Raid 1 question

glennbtn · 11-30-2010, 04:46 AM

Hi all

I am learning software raid 1 with centos 5.5. I created the raid with out any problems and removed the first drive to check there was no problems and it booted. I have installed the old drive back in the system as hdc and need to resync the drives (used old drive as partitions correct) I thought I could use raidhotadd but id does not seem to exist anymore.

Can anyone tell me how I resync the drives in the array hda primary and hdc secondary using mdadm

Thanks

Glenn

You will need to use the 'mdadm' tool / command to re-synchronize the drive. It's rather simple but I'll have to dog up the command.
