Reuse Datastore PBS Lama di iSCSI

 

Rekap: Reuse Datastore PBS Lama di iSCSI (Tanpa Hilang Data)

Kasus
PBS baru, iSCSI lama berisi datastore PBS sebelumnya, data tidak boleh hilang.

---

1. Login iSCSI

apt install open-iscsi -y
iscsiadm -m discovery -t sendtargets -p 193.168.10.19
iscsiadm -m node --login

Pastikan disk muncul (/dev/sdb).

---

2. Mount iSCSI (cek isi)

mount /dev/sdb /mnt/pbs
ls -la /mnt/pbs

Jika terlihat struktur seperti:

.chunks
.lock
.gc-status
vm

→ itu datastore PBS lama (VALID).

---

3. Daftarkan datastore EXISTING (UI & CLI akan gagal)

UI/CLI menolak karena path tidak kosong (by design).

Solusi resmi: edit config langsung

nano /etc/proxmox-backup/datastore.cfg

Isi:

datastore: nas-backup-19
        path /mnt/pbs

Restart service:

systemctl restart proxmox-backup
systemctl restart proxmox-backup-proxy

Datastore lama langsung muncul di UI.

---

4. Buat mount iSCSI permanen

Ambil UUID:

blkid /dev/sdb

Edit /etc/fstab:

UUID=xxxx  /mnt/pbs  xfs  _netdev,noatime  0  2

Reload:

systemctl daemon-reload

Aktifkan auto-login iSCSI:

iscsiadm -m node -p 193.168.10.19 --op update -n node.startup -v automatic

---

5. Tes final (reboot)

reboot
mount | grep /mnt/pbs

Jika masih ter-mount → PERMANEN & AMAN.
