The following script can be used from a LiveCD to initially structure a GPT disk properly.
There still seems to be some problem where update-grub is never run when a new kernel is installed, even when correct GPT structure is in place. Be sure to run update-grub after any kernel update for grub.cfg to contain the new kernel. Best to try this script on a victim disk and be sure to change $dev, $fsdev and $mount_point to match your system. Use this test script carefully to avoid data loss on a live disk. _______ da...@home1:~/bin$ cat gpt-setup-example #!/bin/bash # research all these options # tune2fs -I 256 -O sparse_super,filetype,resize_inode,dir_index,ext_attr,has_journal,\ # extents,huge_file,flex_bg,uninit_bg,dir_nlink,extra_isize if [ "$USER" != "root" ] ; then echo "Must run as USER=root instead of USER=$USER" exit 1 fi dev=/dev/sdb fsdev=/dev/sdb3 tune_opts='extents,uninit_bg,dir_index,journal_data_writeback' mount_opts='noatime,data=writeback,barrier=0,nobh,errors=remount-ro' mount_point=/data mount $fsdev $mount_point -o $mount_opts 2>/dev/null filecount=$(find $mount_point -type f 2>/dev/null | wc -l) if [ "$filecount" -gt 0 ] ; then echo "Operation will destroy all data on $mount_point" echo "Remove all files from $mount_point before proceeding" exit 1 fi umount $fsdev 2>/dev/null set -x umount $fsdev 2>/dev/null mkdir -p $mount_point parted -s $dev mklabel gpt # must use <1M as parted (through version 1.8.8.1.159-1e0e) has a bug # where 1M is either converted to 0M or rounded down to nearest block # using kB units seems to circumvent this problem well ###parted -s $dev mkpart primary 0 1.1M ###parted -s $dev mkpart swap 1.1M 8G parted -s $dev mkpart primary 0 1100kB parted -s $dev mkpart swap 1100kB 8G parted -s $dev mkpart primary 8G 28G # tell Grub 2 MBR is big enough to use without blocklists as # using blocklists seems to create a vast array of instabilities parted -s $dev set 1 bios_grub on parted -s $dev unit kB p mkfs.ext4 $fsdev tune2fs -L disk2 -m 1 -o $tune_opts $fsdev e2fsck -pfD $fsdev mount $fsdev $mount_point -o $mount_opts mount -l | grep $fsdev -- update-grub never runs because ubiquity crashed with InstallStepError in configure_bootloader() https://bugs.launchpad.net/bugs/419911 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
