[Lustre-discuss] Bad lmm_size during open replay for inode

[Frederik Ferner]

Hi List,

during a planned MDT fail over today, we got a number of these messages 
below, can anyone explain what this could be?

> Nov 23 08:33:26 cs04r-sc-mds01-01 kernel: Lustre: 21054:0:(mds_open.c:367:mds_create_objects()) Bad lmm_size during open replay for inode 111003141

Searching for this message produced only Lustre source code.

This is using Lustre 1.8.3-ddn3.3 on all servers and most clients, some 
clients use 1.8.4.

So far we've not noticed any ill effect but would like to know what that 
message is and if we can safely ignore it.

Kind regards,
Frederik
