Measured irv-ml1's storetank against the R750xa's as-bought drives while answering comfy-dev's "does the Ada box have ZFS?" question. - storetank: 1.81 TiB pool, 1.45 TiB used, 80% CAP already, compression off at compressratio 1.00x (safetensors incompressible — no win at recv). comfy-dev's ~112 GB batch is landing into it now. - The R750xa shipped 2x 1.92 TB SATA SSD; mirrored that is ~1.74 TiB, smaller than the pool it receives from. Migration would arrive at ~90% full with no growth room. - Buy list: +2x 2 TB SATA SSD (6 bays free, HBA355i has the ports) -> two mirror vdevs striped, ~3.49 TiB at ~45%, redundancy intact. - Retain vs reclaim irv-ml1's /storetank after cutover: RETAIN recommended, surfaced to the operator. Also corrects branch (b)'s recorded rationale. comfy-dev enumerated all twelve running containers: only comfyui mounts /storetank, so (b) was unavailable during the transition, not structurally. Right conclusion, wrong reason — infra-ops reasoned about the box when the question was about the mount. Memory-only; no version bump per the SemVer SKIP list.
