Bug ID 950797: ERST and VDO messages during boot

Last Modified: May 17, 2023

Affected Product(s):
F5OS Velos(all modules)

Known Affected Versions:
F5OS-C 1.1.0, F5OS-C 1.1.1, F5OS-C 1.1.2, F5OS-C 1.1.3, F5OS-C 1.1.4

Opened: Oct 02, 2020

Severity: 3-Major


After system startup, dmesg shows the following messages: [ 1.306207] ERST: Error Record Serialization Table (ERST) support is initialized. [ 18.503404] uds: kvdo0:dedupeQ: verifyBufferedData got unexpected data: UDS Error: Corrupt saved component (1030)


ERST is not an error. It means ERST is initialized and although 'E' stands for 'error', the log message is not an error message. The kvdo0:dedupeQ message occurs when the VDO volume is initialized. Since the volume has only been initialized, there's nothing to corrupt. Both messages can be ignored.


Viewing messages after system startup.


These are not error messages, and you can safely ignore them.
