when does a raid rebuild failed
hi, all!
I am using mdadm to create raid on a jbod. Sometimes the rebuild process of the raid failed, and some of the active disks became faulty. Does someone konwns when a disk will become faulty? How does a raid that is created by mdadm failed? What is the process of the raid that is rebuilding.
Very appreciate for any advice.

Running 'smart' on a disk in the jobd will tell you if the disk itself is showing signs of becoming faulty. There are also other possible causes, including controller failure and bad cables. I'd need more information about what exactly is failing, and how, before I can give you a better answer.

Usually because a drive failed. See my previous answer for why.

Not sure what you mean. We need a bunch more information about what is failing, logs showing what is happening, etc before we can really begin to offer any answers.
