Hi,
Below is the output from the mdadm -E option for my 3 partitions in a
raid array.
As you can see, each drive disagrees with the state of the array.
No matter what I try, I cannot seem to get the array back in sync again.
One sees this:
this 0 8 19 0 active sync /dev/sdb3
0 0 8 19 0 active sync /dev/sdb3
1 1 8 35 1 active sync /dev/sdc3
2 2 8 51 2 active sync /dev/sdd3
this 1 8 35 1 active sync /dev/sdc3
0 0 0 0 0 removed
1 1 8 35 1 active sync /dev/sdc3
2 2 8 51 2 active sync /dev/sdd3
this 1 8 35 1 active sync /dev/sdc3
0 0 0 0 0 removed
1 1 8 35 1 active sync /dev/sdc3
2 2 8 51 2 active sync /dev/sdd3
How do I get them all to agree which one has been removed?
I get errors like, when I try to remove /dev/sdb3 from the array it
does not let me, saying it is already removed.
when I try to add it, it says the drive is already in use.
Kind Regards
James
