Package: mdadm
Version: 2.6.7.2-3
Followup-For: Bug #539154
Hello, just wanted to report in i have the exact same issue as the others
report. I dont know how to reproduce it, but something is definately wrong.
I can give access to the problematic system if that helps.
I will try to recreate the raid for now, and see what happens.
I have 2 raids spread over 2 disks, md0 is a mirror and md1 is a stripe. There
is only a problem with the stripe the mirror works fine.
