Neutron drive: Build a broken mirror, add second drive later
[See http://www.gagme.com/greg/linux/raid-lvm.php Managing RAID and LVM with Linux] For install onto RAID see also some of the steps here Install on partitionable RAID1
Here are the commands that I used.
# Use the entire drive and put the partitions inside /dev/md_d0 mdadm --create --metadata=0.90 --level=mirror --raid-devices=2 /dev/md_d0 /dev/sda missing # put RAID1 into LVM2 pvcreate /dev/md0 vgcreate vg_mirror /dev/md0
# later, set up second drive as the mirror mdadm --add --verbose /dev/md0 /dev/sdb2 # the mirror should automatically be added to LVM since it's part of /dev/md0
Revo drive: completely managed under LVM2
pvcreate /dev/sdc1 /dev/sdd1 vgcreate vg_workspace /dev/sdc1 /dev/sdd1 lvcreate -l ????? vg_workspace -n lv_workspace mkfs.ext4 /dev/vg_workspace/lv_workspace
After installing OS, /dev/vg_workspace/lv_workspace will be mounted at /workspace
3Ware RAID5: completely managed under LVM2
pvcreate /dev/sd? vgcreate vg_raid /dev/sd? lvcreate -l ????? vg_raid -n lv_var mkfs.ext4 /dev/vg_raid/lv_var
After installing OS, /dev/vg_raid/lvm0 will be mounted at /var
Black drive: completely managed under LVM2
Might also want some SWAP on here?
parted set up one LVM partitions mark partition type as 8e = LVM pvcreate /dev/sdd vgcreate vg_bulk /dev/sdd lvcreate -l ????? vg_bulk -n lv_home lvcreate -l ????? vg_bulk -n lv_swap mkfs.ext4 /dev/vg_bulk/lv_home mkswap /dev/vg_bulk/lv_swap
Will be mounted as /home and swap
Commands to view what we've done
For example:
pvdisplay vg_bulk lvdisplay lv_home lvdisplay lv_swap
