RAID 10 data recovery


I have built PC with 5 HDD, 1st one has OS and i I have configured RAID 10 on other 4 HDD. I have 6th HDD and would like to test if RAID works


1. when I replace RAW HDD with one of 4 RAID HDD, system boots and says loading GRUB WITH blinking cursor.

2. If I remove HDD in RAID, system goes to grub prompt

I am wondering how to test if my RAID is working, can any one guide me process how to rebuild . I hope it should be easy.

I have installed RAID 10 as part of redhat 5 installation

I would suggest installing webmin web based control panel for Linux. There is also part in Hardware to setup RAID's.

For control, type "cat /proc/mdstat" and it will show you basic data bout all installed RAID's.

There is also "mdadm --detail /dev/md0" for more detailed status page for specific RAID sest.

actually, I did a mistake, instead of testing by removing hdd from raid array, I removed OS, thats the reason it went to grub prompt.

after I corrected my self, it reconstructed RAID automatically on boot up

Thank You for your response.
