Hi guys, I recently set up a software raid5 on ubuntu server using mdadm. I have three 1tb drives raided up, sdb1 sdc1 and sdd1. This is a recent upgrade to my fileserver and while I was migrating my data over from my old drives I had them plugged into the box, naturally.
Now I finished migrating my data across and unplugged my old drives and accidentally unplugged the sata cable for one of the raid drives, then booted up without realizing. The raid obviously did not rebuild itself and I quickly found out what went wrong. I've plugged the drive back in but now the raid will not go back together.
but it says:
mdadm --atuo-detect /dev/sdb1 /dev/sdc1 /dev/sdd1
Please help? This is highly frustrating
could not bd_claim sdb1
