Claudio,
I tried doing similar stuffs at my setup and I was not able to see similar
issue as reported by you.
We need to know whether it is specific to SATA disk or generic issue.
Can you please provide me next possible details as mentioned below?
a) How about using different SATA disk instead of which you are using
currently. What is behavior in that case?
b) I did below steps to reproduce things. (Please correct me if anything
missing while mimicking your test case)
mdadm --create --verbose /dev/md0 --level=raid1 --raid-devices=2 /dev/sdc
/dev/sdd
"while true; do smartclt -a /dev/sdX; done;"
I kept running it for 15 min, I could not see any issue in my setup.
Is this correct way of reproducing the issue?
My disk are Seagate ST320000641AS (2TB) FW version CC12.
I am suspecting this issue may be mapped to the end devices also.
Need to clarify this doubt doing some other combinations of experiment. Can you
provide details on my queries to jump next steps of investigation?
