# Migrate /home from system disk (sda) to dedicated home disk (sdc)
|
|
#
|
|
# Prerequisites:
|
|
# 1. Create and attach disk via gcloud:
|
|
# gcloud compute disks create home-disk \
|
|
# --project=kids-ai-data-analysis \
|
|
# --zone=europe-north1-a \
|
|
# --size=30GB \
|
|
# --type=pd-balanced
|
|
#
|
|
# gcloud compute instances attach-disk data-broker-for-claude \
|
|
# --project=kids-ai-data-analysis \
|
|
# --zone=europe-north1-a \
|
|
# --disk=home-disk
|
|
#
|
|
# 2. Run this script as root:
|
|
# sudo ./server/migrate-home-to-disk.sh
|
|
#
|
|
# What it does:
|
|
# - Formats the new disk (ext4)
|
|
# - Copies all home directories preserving permissions
|
|
# - Updates /etc/fstab for persistent mount
|
|
# - Mounts the new disk as /home
|
|
# - Keeps old data in /home.old for manual cleanup
