Hello beamin Yes, I'm using mdadm. But I have done everything over the gui. Here my process.
1. First I have delete my fakeraid right at the beginning of startup pc 2. Downloaded alternate Ubuntu CD: http://www.ubuntu.com/getubuntu/downloadmirrors#alternate 3. Started from that CD 4. At partition part choose Software Raid and set up your software raid 5. Go on with installation For additional help maybe the following site can help: https://help.ubuntu.com/community/Installation/SoftwareRAID Like already mentioned. There are some pro and contra between SoftwareRaid and Fakeraid. I'm also not the specialist. Each person has to probably find on it's on out if these is a alternative for him or not. I suppose changing back from SoftwareRaid to Fakeraid as soon the problem is solved is also not so easy or even possible without loosing data. -- Ubuntu 10.04 can't create partition on fakeraid https://bugs.launchpad.net/bugs/568050 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
