I just tried to issue a few commands to a new server and received I/O errors: |
2 |
|
3 |
# ls -la |
4 |
bash: /bin/ls: Input/output error |
5 |
|
6 |
So, I checked out /proc/mdadm and saw that one of my drives seems to have |
7 |
failed: |
8 |
|
9 |
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4] |
10 |
md1 : active raid1 sdb1[1] sda1[0] |
11 |
112320 blocks [2/2] [UU] |
12 |
|
13 |
md3 : active raid1 sdb3[2](F) sda3[0] |
14 |
308255104 blocks [2/1] [U_] |
15 |
|
16 |
My question is, "which one?" Usually I get a [UU] on a good RAID, and an _ |
17 |
for the failed drive. That would indicate that sda3 has failed. However, |
18 |
sdb3 is marked with an (F), which I've never seen before. |
19 |
|
20 |
Which drive should I replace? |
21 |
|
22 |
Also, why did I get an I/O error? Shouldn't my RAID have just failed over |
23 |
silently? |
24 |

Last point of information is this from /var/log/messages: |
