Hi All,

Please help me the following questions.

How many RAID device we can create in RHEL4?

How we find out whether our hard disk is going bad or it has error?

Hello,

Per our forum rules, all threads must have a descriptive subject text. For example, do not post questions with subjects like "Help Me!", "Urgent!!" or "Doubt". Post subjects like "Execution Problems with Cron" or "Help with Backup Shell Script".

The reason for this is that nearly 95% of all visitors to this site come here because they are referred by a search engine. In order for future searches on your post (with answers) to work well, the subject field must be something useful and related to the problem!

In addition, current forum users who are kind enough to answer questions should be able to understand the essence of your query at first glance.

So, as a benefit and courtesy to current and future knowledge seekers, please be careful with your subject text. You might receive a forum infraction if you don't pay attention to this.

Thank you.

Well how many RAID devices you want?

Check the output of the below command:

Code:

cat /proc/mdtstat

You will see an F along side the name of the disk for a RAID array in case of a disk failure. Also, you can see /var/log/messages for possible disk failures.
