Greetings -
I have been experimenting with an Linux Mint 17 installation for my desktop
system. This is on a new Dell Precision 3610. After having difficulties
getting the Mint installation to complete (grub2 install failed) with software
RAID (and trying the Intel IMSM fake raid) I finally purchased a good hardware
raid card and installed it in my system (LSI MegaRAID SAS 9271-8i). Now Mint
installs without grub2 install failing during the installation; however, at
first boot I get sent to a grub prompt. After playing around with the
SuperGrub2 Disk I think I have isolated the problem. Here is a description of
my system and what I have found.
1. RAID 1 of two 3-TB drives (entire drives, not partitions)
2. Single drive recognized by BIOS and Mint installer as /dev/sda
3. Created partitions and lvm logical volumes in GParted and command line
prior to install
/dev/sda1 500MB /boot/efi fat32
/dev/sda2 500MB /boot fat32
/dev/sda3 volume group vg_jab (left 100MB unallocated at end)
lv_mintroot 8GB /
lv_mintvar 4GB /var
lv_mintswap 2GB [swap]
lv_minthome 80GB /home
lv_mintgis 1000GB /gis
4. I will be installing Windows 7 as a VM (using KVM) later in an additional
lv.
5. Interestingly df-h does not show /dev/sda2, and ldblk does not show a mount
point for /dev/sda2
6. Grub settings point to hd0, gpt1. In grub I see a message of failure
reading sector ???? from hd1
In SuperGrub2 Disk a linux boot image is not present when selecting Everything.
If I select Everything+ a boot image appears. Individually going through the
options in Extra Grub2 functionality, I get a linux boot image to appear if all
I do is enable grub2's LVM support. I booted from this installed image and
tried running grub-install. A reboot after that did not resolve the issue. It
appears that my grub installation does not have the support for lvm, and it
appears that my root partition being on lvm is likely the problem, as somewhere
along this path I saw grub referencing the UUID that is my lv_mintroot.
I am looking for advice on what might be the best approach to take now. I have
no problems if that means re-doing my partitions and taking / off of lvm. I am
just not sure that is the only problem, or the entire solution, or even the
best solution overall. I would like to hear what my options might be before
going through the reinstallation.
Please cc me directly, as I am only subscribed to the daily digest. Thanks.
