Nextcloud's per-user data directories were migrated from swarm-data to hdd-bulk (USB HDD tier) on 2026-07-19, keeping the pre-migration copies as <user>-old-ssd on swarm-data as a rollback net (same pattern as the swarm-nvme migration, issue #6).

Delete once the hdd-bulk copies have proven stable for ~1-2 weeks (target: ~2026-08-02):

cd /mnt/swarm-data/nextcloud/data
rm -rf *-old-ssd

This is what actually reclaims the ~332GiB on swarm-data.

Done — closing.

Verified on the filesystem: no *-old-ssd directories remain under /mnt/swarm-data/nextcloud/data, and swarm-data has drained to 1.7 GiB stored (from ~31 GiB), so the space was reclaimed.

Overtaken by events in the meantime: Nextcloud's data moved again on 2026-08-08, from hdd-bulk to the new swarm-data-ec EC 4+2 pool, and the USB HDD tier was decommissioned entirely (pool deleted, OSDs removed, drives pulled). Current state is data on swarm-data-ec — 408 GiB stored / 601 GiB raw, a 1.47x ratio — confirmed by reading ceph.file.layout.pool on a real file. That migration's own rollback copy (data-hdd-old) has also been deleted.
