REGRESSION NOTE
This release has a regression which can affect miner and some client nodes, making it impossible to restart the node, producing an error message like this on startup.
ERROR: creating node: starting node: could not build arguments for function [....] opening backupds: opening log: reading backup part of the logfile: unmarshaling log entry: expected byte array
This is caused by the node creating a corrupted metadata write log. If you encounter this error:
- Remove files in
.lotus[miner]/kvlog/metadata/
directory - Optionally, to avoid this issue from reoccurring, update to
v1.5.3-rc1
- Restart the node
Release announcement
