Storage release
Bug Fixes
- Pageserver: Added logic to handle unexpected Write-Ahead Log (WAL) redo process failures, which could cause a
Broken pipe
error on the Pageserver. In case of a failure, the WAL redo process is now restarted, and requests to apply redo records are retried automatically. - Pageserver: Added timeout logic for the copy operation that occurs when downloading a data layer. The timeout logic prevents a deadlock state if a data layer download is blocked.
- Safekeeper: Addressed
Failed to open WAL file
warnings that appeared in the Safekeeper log files. The warnings were due to an outdatedtruncate_lsn
value on the Safekeeper, which caused the walproposer (the Postgres compute node) to download WAL records starting from a Log Sequence Number (LSN) that was older than thebackup_lsn
. This resulted in unnecessary WAL record downloads from cold storage.
