Block checksum mismatch detected in WAFL external cache, block 0

[EVERT_HVA]

Hi,

I've receiving these console warning messages several times a day:

Sun Dec  2 21:17:05 CET [extCache.io.BlockChecksumError:warning]: Block checksum mismatch detected in WAFL external cache, block 0.

Sun Dec  2 23:35:27 CET [extCache.io.BlockChecksumError:warning]: Block checksum mismatch detected in WAFL external cache, block 0.

Mon Dec  3 08:36:37 CET [extCache.io.BlockChecksumError:warning]: Block checksum mismatch detected in WAFL external cache, block 0.

Tue Dec  4 13:13:02 CET [extCache.io.BlockChecksumError:warning]: Block checksum mismatch detected in WAFL external cache, block 0.

Tue Dec  4 15:27:50 CET [extCache.io.BlockChecksumError:warning]: Block checksum mismatch detected in WAFL external cache, block 0.

I can't find any related information about these warnings. Does anyone knows what these messages mean?

P.S. This is on a FAS3240 (HA pair) with 8.0.2P5 7-Mode.

this is a known issue, nothing is wrong, just ignore, is fixed in future ontaps

Ok, thank. If it's a known issue, do you know the BUG ID?

*let me google that for you*

Seems to be fixed in 8.0.4 and 8.1.2... Can you try?

Thank you for the help+link (as Google did not). Will schedule ONTAP update, but as you already told, this message can safely be ignored.
