# ks2 decommission — final checklist
|
|
|
|
Status: **prepared — execute only when every gate in
|
|
[plan.md](plan.md) is ticked.** Rental ends **Sep 30, 2026**; leave a
|
|
few days of margin.
|
|
|
|
## Preconditions (the plan's release gates)
|
|
|
|
- [ ] plakar S3 leg running nightly for ≥ a week, `done (rc=0)`,
|
|
restore test passed ([plakar-s3-data.md](../ks4/plakar-s3-data.md) §7)
|
|
- [ ] nuc pull leg seeded and one instance test-restored
|
|
([nuc-seed.md](nuc-seed.md))
|
|
- [ ] local leg (sdb5) cron green in `/var/log/incus-copy.log`
|
|
|
|
## 1. Cut the last flows to ks2 (root on ks4)
|
|
|
|
```sh
|
|
crontab -e # delete the 04:00 incus-backup.sh line (164.132.173.57)
|
|
incus remote list # if a "ks2" remote is still defined:
|
|
incus remote remove ks2
|
|
# drop the rsyncbackup SSH key if it exists only for ks2:
|
|
ls /root/.ssh/id_rsyncbackup* && rm -i /root/.ssh/id_rsyncbackup*
|
|
```
|
|
|
|
## 2. Last look at ks2 before wiping (root on ks2)
|
|
|
|
```sh
|
|
# anything in the rsync tree newer than the plakar cutover?
|
|
find /backup/ns3061243 -newermt '2026-08-23' | head
|
|
# pre-2023 dirs (catc, mythoughts, qcm, scripts): instances still
|
|
# exist stopped on ks4 — spot-check nothing unique remains:
|
|
ls /backup/ns3061243/{catc,mythoughts,qcm,scripts}
|
|
```
|
|
|
|
Archive anything unique to the plakar dump dir on ks4 (it rides the
|
|
nightly `dumps` snapshot to S3 for free once it stops changing).
|
|
|
|
## 3. Wipe and terminate
|
|
|
|
```sh
|
|
# on ks2 — destroy the data (both pools hold copies of personal data):
|
|
zpool destroy backup && zpool destroy data
|
|
# optional: shred the OS disks via OVH rescue mode / reinstall
|
|
```
|
|
|
|
Then in the OVH manager: cancel the ks2 (Kimsufi) server before the
|
|
renewal date.
|
|
|
|
## 4. Post-mortem cleanup
|
|
|
|
- [ ] Update [doc/README.md](../README.md): remove ks2 from the ks4
|
|
durability bullet and the index line for `ks2/`s "being
|
|
decommissioned" wording (keep the folder as history)
|
|
- [ ] Retire `scripts/incus-backup.sh` + `incus-backup.db` in the repo
|
|
(superseded by `scripts/plakar-backup.sh`) — keep for reference,
|
|
note the retirement in their headers
|
|
- [ ] `login` container cleanup parked in
|
|
[plakar-s3-data.md](../ks4/plakar-s3-data.md): `dropdb outline`,
|
|
remove native postgres
|
|
- [ ] Mark the ks2 line in `plan.md` done, date it
|
