I ended up with the following workaround: When setting up the server i configured the following:
0. RAID 10 on /sda /sdb /sdc /sdd 1. /boot / and swap partition are on RAID but NOT IN LVM VOLUME 2. Rest of the RAID space - LVM partition At the end of install, when you get error message: Install grub manually on /sda1 and /sda2 (/sda3 and /sda4 will not let you, cause they're striped) use console to run: # update-grub # grub-install /dev/sda1 # grub-install /dev/sda2 Return to setup and skip installation of grub (you installed it manally) Hope that helps. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1274320 Title: Error: diskfilter writes are not supported To manage notifications about this bug go to: https://bugs.launchpad.net/grub/+bug/1274320/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
