Linux Drive Device Down
I ran the following in a linux server. One physical drive is down. I believe is sdd drive. Before we order another physical drive. Can someone suggest any utilities to see if the drive can be repaired and put into the raid.
[root@r101s0u1bak ~]# cat /proc/mdstat

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
It looks like RAID1 array[sdc & sdd].
You can use mdadm command utility to check the rebuilding/repairing process.
