Public bug reported: Binary package hint: mdcfg
using kubuntu 7.04 beta alternate CD: I have three pre-existing RAID devices (created during a previous installation with the same CD) each one a RAID 1 array of two disks. When rebooting from CD to do a fresh install, the arrays are recognized during the partitioning task, but when trying to use them, the installation fails with message "cannot stat device /dev/md/2" (notice a slash before the digit. The correct name is /dev/md2). How to repeat: 1) Using the alternate CD, create three arrays md1, md2, md3, mounted to "/", "/home" and "swap". 2) Finish the installation 3) check that the installation works 4) restart with the same CD in expert mode 5) accept defaults until "load installer components from cd" 6) load the "mdcfg" component 7) accept defaults until "partition disks" 8) within "partition disks", choose "manual" 9) the disks are recognized as "K raid". Select "configure software RAID" 10) when asked if you want to keep the current partition layout and configure RAID, say "yes" 11) after this, you can create a new RAID device, delete and existing one, or finish. 11a) choosing "create a new device" you are informed that no free partitions exist, meaning that the existing layout was recognized. You can use a separate console to verify this with mdadm -D /dev/md0 /dev/md1 /dev/md2 11b) choosing "finish" should then use the existing devices. But you get the "cannot stat device /dev/md/2" error After this error shows up, any further operation results in the same error, and the installation cannot proceed. ** Affects: mdcfg (Ubuntu) Importance: Undecided Status: Unconfirmed -- existing RAID partitions not recognized by mdcfg https://launchpad.net/bugs/95987 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
