This "partition g-32 not find" error after restart is a known pattern with the hstore backend in distributed deployments. A few things to check:

Startup sequence matters — the correct order is: PD nodes first (wait for leader election) → Store nodes (wait for partition assignment) → Server nodes [1]. If the store starts before PD has fully initialized and assigned partitions, you'll get "partition not found" errors.

PD leader election issue — there's a bug (fixed in PR #2961) where after cluster restart, if PD Raft elects a different leader than before, the cluster can become non-functional due to a NullPointerException in the redirect mechanism [2]. If you're on 1.5.0, check whether this fix is included in your version.

Troubleshooting steps:

1. After starting PD, verify the leader is properly elected before starting stores
2. Check if the store is registered with PD via the /v1/stores endpoint
3. Check partition status via the /v1/partitions endpoint
4. Wait 1-3 minutes after all stores register for partition assignment to complete [3]

If the issue persists, can you share:

• How many PD/Store/Server nodes are in your cluster?
• Did the PD leader change after restart (different node became leader)?
• The full PD and store error logs (the images are hard to parse for specifics)?

This may also relate to a serialization compatibility issue documented in issue #3007 if your data was written by a different version [4].
