With the new empty disk installed, it will not yet have the partition layout needed for the RAID configuration. Please send to our ticket system request of disk replacement and agree on the time of work with a technician. Now we can change damaged drive to new one. # mdadm -detail /dev/md127 # cat /proc/mdstat Let's check drive and him partitions, which is included there. Than try to again remove partitions from damaged disk. This will help you to change they status to.
# mdadm -manage /dev/md126 -fail /dev/sdb1 # mdadm -manage /dev/md125 -fail /dev/sdb2 To fix it and remove you must to follow commands: By trying to remove they both arrays you will see this error:
dev/sdb1 and /dev/sdb2 displayed like - devices or resource busy. In this situation need to write only one command: You will see status one of arrays is from massive /dev/md127 and another two of arrays status is. While your drive have, for example only one of three damaged arrays. Another 2 - /dev/sdb1 and /dev/sdb2 is healthy.įor the new drive installation in RAID 1 array at first need to remove damaged disk. In our example, /dev/sdb3 partition is “fail”. To get detailed information about a RAID device, pass the RAID device with the -detail option to mdadm command:īefore we can physically remove the hard drive from system we must mark as “fail” the disk partition(s) from all RAID arrays to which the failed drive belongs. The most detailed information mount point about you can find by using command: If you see a missing “U” - like a then the RAID array is degraded or faulty.įor Example: md125 array (/boot ) consist from sda2,sdb2. Each “U” represents a healthy partition in the RAID array.
To identify if a RAID array or all disk drive has failed, look at the string containing. There are 2 HDD drives 2TB: /dev/sda, /dev/sdb.Ĭheck your failed disk in array by using follow command: We have a dedicated server with CentOS 7 operating system. (CentOS, Debian and Ubuntu)Īdding a new hard drive in an RAID1 ArrayĪ drive has filed in your linux RAID1 configuration and you need to replace it.
