Greetings -
I am continuing testing my new Linux Mint installation that only boots to a
grub prompt. After some assistance here a few weeks ago I decided to do a
fresh installation, which appears to have resolved a few of my issues but not
all of them. My system specs are:
Dell Precision 3610
LSI MegaRAID SAS 9271-8i raid controller
Two 3TB drives configured in RAID 1
Single drive recognized by BIOS and Mint Installer as /dev/sda
Before doing the fresh installation, I used SystemRescueCD to wipe the drives
of previous installation using the following commands
root# dd if=/dev/zero of=/dev/sda bs=512 count=1
root# shred -vfz -n 3 /dev/sda
Created partitions and lvm logical volumes in GParted and command line from
SystemRescueCD prior to install
/dev/sda1 550MB /boot/efi fat32 set boot and esp flags
/dev/sda2 550MB /boot XFS
/dev/sda3 2.73TB LVM PV
left 100MB unallocated at the end of the LVM partition
volume group vg_jab
lv_mintroot 8GB / XFS
lv_mintvar 4GB /var XFS
lv_mintswap 2GB [swap]
lv_minthome 80GB /home XFS
lv_mintgis 1000GB /gis XFS
Upon first boot the system went immediately to a grub prompt screen. Using
SuperGrub2 disk the linux mint kernel appears in the menu and selecting it
results in the system fully booting. I have not made any changes to the system
and have just tried to view and probe for diagnostic information at this point.
I have included links to my diagnostic information below. Most everything
looks fine from my untrained eye, except the reference to hd1 on the grub
settings screen shot. Since the BIOS and the installer only recognized
/dev/sda as present, I don't know what is providing the reference to hd1 on the
grub screen, especially since I wiped the drive before beginning the
installation. Could this possibly be due to the 100MB of unallocated space I
left at the end of my raid disk? The bootinfoscript output shows reference to
/dev/sdb but that is the USB stick that was plugged in to the system to run the
script. I can keep doing different installations to try different things, but
I don't want to just try random things without some direction in testing
something specific. I have not tried a manual grub-install yet as I didn't
want to mess with anything that might identify the original problem.
If someone can give me pointers as to what to look for, or to try next I would
appreciate it. You may cc me directly as I am only subscribed to the daily
digest. Thanks.
