We hit a bug where test suite storage/storagesuite.py fails for SUSE Linux Enterprise 15 SP7.

Relevant logs:

force_run=True,

During the test execution the y/N prompt appears multiple times thus i suspect issue in this call:

lisa/lisa/tools/mdadm.py

Line 40 in 1b827bc

cmd = f"echo y | {self.command} "

results in failure:

Continue creating array [y/N]? mdadm: create aborted.

I believe a better alternative to echo y | could be yes | (https://linux.die.net/man/1/yes) or expect (https://linux.die.net/man/1/expect) or pexpect

@volodymyrkatkalov could you please try this change #3771, thanks!

[volodymyrkatkalov]

@LiliDeng could you kindly please give exact steps on scheduling custom refspec #3771 ?

[LiliDeng]

oh, I am not sure how you install lisa, usually after we clone the code, then git checkout lildeng/fix_4_16_001

[squirrelsc]

@volodymyrkatkalov which step are you stuck on?are you using LISA directly or using AITL?

[volodymyrkatkalov]

@squirrelsc via AITL

[squirrelsc]

@volodymyrkatkalov Thank you for clarifying. @LiliDeng please verify it, if it works, we merge the change, and wait it to be available in AITL.
