# Cluster Revamp Migration TODO
|
|
|
|
Track migration progress from GlusterFS to NFS-based architecture.
|
|
See [CLUSTER_REVAMP.md](./CLUSTER_REVAMP.md) for detailed procedures.
|
|
|
|
## Phase 0: Preparation
|
|
- [x] Review cluster revamp plan
|
|
- [ ] Backup everything (kopia snapshots current)
|
|
- [ ] Document current state (nomad jobs, consul services)
|
|
|
|
## Phase 1: Convert fractal to NixOS (DEFERRED - do after GlusterFS migration)
|
|
- [ ] Document fractal's current ZFS layout
|
|
- [ ] Install NixOS on fractal
|
|
- [ ] Import ZFS pools (double1, double2, double3)
|
|
- [ ] Create fractal NixOS configuration
|
|
- [ ] Configure Samba server for media/shared/homes
|
|
- [ ] Configure Kopia backup server
|
|
- [ ] Deploy and verify fractal base config
|
|
- [ ] Join fractal to cluster (5-server quorum)
|
|
- [ ] Update all cluster configs for 5-server quorum
|
|
- [ ] Verify fractal fully operational
|
|
|
|
## Phase 2: Setup zippy storage layer
|
|
- [x] Create btrfs subvolume `/persist/services` on zippy
|
|
- [x] Configure NFS server on zippy (nfs-services-server.nix)
|
|
- [x] Configure Consul service registration for NFS
|
|
- [x] Setup btrfs replication to c1 (incremental, 5min intervals)
|
|
- [x] Fix replication script to handle SSH command restrictions
|
|
- [x] Setup standby storage on c1 (`/persist/services-standby`)
|
|
- [x] Configure c1 as standby (nfs-services-standby.nix)
|
|
- [x] Configure Kopia to exclude replication snapshots
|
|
- [x] Deploy and verify NFS server on zippy
|
|
- [x] Verify replication working to c1
|
|
- [ ] Setup standby storage on c2 (if desired)
|
|
- [ ] Configure replication to c2 (if desired)
|
|
|
|
## Phase 3: Migrate from GlusterFS to NFS
|
|
- [x] Update all nodes to mount NFS at `/data/services`
|
|
- [x] Deploy updated configs (NFS client on all nodes)
|
|
- [ ] Stop all Nomad jobs temporarily
|
|
- [ ] Copy data from GlusterFS to zippy NFS
|
|
- [ ] Copy `/data/compute/appdata/*` → `/persist/services/appdata/`
|
|
- [ ] Copy `/data/compute/config/*` → `/persist/services/config/`
|
|
- [ ] Copy `/data/sync/wordpress` → `/persist/services/appdata/wordpress`
|
|
- [ ] Verify data integrity
|
|
- [ ] Verify NFS mounts working on all nodes
|
|
- [ ] Stop GlusterFS volume
|
|
- [ ] Delete GlusterFS volume
|
|
- [ ] Remove GlusterFS from NixOS configs
|
|
- [ ] Remove syncthing wordpress sync configuration
|
|
|
|

|
|
- [ ] Clean up old GlusterFS data (only after everything verified!)
|
|
- [ ] Remove old glusterfs directories from all nodes

**Last updated**: 2025-10-22
|
|
**Current phase**: Phase 2 complete (zippy storage setup done), ready for Phase 3 (GlusterFS → NFS migration)
|
|
**Note**: Phase 1 (fractal NixOS conversion) deferred until after GlusterFS migration is complete
