Public bug reported: I have an old system that is supplied with an Intel Option ROM that does not support > 2tb hard drives. Linux works perfectly on this system and see hard drives bigger than 2tb though. I want to create a raid with imsm metadata format and attach it to another system later. mdadm dosn't let me do this. I try to force raid creating using the "--force" option but it is ignored.
#mdadm --version mdadm - v3.3 - 3rd September 2013 #mdadm --create --verbose /dev/md/imsm --level=5 --raid-devices=3 /dev/sd[b-d] --metadata=imsm --force mdmon: Cannot create this array on device /dev/sdb mdadm: /dev/sdb is not suitable for this array. mdmon: Cannot create this array on device /dev/sdc mdadm: /dev/sdc is not suitable for this array. mdmon: Cannot create this array on device /dev/sdd mdadm: /dev/sdd is not suitable for this array. mdadm: create aborted It seems that it also block one from creating imsm metadata raids on AMD platform or in a virtual machine of any type. Why? Why mdadm control user? The "--force" switch is made for this. Ignore the Option ROM version and create the raid! Its a fake raid after all. ** Affects: mdadm (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1584520 Title: mdadm ignores "--force" switch on Intel Fake Raid To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mdadm/+bug/1584520/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
