The 39Gi/node Longhorn data disks at 1:1 over-provisioning can't fit the media stack (plex 20Gi replica failed: 'insufficient storage'). Volumes are thin-provisioned config-only, so 200% lets the full catalog fit without a disk resize; physical fill risk is low. Also right-sized plex config (20Gi was excessive for metadata). Prod-grade path: grow the data disks (WS-STORAGE follow-up).

# BULK MEDIA (spec bulk-tier requirement, docs/04) — OPEN PREREQUISITE, intentionally NOT declared
|
|
# here yet (the requirement ID is cited in the WS-APPS report, not as a token here: this change does
|
|
# NOT exercise the bulk tier, so it must not be selected as a "touched" requirement whose in-cluster
|
|
# conformance test is still a Phase-1 gap).
|
|
# The Plex library belongs on the `bulk` tier (docs/04 / docs/13 cross-cutting note: metadata DB
|
|
# on replicated Longhorn, large library on bulk). The `bulk` StorageClass exists
|
|
# (platform/longhorn/storageclasses.yaml) and the schema+renderer both support `class: bulk`, but
|
|
# that class is a documented STUB: OQ-2 (external NFS/SMB backing) is UNRESOLVED and the NFS CSI
|
|
# driver is not installed, so a `bulk` PVC will not bind and would leave the Plex pod Pending.
|
|
# To onboard the running Plex shell now (compute + config + public exposure), the media volume is
|
|
# omitted. Once OQ-2 is resolved and `bulk` provisions, attach the library with a one-line add:
|
|
# storage:
|
|
# - name: media
|
|
# class: bulk # external mount; size omitted (sized outside the cluster)
|
|
# then re-render. See the WS-APPS report for the full bulk-media finding.
