Hi Ming
I have used Bart's tests on my test bed they should run fine.
Are you using my SRP setup.

Yeah, I am using your SRP setup.

Once the three directories are created, I saw the new failure,
and both ib/srp and dm-mpath has been working well now.

Laurence and Bart, do you have receipt for making the test
working first?

Could you please share your srp-tests script? I may find a IB/SRP

system

to see if I can reproduce this issue and figure out one solution.

Please have a look at https://github.com/bvanassche/srp-test.

Could you provide me the exact command line for the reproduction?

I simply run ./run_tests, and looks it doesn't work.

[root@ srp-test]# ./run_tests
df: ‘/home/ming/git/srp-test/mnt2’: No such file or directory
df: ‘/home/ming/git/srp-test/mnt2’: No such file or directory
Unmounting /home/ming/git/srp-test/mnt2 from
umount: /home/ming/git/srp-test/mnt2: mountpoint not found
df: ‘/home/ming/git/srp-test/mnt2’: No such file or directory
Error: unmounting /home/ming/git/srp-test/mnt2 failed

This means that I have to add the following to the README document:

Run "mkdir mnt1 mnt2 mnt3" before starting the tests.
