Details

Type: Bug
Status: Closed (View Workflow)
Priority: Major
Resolution: Fixed
Affects Version/s: 10.2(EOL), 10.3(EOL), 10.4(EOL)
Fix Version/s: 10.2.27, 10.3.18, 10.4.8
Component/s: Storage Engine - InnoDB
Labels:
- backup
- encryption

Description

When InnoDB creates an .ibd file, it first writes a dummy page 0 with no information about encryption. This may prevent Mariabackup 10.2.20 or 10.2.21 from copying encrypted data files that were craeted shortly before backup started.

Maybe we should create a 0-byte .ibd file first, and then let page flushing write the first pages? Alternatively, preallocate a zero-filled file and then let page flushing do its job.

A valid page 0 must be written to the created files before writing any other pages. Otherwise, crash recovery cannot work.
