Jira issue: CRDB-67119

Start with pkg/kv/kvserver/logstore/logstore.go and pkg/storage/pebble_batch.go, then trace the reported write failure through the stack trace into Pebble's syncing_file.go. The report only identifies an out-of-disk-space panic and does not define a requested change, reproduction steps, or completion test, so the fix and validation criteria need to be established first.
