I just tried to install 10.04 amd64 server on a box with 3 500G WD and 1 500G Hitachi Drives. I wanted to setup Raid 5 and then LVM for all the partitions. I used the latest ISO files.
Raid 5 for sda1,sdb1,sdc1,sdd1 LVM named system: /, /boot, /home, /var, /tmp, /usr, /usr/local, /opt After installation and the box rebooted, I got error and initramfs prompt. ALERT!! /dev/mapper/system-root does not exist. Dropping to a shell! cat /proc/cmdline BOOT_IMAGE=/vmlinuz-2.6.32-21-server root=/dev/mapper/system-root ro quiet cat /proc/mdstat and I saw that md0 raid 5 with sd[abcd] is resyncing... ls /dev/mapper control ls /dev/md* /dev/md0p1 /dev/md0 As you can see there is no system-root and etc under /dev/mapper. I saw that in /etc/mdadm/mdadm.conf ARRAY /dev/md0 level=raid5 num-devices=4 UUID=........ ls /dev/disk/by-* /dev/disk/by-id/ /dev/disk/by-path As you can see there is no /dev/disk/by-uuid in /dev/disk. Previously, I encountered similar problems when installed on a system with 2 250GB WD disks (1 big Raid1 and then LVM all partitions). I then tried to set 3 Raid 1 small partitions for swap, / and /boot and 1 big Raid1 on LVM for other partitions. With this set up, 10.04 amd64 server was able to successfully booted up. This is a very serious bug considering that a lot of people will be running server edition with some types of RAIDx and the installation failed to correctly set these up. This bug is a show stopper and makes users pondering the quality of each Ubuntu releases. -- mount: mounting /dev/md0 on /root/ failed: Invalid argument https://bugs.launchpad.net/bugs/569900 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
