DESIRED LVM CONFIGURATION (per CLAUDE.md)
|
|
================================================================
|
|
|
|
This system should be configured with the following LVM layout:
|
|
|
|
Physical Volume: /dev/vda2 (or equivalent)
|
|
Volume Group: vg_system
|
|
|
|
Logical Volumes:
|
|
├── lv_root → / 8G (ext4/xfs)
|
|
├── lv_boot → /boot 2G (ext4) - Note: typically not on LVM
|
|
├── lv_opt → /opt 3G (ext4/xfs)
|
|
├── lv_tmp → /tmp 1G (ext4, noexec,nosuid,nodev)
|
|
├── lv_home → /home 2G (ext4/xfs)
|
|
├── lv_var → /var 5G (ext4/xfs)
|
|
├── lv_var_log → /var/log 2G (ext4/xfs)
|
|
├── lv_var_tmp → /var/tmp 5G (ext4/xfs, noexec,nosuid,nodev)
|
|
├── lv_var_audit → /var/log/audit 1G (ext4/xfs)
|
|
└── lv_swap → swap 2G
|
|
|
|
Total minimum disk space required: ~40GB
|
|
|
|
CURRENT STATUS:
|
|
This VM was deployed from a cloud image which uses a single partition.
|
|
|
|
TO IMPLEMENT LVM:
|
|
Option 1: Redeploy using preseed/kickstart with LVM preconfigured
|
|
Option 2: Add additional disk for LVM volumes (safer)
|
|
Option 3: Manual conversion (complex, requires downtime)
|
|
|
|
See /root/lvm-conversion-steps.sh for manual conversion process.

# Step 1: Create backup
|
|
# tar -czf /tmp/system-backup.tar.gz /etc /home /root /var
|
|
|
|
# Step 2: Boot from live CD/rescue mode
|
|
# Cannot be done while system is running
|
|
|
|
# Step 3: Partition disk
|
|
# parted /dev/vda mklabel gpt
|
|
# parted /dev/vda mkpart primary 1MiB 513MiB # EFI/boot
|
|
# parted /dev/vda set 1 boot on
|
|
# parted /dev/vda mkpart primary 513MiB 100% # LVM
|
|
# parted /dev/vda set 2 lvm on
|
|
|
|
# Step 4: Create PV and VG
|
|
# pvcreate /dev/vda2
|
|
# vgcreate vg_system /dev/vda2
|
|
|
|
# Step 5: Create LVs
|
|
# lvcreate -L 8G -n lv_root vg_system
|
|
# lvcreate -L 3G -n lv_opt vg_system
|
|
# lvcreate -L 1G -n lv_tmp vg_system
|
|
# lvcreate -L 2G -n lv_home vg_system
|
|
# lvcreate -L 5G -n lv_var vg_system
|
|
# lvcreate -L 2G -n lv_var_log vg_system
|
|
# lvcreate -L 5G -n lv_var_tmp vg_system
|
|
# lvcreate -L 1G -n lv_var_audit vg_system
|
|
# lvcreate -L 2G -n lv_swap vg_system
|
|
|
|
# Step 6: Create filesystems
|
|
# mkfs.ext4 /dev/vda1
|
|
# mkfs.ext4 /dev/vg_system/lv_root
|
|
# mkfs.ext4 /dev/vg_system/lv_opt
|
|
# mkfs.ext4 /dev/vg_system/lv_tmp
|
|
# mkfs.ext4 /dev/vg_system/lv_home

# mkfs.ext4 /dev/vg_system/lv_var
|
|
# mkfs.ext4 /dev/vg_system/lv_var_log
|
|
# mkfs.ext4 /dev/vg_system/lv_var_tmp
|
|
# mkfs.ext4 /dev/vg_system/lv_var_audit
|
|
# mkswap /dev/vg_system/lv_swap
|
|
|
|
# Step 7: Mount and restore
|
|
# mount /dev/vg_system/lv_root /mnt
|
|
# mkdir -p /mnt/{boot,opt,tmp,home,var}
|
|
# mount /dev/vda1 /mnt/boot
|
|
# mount /dev/vg_system/lv_opt /mnt/opt
|
|
# mount /dev/vg_system/lv_tmp /mnt/tmp
|
|
# mount /dev/vg_system/lv_home /mnt/home
|
|
# mount /dev/vg_system/lv_var /mnt/var
|
|
# mkdir -p /mnt/var/{log,tmp,log/audit}
|
|
# mount /dev/vg_system/lv_var_log /mnt/var/log
|
|
# mount /dev/vg_system/lv_var_tmp /mnt/var/tmp
|
|
# mount /dev/vg_system/lv_var_audit /mnt/var/log/audit
|
|
|
|
# Step 8: Restore data from backup
|
|
# tar -xzf /tmp/system-backup.tar.gz -C /mnt
|
|
|
|
# Step 9: Update /etc/fstab in chroot
|
|
# Step 10: Reinstall bootloader
|
|
# Step 11: Update initramfs
|
|
# Step 12: Reboot
