Hello,
One of my HDD on a 2 drive RAID1 md (linux software raid) is intermittently clicking. When this occurs, I can hear a loud clicking noise at uniform intervals and then it stops. Its like "click..click........click..click........click..click........click..click". You know what I mean
It does it about 4 times per hour. I believe this drive is about to die.
Until I find a replacement drive, can I run into problems with the data on the array? I believe the mdadm utility would tell me if the drive was faulty and once I replace the drive, it would auto rebuild the array (re=copy the data to the new drive)?
Can anybody confirm this? I have over 1.2TB of data on this array I really dont want to lose everything...
thanks!
