I have this problem after doing an install from the alternative CD 11.10 so it'snot just isolated to the live CD.
mdadm may well have been removed for speed reasons, but then Disk Utility needs to fail gracefully and not as it does show that mdadm completed successfully. Please don't be fooled that everyone that might come across this can fix it, I have never done raid on Linux before and I am still learning, and struggling after 2 days (i.e. 2 days after first attempting to create an RAID array its still not functional). Issues like mdadm and Disk Utility not working nicely together, do indeed make me wish for the days when I used to do this in Windows with a huge amount of comparative ease. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/440831 Title: RAID creation fails due to absent package "mdadm" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-disk-utility/+bug/440831/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
