -c "pwrite -w -S 0xaa -b 2M 0 2M" -d "$TEST_DEV" >>"$FULL"
dd if="$TEST_DEV" bs=2M count=1 2>>"$FULL" | hexdump
blockdev --setro "$TEST_DEV"
blockdev --setro "$TEST_DEV"
blockdev --getro "$TEST_DEV"
In block/012, blockdev --setro "$TEST_DEV"
is executed twice. Is it for special purpose ?
Hi
On latest 4.14.0-rc5, the _get_pci_dev_from_blkdev function can get 4 pdev, which lead block/011 failed. Could we add "tail -1" at the end to fix it?

I found out that systemd-udevd read it when /dev/nullb0 is created and it increased read-inflight count.
Do you have any idea to solve it?

block/001 (stress device hotplugging) [not run]

it is caused by https://github.com/osandov/blktests/blob/master/common/rc line 33 and 34,

on fedora, modules end with .ko.xz,I hope these two lines can be modified to be compatible with the module naming format of different platforms

After loop/006, the /dev/loop0 /dev/loop1 /dev/loop2

, but can be removed after the loop module remove, not sure if it's one tests issue or kernel issue?

I'm not sure what the pass/fail criteria is or should be for this test. Since this test disables the pci device are we expecting that:
What I am observing is that the nvme driver correvtly identifies transactions as timing out, and removes the device:
nvme nvme0: I/O 14 QID 0 timeout, disable controller
nvme nvme0: Identify Controller failed (-4)
nvme nvme0: Removing after probe failure status: -5
However, once the device is removed, the test fails:
+fio: ioengines.c:289: td_io_queue: Assertion `(io_u->flags & IO_U_F_FLIGHT) == 0' failed.
+fio: ioengines.c:289: td_io_queue: Assertion `(io_u->flags & IO_U_F_FLIGHT) == 0' failed.
+fio: ioengines.c:289: td_io_queue: Assertion `(io_u->flags & IO_U_F_FLIGHT) == 0' failed.
So, what are we testing for here?
Those about
$?
(SC2320) are proof of bad coding, which you should correct...
- https://github.com/osandov/blktests/blob/master/common/multipath-over-rdma#L134
Does this code have any chance of returning different return codes at all? 🤔 🤣[ -n "$1" ] || return $?
I'm sure the rest are similar... 🤣
In that function, if cpu0-4/online is writable, the ALL_CPUS only includes cpu0-3.
Is it intentional?
Not sure if PEBKAC or incompatibility with linux-4.18-rc3

Thanks,
The block/018 use the same read command twice again.
dd if=/dev/nullb0 of=/dev/null bs=4096 iflag=direct count=1 status=none &
dd if=/dev/zero of=/dev/nullb0 bs=4096 oflag=direct count=1 status=none &
dd if=/dev/zero of=/dev/nullb0 bs=4096 oflag=direct count=1 status=none &
Is it for any special purpose ?
Test block/0003 doesn't honor multiple test devices:
# cat config
TEST_DEVS=(/dev/nvme0n1 /dev/zram0)
# ./check block/003
block/003 => nvme0n1 (run various discard sizes) [not run]
/dev/nvme0n1 does not support discard
Other tests like block/004 do:
# ./check block/004
block/004 => nvme0n1 (run lots of flushes)
runtime 31.522s ...
block/004 => nvme0n1 (run lots of flushes) [passed]
runtime 31.522s ... 31.115s

runtime 0.658s ... 0.582s
write iops 54613 ... 63015004 at 2017-05-19 11:06:54
Running check with -d option doesn't work for me. I would have expected that -d takes a list of devices rather than reading some environment variable. Hoewever, even setting TEST_DEVS doesn't seem to work:
[root@g-prime blktests]# TEST_DEVS=/dev/nvme0n1 ./check -d
./check: DEVICE_ONLY specified without TEST_DEVS
Or:
[root@g-prime blktests]# TEST_DEVS=(/dev/nvme0n1) ./check -d
./check: DEVICE_ONLY specified without TEST_DEVS
Or:
[root@g-prime blktests]# sh
sh-4.4# TEST_DEVS=(/dev/nvme0n1 /dev/sdb)
sh-4.4# ./check -d
./check: DEVICE_ONLY specified without TEST_DEVS
sh-4.4# TEST_DEVS=(/dev/nvme0n1 /dev/sdb) ./check -d
./check: DEVICE_ONLY specified without TEST_DEVS

Heya,
bash has the option 'errexit' (invoked via 'set -o errexit'), which will cause the script to abort if a command/line returns 'false'.
This has the nice effect that any errors are catched automatically, and don't have to be checked for.
With that we'll be able to catch silent failures which are currently ignored.
Drawback is that one gets lots of false positive initially, as every command which should be ignored need to be suffixed by ' || true'.
But it's a very good thing for hardening the scripts; I've had quite good experience with that when developing testcases for md_monitor
The loop/009 test fails on older versions of systemd (prior to 241) because the new option --ping does not exist.
Reading through the announcement for systemd 241, we see mention of the new ping option there:

Hi,
In this case, there're two xfs_io write command and two hexdump.
Why don't we only use one time xfs_io and hexdump ?

As discussed in mailing lists, test cases in nvme group fail for nvme_trtype=fc, when relevant modules are unloaded before fc resource cleanup: ref
It is desired to add a test case to trigger the failure, so that the failure gets fixed and prevented.

I was trying to run the batch of tests, and noticed that some tests fail with `device is not a PCI device':
[root@g-prime blktests]# cat config
TEST_DEVS=(/dev/nvme2n1)
[root@g-prime blktests]# ./check -d
cat: /sys/block/nvme2c33n1/dev: No such file or directory
[snip]
block/011 => nvme2n1 (disable PCI device while doing I/O) [not run]
/dev/nvme2n1 is not a PCI device
Looking a bit, I tried to find the logic that decides whether the device is a PCI device or not:
[root@g-prime blktests]# source check
^C
[root@g-prime blktests]# readlink -f $(_find_sysfs_dir /dev/nvme2n1)
cat: /sys/block/nvme2c33n1/dev: No such file or directory
/sys/devices/virtual/nvme-subsystem/nvme-subsys2/nvme2n1
[root@g-prime blktests]# readlink -f $(_find_sysfs_dir /dev/nvme2)
/sys/devices/pci0000:ae/0000:ae:00.0/0000:af:00.0/0000:b0:04.0/0000:b1:00.0/nvme/nvme2/nvme1n1
Okay, the /dev/nvme2
node eventually traces back to a PCI device. Maybe I need to use this one, but this is also not accepted by the framework:
[root@g-prime blktests]# cat config
TEST_DEVS=(/dev/nvme2)
[root@g-prime blktests]# ./check -d
./check: /dev/nvme2 is not a block device
I suspect I'm either using this completely wrong, or something else is broken along the way.

I see the git log shows it's a regression test. If I commit a wrong patch causing the regression fail.
What's the fail symptom or log ?
I found the script only check the output message and exit value.
There is a comment by @axboe at
https://bugzilla.kernel.org/show_bug.cgi?id=201685#c288
to the effect that a test has been added to blktests
to check for the ext4 file corruption issue described. Is that test in this test suite, and if so where is it?

I'm working on this right now; I aim at having as little changes to the check file as possible, so that we could possibly have something working in blktests soon and then I/we could improve on this further.
