Topic: Degraded Raid Error on Single Disk [solved]

[4first]

[found issue in bug log with appropriate fix]

I have recently upgraded to 7.1 and am now getting the following email from the server;

A DegradedArray event had been detected on md device /dev/md1

and

A DegradedArray event had been detected on md device /dev/md2

This has co-incided with the addition of a USB drive for use with the backup2 contrib.

I have searched the forums but have not been able to find anything similar

I have run the command mdadm --detail /dev/md1 and 2 with

[root@myth ~]# mdadm --detail /dev/md1

Is this due to the usb disk, something that can safely be ignore of is there something that can be done for this?

thanks

I have the same problem on my server.

How did you solve this problem, cause i can't find the specific bug?

Plugged in a USB drive last week and now I'm finding the same issue.  I found this in the bug tracker:
http://bugs.contribs.org/show_bug.cgi?id=2390
but there seems to be no resolution to the debate at this time.
