Garage RPC connections have no TCP keepalive enabled. When a connection dies silently (proxy pod restart, NAT timeout, network partition), it's only detected by application-level pings after ~60s (4 failed pings x 15s interval). During this window, the node appears connected but all RPC calls to it fail. Enable TCP keepalive on both outgoing and incoming RPC connections via socket2: - Idle time before first probe: 30s (TCP_KEEPALIVE_TIME) - Probe interval after first: 10s (TCP_KEEPALIVE_INTERVAL) A helper set_keepalive() function avoids duplicating the socket2 setup. Incoming connection keepalive failures are logged as warnings but don't reject the connection. Companion to #1345 (stale address pruning + connect timeout). Together they address both halves of the reconnection problem: faster detection (this PR) and faster recovery.

[ Website and documentation | Binary releases | Git repository | Matrix channel ]
Garage is an S3-compatible distributed object storage service designed for self-hosting at a small-to-medium scale.
Garage is designed for storage clusters composed of nodes running at different physical locations, in order to easily provide a storage service that replicates data at these different locations and stays available even when some servers are unreachable. Garage also focuses on being lightweight, easy to operate, and highly resilient to machine failures.
Garage is built by Deuxfleurs, an experimental small-scale self hosted service provider, which has been using it in production since its first release in 2020.
