Re: [HPDD-discuss] Lustre error
We are running lustre 1.8.8 on centos 5.8 for the servers and the clients are lustre 1.8.5
on centos 5.5. We have run trouble free with that setup for over a year, the errors we are
seeing now appeared in the last few weeks and on only one OSS. I have goggled the error
and found nothing enlightening.

It would probably be helpful to know which release of Lustre that you are running

We started getting huge numbers of these messages on one of our OSS servers, there are two

Does anyone know what this message is about? Since we started getting them the lustre
system performance has been reduced.
