- Compare the actual free disk space to the value provided via -storage.minFreeDiskSpaceBytes directly inside the Storage.IsReadOnly(). This should work fast in most cases. This simplifies the logic at lib/storage. - Do not take into account -storage.minFreeDiskSpaceBytes during background merges, since it results in uncontrolled growth of small parts when the free disk space approaches -storage.minFreeDiskSpaceBytes. The background merge logic uses another mechanism for determining whether there is enough disk space for the merge - it reserves the needed disk space before the merge and releases it after the merge. This prevents from out of disk space errors during background merge. - Properly handle corner cases for flushing in-memory data to disk when the storage enters read-only mode. This is better than losing the in-memory data. - Return back Storage.MustAddRows() instead of Storage.AddRows(), since the only case when AddRows() can return error is when the storage is in read-only mode. This case must be handled by the caller by calling Storage.IsReadOnly() before adding rows to the storage. This simplifies the code a bit, since the caller of Storage.MustAddRows() shouldn't handle errors returned by Storage.AddRows(). - Properly store parsed logs to Storage if parts of the request contain invalid log lines. Previously the parsed logs could be lost in this case. Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/4737 Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/4945
