fix(seaweedfs): drop volumeSizeLimitMB so multiple collections fit
Cozystack overrides the upstream seaweedfs volumeSizeLimitMB from 1000 to 30000 (30 GB), but the e2e sandbox provisions only a 10 GiB PVC per volume server. With maxVolumes=0 (auto), seaweedfs computes maxVolumes as int(10240 / 30000) → 0, then rounds up to 1, so each volume server can host exactly 1 logical volume. With defaultReplication=001 (one replica on a different node within the same rack) two volume servers share that single volume, giving the cluster a hard limit of one writable collection at a time. Since #2716 added a default bucket-cozy-backups Bucket to every tenant-root, that bucket now grabs the only slot on install. Any second collection — the bucket E2E (bucket-test in tenant-test), a tenant app's own bucket, etc. — sits in 'assign volume: No writable volumes' forever, and mc cp hangs until the test times out. Master logs reflect this clearly: failed to find writable volumes for collection:bucket-... replication:001 ttl: error: No writable volumes and no free volumes left topo failed to pick 1 from 0 node candidates volume_growth.go:135 create 6 volume, created 0: Not enough data nodes found! Lower volumeSizeLimitMB back to the upstream chart default of 1000, which makes a 10 GiB PVC fit ~10 logical volumes per server and unblocks all per-collection bucket workloads on small sandboxes. Production clusters still get plenty of headroom — volume size is a soft cap, not a preallocation. Signed-off-by: Ivan Okhotnikov <[email protected]>
