GParted has no official "linux raid" support yet (Curtis is working on that currently), so upstream GParted doesn't show these devices.
GParted can put a filesystem on e.g. /dev/md0 (if it's not mounted at that moment of course), and upstream GParted allows that if you launch GParted with that device as a parameter on the commandline. So, I think that to make it easier to format such devices, Ubuntu has added a patch to show them anyway (and other devices not officially supported by GParted too). I suspect this patch causes the errors/warnings you see (I haven't tested that yet). So, in a future (upstream) version of GParted, it will know what to do with "linux raid" devices (maybe it will be available in Ubuntu 9.10). -- gparted says that kernel is unable to re-read the partitiontables on /dev/md devices https://bugs.launchpad.net/bugs/356116 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
