The server is currently experiencing a 2 disk failure and was looking for a way to know if my data is lost or not. I tried searching everyone but I didn't find an answer (I'm sorry - new to this).
I ran (cat /proc/mdstat):
Personalities : [raid10] [raid1] md0 : active raid1 sdb1 sda1 1023936 blocks super 1.0 [2/2] [UU] md1 : active raid10 sdb2 sda2 24558592 blocks super 1.1 512K chunks 2 near-copies [4/2] [U_U_] md2 : active raid10 sdb3 sda3 1926568960 blocks super 1.1 512K chunks 2 near-copies [4/2] [U_U_] bitmap: 15/15 pages [60KB], 65536KB chunk unused devices: <none>
As I know, an underscore means that the disk failed. This RAID 10 is running 4 X 1 TB disks (sg1, sg2, sg3, sg4). How do I know which is stripped/mirrored with same data and if my data is not lost?
Thanks for the help in advance.
