Failed to list buckets: Network error: dispatch failure

[majinghe]

When i try to use rc list the bucket from a multiple nodes multiple disks, shows error Failed to list buckets: Network error: dispatch failure.

environment

Multiple nodes multiple disks, 32 nodes, each node has one disk(50GB,xfs), the value of RUSTFS_VOLUMES is http://rustfs-node{1...32}:9000/data/rustfs/mnmd.

rc operation

• set alias

rc alias set rustfs http://rustfs-node{1...32}:9000 xxx xxx

• rc list

rc ls rustfs
✗ Failed to list buckets: Network error: dispatch failure

• rc version

rc --version
rc 0.1.15

other info

If i set the different RUSTFS_VOLUMES value, rc works fine

rc alias set rustfs-new http://20.89.57.212:9000 xiaomageuser xiaomagepass

rc ls rustfs-new

rc mb rustfs-new/test
✓ Bucket 'rustfs-new/test' created successfully.

Where 20.89.57.212 is the LB IP for all 32 nodes.

[overtrue]

Confirmed from the reported command path: rc alias set was accepting http://rustfs-node{1...32}:9000, which is RustFS server volume expansion syntax rather than a single S3 service endpoint. I opened #183 to reject that at alias setup time with a clear usage error, so it no longer gets saved and later fails as a generic dispatch failure.
