Hello.
I setup my test server box using MDADM raid for user data.
I need information how to disable "hdd cache".
I don't want loose any data in case of power fault ( we have backup power) but, in case power supply failure.
I know that default HDD (based on sata) and MDADM lose all data stored in cache memmory when power goes down.
Can you give me any docs about this case and how to prevent, (disable cache)?
regards
